Gentle damping for electric scooters
TUBUS bumpers make driving an e-scooter a real experience. The footboard of an electric scooter should be dampened to enable the driver to experience a comfortable ride even over potholes and other bumpy surfaces. Ideally, the characteristic line should be furnished with a soft increase in force over a long stroke. The elegant look of the scooter as well as the folding mechanism designed to save space have not allowed the use of feasible damper solutions up to now. Inferior alternatives such as rubber dampers made of polyurethane or simple steel springs could not be considered from the start. The TUBUS bumper TR52-32H offered the perfect solution with its compact construction design paired with progressive damping action.
Safe braking of maintenance boats
The maintenance of wind turbines in open seas has long resulted in damage to maintenance boats. Because of impact velocity and swell, an increase in the boat's mass of up to 20 percent must be taken into account when landing on a rigid mooring structure. It is only since the landing operation has been carried out with the aid of the ACE company's TUBUS series that cable repair and maintenance work on wind turbines has been made safe for both personnel and equipment. TUBUS of the type TS84-43 are seawater resistant and can withstand ambient temperatures from -40 °C to + 90 °C.
Obstacle end positions secured
In the case of driving safety training, swinging flags are used to simulate the sudden appearance of obstacles. If the driver reacts too slowly, the flags are swung just as quickly away to avoid damage to the vehicle. In order to protect the end positions of this safety system during to and fro motion, ACE miniature shock absorbers of the type MC225EUMH2 are installed. They come with a special side load adapter for use in this situation. Among other things, this improves the ability of the shock absorber to absorb lateral forces during to and fro motion.
Quicker, gentle positioning
ACE industrial shock absorbers optimize portal for machine loading and increase productivity. This device driven by piston rodless pneumatic cylinders, in which two gripper slides are moving independently of each other at speeds of 6.56 ft/sec to 8.20 ft/sec, is equipped with industrial shock absorbers as brake systems. Their function is to stop a mass of 55 lbs up to 540 times per hour. The model MC3350M-1-S was chosen for this application, allowing easy and extremely accurate adjustment of the end positions of the adjustable limit stops. In comparison to brake systems with other function principles, shock absorbers allow higher travel speeds and shorter cycle sequences.
Soft end-of-travel damping on rotary movements
ACE miniature shock absorbers optimize production with minimum expenditure. The cycle rate for an assembly line producing electronic components was increased to 3,600 units/hr. Miniature shock absorbers type SC190M-1 decelerate the rapid transfer movements on the production line and using soft damping methods optimize the pick up and set down of components. This soft deceleration technique has increased production and reduced maintenance on the portal and rotary actuator modules. The optional side load adaptor protects the shock absorber from high side load forces and increases the operating lifetime. Using ACE shock absorbers reduces maintenance costs by 50 % and running costs by 20 %, diminishing energy consumption.
Safe end position damping
ACE TUBUS profile dampers protect the integrated loading station on a new high speed machining centre. The ACE TUBUS damper is designed to prevent overrun on the high speed loading station of a Camshaft machining centre used in the automobile industry. In the event that the drive train fails during operation or incorrect data is inputted the ACE TUBUS damper absorbs the impact preventing costly damage to the machine. The TA98-40 TUBUS damper impressed engineers with this exceptionally long service life in operation. When used as an emergency stop the TUBUS damper can absorb up to 73 % of the impact energy.
ACE industrial shock absorbers offer safety to spare for rotation or braking of a large telescope. The optical system of this telescope for special observations is moveable in two space coordinates. The structure in which the telescope is mounted weighs 33,069 lbs and consists of a turntable with drives and two wheel disks rotating on bearings. It enables a rotation by ±90° from horizon to horizon. To safeguard the telescope in case of overshooting the respective swiveling limits, industrial shock absorbers of the type ML3325M are used as braking elements. Should the telescope inadvertently overshoot the permissible swivel range, they will safely damp the travel of the valuable telescope.
Damping combination SLAB and TUBUS
SLAB-TUBUS-Combination ensures fast luggage transport. Airports endeavour to shorten air passengers’ waiting times as much as possible. This aim is met with a solution especially developed for luggage transport systems and has solved previous damping issue. Transport carriers with a weight of up to 120 kg can now be moved at the desired conveyor belt speeds. A SLAB-combination of the material SL-030-12(25)-Dxxxx together with two TA40-16 type TUBUS profile dampers are used here.
Constant deceleration force
ACE miniature shock absorbers are the right alternative. This pneumatic module for high precision, high speed motion ACE miniature shock absorbers are the right alternative. This pneumatic module for high precision, high speed motion intentionally abandoned pneumatic end-of-travel damping. The compact miniature shock absorbers of the type MC25MH-NB decelerate the linear motion safer and faster when reaching the end-of-travel position. They accept the moving load gently and decelerate it smoothly throughout the entire stroke length. Additional advantages: simpler construction, smaller pneumatic valves, lower maintenance costs as well as reduced compressed air consumption.
TUBUS bumpers safeguard hydraulic cylinders. In a testing facility for vehicle tanks, the test specimens are pulled out of the water with a support arm. A hydraulic cylinder carries out the swinging movement and is attenuated in the end position by two TUBUS TR85-50. Even if this work could be taken over by other absorber solutions, the energy balance clearly speaks for the benefits of the TUBUS bumpers – they are inexpensive, they save space, they are free of leaks due to solid construction and are suitable for underwater functions in the test pool.
MAGNUM protection of carriage construction
Serving a similar purpose, several ACE dampers are installed in Jada, the triple-axis, free-moving badminton robot. In order for the badminton robot to be capable of playing, it must be able to change direction in the shortest time possible. Jada is designed therefore to brake at a maximum of 30 m/s². For this task, linear modules are limited by the use of industrial shock absorbers of the type MC4575EUM-0. Miniature shock absorbers and profile dampers are also installed at the location of the "racket hand". In all cases, the modern ACE machine elements serve to protect the end positions of the construction.
ACE-SLAB damping pads protect man and machine. At the beginning of the construction phase of a modern processing centre at the end position, a 25 kg cable channel collided with force against the housing and produced a deafening noise and mechanical strain on the energy chain. A reliable solution for compliance with the operational parameters was realized with the SL-030-25-Dxxxx type ACE-SLAB damping pads even before the milling machine was finished.
Protection of drive used in space treadmill
When training in zero gravity, a harness with bungee cords is used to ensure that trainees do not become disengaged. Three ACE profile dampers with a linear-working facility are utilized in this case. One so-called TUBUS is positioned in the pneumatic cylinder, while the other two are put in place in the rest of the system. All the dampers have the task of protecting the system if the treadmill drive belts become damaged. Otherwise, the cylinder would reach a very high speed and become seriously damaged at the end of the stroke.
Impact reduction in ring form
ACE-SLAB damping pads make tyre transport safer. Developed for absorbing the impact of forces, the ACE-SLAB damping pads SL-030-121-Dxxxx applied in this tyre testing system are ideal for protecting the sliding parts of the machine during quality tests. The individual customisation of the ring form of the centre arm and simple integration into the equipment also support the decision for applying these innovative absorber elements.
Impact protection for large areas
ACE-SLAB damping pads offer impact protection for wooden battens. To protect wooden battens with differing weights and impact speeds of approx. 2 m/s, the SLAB-material SL-030-12-Dxxxx was screwed across the whole surface between two steel sheets in this application. This creates an even damping effect over the whole impact area, which protects the impact surfaces of the battens from an excessive impact load. The minimisation of recoil as well as reduction of noise are further positive side effects of this construction.
Damping lever motions
ACE rotary dampers protect the keyboard. To provide long term protection in arduous and often dirty industrial applications (and also to protect against unauthorised access) the machine keyboard is installed in a lockable and pivoted housing cabinet. ACE rotary dampers FRN-F1 were installed on the pivot axis to provide a smooth controlled motion to the keyboard as it is pulled down into its operating position. The damper also prevents overloading the hinge system and prevents damage to the keyboard, the housing cabinet and the hinges.
ACE rotary dampers ensure the quiet shuffling of playing cards. Software controlled playing card shuffling machines such as this one are used throughout the world and are equipped with the FRT-G2-101-G1 type rotary dampers. Maintenance-free and ready to install. Before inserting the set of cards, you can ensure the quiet stopping of the plastic wedge in the equipment when it is driven upwards. The dampers can be applied to suit your requirements; clockwise, anticlockwise or in both directions; and they are just as reliable as the open and close slides in high qualitiy DVD or CD players.
Rotary dampers achieve folding success
For his carpentry exam, an aspiring master carpenter created TV/bar furniture in which the bar element is provided with a rotatable 90° bar hatch. Rotary dampers of the type FYN-U1-R/L303 make opening and closing the hatch easier, but also protect it against overloading of the end positions. The brakes also prevent fingers becoming trapped. The so-called limited rotary dampers still find sufficient working angle up to a maximum of 115°. For other cases, ACE has fully rotational rotary dampers available.
Finger protection when cutting bread
To exclude the possibility of injury when using bread slicing machines on self-service counters, the automatic bread slicing process does not start until the flap of the modern machine is closed. To simplify the operation and to thereby increase acceptance of the self-slicing principle among users, two-way rotary dampers of the type FDT-57 ensure smooth opening and closing of the door. Even when rotary dampers must act only in one direction, ACE has appropriate variants readily available.
Invisible protection for cooker hoods
For ergonomic handling, modern cooker hoods can be driven by a motor into an up position and then down again. When driven downwards, an AC load can result in a total loss through current being fed back into the voltage source. One of the tasks of the ACE rotary dampers type FDN-63-R is to prevent this. The modern machine elements are also built to provide protection against motor failure. Sliding the hood down too quickly could lead to further costly damage to the hood and the ceiling console and even cause personal injury.
Feed controls increase speed of ice handbike
The specially-designed handbike wheelchairs experience problems on bends as soon as roads are wet from rain. In order to make speed achievable on ice and not just when travelling in straight lines, a Dutchman developed a special construction. By using gas springs he was able to achieve speeds of 14 km/h on bends. With a gas-filled feed control this speed increased by 50 percent. This is made possible by using a combination of feed control and gas filling to enable an inclined plane to be compensated for within the horizontal range, which is facilitated as the seat of his handbike tilts by 10 to 15 degrees on bends.
Operating speed of flaps top-regulated
In the past, operators of used-clothes containers could sustain injury because the flaps closed relatively quickly and uncontrollably. Various hydraulic dampers of the type HB-15, which are designed specifically for the type of container, regulate the synchronization of the flap in both directions and thereby serve to regulate the operating speed. To accommodate a range of requirements and to provide optimal protection against theft, different types with different strokes are mounted on flaps without damping, on large flaps with damping and on rotor flaps with damping.
Tandemly-operated large flaps securely under control
Underground distribution systems are visually advantageous. To facilitate their servicing, the heavy covers of the often large supply systems are brought back to the surface with the help of ACE industrial tandem gas springs (push type). This is quite easily achieved thanks to the use of two pressure pipes, the result of which is two different force ranges. This means fitters must not endure laborious bending and a downward passage into the system of channels. In addition to these advantages, the springs benefit from their long service life and their capacity to be used, as stainless steel variants, in even the most hygienically-sensitive areas.
Safe opening and closing
ACE industrial gas springs (push type) protect samples in an incubator, which is used for chemical and biochemical applications. The plexiglass hood, under which may be found valuable laboratory goods, is securely held open by two maintenance-free, ready-to-install ACE industrial gas springs (push type) of the type GS-12-60-AA-X . With an end-position damping of 5 mm and an extension force of 10 to 180 N, they help to handle the forces generated. The hood is always easily opened and remains in this position. It also remains securely shut when the incubator is in operation.
Hydraulic dampers bring the sled movement of this textile machine to a gentle stop. At the turning point of 287 lbs reeling spools, a sled should move up and down smoothly without causing a collision at the end of stroke position. The solution was provided by the hydraulic damper DVC-32-100. A self-contained sealed unit, ready to install and maintenance-free these units are ideal for precise control of speeds in both directions of travel. The travel speed is maintained throughout the entire stroke and can be independently adjusted in each direction of travel. Thanks to their compact design and wide choice of mounting accessories, these dampers could be easily integrated into this machine.
Made-to-measure stainless steel gas springs
A special hygiene and toilet chair, designed for children and young people with disabilities, must be firmly lockable in the sit and tilt positions. The practical aid thereby provided for relatives and carers can be attributed to two lockable ACE industrial gas springs (push type) which were especially developed and manufactured for this application and operate on the basis of the so-called tilt-in-space function. This allows the chair to be tilted forwards and backwards and provides significantly more convenience for users and patients. In order to meet all hygiene requirements, the gas springs are constructed in stainless steel.
Doors open and close safely
ACE industrial gas springs make opening and closing doors of rescue helicopters easier. The maintenance-free, sealed systems are installed in the access doors of helicopters of the type EC 135. There, they allow the crew to enter or exit the helicopter quickly, thus contributing to enhanced safety. The GS-19-300-CC gas springs provide a defined retraction speed and secure engagement of the door lock. The integrated end position damper allows gentle closing of the door and saves wear and tear on the valuable, lightweight material.
Swinging movements cushioned by hydraulic dampers
Passengers always feel the swinging movement involved when cable cars arrive at the ski station. Maintenance-free hydraulic dampers type HB-40-300-EE-X-P cushion these movements perfectly. Designers of the cable cars, connected by means of an articulated joint via a four-point frame and connection guide to the suspension rod, profit from the ability of the adjustable dampers to absorb compressive forces of up to 2,248 lbs on either side.
Tandem solution increases strength of gas springs
Industrial gas springs add support to the muscular strength of the user when opening doors, hoods and covers. Standard models however, which are used for example on vehicle hoods and tailgates, are limited by the functional principle on which they are based. ACE provides industrial tandem gas springs (push type) for large and above all heavy elements, which need to be moved and joined together, as they do in this case, in the production of convertible roofs. Success in this case is achieved by synchronising an initial angle of 350° with an opening angle of 80° and a mass of 200 kg, which is accomplished at a handle radius of 850 mm!
Protection under the hood
ACE industrial gas springs prevent injuries during maintenance work on harvesting machines. The blades of corn pickers are arranged under plastic hoods, which assure proper material flow within the machine. For maintenance purposes, the hoods, weighing about 7 kg, must be lifted up. To protect maintenance personnel from injury by falling hoods, they are kept in the open position by industrial gas springs of the type GS-22-250-DD. Another advantage they offer is their stability under rough operating conditions due to their wear-resistant coating on the piston rod and the coated housing.
Isolate low-frequency vibrations
In an opera production a 3D HDD projector was supposed to project images onto the stage during performances. Standing as it did on a trolley, which was to be moved over a tiled floor, the projector was virtually unusable. The problem was solved by combining an increase in the projector frame to 10 kg with the assembly of pneumatic levelling mounts of the type PLM-1. PLM, as part of the ACEolator family, is designed to operate in the low frequency range and is used primarily where perfect isolation of measurement tables, testing equipment and high-performance machines is required.
Effective against sound and vibrations
Interference frequencies in a switch cabinet caused two parallel-connected transformers to vibrate so much that working quietly in adjacent rooms was all but impossible. Because they stood on the ground, it was their weight that caused office staff who worked in the same building to feel the effects first hand. The resulting noise was equally bad. ACE-SLAB plates of the type SL-170-25 Fxxxx reduced the vibration levels of the transformers by 91 percent. Through this application, a pleasant working environment has now been established.
More protection through robust Flex Locs
In the present case, when compared to screw connections, the modern quick connection elements produced by ACE have a distinct advantage: their material makes them resistant to the most diverse range of aggressive media, including salt water. Because of this, they provide protection to the housings which encase emergency pressure canisters that are used for the launch of lifeboats. In the most innocuous scenario, the housings would lose their stability through the effects of rust. In the worst case, damage to the pressure canisters could occur or to the entire davit construction.
Decoupling of ambient vibrations
Measurements made on a glass measuring table led to unusable results because the isolator used was unable to cope with the lateral stiffness of the products used. Only low-frequency pneumatic isolators with automatic level control of the type PAL 21-6 ACE could provide a remedy. A special feature of these membrane pneumatic isolators lies in the level control valve, which has, by virtue of its construction, an above-average longevity. Relatively large acceleration forces can lead to horizontal movements and it is particularly in such situations that the robustness and durability of the isolation system make a significant contribution.
High-level protection of linear modules
Safety shock absorbers produced by ACE are installed in the top linear system models of one of the most prestigious companies in the field of drive and control technology. Their job: to protect the z-axis from damage caused by uncontrolled movements. Various safety dampers are used for different load ranges. Tests have shown that, in the worst case, a collision speed of up to 5 m/s might occur. To be on the safe side, the interpretations were based in all cases on a slightly higher value.
Ideal for use in agricultural machinery
TUBUS bumpers give tele-wheel loaders strong stability. With their function of limiting swinging movement, they secure machines when cornering and loading and provide a high degree of comfort and safety as well as securing the loaders. A further advantage is that the shovel can be loaded up to its full capacity for better performance when levelling and pushing. Small cost, large force absorption: The TUBUS bumper TC design series employed here convinces with its energy absorption in the range of 3,983 in-lbs up to 112,626 in-lbs, whereby the machine elements with diameters of between 2.52 inch and 6.93 inch are very easily integrated into construction designs.
Safe driving in end positions with ACE
The aim was to protect a driving simulation capsule on two of its eight axes. The demands placed on a potential emergency stopper were high because it was clear that its failure would lead to massive damage to the complete construction as well as to the capsule. Even the possibility of damage to the health of the test personnel could not be ruled out and was taken into consideration in a diverse range of mass-speed combinations. Two ACE safety shock absorbers now safely contain destructive forces, e.g. during power outages, and eliminate high risks.
Controlled emergency stop
ACE safety shock absorbers protect precision assembly jigs for the aircraft industry. The basic mount of this coordinate measuring machine for the production of parts in the aircraft industry is made of granite and must not be damaged. To avoid damage from operating errors or mishandling, all movement axes were equipped with safety shock absorbers of the type SCS45-50. If the turntables malfunction the safety shock absorbers decelerate the loads before expensive damage can occur to the granite measuring tables.
