monorail dampers


Challenge: Develop dampers to control sway and rocking of vehicle cars in monorails and people movers that operate in all types of weather conditions around the world.

Solution: Custom shock absorbers with unique valving and mounting configurations were engineered to obtain the desired motion control of vehicle cars while being able to perform in various weather environments.

Product: Custom Shock Absorbers

theme park ride semi-custom shock absorbers


Challenge: Spec a damper to control the motion of theme park rides that would provide the desired experience to park visitors while also being serviceable.

Solution: Unique shocks were constructed utilizing standard parts with custom mounting options, making them rebuildable for regular service and keeping R&D costs to a minimum.

Product: Semi-Custom Serviceable Shock Absorbers

mobility chairs


Challenge: Develop an aesthetically pleasing shock that would integrate with the current chair design while providing a better ride and optimizing safety for users.

Solution: Worked closely with OEM engineers to develop a small custom coil-over shock to meet design and performance criteria.

Product: Custom Coil-Over Shock Absorbers

kids playing at the park


Challenge: Create a damper to control the speed at which a piece of playground equipment rotates.

Solution: Leveraged a standard shock with a unique valving system that allows for free motion at low RPM while regulating high-speed rotation.
