Ground Support Equipment

Shock Absorbing Casters

Shock Absorbing Casters are Spring Loaded and designed to absorb shocks and minimize the
impact to the cart, resulting in smoother movement, reduced risk of damage and less noise. 
Ideal for applications where surfaces are not even or flooring has damage or debris.

• Aircraft Ground Maintenance Systems
• Engine Dollies
• Aircraft Jacks
• Max Capacity: 25,000 lbs

Pneumatic and Semi-Pneumatic Wheels

A great choice for outdoor use, especially on rough uneven surface including gravel, cracked
cement, thresholds, and other surface environments. The pneumatic tires cushion the load
and roll over obstructions with ease

• Aircraft Ground Maintenance Systems
• Helicopter Dollies
• Outdoor Use and Wet Environments
• Max Capacity: 7,260 lbs

SoS (Swivel on Swivel) Rigs

The swivel on swivel caster achieves significant reductions in push force that almost no other caster can.
SoS caster is maintenance free, thanks to a kingpinless design and precision ball bearings.
The design also virtually eliminates any side to side shifting when the wheels rotate 180 degrees.

• Get in and out of tight spaces easily
• Minimizes operator fatigue
• Never needs greasing or lubrication
• Max Capacity: 1,800 lbs

TWERGO®

Significant reduction in initial and continuous push force make this caster the ultimate ergonomic
caster. TWERGO® unique tread thickness minimizes friction and eliminates scrubbing and sliding 
when turning, while providing the impact resistance of normal wheels. 

• Reduce initial and continuous push force by 25%
• Designed to last longer with aluminum cores that won’t rust or corrode
• Minimizes scrubbing and dispels debris.
• Max Capacity: 4,200 lbs

TWERGO® Lite

The single wheel version of our extraordinary TWERGO® wheel utilizes the same patented face
design to reduce initial and continuous push force. Ideal for lighter loads that do no require a lot
of turning and maneuvering.

• Durable and strong with a cast iron core
• Ultimate 2″ wide caster wheel
• Higher weight capacity and durability than Balloon/Donut Wheel
• Max Capacity: 1,800 lbs

Modern Suspension

Our subsidiary Modern Suspension offers a completely aluminum line of casters that are ideal
for outdoor applications, aluminum weighs less and is noncorrosive to withstand the elements.
While their extremely rugged and durable steel line offers a greater max capacity per caster.

• Aircraft Maintenance Stand Casters
• Aircraft Engine Stand Casters
• Aircraft Wheel Dolly Casters
• Aluminum Max Capacity: 6,500 lbs
• Steel Max Capacity: 25,000 lbs
