Ground Support Equipment

Ground support equipment is a demanding industry that requires the “beyond standard” durability that Caster Concepts is accustomed to offering. Ground support equipment is utilized to service aircraft before, after, and between flights. There are numerous instruments of ground support equipment that move on wheels such as luggage carts, cargo decks, cargo dollies, and aircraft maintenance stands that must withstand the elements and the wear and tear that this industry faces daily.

Harsh weather environments brought upon by rain and snow, or hot and frigid temperatures make choosing the right caster for your ground support equipment a difficult task. Coupled with the varying weather conditions, is the surface condition of the airport tarmac. Uneven surfaces, cracks in the cement, and obstructions such as rocks or debris can cause for a bumpy ride. This may cause costly damage to your valuable cargo, thus choosing a safe and durable caster for your application is of utmost importance. Caster Concepts supplies casters and wheels for ground support equipment around the world, providing industry-leading motion solutions from the ground up.

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


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


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
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

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

Drive Caster™

Learn More

Drive Caster™

The Drive Caster™ is designed to move tons easily and efficiently, while offering the flexibility to
integrate into a variety of applications, above and beyond industrial carts and racks. This motor driven
caster, is powered by a 1/4hp or 1/2hp electric motor, that can move up to 5,000lbs total weight per caster.

  • The industry’s first motor powered industrial caster
  • Can easily be integrated into most carts, racks and carriers
  • Great for heavy load applications

Conversion Drive Caster

The Conversion Drive Caster converts your existing material handling carts into Motor Powered Carts, 
quickly and easily. Simply remove one swivel caster and bolt in the Conversion Drive Caster and away
you go. Can be used in almost any setting where a manually pushed cart was previously used to move
loads up to 5,000lbs.

  • Convert existing carts into powered carts
  • Fully integrated solution
  • Virtually eliminate risk of overexertion injuries
  • Reduce operators needed to move heavy loads.

Custom Casters

Unique challenges require custom solutions, solutions that are built to exact specifications. Our flexible
manufacturing process enables us to build the exact caster for your needs. If you don’t find the exact caster
for your needs, take a look at our custom CAD configurator, or contact us and we will design and build the
exact caster for your needs.

  • All of our casters are built-to-order and to exact specifications. 
  • We don’t follow the cookie cutter manufacturing system used by other caster manufacturers
  • We offer engineering design services as well as our custom configurator.
  • Design custom CAD models that can easily be integrated into your models.
