Air/Pneumatic Tire Gantries

EC&MW’s Air tire gantry cranes, also referred to as Pneumatic tire gantries, are manufactured to the same high standards as all of our portable gantry cranes.  Although we were not the first to invent the air tire gantry, we were the first in1998 to formulate and produce lightweight aluminum production models. Several years later other companies caught on to their unique asset to the moving and rigging industry. Their original design was for moving and relocating roof top HVAC systems.  When properly used, it has been noted by customers, for having the ability to minimized/eliminated roof damages.  Later on we evolved the concept to our Animal Rescue portable gantry cranes, as well as Custom Models like the one shown to the right that was designed for UC Davis of Calif.

Uses: Include construction sites where minimal uneven terrain is possible. Why:  With larger diameter air tires they are forgiving on a packed soil terrain.  They are not suitable for sand, gravel and loosely packed rock situations.

Uses: They have also found their way for moving highly delicate electronic instruments.  Why: Air tires provide unparalleled cushioning effect that really no other caster can provide.

Our sister company, Hospital Rigging Supply, originally came out with our first Pneumatic Tire Caster Gantry in 1998.  Others have again followed in our footsteps.  Our pneumatic caster concept is in several of other models of gantries we manufacture.  From our Animal Rescue to Fall Arrest and All-Terrain model gantries.
Now! Which one is better for your application?  Below we have listed pros and cons between models.

500, 1,000 & 2,000 lb. cap. Models
Pros of this model Pros of this model
  1. Multiple casters (8 or 10) over a 60″ to 68″ long base provides less concentration of load with a longer surface area.
  2. For a roof application, your load could span several roof trusses at once.
  3. Shorter base height for hatchways and transportation.
  4. Better mobility on slightly uneven surfaces.
  5. Lighter overall weight.
  6. Standard with four position locking caster on (4) outside casters.
  7. Slightly easier assembly.
  8. Easier height adjustment on “smaller models“.
  9. Uses a 10.5″ diameter tire.
  1. Easier reversing of direction.
  2. Higher lifting ability on tallest models.
  3. Less caster maintenance.
  4. Easier height adjustments on larger model sizes.
  5. Standard with four position locking pins on all (4) legs.
  6. Removable adapter plate allows for the use of our standard polyurethane casters.  An additional cost does apply for Polyurethane casters.
  7. Uses an 8″ & 10.5″ diameter tire.

Cons of this model Cons of this model
  1. More effort needed to reverse direction.
  2. More casters require maintenance.
  3. Polyurethane casters are not available.
  1. Heavier overall weight.
  2. Concentrated load on (4) points. Although there are (8) wheels total the footprint could be considered smaller.
  3. Taller main frame is harder to transport and maneuver in hatchways.
  4. Harder mobility on less even surfaces.
  5. Slightly harder assembly.
  6. Use of Polyurethane casters will lesson height in lifting ability.
