T Frame – Air/Pneumatic Tire Gantry Cranes

Aluminum T-Frame – Air/Pneumatic Tire Gantry Cranes

1,000, 2,000 3,000 & 4,000 lb. cap. AC “Air Caster” Gantry

EC&MW’s Air caster (AC model) gantry was inspired by the HVAC industries needs.  The eight/ten (depending upon model) pneumatic swivel casters makes it  ideal for moving loads over rooftops.  Applications include air handlers, compressors, electrical motors etc.  The lightweight aluminum construction makes it simple to break down for easy handling.

We have been manufacturing air caster portable gantries longer than any of our competition (by several years).  Along the way we learned a few things, such as adding the use of diagonal braces to all of our air caster model gantries.  The use of air caster on uneven terrain and softer ground surfaces will sometimes greatly increase the force required to push/pull the gantry crane.  Utilizing these braces adds superior strength to the columns and legs, so you can be rest assured of this gantries structural integrity. The few extra minutes that it takes to install the braces, we think is well worth benefits.

These braces attach to the receiver tubes as well as the I-beam, with the use of push pins and I beam clamps. This allows you to position your leg widths to fit your individual needs.  All of our portable gantry cranes use lanyards to attach our hitch and push pins, so misplacing parts is not a concern.

Uses:  The HVAC industry was our calling for this portable gantry crane.  To date nothing performs better.  Why: Greatly reducing the potential for roof damage. Our T Frame Air Caster Gantry Model wheels/tires span is longer than the industry standard A Frame design.  This increased span will enable, in some instances, the ability to load more than one roof truss at a time. Now this still does NOT lesson the total pounds per square inch.  That figure would be based on diameter, width and quantity of casters. More Uses: Replacing gate values in a field.  Other Industries: Agricultural, Aero Space, Museums and yes cemetery headstone replacement.  Side Note: We have been selling our gantries to the cemetery industry for almost 20 years. Teleshore UK Limited was and still is the original innovator and foremost authority of the use of aluminum gantries for cemetery maintenance and repair.

Note:  Before using gantry on any rooftops, always check with the buildings architect or engineer for roof load capabilities.  Additional shoring may be required.  Roof must be capable of supporting the load plus gantry, rigging and personnel.  EC&MW cannot and will not be responsible for any roof damages.  If an outside application is intended, the gantry should never be used on or in mud, sand, loose/pea gravel or any other soft foundations.  Gantry should only be used on reasonably firm packed level ground.
