HMR Supplies – 911 memorial

Remote Controlled Load Transport System 

HMR Supplies completes several large projects every year. A few years ago, our team designed a custom remote controlled tree setting system for planting tress at the 911 memorial. In 2014, we received the patent for this piece of equipment.    

Remote controlled load transport system

HMR Supplies designed the Straddle Mover (a remote controlled load transport system) to meet the special needs of planting trees on the 9/11 Memorial plaza. It was important for the equipment to be able to carry the tree in the center of all the axles, be capable of traversing sideways and able to negotiate openings on the surface of the plaza. There are also up to 8 stories underneath the plaza for access, equipment and a museum requiring low ground pressure and a wider tire base. 

When you see the Straddle Mover up close, on the 9/11 Memorial webcam or on YouTube, it is an impressive site. The knuckle suspension is able to lift and lower the frame and load up to 20 inches. The block and cable system is capable of lowering the load below ground level, and 135 degrees of steering allows the Straddle Mover negotiate the tight quarters on the plaza. A single operator and a remote control operate the straddle mover. 

Although the Straddle Mover was originally designed for moving trees, it can also be used for a variety of applications.

HMR Supplies specializes in designing and manufacturing equipment for moving large, heavy material in the most cost-effective fashion. And for the energy industry, you can add “very long items” to the list as well. Our equipment safely and efficiently transports pipe, vessels and storage containers. Our solutions include moving 300-foot steel tendons in ways that prevent bowing or bending. We’ve designed self-propelled modular Transporters(SPMTs) that safely move these football-field long materials from a fabricating facility to storage areas and onto transport vehicles.
