HMR Supplies featured in Structural Mover Magazine
HMR Supplies and our sister company Atlas Enterprises are featured in the fall 2016 edition of the International Association of Structural Movers, Structural Moving Magazine. The article highlights a high profile structural move and engineering project. Atlas Enterprises, a structural moving company, moved the historic Egloff House over a 100 yr old bridge. HMR Supplies engineered and manufactured a temporary bridge to ensure the original bridge was not compromised by the weight of the home as it crossed.
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.
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.

Project – Stage Moving
HMR Supplies recently completed a large project in Wyoming. The challenge, to design a system to move a 50′ X 80′, 200,000 LB outdoor performance stage 200 yards. The customer requested a moving system be attached under the stage so that it could be move into an exact position between shows at the Cheyenne Frontier Days venue. Customer specifications indicated a 20 minute time requirement to move the stage into place and that the power to move the stage be provided by a two tractors. HMR Supplies designed a system using six custom dollies to move the stage.
Project engineering, specification drawings, programming, weight performance testing were completed at HMR Supplies facilities in Iowa.
To complete the project, HMR Supplies manufactured 6 dollies with a knuckle suspension. Steering and height were controlled by a hand held remote attached by umbilical cord and powered by a Holland Power Unit.
-The knuckle suspension on the dollies was 67.16 inches tall when collapsed and 85.66 inches tall when fully extended provided a lift of 18 inches. The knuckle suspension also provided a 135 degree turning capability to the stage.
-Each dolly weighed 10,000 LBS with a 56 inch wheel track, and eight 315/80R 22.4 20 ply tires.
-Spring applied brakes on the four outside modules for parking.
-The 100 hp. power unit featured a Fiat Power train diesel engine, a 30ft umbilical to the remote, 3 lifting zones, 2 steering zones, and 2 braking zones, and on board air compressor.
The project was installed and tested in June 2016. Testing onsite was successful, meeting customer requirements.
The project highlighted the work that we do best, customizing the Holland Dollie®product to meet the needs of the customer’s project.
