Upper works trailer

New Product – Holland Maxer

HOLLAND MAXERTM Trailer for Crawler Cranes
The Holland MaxerTM trailer is the solution to haul your crawlers faster and for less expense. Time is money and you will be down the road faster and easier with the Holland MaxerTM.

Features & Benefits

  • Four or five axle configurations
    • This creates the ability to meet tighter road restrictions
    • Use a three or four axle tractor to pull
  • Optional sixth and seventh axle configurations for extreme axle requirements
  • Caster axles with locks
    • Improved maneuverability
    • Increased tire life
  • Lift axles for
    • Maximum onsite maneuverability by raising axles to shorten the turning radius
    • Allows easier maneuvering for narrow driveways or access roads
    • Saving money, fuel economy, and tire wear by lifting unused axles while empty traveling down the road
  • Larger ground clearance than lowboys – this prevents trailers “getting hung up” while maneuvering
  • Stable suspension for high center of gravity load
  • Heavy duty 25,000 lbs. axles and suspension
  • High strength alloy chains and hooks for tying down – less chains means less time wasted securing and un-securing loads
  • Built in pull out access steps

Options

  • Optional power tower with limited tilting fifth wheel plate for rough sites requiring more clearance and oscillation
  • Optional manual tower with limited tilting fifth wheel plate to adjust for different truck heights and giving more clearance on rough sites
  • Air scales for axle weights
  • Storage boxes for remotes, rigging, and other crawler setup items
  • Storage locations for outrigger floats for self assembling crawlers

A Project for NASA

Our team has designed and manufactured custom solutions for several large-scale projects: the 911 Memorial tree planting system, the launch of a 215 ft long super yacht, and adding mobility to one of the largest mobile stages in North America. 

Our most recent project required HMR Supplies to mobilize an engine section for transport of NASA’s new rocket. Four 55T Holland Dollies and a Holland power unit were used to safely transport the engine. The engine section was loaded onto a barge at the Michoud Assembly Facility in New Orleans then traveled 1,240 miles by river to NASA’s Marshall Space Flight Center in Huntsville, Alabama. 


 

 

 

 

The size of this engine section is huge, check out the image provided by NASA. Read more about the NASA Project here.

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.

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.
