Boom Dollies

HMR Supplies has made a name for itself by engineering and manufacturing equipment for the heavy haul industry. The first Holland Dollie® was built in 1981. Since that time, HMR Supplies has continued to engineer and develop products that offer standard and custom solutions for heavy transport and on site moving. Currently, HMR manufactures everything from crane tag axles to dual lane transporters.The first boom dolly produced by HMR Supplies was for its sister company, CR Holland Crane Service, in the mid 2000’s. Since that time, HMR Supplies has found the boom dolly to be a natural fit for a standard product. HMR manufactures boom dollies in 2, 3, and 4 axle configurations to fit any make or model of crane.  We offer full dolly customization through tire selection, paint color, storage options and so much more. Check out our website for boom dolly options and specifications.

HMR Supplies adds new 45 Ton Holland Dollie® model

HMR Supplies has been manufacturing the industry-leading Holland Dollie® since 1981. That’s more than four decades of experience serving structural movers, heavy haulers, large construction, and large product manufacturers. We offer Holland dollies for rent or sale and will even customize them to meet your project requirements.  Holland dollies are manufactured in three standard configurations. Choose from the standard 40 Ton, the new 45 Ton, or the higher 55 Ton capacity to haul even more. The new 45 Ton capacity Holland Dollie® is in demand for its mid-range capacity in the structural moving industry.  

Many haulers use the modular capability of the dollies to reduce equipment footprint or add extra axles to meet road axle weight requirements. Each model offers a variety of options such as power steering to make structural moves run smoothly. 


Our ability to design and fabricate in house high-capacity, durable and efficient heavy material transport equipment is only part of what HMR Supplies does for its customers. What really sets us apart is the we combine existing products with employee ingenuity, expertise and full design-and-build capabilities to become our customers’ valued partners, helping them understand and overcome challenges. Many of our custom Holland dollies were engineered for specific uses and are now used for a variety of applications. 

SPMT’s

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.

40 Ton dolly

New Product – 40 ton Holland Dolly

New lighter weight 40 Ton Dollie

HMR Supplies redesigned the 40 Ton Dollie. This dolly is now manufactured with high strength T1 steel, shaving 300lbs off the dolly weight yet maintaining its ability to carry 40 Tons.  The engineers have also improved several dolly features, enabling smoother dolly operation.   

  • The top plate has been redesigned to allow the bolts to easily slide in precisely engineered holes. 
  • Pocketed bolts added on the castor plate. Only one wrench is needed to remove the bolts when switching to castor mode.  
  • Front shaft is hardened chrome plated. The housing has a bearing that reduces friction on the shaft during operation and eliminates shaft greasing. 
  • Rear plate bridge is stronger and taller. This redesign adds strength to the axle. 
  • Larger tool box. Offering the operator more room hold the castor bolts and pins & supplies.
