HMR Supplies manufactures SPMTs

HMR Supplies engineers recently designed and manufactured a pair of SPMTs for a ship builder in the Great Lakes. The company needed to move large ship sections from one production facility to the next within the shipyard as the ship builder was using unconventional methods to move heavy sections between facilities. HMR Supplies provided the solution of a pair of SPMTs so the sections will move easily around the shipyard and maneuver into tight spaces safer and faster.

The two self-leveling SPMT units were designed with the following specifications:

  • 14’ wide X 16’ long (each unit)
  • Six knuckles
  • Stroke height of 18 inches
  • 20,000lb axle capacity
  • Gross load of 60 ton per unit
  • 70˚ turning
  • Two modes of steering – crab and articulating
  • 65 HP Kubuta diesel engine
  • RF wireless remoteEach SPMT unit the HMR Supplies engineering team designs is custom manufactured to meet the needs and purpose of the client project. Recent project analysis and workflow improvements allow the company to produce quality, effective products in a short amount of time.A familiar high profile SPMT project designed and manufactured by HMR Supplies is the 911-memorial tree mover, or straddle mover in New York City.  In addition to SPMTs, HMR Supplies is a leading manufacturer of dollies, and has sold the Holland Dollie® since 1981.
