Trailer Mount Cranes

QMC trailer mount cranes are designed for delivery and placement of your heaviest and bulkiest loads. They provide a sensible alternative to hauling and setting nondivisible loads too heavy for truck mounted cranes. An 80,000 pound vehicle weight allowance fully maximizes your payload capability. The trailer mount crane replaces two vehicles–crane and trailer–with one.


  • Allows closest unencumbered access to jobsite over rear to capitalize on highest ratings of crane and increases over rear work area definition for greater productivity.
  • Crane mounting over rear outriggers minimizes structural flex, providing greatest rigidity and stable operating platform.
  • Places crane in a central location between transported load and final set, while preserving payload envelope by placing crane at extreme end of unit.
  • Offers best use of overall unit weight to enhance stability when lifting, minimizes tipping and maximizes lifting, and increase structural zone and operator confidence.
  • Reduces necessity to adjust working radius when transitioning from rear to side quadrants.
  • Available as a flat or drop deck to meet payload size requirements.
  • Air ride suspension is standard to protect equipment and cargo from road shocks.


  • Wide spread tandem axles with lift capability are available to allow for greater loads on tandem axle group and to reduce wear and tear while operating unloaded.
  • Triple rear axles available to allow for best payload placement.
