Center Mount Cranes

QMC center mount cranes are designed to maximize lifting capacity via crane placement, outrigger spreads, and counterweight to create a balanced package that accentuates capacity. Created to be a purebred lifting machine, these cranes utilize the proprietary QMC Lift Assist Control System to increase safety, operator confidence, and productivity. With lifting capacities ranging from 38,000 to 60,000 pounds, heavy duty double extending outriggers front and rear delay onset of tipping.

Highlights

  • Outriggers allow crane to develop maximum lift capacity over larger area, while increasing load capacities once tipping is reacherd.
  • Centralized crane mounting within outrigger footprint provides greatest stability in all quadrants with results in similar rear/side/front load charts for increase productivity.
  • Reduces necessity to adjust working radius when transitioning between quadrants.
  • Rotation quadrant sensing with Soft Stop automatically detects potential tipping when approaching quadrant with lesser rating and decelerates swing to a soft stop at quadrant boundary.
  • Allows lifting with two winches simultaneously as system sums both loads to prevent overload.
  • Provides for aerial rotation of loads from transport to final position enabling tall loads to enjoy easier rotation without dangerous center of gravity shifts and eliminates need to catch rotating load.
  • System fully integrated with state of the art hydraulic components to provide unparalleled crane control.
  • Use of mast mounted counterweight puts weight where it does the most good at opposite of load.
  • Payload allowance is reserved for rigging and tools.
