New Grove GMK7550 All Terrain Crane for Sale

The Grove flagship the GMK7550 offers a 550-ton maximum capacity on a seven-axle carrier. The 7550 has a stowing crane cab for highway travel. The optional MegaWingLift attachment increases capacity throughout the working radius.

The GMK7550, offers a 550 USt maximum capacity on a seven-axle carrier with a stowing crane cab for highway travel. The optional MegaWingLift attachment increases capacity throughout the working radius.

MEGATRAK™: The MEGATRAK™ suspension system is the best off-road driveline available on the market today. The system’s versatility and performance allows the GMK7550 to operate as a true all-terrain crane. The MEGATRAK™ independent suspension and all-wheel steer system allows wheels to remain on the ground at all times so stresses and weight are not continually transferred between axles. MEGATRAK™ provides true ground clearance where others just raise the chassis.

Other benefits of the MEGATRAK™ system are:

  • A reliable suspension system
  • Excellent job site maneuverability with all-wheel steering
  • Commonality among almost all models
  • A driveline that remains aligned at all times
  • A steering linkage system that is protected against damage
  • Constant tire contact for equal tire wear
  • Reduced maintenance

TWIN-LOCK™: Boom pinning mechanism automatically pins the sections in position using two horizontal pins.

ECOS and EKS 5: Electronic Crane Operating System - ECOS enables control of the entire crane’s principle operations. Simple programming eases lift planning and a supply of essential information allows full concentration on the lift itself.

The EKS 5 monitors the lifting conditions of the crane at all times and provides a full graphic display, rear lighting, graphic of boom telescoping percentage, and load charts.
