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.
The MEGATRAK™ suspension system is the best off road driveline
available on the market today. The system’s versatility and performance
allows the GMK5275 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
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.
Boom pinning mechanism
automatically pins the
sections in position using two
CraneSTAR is an exclusive and innovative crane asset
