EKS 
e EKS  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.
MEGATRAK™
e MEGATRAK™ suspension system is the best o road
driveline available on the market today. e system’s versatility and
performance allows the GMKL to operate as a true all-terrain
crane. e 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 benets of the MEGATRAK™ system are:

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.
TWINLOCK™
Boom pinning mechanism automatically pins the
