Grove GMK7550Product Guide
Features• 450 t (550 USt) capacity
• 60 m (197 ft) five-section boom
• 25 m - 79 m (82 ft - 259 ft) lattice luffing jib
• 120 t (264,500 lb) counterweight with hydraulic installation/removal system
EKS 5 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.
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:• Areliablesuspensionsystem• Excellentjobsitemaneuverabilitywithall-wheelsteering• Commonalityamongalmostallmodels• Adrivelinethatremainsalignedatalltimes• Asteeringlinkagesystemthatisprotectedagainstdamage• Constanttirecontactforequaltirewear• Reducedmaintenance ECOS
ElectronicCraneOperatingSystem-ECOSenablescontrolof 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 sections in position using two horizontal pins.

16 m - 60 m (53 ft - 197 ft) five section, full power boomwithpatentedTWIN-LOCK™boompinningsystem. Maximum tip height: 63 m (207 ft).
Two lift cylinders with safety valves provide boomangles from -1.2° to +82°.

*Lattice jib
Luffing jib is a lattice design with lengths of 25 m - 79 m (82 ft -259 ft) in sections of 6,2 m (20 ft) and 12,2 m (40 ft). The luffing jib converts to a fixed offset lattice jib providing lengths of 12 m - 70 m (39 ft -230 ft) offsettable at 3° and 25°.
Graphic display load moment and anti-two block system with audio/visual warning and control lever lockout. These systems provide electronic display of boom angle, length, radius, tip height, relative load moment, maximum permissible load, load indication and warning of impending two-block condition.

Carrier
Special seven-axle carrier, welded torsion resistant frame is fabricated from high-strength steel.
Chassis
Hydraulic two-stage outrigger beams are extended by a single hydraulic cylinder and two cables. Outriggers can adjust to two positions:
Fully extended (100%) - 8,9 m (29.2 ft)Partially extended (50%) - 6,1 m (20 ft)
Four 810 mm x 810 mm (32 in x 32 in), selfstowing, steel outrigger pads provide rigid liftingbase. Outrigger controls are located on both sides ofthe carrier. Electronic level indicators with automatic levelling system. Outrigger pad load indication throughECOSandcarriercontrols.
