features

The exclusive GroveMEGATRAKTM independentsuspension system allows allwheels to be on the ground atall times; now with top steeringon rear axles.

The newsuperstructure cabstows to the rear andswings hydraulically tothe right side of thecrane for operation.Stationary heating andA/C are standard.

The rear outrigger box can be removed and replaced withan 8th axle for travel situations demanding additional axleweight distribution, (shown below with optional aluminumwheels).

The operator’s cab onthe GMK7550 uses thenew EKS5 LMI systemand ECOS (ElectronicCrane OperatingSystem) with acombined dual screendisplay mounted on atiltable swing arm.

The TWIN-LOCK boompinning system-a Grovepatented design - runsinside a five sectionMEGAFORM boom.

The Mercedes OM 502LA, 8 cylinder carrierengine provides 563(420 kW) horsepower.

The superstructure ispowered by aMercedes OM906 LA 6cylinder 255horsepower (190 kW)engine.

A sturdy 240 ft. (73 m)luffing jib on 179 ft.(54,6 m) of main boomprovides up to 410 ft.(125 m) max tip ht withapproximately 295 ft.(90 m) of workingradius.
