GMK6350
features
Grove GMK cranes
incorporate a truly
independent suspension
system known as
MEGATRAK™ which
allows all wheels to remain
on the ground at all times
so that stresses and
weights are not continually
transferred between axles.
Controlled from the cab,
the suspension can be
raised or lowered (front-to-
back and side-to-side) or
automatically levelled for
highway travel.
While the operator is concentrating on the
lift, ECOS (Electronic Crane Operating
System) is busy monitoring and controlling
all of the principle crane functions and
providing exact telescoping status on its
fully graphic in cab display.
Monitoring the lifting condition of the crane at all times, EKS4 works
together with, but independently of the ECOS as a complete command
and control system, or separately as a load moment indicator.
Continually running fault analysis, the system advises service codes
which can be transmitted to any Grove service center,allowing fast
accurate investigation and recommendation.
The proven “U” shaped MEGAFORM™
boom design provides a natural cradling
position for boom sections which
eliminates stiffeners-thus reducing
weight and increasing capacity. Large
wear pads provide superior boom
alignment when telescoping and allows
an excellent transition of weights
between sections.
The unique TWIN-LOCK™ boom
pinning system automatically pins the
sections in position using two
horizontal large diameter pins, which
increases security. A single telescope
cylinder inside the boom reduces
weight which has been used
elsewhere to strengthen the machine.

51 ft. - 197 ft. (15.5 m - 60 m) five section, full power
MEGAFORM™boom with patented TWIN-LOCK™boom pinning
system. Maximum tip height: 207 ft. (63 m).
Boom Elevation
Single lift cylinder with safety valve provides boom angle from -
1.5° to +82°.
*Telescopic Swingaway Extension
36ft. - 62 ft. (11m-19 m) telescoping offsettable swingaway
extension. Offsettable at 5° and 30°.
Lattice Jib
Luffing Jib is a lattice design with lengths of 69 ft. -200 ft. (21 m -
61m) in sections of 26 ft. (8 m). The luffing jib converts to a fixed
offset lattice jib using an offset angle adapter and provides
lengths of 62 ft. - 194 ft. (19 m - 59 m) offsettable at 3° and 25°.
MEGALIFT™ Attachment-Main Boom
Consists of a mast, pendant lines, and hydraulic tensioning
winch to support the main boom during lifting operations. Load
charts available for main boom only as optional equipment.
Load Moment & Anti-Two Block System
Load moment and anti-two block system with audio/visual
warning and control lever lockout provides electronic display of
boom angle, length, radius, tip height, relative load moment,
maximum permissible load, load indication and warning of
impending two-block condition.
Cab
All aluminum construction cab is tiltable (approximately 20°) and
includes safety glass and adjustable operator’s seat with
hydraulic suspension. Other features include engine dependent
hot water heater, armrest integrated crane controls, and
ergonomically arranged instrumentation.

Tank capacity: 322 gal. (1220 L)
Control System
Full electronic control of all crane movements is accomplished
using electrical control levers with automatic reset to zero.
Controls are integrated with the LMI and engine management
system by CAN-BUS.
Hoist
Main and auxiliaryhoist are powered by axial piston variable
displacement motor with planetary gear and brake. “Thumb-
thumper” hoist drum rotation indicator alerts operator of hoist
movement.

Chassis
Box-type, torsion resistant frame is fabricated from high-strength
steel.
Outrigger System
Hydraulic two-stage outrigger beams are extended by a single
hydraulic cylinder and two cables. Outriggers can adjust to two
positions:
Fully extended (100%) - 27' 11" (8.5 m)
Partially extended (50%) - 19' 8" (6 m)
Four 29.5 in. x 32 in. (750 mm x 810 mm), self stowing, steel
outrigger pads provide rigid lifting base. Outrigger controls are
located on both sides of the carrier. An electronic level indicator
is located next to each outrigger control box.
