Manitowoc’s new Grove GMK6300L six-axle all terrain crane has a 300t maximum lifting capacity and offers more power when lifting at tall heights, the manufacturer has said. The seven-section telescopic boom ranges from 15.6-80m, with a maximum tip height of 83m.
“We’ve designed it for impressive picks on its main boom, without the need to rig the jib,” said Michael Preikschas, Manitowoc’s senior regional product manager for all terrain cranes in EMEA. “For example, with the boom extended to 74.8m it will lift 14.3t, and with the full boom of 80m it lifts 12t.”
Additional equipment includes a 12-21m bi-fold swingaway jib, which can be combined with an 8m fixed lattice extension for a total boom length of 108m. With the boom fully extended, and the 29m swingaway jib and fixed extension, the CMK6300L lifts 1.1t to 50m in the 20-40° angle range with 35.5t counterweight. An optional 2.3m heavy duty jib has a 38t capacity.
New features on the GMK6300L include a fully automatic transmission and a choice of five outrigger positions. It also has a newly designed cab for the carrier, which seats three. Styled similarly to Grove’s four- and five-axle all terrain cranes, the GMK6300L has been adapted to fit the wider carrier of the six-axle crane. This cab also has more ergonomic positioning of instruments for better driving, Manitowoc said, and improved visibility, heating, air conditioning, aerodynamics and noise reduction.
Dimensions for the crane show a boom overhang on the front of 1.73m over the 15.4m carrier. Axle spacings are favorable, with 3.2m between the first pair of axles and 2.5m between the second.
