Manitowoc, a leading manufacturer of lifting equipment for the construction market, has selected the technology of fully automatic transmission specialist Allison Transmission for its new Grove GMK6300L. Launched last week at Bauma, the six-axle all-terrain crane with an extended boom offers increased power, maneuverability and driver comfort.
The GMK6300L is designed to lift 300 tons and features a main boom that can extend 80 meters. For further operating distance a 37-meter boom extension is also available. The lifting capacity of 12 tons at 80 meters is designed to simplify tasks such as tower crane erection, placing air conditioning units and elevator equipment on high rise buildings or chimney work. The crane is powered by a Mercedes OM 502 LA engine matched to the six-speed Allison fully automatic transmission 4500 SP. Power for the crane boom comes from a separate Mercedes OM 926 LA engine.
“The GMK 6300L is the only one in its class that has a fully automatic transmission offering the best driveability on site,” said Michael Preikschas, Grove’s senior regional product manager for all-terrain cranes in EMEA. “The Allison 4500 SP is a strong, reliable and cost effective drivetrain solution. Its capabilities are proven even in the most arduous conditions and the electronic controls allow it to adapt to its surroundings and provide self-diagnostics for easier maintenance. An integral retarder offers enhanced braking on hills and greater safety for the operator when moving a heavy vehicle.”
Headquartered in Indianapolis, Allison Transmission is a global provider of commercial duty automatic transmissions and hybrid propulsion systems. Allison products are specified by more than 250 of the world‘s leading vehicle manufacturers and are used in many market sectors including bus, refuse, fire, construction, distribution, military and specialty applications.
