Grove rough terrains launched at Bauma

Manitowoc has unveiled two new rough terrain cranes, the Grove RT550E and RT770E. They were revealed in Munich, Germany, during the 15 to 21 April Bauma construction machinery exhibition.

Speaking on the new RT550E, Federico Lovera, Manitowoc EMEA product manager, said, “We have used the latest technology to make life easier for the operator and make lifts more efficient. The crane’s strength and size make it a very versatile machine that is perfectly suited to general construction and installation work throughout Europe and in markets around the world.”

The Grove RT550E has a 45 tonne capacity and a 39 metre five-section telescopic boom. Fitted with an 8 m fixed swingaway boom attachment, the reach is extended to 47 m. Described as compact, the crane is 12 m long, 2.55 m wide and weighs less than 29 tonnes. It means that the RT550E meets most European road regulations for heavy machinery, a company spokesperson said. The RT550E also has the Crane Control System, which automatically configures the boom length to suit specific loads and radii.

Also on show at Bauma was the Grove RT770E, which has a 65 tonne capacity and a 42 m five-section full-power main boom on a compact 8 x 3.33 m chassis. When configured with the 10.1 to 17.1 m bi-fold swingaway jib the main boom is extended to 59.1 m and the working radius can reach up to 44 m.

Power comes from a Cummins 6.7L diesel. The RT770E is expected to appeal to customers in the Middle East and Africa.

Paul Cutchall, rough terrain crane product manager at Manitowoc, said, “Normally, for customers to obtain this boom length on this size of rough terrain crane, they would need to install inserts, which would require an assist crane. We’re using a single cylinder technology that eliminates the need for an hydraulic hose reel. It lightens the boom and, in turn, the entire crane. It has given us considerable freedom and flexibility in the crane’s design and its performance.”
