Grove AT Crane and Innovative Carrier Cab Unveiled at Intermat

According to Manitowoc Crane Group President Glen Tellock, the mentality of lifting needs continues to change, resulting in changes in product development to meet these needs. At Intermat, Manitowoc's new product introductions followed Tellock's sentiment by offering both innovation and technology advancements to enhance operator productivity.

Unveiled at the show, the 115-ton Grove GMK4115 features a brand new design, including a new carrier cab that will be introduced to the market in September. Focusing on functionality, ergonomics, and comfort, the cab features wide rear-view mirrors with curved shaping to increase visibility, more storage space inside the cab, and the latest ECOS control system. A radio with CD player comes as standard, as does temperature-adjustable air conditioning and heating.

The GMK4115 features a 170-foot, six-section boom with Grove's patented MEGAFORM shaping for greater rigidity and its TWIN-LOCK pinning system for a lighter design. A 33- to 56-foot bi-fold swingaway jib is available with two additional 16-foot inserts to reach a maximum tip height of 269 feet. The main boom has a telescoping time of less than 420 seconds.

The carrier's drive is 8x6x8 as standard and includes independent rear and crab steering. An optional 8x8x8 drive is also available. The carrier is powered by a 390-hp Mercedes Benz engine, while the Mercedes transmission provides 16 forward and two reverse gears, combined with a two-stage transfer case. On the superstructure, power comes from a four-stroke, direct fuel injection Mercedes-Benz OM 904 LA diesel engine, which offers a power rating of 147.5 hp. On the carrier, a new Michelin X-Crane AT tire is used. According to Michelin, this tire will increase tire life by 20% and provide a shorter breaking distance with its asymmetrical tread pattern.

Important to the European market, the GMK4115 can travel below 12 tonnes (13 U.S. tons) per axle when carrying 6.9 tons of counterweight, together with the bi-fold swingaway jib, a 17.6-ton hook block, and riding on 16.00 R25 tires. Up to 28.8 tons of counterweight can be carried. Deliveries of the GMK4115 will begin in August.
