The GRT655 RT crane has a 55-ton capacity with a 114.3-foot, four-section, full-power boom. The boom is greaseless. Bottom wear pads support the boom sections and consist of a continuous, flexible sheet of oil-impregnated pad material and are arranged in a segmented style that provides greater support than previous boom designs.
Polymer outrigger pads enable operators to stow the pads more easily, saving time and effort on the job site. Smart-length-sensing extension cylinders monitor the crane’s outrigger beam positions. The sensor technology in each cylinder enables operators to get an accurate, repeatable measurement during outrigger deployment.
The GRT655 offers equal line pull on both the main and auxiliary hoist, allowing for a maximum first layer pull of 16,658 pounds. A Cummins QSB 6.7 L diesel engine delivers 164 bhp. GVW is 79,376 pounds.
Crane Control System (CCS) comes standard and improves operator familiarity for lifting companies since the same ergonomic controls and intuitive displays are used across many of Manitowoc’s cranes. It also improves parts and maintenance needs, with components working across several crane ranges. Other CCS features include an ECO function that has been designed to reduce fuel consumption and engine noise, as well as a Working Range Limiter that benefits operators by delivering real-time lift parameters that are easily read onscreen.
