Product catalog summary
Specifications
The Hydraulic Crawler Crane Model 7120S has a maximum lifting capacity of 120 tons at a 5.0-meter radius and a maximum boom length of 61.0 meters. It is powered by a HINO P11C-VH engine with 271 kW at 1,850 min-1 and a maximum torque of 1,469 N·m at 1,400 min-1. The hydraulic system features four variable displacement piston pumps with a relief valve pressure of 31.9 MPa for the load hoist, boom hoist, and propel system.
General Dimensions
The crane has a carbody weight of 10.8 tons and a counterweight of 59.1 tons, resulting in an operating weight of 137 tons. The ground pressure is 107 kPa.
Boom and Jib Arrangements
Boom lengths range from 15.2 meters to 61.0 meters, with various combinations of boom base, tapered boom, and insert booms.
Working Ranges
Details on operational capabilities include maximum loads at different boom lengths and radii.
Supplemental Data
Operational guidelines include the necessity of boom backstops for all boom lengths and operation on a firm, level surface. The boom should be erected over the front of the crawlers.
Lifting Capacities
Lifting capacities vary based on boom lengths and load radii, with specific capacities depending on the number of parts of line used. Ratings are based on freely suspended loads, excluding factors like wind or ground conditions.
Transportation Plan
The transport weight of the crane is 37,800 kg for the base machine with boom base gantry and wire ropes.
Parts and Attachments
Lists available parts and attachments, including counterweights and carbody weights.
