摘要： A mobile lift crane includes a carbody, a rotating bed, a boom, a moveable counterweight unit, at least one linear actuation device and at least one arm pivotally connected at a first end to the rotating bed and at a second end to the linear actuation device. The arm and linear actuation device are connected between the rotating bed and the counterweight unit such that extension and retraction of the linear actuation device changes the position of the counterweight unit. In one method of operation, the counterweight is never supported by the ground during crane pick, move and set operations other than indirectly by the ground engaging members on the carbody. One embodiment includes a counterweight movement structure having a rectangular rack with at least first and third pinion gears engaged with teeth on one side and second and fourth pinion gears engaged with teeth on the opposing side.

摘要： A mobile lift crane includes a carbody; a rotating bed; a boom; a moveable counterweight unit; at least one linear actuation device; and at least one arm pivotally connected at a first end to the rotating bed and at a second end to the linear actuation device. The arm and linear actuation device are connected between the rotating bed and the counterweight unit such that extension and retraction of the linear actuation device changes the position of the counterweight unit compared to the rotating bed. In one method of operation, the counterweight is never supported by the ground during crane pick, move and set operations other than indirectly by the ground engaging members on the carbody. The linear actuation device can include at least one rack and pinion assembly or hydraulic cylinder. In another embodiment, the crane comprises a counterweight movement structure including a rack and pinion assembly having a housing and a rack, the rack having a rectangular cross section with first and second sides opposite one another and third and fourth sides opposite one another, and having teeth on the first side and second sides, and at least first and third pinion gears engaged with the teeth on the first side of the rack and second and fourth pinion gears engaged with the teeth on the second side of the rack, and wherein each pinion gear is driven by a separate hydraulic motor, and wherein the motor driving the first pinion gear is mounted on the housing adjacent an opposite side of the rack from the motor driving the third pinion gear, and wherein the motor driving the second pinion gear is mounted on the housing adjacent an opposite side of the rack from the motor driving the fourth pinion gear. In another embodiment the crane includes a counterweight support structure attached to the counterweight unit. The counterweight support structure includes at least two ground engaging members that can provide support to the counterweight in the event of a sudden release of the load. The support structure comprises a telescoping structure connected to and between the ground engaging members such that the distance between the ground engaging members can be adjusted between a first and second position.

摘要： A drum tensioning method is provided for operating a crane having a continuously reeved load hoist line, with a first end of the load hoist line connected to a first drum and a second end of the load hoist line connected to a second drum, with the load hoist line reeved through boom sheaves and a hook block. The method includes the steps of applying a hold-back force to the second drum; applying a winding force to the first drum greater than the hold back force on the second drum; and applying the winding and hold back forces while limiting movement of the hook block, thereby spooling the load hoist line from the second drum through the boom sheaves and hook block to the first drum while maintaining tension in the load hoist line such that the load hoist line is wound under more tension on the first drum than it had previously been wound on the second drum.
