摘要： A mobile lift crane includes a carbody having moveable ground engaging members; a rotating bed rotatably connected to the carbody such that the rotating bed can swing with respect to the ground engaging members; a boom pivotally mounted on the rotating bed; a load hoist line trained over a pulley on the boom and wound on a load hoist drum connected to the rotating bed; and a boom hoist drum mounted in a frame. The boom hoist drum frame is connected to the rotating bed and a boom hoist line is wound on the boom hoist drum and connected to an upper equalizer and a lower equalizer, with the upper equalizer connected to the top of the boom by fixed length pendants, such that rotation of the boom hoist drum changes the amount of boom hoist line between the lower equalizer and the upper equalizer, thereby changing the angle between the rotating bed and the boom. The boom hoist drum frame, the lower equalizer and the upper equalizer each include cooperating attachment structures whereby the lower and upper equalizers can be detachably connected to the frame so that the boom hoist drum, the lower equalizer, the upper equalizer and the boom hoist line can be transported between job sites as a combined assembly.A method of dissembling and transporting the mobile lift crane involves a) disconnecting the fixed length pendants from between the boom top and the upper equalizer; b) disconnecting the lower equalizer from the rotating bed; c) disconnecting the boom hoist drum frame from the rotating bed; d) leaving the boom hoist line reeved between the lower equalizer and the upper equalizer and wound on the boom hoist drum; e) connecting the lower equalizer to the boom hoist drum frame; and f) transporting the boom hoist drum, boom hoist drum frame, lower equalizer, upper equalizer and boom hoist line together on a single transport trailer between one job site and another.

摘要： A counterweight block apparatus includes a pair of interconnecting counterweight blocks having top and bottom surfaces, the counterweight blocks forming a plane of interconnection along adjacent sides thereof; and a shear bar releasably secured between the adjacent sides of the interconnecting counterweight blocks, generally perpendicular to the plane of interconnection, to provide resistance to relative vertical movement of the interconnecting counterweight blocks along the plane of interconnection. In another aspect, each counterweight block includes in at least one side thereof an indentation from a top of the counterweight block to a depth more shallow than the thickness of the counterweight block, the indentation defining a lip for hand grabbing. An aperture may be formed through the rest of the thickness of the counterweigh block at each indentation, wherein a securing strap can be run through each aperture of a stacked plurality of counterweight blocks to secure them to each other.
