摘要： Front and rear pairs of crawler assemblies are provided for supporting concentric ring segments disposed forwardly under the boom and rearwardly under the counterweight so the crane can travel under load and swing through at least a partial horizontal arc. One and preferably both crawler assemblies are selectively and reversely powered to facilitate forward and reverse as well as turning movement during travel under loaded and unloaded conditions.

摘要： An energy absorbing backhitch for a lift crane including a hollow deformable element which is collapsed between squeeze rollers when the crane is over loaded a predetermined amount with respect to its rated capacity. The backhitch also includes a lift pin and means for sensing deflection of the lift pin and actuating visual and audio signals at predetermined load conditions.

摘要： The back hitch assembly for a lift crane includes hydraulic cylinders for raising the pivotally mounted gantry members and masts. Counterweight lift links are connected between the gantry and the counterweight and the back hitch cylinders may be used to mount and demount the counterweight and the boom hoist winch. The masts, gantry members and back hitch cylinders may be folded back over the bed of the crane for low profile transport or they may be demounted to further reduce weight.

摘要： A mobile crane with rotating bed, mast, gantry and gantry backhitch is arranged for disassembly and ease of transport without unreeving the boom hoist rigging by collapsing the backhitch, folding the gantry back onto the backhitch, pinning together the backhitch, gantry and boom hoist assembly -- which includes the boom hoist drum and motor, and releasing the gantry, backhitch and boom hoist assembly from the rotating bed. A bracket is fixed to the gantry to provide an anchoring point for the equalizer assembly normally secured to the boom.

摘要： A rotational drive assembly including a pair of pinion gears journalled on idler shafts disposed laterally on either side of a drive shaft and meshing with the teeth of a drive gear and a ring gear. The drive shaft is universally journalled for rotation and for permitting a limited range of movement of the drive gear toward and away from the ring gear to substantially equalize tooth contact between the drive gear and each of the pinion gears as the drive shaft is rotated. A slotted bearing may be provided to preclude excess lateral movement of the drive shaft.
摘要翻译： 一种旋转驱动组件，包括一对小齿轮，所述小齿轮轴颈安装在惰轮轴上，横向设置在驱动轴的任一侧并与驱动齿轮和齿圈的齿啮合。 驱动轴通常被旋转以便旋转，并且允许驱动齿轮朝向和远离齿圈的有限范围的移动，以在驱动轴旋转时基本上均衡驱动齿轮和每个小齿轮之间的齿接触。 可以提供开槽轴承以防止驱动轴的过度的横向运动。
