    摘要： The present invention pertains to a wear pad assembly for adjusting a position of a wear pad in a telescopic boom of a work machine, comprising a threaded boss, a threaded bolt configured for threaded engagement with the threaded boss and a wear pad connectable to the threaded bolt. The wear pad assembly further comprises locking means configured to lock the threaded boss and the threaded bolt in a first engagement position and at least a further engagement position. The present invention further pertains to a method of adjusting such a wear pad assembly, the wear pad assembly being mounted to a first telescopic boom segment such that the wear pad provides a sliding surface for a second telescopic boom segment, the method comprising the steps of unlocking the threaded bolt by disassembling at least a part of the locking means, rotating the threaded bolt from the first engagement position into the further engagement position, and locking the threaded bolt in the further engagement position by reassembling the disassembled locking means when the threaded bolt is in the further engagement position.

    摘要： A crowd assembly (30) for a power shovel (10) includes a saddle block (34) adapted for pivotal connection to the shovel boom (24). A tubular dipper handle (32) is slideably supported by the saddle block. A hydraulic actuator (50) has a cylinder (52) and a piston rod (54) that is outwardly extendable from one end of the cylinder. One of the cylinder or the piston rod is fixed to the dipper handle and the other one is attached to the saddle block. The cylinder and the piston rod are within the tubular dipper handle which is able to slide longitudinally over the cylinder. A guide bushing (70) extends around the one end of the cylinder and engages an interior surface of the dipper handle. The guide bushing thereby supports that end of the cylinder and inhibits hydraulic actuator from deflecting within the dipper handle when the piston rod is extended from the cylinder.

    摘要： A telescoping lift arm assembly has an outer lift arm tube that is formed with a cross section configuration that has spaced side walls, and outwardly extending flange guide panels at the lower portions of the side walls. An inner lift arm tube is generally bell-shaped and fits into the outer lift arm tube and has outwardly flared flanges that are parallel to the flange guide panels of the outer lift arm tube. The inner lift arm tube is held in place with a cross support plate that is supported to the side walls of the outer lift arm tube, to hold the inner lift arm tube in place. There are linear bearings between the mating outwardly flared flanges and panels, as well as between the support plate and mating lower surfaces of the inner lift arm tube. Fasteners are provided to adjustably hold the support plate secured to the outer lift arm tube.

    摘要： Disclosed herein is a miniature, portable, self-contained power machine for handling materials, comprising, a rigid frame providing the base structure for all components of said machine, a means of electrical power supply for said machine, means for regulating the motion of said machine, two endless roller chains forming a traction system and serving as the means to move said machine over various types of terrain, means for readily receiving and rigidly securing a variety of miniature, hydraulically powered material handling implements to said machine, and a central hydraulic system which is powered by said power supply means and which supplies power to said attachable material handling implements. The machine has a diversity of applications in numerous industries. The machine accepts any of a variety of attachable implements through an assembly socket and a torque arm socket, and then links the implement to the central hydraulic system with hydraulic hoses leading to a hydraulic power manifold. Two of these implements include a telescoping boom and bucket assembly and an improved forward reach and higher lift capacity bucket assembly. A hydraulically powered dumping bed attachment may be bolted to the rigid frame of the machine and further modified to result in a hydraulically powered dumping bed and hopper attachment.
