    摘要： A hoisting system includes an antenna that includes a main mast. A support is provided and the support may be coupled to a crane thereby facilitating the support to be elevated onto the antenna. The support engages the main mast such that the support is removably coupled to the antenna. A pulley is coupled to the support and a line is extended through the pulley. The line may have an object coupled thereto. The line is selectively urged through the pulley such that the line urges the object upwardly on the main mast.

    摘要： A come-along for pulling loads includes a rope winding mechanism that enables the rope to be wound and fed out smoothly. The rope winding mechanism includes a positioning hole that reduces the angle between the secured end of the rope and an axial tube about which the rope is wound. The come-along also includes a rope securing mechanism. The secured end of the rope has a seal head that fits through an installation hole and rests against the positioning hole. A helical slot around the axial tube enables the rope to wind evenly.

    摘要： A portable hoist or puller has two facing half shell members housing a chain sprocket rotatably affixed to a drive shaft supported for rotation by a pair of rollers. The first roller is slidably fixed for rotation with the drive shaft while the second is threaded to the shaft. The periphery of the threaded roller is serrated for engagement by a spring detent to inhibit its free rotation. Each roller has a hub portion extending outwardly of the housing to selectively receive a drive tool. A friction disc is disposed between each of the rollers and adjacent housing portion. To apply force to a load connected to the chain trained over the sprocket, the drive tool is coupled to the first roller and rotated causing the sprocket to feed the chain with the rollers pulled against the sprocket. If the drive tool released, the pull of the load tends to reversely rotate the shaft whereby the threaded arrangement causes the rollers to lock-up against the housing. To lower the load, the drive tool is coupled to the second roller and turned in the lowering direction. The shell members are retained together by a pair of upper bolts and single lower bolt. Attempts to overload the device cause elongation of the single lower bolt and resultant cocking of the housing shells so that the sides of the sprocket tend to dig into the housing to inhibit unsafe operation.

    摘要翻译： 便携式提升机或牵引机具有两个面对的半壳体构件，其容纳可旋转地固定到驱动轴的链轮，所述驱动轴被支撑以由一对辊旋转。 第一辊可滑动地固定以与驱动轴一起旋转，而第二辊被旋转到轴。 螺纹辊的周边是锯齿状的，用于通过弹簧制动器接合以阻止其自由旋转。 每个辊具有一个从外壳向外延伸的轮毂部分，以有选择地接收一个驱动工具。 摩擦盘设置在每个辊和相邻的壳体部分之间。 为了对连接在链轮上训练的链条的负载施加力，驱动工具联接到第一辊并且旋转，使得链轮沿着链轮拉动的链条进给链条。 如果驱动工具被释放，则负载的拉动倾向于使轴反向旋转，由此螺纹装置使得辊抵靠壳体锁定。 为了降低负载，驱动工具联接到第二辊并沿下降方向转动。 壳体通过一对上部螺栓和一个下部螺栓保持在一起。 尝试使装置过载导致单个下部螺栓的伸长并导致壳体壳体的翘起，使得链轮的侧面倾向于进入壳体以阻止不安全的操作。
