The invention discloses a double-layer four-group eight-pulley lifting hook which comprises a first-stage support, two second-stage supports and pulley blocks, the two second-stage supports are installed at the two ends of the first-stage support, and the second-stage supports are rotationally connected with the first-stage support. The two ends of each secondary support are each provided with a pulley block, and each pulley block is provided with two pulleys side by side. And each pulley block is rotatably connected with the secondary support. The second-stage support is connected with the first-stage support through a pin shaft seat, and the second-stage support is mounted on the pin shaft seat and is rotatably connected with the pin shaft seat. The structure is suitable for hoisting of a large-tonnage tower crane. And the multi-magnification change of the hoisting weight can be realized, and the hoisting flexibility is provided.
本发明公开了一种双层四组八滑轮吊钩,包括一级支座、二级支座、滑轮组,二级支座为两个,安装在一级支座两端,二级支座与一级支座可转动连接。每个二级支座两端各安装一个滑轮组,每个滑轮组上并排安装有两个滑轮。每个滑轮组与二级支座可转动连接。二级支座与一级支座通过销轴座连接,二级支座安装在销轴座上,并与销轴座可转动连接。上述结构适应于大吨位的塔机起吊。可以实现起吊重量多倍率的变化,提供起吊的灵活性。
