Based on above-mentioned technical scheme, can remove whole setting to the position of treating the equipment of hoisting before lifting by crane, utilize actuating lever adjustment to hang the position of cylinder support for treating the equipment of hoisting, the rope end couple of second cotton rope is at the same height and be close to the lug with equipment lug position, later promotes the actuating lever adjustment and hangs cylinder support position to make the rope end couple lug of second cotton rope, accomplish the couple action, this kind of mode is applied to the condition that can't carry out the couple operation near equipment lug department more.

Furthermore, a plurality of walking wheels are installed at the bottom of the support.

Based on the technical scheme, the whole equipment has stronger mobility and can move freely.

Furthermore, the mounting plate is fixed to the bottom of the support, the fixing rod is fixedly connected to the mounting plate, one supporting column penetrates through the fixing rod to be connected with the supporting disc, and the supporting column can move up and down relative to the fixing rod.

Preferably, the fixing rod is provided with a threaded hole, and the supporting column is provided with an external thread matched with the threaded hole.

To the further explanation of the utility model: the utility model discloses a lever drive ratio principle reaches the purpose of hoist and mount object. The first stage is between manual drive handle dish, the winding cylinder, and the winding cylinder diameter is less than manual drive handle dish diameter, and the power arm is greater than the resistance arm promptly to play the effect of first stage province's power. The second stage is between the drum part with larger diameter of the hoisting drum and the drum part with smaller diameter of the hoisting drum, and the resistance arm of the drum part with smaller diameter of the hoisting drum is smaller than the power arm of the drum part with larger diameter of the hoisting drum, thereby playing the role of second stage power saving.

The utility model has the advantages that: the hoisting machine can be replaced (for medium and small motors), and even under special conditions, the hoisting function can be realized due to power failure of a power grid, and in addition, the cost reduction function (without power utilization) can be realized.
