The connecting pull plate 40 is a pull plate that is installed on the thrust mechanism 41 and is connected with the superlift counterweight pull plate 50; And connect pull plate 40, wherein, crane turntable is the turning center of crane, thrust mechanism 41 can change the distance of superlift counterweight 51 and crane turntable by stretching, thereby adjust the moment of superlift counterweight 51 to crane.

The specific connection method of connecting the drawing plate 40 and the super lifting counterweight drawing plate 50 is as follows: the staff stands on the standing platform and connects the connecting drawing plate 40 and the super lifting counterweight drawing plate 50 coaxially. Simple, and not limited by the site, when the connecting pull plate 40 and the superlift counterweight pull plate 50 are connected, the thrust mechanism 41 can be connected with the superlift counterweight 51 according to the work needs and the superlift counterweight 51 can be moved and lifted. Upgrade action.

It should be noted that the tail of the thrust mechanism 41 is suspended in the air and the position of the tie plate connection 60 is relatively high. Usually, the staff often need to be hoisted by a crane when performing the operation of the tie plate connection, and then lie on the thrust mechanism 41 to pull the plate The operation of the connection, such a tie plate connection method has certain safety hazards for the staff, and due to the difficulty of the working environment, the quality of the tie plate connection is not high. The utility model provides a crane. The crane is provided with a standing platform 101 below the connecting part 60 of the pull plate, which provides a horizontally arranged foothold for the staff, and the staff can stand on the standing platform 101 stably and safely to complete the connection and pull.
