[0002] With the gradual development of cranes towards large tonnage, various jibs are usually required as auxiliary supports on the main arm of the crane. The commonly used crane arm support device is based on the mast and is completed by pulling the additional wire rope. The installation of the device is inconvenient and the scope of application is small. The mast is installed on the boom through the door frame and is fixedly connected with the first boom. The stability of the hoisting of the whole vehicle increases the safety hazards in the use process and reduces the efficiency of the crane in the working process

The invention relates to a super-lifting device for a crane. The super-lifting device comprises masts and telescopic arms. The lower portions of the telescopic arms are connected with sliding blocks, wherein acute angles are formed between the telescopic arms and the sliding blocks. The sliding blocks are inserted in a frame. Sliding way baffles are installed on the outer sides of the frame. Bolts A are installed on the outer sides of the sliding way baffles. Connecting rods are fixed to the upper portions of the inner sides of the frame. The lower portions of the inner sides of the frame are provided with grooves. An insertion opening located in the frame is formed in the part, in contact with the frame, of the end an insertion rod. The frame is fixed to a first lifting arm, and lifting arm edges are arranged on the two sides of the first lifting arm. The sliding way baffles are installed on the outer sides of the frame so that the sliding blocks can be put on the frame along the gaps between the sliding way baffles and the frame, after the sliding blocks completely enter the sliding way baffles, the bolts A are tightly screwed, and then the masts together with the sliding blocks are fixed. Installation is convenient, demounting is easy, and after installation, the structure is firm, and safety and reliability are achieved. Generally, the super-lifting device has the beneficial effects that installation is convenient, the application range is wide, and stability is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of cranes, and in particular relates to a super-lifting device and a using method of a crane. Background technique [0002] As the crane gradually develops towards the direction of large tonnage, the main arm of the crane usually needs various auxiliary arms as auxiliary supports. The commonly used crane arm support device is based on the mast and is completed by pulling the additional wire rope. This kind of crane super-lift The installation of the device is inconvenient and the scope of application is small. The mast is installed on the boom through the door frame and is fixedly connected with the first boom. The stability of the hoisting of the whole vehicle increases the safety hazards in the use process and reduces the efficiency of the crane in the working process. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a c...
