Description

A jib crane

technical field

The utility model relates to the technical field of cranes, in particular to a boom type crane.

Background technique

The cantilever crane mainly uses the edge (pitch) of the jib to rotate around the vertical axis to cooperate with the lifting and lowering of the goods. It is flexible in use and meets the requirements of loading and unloading. Fixed jib cranes are directly installed on the piers of the wharf or yard, and can only work in situ. Some of the booms can only be pitched but not rotated, and some can be pitched and rotated. Mobile boom cranes can run along the track or on the ground, mainly for truck cranes, tire cranes, crawler cranes and portal cranes. Among them, tire cranes and portal cranes are widely used in ports. Mobile cranes such as automobiles, tires, and crawler are also called automatic cranes. The floating overweight crane is a cantilever crane installed on a special flat-bottomed ship, which is widely used in the loading and unloading of sea and river port gates and port construction.

Most of the existing jib cranes cannot adjust the angle of the hook when suspending objects, and cannot meet the needs of users, and when taking out the hanging object from the hook, it needs to be taken out manually, which is time-consuming and labor-intensive, and affects the the efficiency of the device.
