Mechanical Structure Characteristics Of Jib Crane

     Lifting machinery is an intermittent work, lifting objects or lifting and within the limits of the movement of objects. Hoisting machinery is an indispensable equipment in modern industrial production, which is widely used in lifting, transporting, loading and unloading of various materials and transporting personnel. The national hoisting machinery has about 250,000 units. The country has more than 400 cranes production plant, an annual output of more than 30,000 units, and the annual rate of 10% increase.Jib Crane

     Lifting machinery according to its function and structure characteristics, can be divided into three categories: the first Category: Light and small lifting equipment, its characteristics are light, compact, simple, operation range projection to point, line mainly; the second category: cranes, which are characterized by the ability to achieve vertical lifting and horizontal movement in space with heavy weights hanging on lifting hooks or other pickup devices. The third category: lifts, which are characterized by heavy weights or pickup devices that can only be lowered along the rails. These three types of hoisting machinery are also made up of many different structures and work-use machines.Jib Crane

     In addition, cranes have a variety of classification methods. Sorted by pickup device and use, there are hook cranes, grab cranes, electromagnetic cranes, stacking cranes, container cranes and rescue cranes, etc. according to the classification of migration, there are fixed cranes, operating cranes, climbing cranes, cranes, etc. according to the driving mode, there are support cranes, cranes, etc. According to the use of the classification, there are workshop cranes, warehouse cranes, construction cranes, port cranes, ship cranes and so on.Jib Crane

     Equipment factors include: suspension failure, such as hook, grab, wire rope, nets and other damage caused by heavy objects fall. The failure of the control system of the lifting equipment or the failure of the safety device causes an accident, such as the failure of the braking device to cause heavy impact and clamping.Jib Crane 

     The strength of the component is not enough, such as the dumping of the tower crane, because the overturning moment of the tower is more than the stable moment. Electrical damage caused an electric shock accident. The reason for the derailment accident of Bridge Crane is that the loosening of fasteners is caused by the phenomenon of gnawing rail.Jib Crane
