The working characteristics of the Overhead Crane And Hoist

The working characteristics of the Overhead Crane And Hoist:

One.  Overhead Crane And Hoist usually has a large bearing metal structures and more complex, can complete a lifting movement, one or several levels. For example, the bridge crane can complete three movements: lifting, trolley running and trolley running; In the process of operation, the movement of several different directions is often operated at the same time, and the technical difficulty is great.

Two. The loads are varied and the loads are variable. Some weight hundreds of tons of and even thousands of tons, some objects up to dozens of meters, the shape is irregular, and grain, hot melt state, inflammable and explosive dangerous goods, etc., the lifting process complex and dangerous.

Three. Most Overhead Crane And Hoist need to operate within a larger range, some with rails and wheels (such as Overhead Crane And Hoist, bridge cranes, etc.), To furnish a tire or crawler walking on the ground (e.g., truck crane, crawler cranes, etc.), And the need to run on a steel wire rope, etc.), such as aerial ropeway and suspension cable crane, activity space is larger, in the event of accident, the face of the impact is bigger also.

Four. Some Overhead Crane And Hoist , such as elevators , lifting platforms and so on , are required to carry personnel directly on the guide rails , platforms or steel wire ropes , and their reliability directly affects personal safety .

Five. Exposed, moving parts, and often in direct contact with hoisting operators (such as hoisting hooks, wire ropes, etc.), there are many potential accidental risk factors.

Six. Complex working environment. From construction sites to large iron and steel conglomerates to modern ports, railway hubs and tourist resorts, cranes operate. The workplace is often exposed to high temperature, high pressure, flammable and explosive, transmission lines, strong magnetism and other risk factors, which threaten the equipment and operators.

Seven. It often takes a lot of people to work together to complete an assignment. Therefore, commanding, bundling, driving and other operators are required to cooperate with skilled, coordinated movements and mutual care, and the operator should have the ability to deal with the emergency situation on the spot. There is a great difficulty in the close cooperation among the many workers.
