What's the difference between a quay crane and a crane?

1, different in nature: crane is a common name for crane, which is widely used in a series of heavy industrial products such as ships, equipment, machinery and molds. Crane is a kind of lifting and handling machinery widely used in ports, workshops, electric power, construction sites and other places.

2. Different features: the crane consists of two parts: the power device and the bracket. The name crane is the unified title of lifting machinery. Usually, cranes are mainly truck cranes, crawler cranes and tire cranes.

3. The principle is different: the crane is a kind of multi-function lifting machine that can vertically lift and horizontally carry heavy objects within a certain range. It belongs to material handling machinery, that is, the corresponding mechanisms of taking, transporting and unloading work alternately in a working cycle. The supporting part of the crane consists of a main rod and a rotating arm, and the rotating arm consists of a screw, a jack nut and a vertical rod. The rotating arm can rotate 360 degrees on the main rod, and the end of the arm is provided with a travel switch to prevent lifting accidents caused by operation errors or button failure.

Precautions:

1, tower crane operation should have enough workplace, boom boom boom ups and downs and no obstacles within the radius of gyration, night operation should have enough lighting equipment.

2, tower crane luffing indicator, torque limiter and various travel limit switches and other safety protection devices must be complete, sensitive and reliable, and shall not be arbitrarily adjusted and disassembled. It is forbidden to stop the machine with a limit device instead of an operating mechanism.

3. Before operation, you must fully understand the surrounding environment, roads, overhead wires, buildings and the weight and distribution of components.

4, tower crane operators and commanders must cooperate closely, commanders must be familiar with the mechanical properties of the command, the operator should strictly implement the commander's signal, such as the signal is unclear or wrong, the operator can refuse to perform. If the accident is caused by a command error, the commander should be responsible.
