A crane is a mechanical equipment used for hoisting and carrying heavy objects. It is widely used in ports, construction sites, warehouses and other places. Its main components and structure are a precision engineering design. The main components and structure of the industrial crane will be introduced one by one below.
Industrial crane mainly includes hoisting mechanism, operating mechanism, luffing mechanism, slewing mechanism and metal structure. The hoisting mechanism is the basic working mechanism of the crane. It is mostly composed of a suspension system and a winch, and some also use a hydraulic system to lift and lower heavy objects.
The operating mechanism is used to transport heavy objects longitudinally and horizontally or adjust the working position of the crane. It is generally composed of a motor, reducer, brake and wheel.
The luffing mechanism is only equipped on jib-type cranes. The amplitude decreases when the jib is raised and increases when it is lowered. It is divided into two types: balanced luffing and unbalanced luffing.
The slewing mechanism is used to rotate the boom and is composed of a driving device and a slewing support device.
The metal structure is the skeleton of the crane. The main load-bearing parts such as bridges, booms and gantry can be box structures, truss structures, or web structures, and some can use shaped steel as supporting beams.
How many parts does a crane consist of?
A Industrial crane is a mechanical equipment used for lifting, transporting and loading and unloading. It generally consists of the following parts:
1. Support system: including machine tools, wheels, legs and foundations, etc., to support and stabilize the crane.
2. Hoisting machinery structure: including main frame, hoisting machinery structure (lifting arm, lifting mechanism, turntable and motor, etc.).
3. Drive system: including motion system and control system. The motion system usually consists of electric motors, hydraulic systems, gears, transmission mechanisms, braking devices, etc. The control system is used to control the movement of the crane.
4. Operation console: including crane operating panel, display screen and controller, etc., used to control and monitor the movement status of the crane.
5. Spreaders: including hooks, clamps, etc., used to connect objects, hoist and carry goods.
The above systems are the main parts of the crane, and different types of cranes may contain different specific components.
