Tower cranes, the most complete classification of tower cranes?

The tower crane is composed of three parts: metal structure, working mechanism and electrical system. Tower cranes are divided into fixed type and walking type, and now the fixed type is commonly used in construction. The fixed tower crane has three directions of movement, 1, is the lifting movement, that is, the use of the lifting mechanism to achieve the vertical movement of the items under the mountain.

2. It is the luffing movement, that is, the luffing mechanism is used to move in the diameter direction within the rotation range of the tower crane boom. 3. It is a rotary movement, that is, the use of a rotary mechanism and a rotary support to make the item move in a circular circle within the length of the arm. On the basis of the fixed tower crane, the walking tower crane has more movement of the tower crane itself on the rail.

According to whether the boom can move upward, it can be divided into boom and non-boom tower cranes.

The encyclopedia describes it this way:

A rotating crane with a boom mounted on the upper part of a towering tower. The working space is large, mainly used for the vertical and horizontal transportation of materials and the installation of building components in housing construction. It is composed of three parts: metal structure, working mechanism and electrical system.

The metal structure includes the tower body, boom and base, etc.

I'm a tower crane manufacturer, your problem is not good, simply put, the building is used to lift things.

Tower cranes are like that.

The tower crane is referred to as the tower crane. According to its different types, tower cranes are classified as follows. The following Zhongda Consulting will introduce it to you.

1) According to the structural type, the fixed tower crane: the tower body base frame is fixed on the foundation or structure through the connector, and the tower crane is used for lifting operations. Mobile Tower Crane:

A tower crane with a running device that can walk. According to the different running devices, Jingfeng can be divided into track type, tire type, and crawler type.

2) according to the rotary type on the slewing tower crane: the slewing bearing is arranged on the tower crane on the upper part of the tower. It can also be divided into the form of tower cap rotary type, tower top rotary type, upper rotary platform type, rotating column type bright beam, etc.

Slewing tower crane: a tower crane with a slewing bearing set at the bottom of the tower and the tower rotating relative to the underframe.

3) According to the erection method, it is divided into non-self-erecting tower cranes: tower cranes that rely on other lifting equipment to assemble and erect into a complete machine. Self-erection tower crane:

It is a tower crane that can realize the mutual conversion of transportation state and working state by relying on its own power unit and mechanism.

4) According to the luffing mode, the trolley luffing tower crane: the tower crane in which the hoisting trolley runs along the boom for luffing. Boom luffing tower crane:

A tower crane with a boom that performs a pitching movement for luffing. Knuckle boom tower crane: According to the needs of lifting operations, the boom can be bent tower crane.

It can have the performance of boom luffing and trolley luffing at the same time.

The tower crane is composed of three parts: the working mechanism, the metal structure, the power unit and the control system.

The working mechanism of the tower crane The working mechanism of the tower crane is usually composed of a lifting mechanism, a luffing mechanism, a slewing mechanism, a hydraulic jacking mechanism, and a traveling mechanism. The lifting mechanism realizes the vertical upper and lower movement shed cluster shooting of heavy objects; The luffing mechanism and the slewing mechanism realize the movement of the heavy object in two horizontal directions; The hydraulic jacking mechanism realizes the increase or decrease of the standard section, thereby raising or lowering the tower body, and the traveling mechanism realizes the arbitrary air movement of the heavy object within the reach of the tower crane.

The metal structure of the tower crane The metal structure of the tower crane is mainly composed of the main components such as the chassis, the tower body, the sleeve, the upper and lower supports, the boom, the balance arm, and the top of the tower. The metal structure is the skeleton of the tower crane, which bears the weight of the crane and various external loads during operation.

The power unit and control system power unit is the power source of the crane, and the power source of the tower crane is the motor that uses an external power supply. The control system includes control devices and safety devices.
