What are the components of a crane
Cranes are the key machinery and equipment for loading, unloading, handling and relocation, and they can be operated frequently and frequently. The working characteristic of the crane is to do intermittent fitness exercises, that is, the relative distribution of the postures such as loading, transporting, and unloading in a working cycle system is to change the work. The application of cranes is becoming more and more common, and it has become the key to the development of the industry. Equipment.
1. Crane lifting structure
The transmission system is like this: the motor drives the high-speed shaft of the reducer according to the high-speed shaft coupling, passes through the reducer and expands the torque, and the low-speed shaft drives the wire rope drum according to the low-speed shaft coupling. The drawn galvanized steel wire rope is connected with the pick-and-place machinery and equipment through the guiding movable pulley and the labor-saving lifting pulley. Because the motor can be positive and rotating, the wire rope drum can wind in or release the lifting rope to lift the goods.
2, the structure of the crane in operation
According to its characteristics, it can be divided into two categories: working and non-working. The working work structure cooperates with other assignments to move goods. The non-working work plan is generally only used to adjust the working direction of the crane. According to the structure type, it can be divided into track work and trackless work. The distribution of track work depends on whether there are drive machines and equipment in the work, and there are self-propelled and self-propelled and The points of walking. There are two types of drive methods for the work plan: the collective drive and the respective drive. Qiji drives are only suitable for small-span cranes or work plans for hoisting cars.
3, the rotation distribution of the crane
Rotating support point machinery and equipment are divided into two types: column type and rotating type. The column slewing support is divided into a fixed column type and a rotating column type. The floating raft crane mostly adopts the fixed column type, and the gantry crane also adopts the rotating column type before. Rotary slewing supports are divided into roller bearing clamp sleeve type, supporting point roller type and roller bearing type.
