Detailed explanation and classification of gates and hoists

The machinery used to open and close the gate, also known as gate operating equipment. The gate hoist is related to the normal operation of hydraulic structures. In addition to meeting the design requirements of general lifting appliances, the work safety and reliability and the flexibility and convenience of operation are of special significance.

The hoist can be classified according to different characteristics:

1. According to operating power can be divided into manpower, power, hydraulic.

2. Press power transmission can be divided into mechanical transmission and hydraulic transmission. Mechanical transmission is divided into belt drive, chain drive, gear drive and combination drive. Hydraulic transmission can be divided into hydraulic transmission and hydraulic transmission.

3 according to the installation status of the hoist can be divided into fixed and mobile. China often names hoists in this category.

4. According to the connection mode of gate and hoist, it can be divided into flexible, rigid and semi-rigid connections.

5. According to the characteristics of the gate is divided into plane gate hoist, curved gate hoist and herringbone gate operation machinery. It is also accustomed to use its integrated features to designate gate operating devices such as screw-type hoists, chain hoists, winch hoists, hydraulic hoists, trolley hoists, and gate hoists. Machine and so on.

The parameters of the hoist are: the opening and closing force, the traction or the applied pressure of the gate opening or falling, the opening and closing stroke, and the opening and closing speed. When selecting the type of hoist, the following factors are mainly considered: gate type, seal size and operating conditions, number of gates of the same type and number of gates, number of gate lifting lugs, lifting force, opening and closing stroke, and opening/closing speed , Hoist power conditions, location, space scale and other operational requirements.
