Winch hoist

The winch hoist produced by the company is divided into five series of models, such as QPQ, QPK, QPG, QPT (QM) and QHQ.

QPQ series winch type ordinary plane gate hoist is mainly used for opening and closing plane gate in water conservancy and hydropower projects. It is used to close the orifice of water discharge, water inlet and tail water, and to regulate power generation, flood discharge and drifting, and let go of boats. When the water pipeline or turbine needs to be overhauled, the inlet gate can be closed for overhaul. This series of hoists are powered by motors, and are divided into small, medium, large, and super-large capacity specifications, among which the medium and small capacity hoists can be equipped with reverse hand crank, which can be used to manually open and close the gate when the power is lost and the gate must be opened and closed urgently. According to the transmission mode, it can be divided into two structural types: open transmission and closed transmission.

QPK series winch type fast plane gate hoist is mainly used for the opening and closing of the fast gate of water conservancy and hydropower project inlet. i.e. when

The speed control system of the hydro-generator unit fails due to excessive load, and the gate is quickly closed within 2 minutes through automatic control or manual control before the occurrence of the flight or the rupture of the pressure pipeline, so as to achieve the purpose of protecting the safety of the unit and the plant. When the series of hoists open the gate, the motor is the power, and when the gate is closed quickly, the gate is held by the power of the motor to quickly lower, and the governor controls the gate lowering speed, and if necessary, the gate is loosened freely and quickly, and the gate is completely controlled by the governor at this time, so as to ensure the safety of the gate sill. It is suitable for the opening and closing of fast gates with opening and closing capacity of less than 2X2000KN. According to the transmission mode, it can be divided into opening and closing
