Screw hoist, cast iron gate, reservoir, river course and hydropower station equipment with complete models

Screw hoist, also known as screw hoist, is a machine that uses a threaded rod to connect to the gate leaf directly or through a guide slider or connecting rod, and the screw moves up and down to open and close the gate. It is reported that with the widespread development of water conservancy and hydropower projects, hoists and gates are widely used in river dams in reservoir irrigation areas, hydropower stations and other engineering projects. The installation and commissioning technology and knowledge of use and maintenance of screw hoists should also be vigorously promoted.

Since screw hoists are now widely used, here, the editor will introduce to you what should be paid attention to during the operation of screw hoists

First, check the power supply and backup power supply. The screw hoist requires three-phase power to work. The first thing to ensure before starting work is that the voltage is stable and the three-phase power is sufficient. Check whether the opening and closing operating status on the power indicator is consistent with the power indicator.

Secondly, during the operation of the screw hoist, it is necessary to ensure the coordination between the hoist and the gate. When the gate is in the open state, it is prohibited to move the braking equipment and fixing screws.

When the screw hoist exceeds a certain height, the screws in the lubricating parts must be tightened to prevent malfunctions. If a malfunction occurs midway, stop working immediately and check after the power is turned off.
