Product Usage

rack and pinion mechanical jack is a safe, practical and convenient lifting, its greatest advantage is to overcome the hydraulic jack hydraulic leak Er Shi as top heavy drop from the shortcomings, it maintain a long stay in the support position, so particularly suitable for upgrading of the heavy long position after the occasion demands. Some frequently used in the following situations:
1. Mechanical assembly and repair of vehicles from the top of the machine when used, vehicles and equipment used to from the top of prefabricated construction, etc..
2. Railway sector maintenance when used in railway tracks from the top.
3. Mines, tunnels, bridges, concrete poured in the pit prop support.
Four. Loading and unloading will be prostrate, lifting a lower position of the items before the pre-top.

The common worm screw elevator is mainly composed of worm gear reducer and lifting screw. Its deceleration component is worm drive, and the worm gear is driven by the worm to realize deceleration.
The worm gear and screw lifter can be used for each set or structure, can precisely control and adjust the height of lifting or promotion according to certain operating procedures, can be immediately promoted by motor or other driving force, and can also be manually pulled. It has different structural methods and assembly line methods, and the elevation can be customized according to customer requirements
