JACTON offers multiple units screw jacks in a lift system that can be used individually or in multiple arrangements. The screw jack lifting system comprehensive lifting and positioning design solutions for a wide variety of industries. But must pay more attention to the application of multiple units screw jacks in a lift system.

First, synchronization lifting: when the multiple units screw jacks in a lift system is driven by motor or geared motor, they should be connected to ensure synchronization, the coupling shaft is good in universal transmission shaft, and the rigid transmission shaft uses flexible coupling to adjust the installation error. In addition, the servo motor is used to guarantee synchronization, PLC and frequency converter to ensure synchronization. 

Second, lifting speed: if travel speed less than 10mm/s is suitable, when speed greater than 10mm/s guides are needed, otherwise the screw jack system will be vibration. If rotating screw jack systems, the top traveling nut should have a fixed bearing, otherwise the screw will sway. 

Third, guide systems: the guiding mechanism should consider the force balance in the direction of X-Y, and a variety of selection methods, the form of straight line sliding rail in the pipe, like the train wheel in the form of rolling in the rail, and the form of the V type wheel in the angle steel rolling. 

Four, limit switches safety control:limit switches can not be used to control movement, it is only to protect the screw jack does not exceed the stroke.
