Project Description

This Electric screw jack load capacity from 1 ton to 100 ton.  Motor and jack actuator assemblies can be installed in any position, such as handwheel, helical gear motor, stepper motor, servo motor, single-phase or three-phase ac motor, 12v /24v DC motor.

  • Translating(traveling screw) and rotating (traveling nut) configurations
  • Trapezoidal spindle (self-locking) and Ball Screw spindle (high efficiency) version
  • Design option: Standard, Anti-rotation, Anti-backlash or Safety nut
  • Standard and custom end fittings, mounting options, and drive shaft

You can trust us on high quality, on-time delivery, controlled costs and reduced risk.
