Project Description

LiftingMotion Cubic electric lifting screw jack load capacity from 0.25T 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.

  • Cubic screw jack type with compact and versatile cubic housing
  • 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.
