Project Description

This bevel gear jack load capacity from 4KN to 200KN. Spiral bevel gear mechanism is used, so it can achieve fast travel speeds up to 6M/minute for nearly continuous operation. 

  • Bevel gear with integral acme or ball screw
  • High speed, high efficiency, high duty circle
  • Can be used individually or in multiple arrangements
  • Version: screw translating, nut rotating and keyed (anti-rotation)
  • Compared with the worm gear screw jack, the bevel jack system’s long-duty cycle feature and multiple configurations make it a diverse product that suits a variety of applications.

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