Screw jack

  • Lifting screw jack, axial screw
  • Anti rotation by sliding block in tube
  • Lifting capacities of 5 to 200 kN

NEFF screw jack (type M/J-VK) with axial lifting screw or rotating screw for lifting capacities from 2,5 up to 500 kN. The NEFF M/J-VK screw jack is used wherever loads have to be positioned under moderate duty cycles and little dynamic. The cubical design and the all-round handling facilitate an easy alignment of the drives during installation.
