Screw jack

  • Lifting screw jack, rotating screw
  • Lifting capacities of 5 to 250 kN
  • Ingoing speed up to 3000 min-1

NEFF spindle lifting element (type MH/JH-R) with standing rotating spindle for loads up to 250 kN. The NEFF spindle lifting elements (type MH/JH-R) are provided with precisely machined worm wheels, which have separate lubrication with respect to the spindle. As a result, higher input speeds are permissible. The cubic design and machined housing on all sides simplifies actuator alignment during installation.
