NEFF MH/JH-R
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.

Mobile lifting platform with NEFF screw jacks and Faro bearings

Lifting of a system with lifting elements of NEFF lifting jacks. A complete solution including gearboxes, drive shafts and a controlled drive. Featured with optimal guidance componants of Faro. When the work platform is raised, the guidance components ensure that the platform remains stable. This makes it possible to work safely on the platform.

The installation is moved with crane wheels and Stober drives.The added value of ATB Automation was proven again while helping with the fine-tuning of the lifting system at delivery.
