The series MERKUR is available for a load range of 0.25 t to 25 t. The cubical design and the all-round handling facilitate an easy alignment of the drives during installation. MERKUR lifting screw jacks are operated wherever loads have to be positioned under moderate duty cycles and little dynamic.

Features and processing


• 9 different sizes
• Lifting capacities  of 2.5 to 500 kN
• Drive-motor speeds of up to 1,500 rpm
• Grease-lubricated version
• All-round handling allows for an easy alignment
• Self-locking rolled trapezoidal screw
• Grease  lubricated worm gears in two ratios steps (normal “N” and slow “L”)
• identically constructed to European manufacturers of worm gear screw jacks with cubical design
