The high performance worm gear screw jacks HSE has been developed specifically for the dynamic use at medium and high lifting speeds and an increased duty cycle.

The housing made of spheroidal graphite iron with the cast-on cooling fins is designed in such a way that high heat dissipation to the surrounding area is ensured.

Features and processing

• 8 different sizes
• Lifting capacities from 5 to 1000 kN / 500kg up to 100t
• Input speeds up to 3000 min-1
• Self-locking trapezoidal screw
• Separate lubrication circuits: Tr screw with grease-lubrication and worm gears with oil lubrication
• Worm gear pairs in two ratio steps (normal „N“ and slow „L“)
• Worm-drive shaft case-hardened and ground
• Patented gearing construction with different heat zones for medium and high lifting speeds
• Possible usage according to directive 2014/34/EU (ATEX)
