The heavy duty HSE high performance worm gear screw jacks are made for a load range of 500 kg (1,100 lb) to 100,000 kg (110 ton). The HSE series 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 improved.

Features and Benefits:

• 8 sizes with lifting capacities of 5 kN to 1000 kN
• Drive-motor speeds of up to 3000 rpm
• Self-locking trapezoidal machine screw
• Optional ball screw
• Separate lubrication circuits
• Machine screw with grease-lubrication and worm gears with oil-bath lubrication
