The high performance worm gear screw jacks of the series HSE are available for a load range of 5 to 1000 kN. The series 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.
