Shanghai guzuo HK series worm gear screw lifter is a heavy duty industrial linear lifting

device with compact vertical structure. Adopting high strength worm gear pair

and trapezoidal screw rod, this mechanical screw jack features stable self-locking, strong

bearing capacity and high structural rigidity.

   It can realize vertical lifting, pushing, tilting and synchronous height adjustment without

hydraulic system. with optimized shell structure and enhanced load design, HK lifter is

widely used for medium and heavy-duty low-frequency lifting industrial scenarios.

Main Features

• Powerful Self-locking Performance: Worm and worm wheel transmission provides excellent self-locking effect, ensuring load stays in position without slipping.

• Reinforced Trapezoidal Screw: Thickened high-strength trapezoidal screw improves compression resistance and wear resistance for heavy static support.

• Heavy-duty Cast Iron Housing: Integral cast iron shell enhances rigidity, shock resistance and structural stability under heavy load.

• Dual Driving Mode: Available for manual handwheel operation and electric motor drive to meet diverse working requirements.

• Synchronous Combination Function: Multiple HK lifters can be connected by connecting shafts to achieve multi-point synchronous lifting platform.

• Simple Maintenance: Reasonable internal structure design, easy lubrication and low daily maintenance cost.
