Electric Screw Jack 50 Ton Is Used in The Gantry Lifting Mechanism of Welding Equipment to Improve The Synchronous Self-Locking Performance

electric screw jack 50 ton is used in the gantry lifting mechanism of welding equipment to improve the synchronous self-locking performance
1. Upright or inverted units with maximum static load capacity 50 ton in tension or compression.
2. With higher ratios are inherently self-locking and will hold the loads without creep as long as the screw jack is not subject to vibration.
3. Lifting screw with 120mm diameter, 20mm pitch (single start trapezoidal screw thread).
4. Available in 10.667:1 and 32:1 ratios.
5. Custom travel lengths from 40mm to 7500mm. 
6. Translating lifting screws (travelling screw jacks), keyed lifting screws for anti-rotation (keyed screw jacks), and rotating lifting screws with traveling nut (travelling nut screw jacks) as the standard configurations.
7. Worm screw (input shaft) is rotated by a handwheel with handle (manually operated screw jack) or by a gear motor (electrically operated screw jack). 
8. Can be applied either individually use or in tandem or in multiple arrangements for exactly synchronized lifting system, linked by connecting shafts, bevel gears and couplings etc.

We use the best materials to guarantee the performance and lifetime of the screw jacks you purchased.

- Trapezoidal screw material - C45 steel. Customized stainless steel 304, 316.
- Worm shaft material - C45 steel, heat treatment. Customized stainless steel 304, 316.
- Worm gear material - high strength bronze.
- Housing material - ductile iron, available in stainless steel 304. 
- Traveling nut - high strength bronze.
- Safety nut - high strength bronze.

1. Note: The dark gray figures in the tables indicates operational restrictions due to thermal limits. Selection of screw jacks using these figures should only be carried out in consultation with our engineers. When your selection is made within the areas shaded dark gray, you will need to reduce duty cycle or choose the bigger size screw jack in order to allow effective heat dissipation.
