Versatile 20 Ton Capacity Mechanical Power Machine Screw Jacks lift and precisely position loads 20 tons. Upright or inverted, these precision jacks operate at full capacity whether the load is in tension or compression. Single lead screw jacks are self-locking under full lifting capacity. Double lead screw jacks offer increased travel speed.
1. Upright or inverted units with maximum static load capacity 20 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 65mm diameter, 12mm pitch (single start trapezoidal screw thread).
4. Available in 8:1 and 24:1 ratios.
5. Custom travel lengths from 25mm to 4000mm.
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.
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.
