PRODUCT SPECIFICATIONS

SWL Series

Swl series worm screw lift is a kind of basic lifting component, which can lift, lower, propel, turn and other functions through the worm drive screw.
Screw jack can be widely used in machinery, metallurgy, construction, chemical, medical, cultural and health, and other industries. Can according to a certain procedure to accurately control the adjustment of the height of ascension or propulsion, can be directly driven by motor or other power, can also be manually. This series of worm screw lift can be self-locking, with the bearing capacity ranging from 2.5 tons to 120 tons, the maximum input speed of 1500 r/min, and the max lifting speed of 2.7 m/min.

Features:

1. Suitable for heavy load, low speed and low frequency;

2. Main components: precision trapezoid screw pair and high precision worm gear pair.

3. Compact design, small volume, light weight, wide drive sources, low noise, easy operation, convenient
maintenance.

4. The trapezoid screw has self-locking function, it can hold up load without braking device when screw stops traveling.

5. The lifting height can be adjusted according to customer requirements.

6. Widely applied in industries such as machinery, metellurgy, construction and hydraulic equipment.

7. Top End: top plate, clevis end, threaded end, plain end, forked head and rod end.
