Project Description
This machine screw jack load capacity from 1 ton to 120 ton. Low Cost and safe load!
- Best Materials: Ductile iron housings, ball thrust bearings provide rugged reliability, high strength bronze worm gear
- Version: upright or inverted, traveling nut or screw translating
- Option: Anti-rotation, anti-backlash, safety nut, left-hand screw threads
- This machine jack uses an acme screw, typically used to move heavy loads in low-duty-cycle setups and low-speed applications.
- Connect a motor or hand-crank shaft to the screw jack shaft to lift, hold, position, and level loads.
You can trust us on high quality, on-time delivery, controlled costs and reduced risk.

LMS Jack Order Guide
LMS Model NO— screw jack type – top end type – worm shaft type – gear ratio – travel length – necessories(limit swith/bellow)
- If the mechanical lifting machine jack is loaded in compression. It may be necessary to select a jack with a load greater than the nominal. This is due to the relationship of the diameter to the maximum spindle length. You can consult our engineering for analysis of the applied force.
- As the duty cycles are intermittent, there is an inverse relationship in relation to the maximum duty cycle of the actuators and the load being moved. Please consult our application engineers for assistance in determining the most suitable machine jack.
- The input RPM must not exceed the value in the table.
- Never exceed the static and dynamic capacity of the jack.
- Never exceed the power listed in our specification tables.
- If the maximum power recommendation is exceeded, reduce the speed or use a larger capacity jack.
