Our trapezoidal screw jacks(also named acme screw jack) JWM series is suitable for low speed and low frequency.

Two-set linkage screw jack system can be "L", I and T configuration.  It usually consists bevel gearbox, screw jack, electric motor, gear reducer, hand wheel, pillow block bearing, jaw coupling, line shafting.

Four-set linkage screw jack system can be  I and T configuration, transmission efficiency can be 85% .

Eight-set linkage screw jack system can be 2H and H configuration, transmission efficiency 80%.

Worm Screw Jacks HK series belong to trapezoidal screw jacks. They are available in a useful range up to a capacity of 100T and are competitively priced.

Electric screw jack actuators is a basis jack-up part, accomplish the functions such as lifting, drop, push and inverting through worm gear drives screw.

ACME worm screw jack is very popular for lifting. Both translating and rotating design are available.

Trapezoidal Screw Elevator is widely applied in industries, such as machinery, metallurgy, construction, and hydraulic equipment, and has many functions, such as lifting and pushing and turning with the help of accessories or adjusting height and position.

Electric machine screw jack,also called motorized machine screw jack, is very popular for lifting.

Rotating Screw Jack is common used and has the advantage of low cost and heavy load.

Usually , a jack system does not continue to be operated so frequently . So people do not care about a loss in electricity expenses by selecting a large motor , and tend to select a motor with a larger capacity than calculated value , considering that it would be better than an insufficient one .

Rotating Nut Design ( Traveling Nut ) These jacks have a fixed length lifting screw that rotates . Loads are attached to a flanged “traveling” nut that translates up and down the length of the rotating screw . This type of jack is ideal for applications that cannot accommodate a screw protection tube or that require a flush mount .
