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

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

Heavy Load Worm Gear Screw Jacks combine a machine screw jack, motor and gear reducer into a single compact unit.  

Heavy Duty Worm Gear ACME Screw Jacks combine an acme screw jack, motor and gear reducer into a single compact unit.

The motor for screw jack can be servo motor,AC motor or DC motor. Its load capacity can be from 2.5ton to 120ton.

Worm Gear Screw jacks can be motorised by connecting electric motors through a B14 flange or a B5 bell housing with coupling. 

Trapezpodal Screw Jack (Machine Screw Jacks) Trapezpodal screw jack best for slower movement and low to moderate duty cycles .most machine screw jacks are inherently self-locking in the absence of vibration . A brake motor is usually not required to hold position on self locking jacks .Anti-backlash advices can be specified to limit backlash in reversing loads . Stainless steel , metric and motorized jack models are available with machine screws . Adaptable for wash down applications.

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 .
