Screw jacks are transmission products (machine screws or ball screws) that make rotary motion using gearbox assemblies (worm gears or bevel gears) and motors. They can be used to push, pull, tension, unlock, tilt, rotate, pull, raise or lower loads ranging from a few kilos to several thousand tons. The key components of screw jacks are trapezoidal lifting screw, worm screw, worm gear and gear housing. Worm screw is rotated manually (manual screw jack) or by a motor (electric screw jack). The screw jack working principle: Worm screw rotate the worm gear; the rotating worm gear move the lifting screw up and down in linear motion way. If input a small rotation force on worm screw, it can amplify force from lifting screw shaft. This mechanical advantage property is good for raising and lowering maintenance platforms, opening and closing air dampers, oven doors, sluice gates, adjusting tooling machine beds.

Screw jacks are a combination of a screw with a gearbox. There are three types of configurations that can be adapted to different requirements:

Translating screw design: The screw moves when the gearbox input shaft (worm shaft end) is activated. It includes a rounded screw protection tube on the back.
Anti-rotating keyed screw design: The screw engages, as in configuration translating screw design but with the difference that the screw with milled keyway, or the back protective tube is square section.
Rotating screw design: The screw does not move with the driving of the worm shaft, it only turns; it is the corresponding travel nut that moves along the screw.

Hand Wheel Manual Screw Jack 1 Ton to 20 Ton
Hand wheels in a variety of diameters. They are recommended for self-locking jacks and actuators and can be mounted directly to the jack input shaft. Since hand wheels are are mounted directly onto jacks and actuators and specified as part of the complete jack part number. Their specific selection is dependent on input torque requirements.
A hand wheel is a convenient solution for manually operating a jack when using machine screw jacks in intermittent positioning applications. Hand wheels are available in a range of diameters from 5 to 16 inches and can be adapted for use on jacks up to the 20 tons capacity model.
NOTE: Hand wheels do not include a brake and therefore are not for use with ball screw jacks. When using hand wheels with a jack that can back drive (12:1 and lower) an additional locking mechanism may be required to prevent "creep".

Electric Motorized Screw Jack 1 Ton to 100 Ton
Screw jacks can be connected directly to an electric motor creating a compact linear drive. Standard 3 phase motors are most common. For lower powers DC motors can be used, or servo motors can achieve high performance.
Electric Screw Jack can also be called motorized screw jack, it includes a worm gear screw jack and an electric motor.The screw jack can be self-locking acme screw jack or high precision ball screw jack.The motor can be high precision servo motor,stepper motor,helical gear motor, worm gear motor, 3-phase asynchronous motor and 12v,24v,48v do motor and dc gear motor etc.
Electric Screw jack lift Function: The Electric screw jack actuator is a basis jack-up part, accomplish the functions such as lifting, drop, push and inverting through worm gear drives screw, because it is driven by electric motor, it has higher efficiency than manual screw jack.

Screw Jack Lifting System 0.1 Ton to 1000 Ton
Worm Gear Screw Jack systems are ruggedly designed and produced in standard models with load handling capacities from 1 ton to 100 tons. They may be used individually or in multiple arrangements. There are no "standard" travel lengths and all Worm Gear Screw Jack systems are built to specification. The jack housings are made of ductile iron and proportioned to support the rated capacity of the unit.
Screw Jack System is usually used for lifting heavy duty load or lifting platform. Screw Jack System mainly includes screw jack, bevel gearbox, electric motor, connecting rod coupling, gear reducer.
