35 ton Screw jack with motor for SWL35 tons Mechanical Worm Electric Screw Jack

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.

Screw jack is used in applications where linear motion is required. Lifting of any load, pushing or pulling of mechanical equipment, adjusting of tight clearances of mechanical parts can be done by screw jacks.

Screw jack/lift 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.

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

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

Screw jack is used in applications where linear motion is required. Lifting of any load, pushing or pulling of mechanical equipment, adjusting of tight clearances of mechanical parts can be done by screw jacks. Mechanical capacity of screw jacks is between 5kN and 2000kN, Jack screws can be used as linear motors, linear actuators, or mechanical lifts depending on type of motion. Working Principle of Screw Jacks Main components of screw jacks are: trapezoidal lifting screw, worm screw, worm gear and gear housing, Worm screw is rotated manually or by motor. Worm gear is rotated by worm screw. The lifting screw moves through the rotating worm gear. The linear motion speed of lifting screw depends on thread size and rotation ratio of worm gears.

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 .
