Servo Motorized Screw Jack

An electric screw jack is a mechanical device that converts rotary motion into linear motion using an electric motor. It is widely used to lift, lower, push, or pull heavy loads with high precision.

In a translating screw jack, the screw moves up and down through the housing. In a rotating screw jack, the screw spins in place, and a traveling nut moves along the screw to lift the load.

Yes. Models equipped with trapezoidal (acme) screws are inherently self-locking, meaning they will hold the load safely without back-driving. For high-efficiency ball screw models, an electric motor brake is required to hold the position.

Choose an Acme screw for low duty cycles, shock resistance, and self-locking requirements. Choose a Ball screw for high duty cycles, continuous operation, faster speeds, and energy efficiency.

Absolutely. Multiple jacks can be mechanically linked using connecting shafts, bevel gearboxes, and couplings to ensure perfectly synchronized lifting of large platforms. They can also be electronically synchronized using servo motors.
