The screw jack can be a self-locking trapezoidal screw jack or a high-precision ball screw jack. The motor can be a high-precision servo motor, stepping motor, helical gear motor, worm gear motor, three-phase asynchronous motor and 12v, 24v, 48v motors and DC gear motors, etc.
If it is a high-precision ball screw jack, a brake motor or an external locking device is required to maintain the position.
