Motor Driven Screw Jacks Classic Design

Motor driven screw jacks (also known as a electric motor screw jack, a motor operated screw jack, a motor powered screw jack, or a motor driven worm screw jack) is used in many fields where it is necessary to lift different loads, such as automated production lines for sheet metal machinery, packaging, textiles, plastics, renewable energy and more. Motor driven machine screw jacks with trapezoidal screws have precisely positioning and self-locking feature for no creeping down without brake mechanism or locking systems. Important Note: ball screw jacks are self-lowering without self-locking. Brake motors are required to stopping and precise positioning the load for motorized ball screw jacks. If the motor frequency will be varied to provide a soft start, an inverter duty brake motor may be required.
Screw jacks with motor driven can be used as a single unit motor driven screw jacks or in multiple combinations as perfectly syncronized motor driven screw jacks lifting systems which links two or more screw jacks by drive shafts, couplings and right angle gear boxes. Motor types of motor driven screw jacks: three phase induction motor, single phase induction motor, geared motor, stepper motor, servomotor, worm gear motor reducer, air motor or hydraulic motor, dc motor and dc geared motor. All standard motors are 3-phase, 220-380 VAC, 50hz, 1450 rpm. Single phase motors are 220 VAC, 50hz, 1450 rpm. Load capacities of motor driven screw jacks: 1 ton, 2.5 ton, 5 ton, 10 ton, 15 ton, 20 ton, 25 ton, 35 ton, 50 ton, 100 ton capacity models.
Motor Driven Screw Jacks Mounting Types
1. Standard foot mounting types: screw jacks, jaw type couplings, foot mounted electric motors (IEC B3).
2. Standard vertical flange mounting types: screw jacks with motor adapters, vertical flange mounted electric motors (IEC B5, IEC B14, small NEMA C-face motor flanges).
3. Customize vertical flange mounting types: screw jacks with customize motor adapters, jaw type couplings, vertical flange mounted electric motors (IEC B5, IEC B14, small NEMA C-face motor flanges).

Motor Driven Screw Jack Motor Flange Mounting Directions
M1 = Left side shaft, Right side motor flange
M2 = Right side motor flange
M3 = Right side shaft, Left side motor flange
M4 = Left side motor flange
Note: Motor flange input types, if need to purchase the motor from us, your purchase orders must be marked. Otherwise, we only sale screw jack with motor flange.
