Screw jacks can be used singly or in multiple configurations connected to each other with bevel gears, transmission shafts, and c45 steel couplings.

These products find their perfect combination in a "four corner" H-configuration or U-configuration, where the four screw jacks connected among them by means of shafts, spider jaw couplings and bevel gears, allow the transmission of the movement with a perfect synchronism, even if the load is not equally distributed.

You can even design complete lifting systems and construct and synchronise them using our accessories. Typical accessories are: Single universal joint and Double universal joint, Cardan shafts, Connection shafts, Pedestal bearings, Motor cones for motor attachment, AC standard motors, Torsionally flexible couplings, Bellows and spiral springs,

Expandable universal joints are double joints with plain bearings or needle roller bearings plus a sliding splined centre section to allow adjustment between shaft ends in worm screw jack systems. Length adjustment should be made statically without torque load. Running angles can be up to 45deg. C per joint. A range of standard models is available

Rigid clamp couplings "couple"—i.e., clamp onto and connect—two shafts aligned with each other in screw jack systems. By joining the two shafts, these mechanical components enable the transfer of rotary motion from one rotating shaft (the driving shaft) to the other (the driven shaft).

With readily available accessories, connecting shafts can be coupled to the worm gear actuators, gear boxes can provide for the rotation and connection for a multiple actuators arrangement.

Manual Screw Jack with handwheel with handle is very popular for all kinds of applications. For example: In case of power failure, screw jacks can be moved manually via a handwheel. To do this, one input shaft shall be available on the screw jack for the connection of the handwheel. If a brake motor is used, the brake shall be un-clamped firstly,

Worm gear screw jacks can be used separately or in groups connected with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. They also can be driven by different motors: electrical, with either 3 phase AC induction motors or 12v 24v DC motors as well as hydraulic or pneumatic motors.

To achieve synchronous lifting, you can link multiple screw jacks together. Drive system: single phase AC motor, three-phase AC motor, DC 12 / 24V motor, no air or hydraulic pressure source.

A brake motor is usually NOT required to hold position on self-locking screw jacks. However, a brake is recommended for all applications involving vibration since there is dynamic loading on the threads which may overcome friction. Ball Screw Jacks are self-lowering. A brake of sufficient torque is required to hold the load with a ball screw jack.

The working principle of YVP series variable speed induction motor is changing the frequency of power supply to achieve the purpose of motor speed regulation. The YVP Series Inverter Motor is widely use in electric screw jack actuators, to adjust the lifting speed by frequency inverter.
