Electric Motors

Power Jacks can supply electric motors for all applications whether AC or DC motors are required.

We can also supply AC or DC motors with brakes; they are spring applied electrically released units, which provide the fail safe operating characteristics such that on interruption, or failure of power supply, brake will engage and arrest the load.

The gearboxes available are available as motorised units as standard, however the gearbox unit itself can be supplied. The most popular types of gearboxes are Helical Worm Gearboxes, In-line Helical and Parallel Shaft, other types are available on request.


Couplings & Drive Shafts

Full range of coupling and drive shafts so you can build complete jacking systems.

We have a range of flexible jaw couplings with elastomeric elements and steel geared couplings for high torque transmission.

Drive shafts are available in a self-supporting design that does not require plummer block bearing supports and in the traditional solid shaft design.
