Overall Benefits

Weight Equalizing Coupler

Weight Transfer Machines Only
This unique and patented device incorporates the Unilok pivoted weight equalizing coupler. The weight floats vertically, slides horizontally and rotates on its platform giving optimum weight transfer and distribution to all four driving wheels, whether the machines is pulling or pushing, even on tight curves.


The Unilok Lift and Turn Platform is a device whereby the machine may be lifted on rail or road and rotated within its own length through 360 degrees. This feature is especially useful for machines operating in restricted areas and for going-on and off-rail on unprepared ground.

High Traction Rail Wheels

Specially developed polyurethane and rubber rail tyres provide the highest possible traction co-efficent in all conditions. Unilok tyres are tried and tested in all climates and environments, and have been developed in conjunction with Europe's leading tyre manufacturers.

Hydrostatic Transmission

Advanced automatic transmission on road and rail gives the unilok an infinitely variable speed range. Electronic sensing eliminates wheel spin and maximises overall efficiency.

Tracktronic Control

Engine and transmission performance are electronically controlled allowing the driver maximum flexibility in speed control and inching function.


Failsafe applied pressure released oil immersed disc brakes mounted on each wheel gearbox drive.
Hydrostatic braking through decelerating hydraulic system
Emergency and parking brake fitted on Deadman’s switch.
Separate wagon airbrake on high volume quick release system.

Remote Control

An integrated Remote Control system is available allowing economical and safe manoeuvering of wagons. All main driver functions are controlled allowing complete accuracy with the inching operation of railcar positioning.
