Over Head Track Equipment - OHTE

This model variant is used to maintain the Overhead Track Equipment (hence the designation “OHTE”). This involves all the power supply infrastructure found on electrified rail networks. South Africa has roughly 22,000 km of rail network, of which some 40% is electrified.

The OHTE vehicle features a flat deck fitted with a Mobile Elevating Work Platform (“MEWP” or “cherry picker”). This can also act as a crane for lifting poles into position alongside the track. The cherry picker can be controlled either from within the basket itself, or from the deck. The vehicle seats three in the main cab.

✓ The vehicle is based on the UD80 8-ton chassis. The main components are as follows:

✓ Flat deck

✓ Combination Mobile Elevating Work Platform (“MEWP”) / 3 ton.metre crane mounted to deck

✓ Large vertical storage locker just behind the main cab

✓ A pantograph mounted just behind the main cab on top of the vertical locker. This is used to provide a means of earthing the vehicle, as well as a means of gauging the height and lateral location of overhead conductors.

The crane base can be side-shifted across the truck to ensure maximum stability, with tilt safety switches and an emergency cut-off in place for additional safety.
