RCT has devised an agnostic speed limiting solution for underground trucks following a recent approach from a mine in Western Australia.

The mine recently approached RCT for this for three of its newly acquired underground trucks and its operators at its mine site.

The trucks were equipped with seven gears from factory settings, and the client wanted to be able to control the speed of the trucks while underground to ensure safety of operators and the mine itself.

“In order to speed up trucking tonnes-kilometres the client wanted to speed limit the trucks underground but have the operators to still be able to utilise all of the gears at a higher speed while on the surface,” RCT’s Account Manager, Scott Phillips, said.

The state-of-the-art safety solution is fully programable with four speed settings available to suit individual needs to various situations and speeds. The tamper-resistant design also conveniently interfaces directly into a machine throttle circuit.

In addition, a Geo-Fencing kit was implemented on site to further control the trucks speeds in different locations and a proportional retarder control system to make sure the truck maintains a constant speed no matter the gradient it is manoeuvring on.

With speeding being widely recognised as a major contributor to light vehicle accidents in mine sites around the globe, this solution is well sought after in the mining industry, according to RCT. In addition to reducing incidents, it also helps to lower fuel consumption.

The client has been so impressed with the speed limiting solution that it has already ordered three more to be installed on more trucks operating on site, RCT says.

As with all RCT’s solutions, the Speed Limiter is agnostic and is suitable for all makes and models.
