Movement of large equipment in an underground mine is one of the most significant hazards that miners are exposed to during each shift. SOTO has developed a Tow Hitch in consultation with mine operators to allow for the controlled and reliable transport of heavy equipment within a mine. This device provides superior features to other commercially available towing devices and is rated to 50T.


The following video explains in brief the finer points of the why, how and what the Tow Hitch is primarily designed to help with, although it can be adapted to tow many other underground equipment to a maximum of 50T.

Show Me the Detail

The Tow Hitch gives the mine operator confidence and control by providing a safely rated connection which allows maximum turning, tilt and deviation capabilities ensuring efficient transportation of shuttle cars and other heavy equipment in the underground environment.

The Tow Hitch is simple to use. The rotating tongue, together with the ability to compensate for variation in floor surfaces ensures stability of the vehicles at all times. The hitch has been rated and tested to shunt 50T loads.

The Tow Hitch results in improved control of heavy tow loads and ease of manoeuvring the shuttle cars and other long loads while shunting. This means it is possible to have one man operation when towing shuttle cars or other underground heavy vehicles or trailers.

The Tow Hitch results in minimal risk of an accident by an uncontrolled movement of the towed vehicle. It is also likely to result in the reduction of damage to machinery and infrastructure as well as reducing labour levels for this type of recovery application.
