ABOUT USTru-Trac is a world leading manufacturer and supplier of conveyor belt solutions to the mining and bulk material handling industries worldwide. Located in Centurion, South Africa, Tru-Trac has a well-established sales and service presence throughout Southern Africa and most major mining regions on the African continent. Tru-Trac has today grown into a major intentional supplier of specialist conveyor components with an international sales and distribution network spanning 80 countries.
Conveyors are the lifeline of efficient operations and for over 25 years, Tru-Trac has helped the world’s biggest mining houses process minerals more efficiently, reliably and safely. We’ve built a repository of industry knowledge, technical expertise and the necessary operational scale, that gives us the ability to solve any conveyor problem you might face.
The problems we solve
Our service starts with understanding the root cause of your conveyor challenges, as well as their impact on your mining operation.
With this knowledge as a foundation, we’re able to offer a full range of solutions for the following common conveyor problems:
• Belt Misalignment • Belt Cleaning • Impact, dust & spillage solutions • Belt fasteners • Safety Hazards• Component damage or failure Once the scope of your conveyor requirements are clear, we work with you to select the right product and ensure optimal positioning within your conveyor system.
Installation of your conveyor components is handled by trained professionals.

ANTI ROLL BACK IDLER
This one directional invention is a standard idler that is equipped with a brake system that prevents the idler from rolling back. Normally installed on long or steep inclines.
FUNCTIONS:
• The inner race turns in the forward direction, for normal operation without adding friction.
• Should anything happen, that the roller wants to turn back, the inner race wedges itself against the shaft and the narrow part of the outer race profile, will stop the idler.
ADVANTAGES:
• There will be no roll back, should the belt stop under load.• Belt will only run down a couple of meters should the belt snap.• Less down time to pull the belts back in.• No danger to workers when belt drops to the ground.• No damage to structure and equipment when belt drops

Tru-Trac frames are manufactured from graded material and jig manufactured. This means that the frames are manufactured symmetrical which allows for the idlers to be seated identically throughout the span of the conveyor system. This allows the conveyor belt to run seamlessly over the idlers without causing the idlers to bounce or vibrate.
All welding procedures are certified (AWS D.1.1) and all welders qualified to the procedure.
Receipt inspection takes place on all components to ensure that it conforms to the correct client specifications. The tubes are CNC bent to ensure every pipe is identical.
Tru-Trac mining frames uses a three-stage jig process:The first stage is manufactured according to the approved client drawing and uses toggle clamps, clamps to ensure that the parts for each frame remains fixed in set positions. Mounting pins on the jig ensures that the hole and fixing centres are placed correctly.
The second stage jig is utilised when welding up of the frames to ensure that no movement takes place during the final welding process. The third jig is used when the frames have had corrosion protection applied, whereby a final fitment takes place to ensure that prior to dispatch every frame is to specification.
Corrosion protection: Standard manufacturing tolerance in accordance with SANS 121.

UNDERGROUND STRUCTURES
Tru-Trac are able to supply floor standing or hanging structures in any configuration as illustrated. We are able to supply the stringers, stools, inner legs, frames or idlers individually. The components of the structure are laser cut, this ensures that the structure is of the highest quality and correctly aligned.
Thus preventing the belt from running out which prevents spillage problems and prevents damage to the belt, idlers, frames and structure. We are able to provide galvanized and painted structures.
