Replacement parts and supplies as well as equipment rebuilding for the South African mining industry — at your service!
Most of our high quality replacement parts are either manufactured in our own specialized machine shops in South Africa or the United States, or purchased from specialty machinists who manufacture to our specifications. Many parts are proprietary to Gauley Robertson. Replacement parts such as chain, flights, sprockets, shafts, gears, etc. are designed to replace items made or supplied by equipment manufacturers such as Joy, Fletcher, Long-Airdox, S&S, Stamler, Eimco, Wagner, etc.
By buying from a distributor such as Gauley Robertson instead of the OEMs, rebuilders and mines save handsomely.
In collaboration with our US sister company, we supply many manufacturer’s products. Many of these items can be stocked locally for quick delivery to local mines and rebuilders. If not in stock, we can import on short notice.
Exchange components such as traction planetaries, gathering pots, reducers, wheel units, clutch assemblies, etc. are re-manufactured by Gauley Robertson and sold as refurbished components – representing large savings to operators.
- Shuttle Car Planetaries – Manufactured from high quality manganese castings, Gauley Robertson planetaries will give outstanding service in operation.
- Brake Assemblies – Electrolytic nickel plated housings are one of the features which make Gauley Robertson’s brake assemblies so popular.
- Continuous Miner Torque Shafts – Gauley Robertson’s well proven torque shafts and spooling devices are exclusively used by a number of major mines in South Africa and overseas.
- Spooling Devices
- Wheel Units

Our Products
Conveyor
Ox Chain
The “OX Chain” is a derivative of European Standard mining chain that has been adapted to suit the Coal Mining Industry providing a cost effective solution for discharge conveyors used on all types of shuttle cars.
Ox Chains are made so that all mating parts are engineered to form a reliable long lasting assembly. Metallurgical selection is a key consideration to ensure optimal life is achieved without compromising strength and wear life. The expectation is that the chain will last for about 400,000 tons or rebuild to rebuild, subject to maintenance practices and mining conditions.
Shafts
Gauley-Robertson SA manufactures most take-up and drive shafts for shuttle cars. In most cases our engineers have improved these to provide maximum life through careful selection of material and strengthening where required.
The shafts are available in various width selection to suit most applications. These include shafts for, Joy nominal 3 1/4 in pitch, Cincinnati 2 7/8 in pitch and the 18 x 64 Ox Type conveyor chain.
Flight Chain
Gauley-Robertson SA flight chain is 100% locally South African. It is available as a nominal 5 1/4 ” or 6” pitch dual flighted chain making it directly interchangeable with other non OEM flight chains for, continuous miner, shuttle cars, gathering arm loaders etc.
With the exception of the connecting pin, all parts are hot upset forged. Pin and connectors have been metallurgically selected to provide maximum life as well. The Chains are available in a various widths to suit most applications.
The chains have been specifically designed to carry the load on the “center string” rather than on the flight bar ends in order to increase overall life. Length can be assembled to suit the application.
Standard flight section widths
570 mm (22.44 in.)
673 mm (26.49 in.) (Joy D Car)
750 mm (29.52 in.)
810 mm (31.88 in.)
Sprockets
Gauley-Robertson SA makes a variety of sprockets for mining chains from carefully selected material and heat treated to provide maximum life.
All sprockets are field proven.
Bearing Carrier
The Gauley-Robertson SA Bearing Carrier has been specifically designed to give maximum trouble free life. It was developed in conjunction with major mining house engineers in South Africa.
It can be supplied as a direct fixture onto the body or mounted onto a removable plate. It is also available with a “sealed for life” bearing.
Track Chains
12 HM Series
Gauley-Robertson SA’s 12HM range of chains are suitable to be used on the Joy HM9, HM21, HM31 as well as the “Matla Miner”.
The chain is manufactured using a forged process and grouser configuration can be adapted to customer site application.

14 BU Series
The Gauley-Robertson SA’s 14BU Loader crawler chain is manufactured from a high quality casting and has the added feature that the hinge pin is not pressed in making maintenance on the chain safer and easier.
Other Products
Brake Calliper
Gauley-Robertson SA researched the application of the open type calliper and developed this in order to suit the tough applications in the South African Coal mines. The brake has been independently tested and found to have spurious stopping power.
The calliper is repairable and has repair kits that can be purchased for field repair.
Spooling Shaft
Gauley-Robertson SA’s spooling shafts have been designed and manufactured to provide maximum life by matching each part and the clearances to the interfacing assembly to ensure trouble free cable spooling.
