South Africa's coal comes from two very different places. The Mpumalanga Highveld, around eMalahleni, Middelburg and Secunda, is a long-established coalfield with many mines, opencast and underground. The Waterberg, around Lephalale in Limpopo, is more remote and is known for very large opencast operations. This page explains how hose needs differ between the two. The sector is covered on the coal mining page.
RHPL has no premises, stock or representative in either coalfield. The towns are named only to describe where mining takes place.
Mpumalanga Highveld: many mines, many machine types
- Underground sections with continuous miners, shuttle cars, roof bolters and utility vehicles, where the mine's own safety specification sets the hose cover. Fire-resistant (MSHA-type) cover hose is available on request. RHPL holds no MSHA approval or certificate; acceptance follows the mine's own specification.
- Opencast pits with dozers, graders, excavators and trucks working high hours in coal dust.
- Washing plants with slurry and dense-medium circuits.
- Workshops close to the mines. Where local hose workshops already serve the coal mines, RHPL's trade supply and dealer model fit naturally: the workshop keeps its service, and RHPL manufactures behind it.
Waterberg: scale and distance
- Large opencast machines with high-impulse circuits and long operating hours, similar in duty to iron-ore pits but with coal dust.
- Distance from industrial centres. As in the Northern Cape, a missing hose on a planned job is costly. A complete, tagged kit can support a planned replacement scope. See planned-shutdown kits.
- Plant hydraulics in beneficiation and coal-handling plant.
Highveld vs Waterberg at a glance
| Factor | Mpumalanga Highveld | Waterberg |
|---|---|---|
| Mining method | Opencast and underground | Mainly large opencast |
| Hose focus | TMM and section equipment; high-hour opencast fleets | Large-bore, high-impulse opencast circuits |
| Specification driver | Mine's underground fire-resistance specification | Impulse class and abrasion |
| Best RHPL route | Trade supply to workshops; supply-company partnerships | Planned kits through approved vendors |
Price pressure and rebuilds
Machines in the coalfields
Dozers, graders, trucks and excavators from makers such as Caterpillar, Komatsu and Bell; underground machines from makers such as Sandvik and Epiroc, and many others.

Confirm the coal mine’s purchasing route
Coal mines, including those supplying power stations, may require registered South African vendors under their procurement policies. A Highveld or Waterberg workshop or supply company can use RHPL as its manufacturer: the partner imports, holds its own stock and invoices the mine, while RHPL builds, tests and tags. RHPL holds no B-BBEE certificate or level. See local supply partnership.
Public operating context
[FACT] An issuer statement in December 2025 reported completion and operational handover of coal-sector projects. Earlier construction descriptions should not be treated as current asset status. Public report.
[FACT] The operator’s 2026 interim reporting identifies rail constraints and equipment replacement as operating considerations. Shipment arrangements still need to be confirmed for each order. Public report.
