Constructions we supply
| Family | Typical construction | Typical use |
|---|---|---|
| R1 / 1SN | 1 steel braid | Return, pilot, low-medium pressure |
| R2 / 2SN | 2 steel braids | Most mobile-machine working lines |
| 4SP | 4 spiral steel layers | High-pressure, medium sizes |
| 4SH | 4 spiral steel layers, heavier | Large-bore high-pressure lines |
| R13 / R15 | 4–6 spiral layers | Severe impulse duty on mining machines |
| Thermoplastic | Polymer core, fibre braid | Specialist and low-volume lines |
Exact ratings depend on size and on the hose make quoted. We confirm working pressure, minimum bend radius and temperature range for the specific hose in the quotation.
Temperature and cover choices for Ghana
Heat soak, not just sunshine. [FACT] The 2017 Tarkwa-Nsuaem municipal profile reports temperatures around 26–30 °C for that municipality. [INF] Regardless of ambient conditions, hoses routed past engines, turbochargers and hydraulic coolers on a haul truck can sit far above ambient for a full shift. For those positions we look first at the hose's continuous temperature rating and only then at pressure.
Abrasion-resistant covers. Laterite grit is abrasive in both its wet and dry forms. For hoses that run in bundles or across frames we offer abrasion-resistant covers and sleeves, so that a worn cover is caught at inspection rather than after a leak.
Fire-resistant cover. Fire-resistant (MSHA-type) cover hose available on request, typically for underground machines or positions near hot surfaces. We state the cover type in the quotation; we do not claim an MSHA approval held by RHPL.
Large bore for big fleets. Ultra-class trucks and large excavators use large-bore 4SH, R13 and R15 hose on main working and hoist circuits. For these sizes, confirm that the workshop has compatible fittings, approved assembly data and sufficient crimping capacity; finished assemblies are another option.
Bulk hose for Ghanaian hose shops
If you run a hose shop or mining-service workshop with suitable crimping equipment, we can quote bulk hose by the metre together with matching ferrules and fittings, so that hose and fitting series stay compatible. A workshop requirement can include: - R2 in the common working sizes for excavators, loaders and graders - 4SH and R13 in the larger sizes for haul-truck and shovel circuits - R1 and textile-braid hose for pilot and return lines - Ferrules matched to each hose series, plus JIC, ORFS, BSP and SAE-flange fittings
If your company supplies mining companies, you may also fall under the Minerals Commission's local procurement list as the Ghanaian seller; see Local Supply Partners.
Using the size table
Hydraulic hose is ordered by inside diameter, expressed as a dash size (sixteenths of an inch) or in millimetres. A -12 hose is 3/4 inch (19 mm) inside diameter. If you are unsure, send the layline printing from the old hose; it usually states the standard and size.
Questions before an enquiry
Useful answers.
Which hose suits hot engine-bay positions on Ghanaian trucks?
Look at the temperature rating first. Send the position and we propose a hose whose continuous rating fits the duty, plus heat sleeving where needed. The specification is stated in the quotation.
Can I order hose by the metre for my workshop in Ghana?
Yes. We quote bulk hose by the metre with matching ferrules and fittings. Minimum quantities, packing and delivery terms are stated in the written quotation.
Do you make the bulk hose yourselves?
No. Raipur Hydraulics builds assemblies and machines fittings in-house. Bulk hose comes from established hose manufacturers, and the make and standard are named in the quotation.
Is fire-resistant hose available?
Fire-resistant (MSHA-type) cover hose is available on request. We state the cover type; we do not claim to hold an MSHA approval.
