A giant mining truck or an underground longwall shear is an assembly of extraordinarily expensive, precision-engineered systems, all of them ultimately dependent on hydraulic hoses and fittings that cost a fraction of the machine’s value. That mismatch in cost versus consequence is exactly why hydraulic hose failure remains one of the more preventable causes of unplanned downtime and safety incidents on mine sites. A burst hose under high pressure is not only an inconvenience, but can spray hydraulic fluid at dangerous velocity. Depending on the application, the failure can halt an excavator, a drilling rig, or an entire longwall face until a replacement assembly is sourced and fitted.
Melbourne-founded RYCO Hydraulics — which began manufacturing hoses, fittings, and filters since 1946 — has spent more than 70 years supplying the mining industry, where getting this component right is harder than it looks.
Matched systems, not generic parts
RYCO’s central technical claim is that its hose assemblies use only RYCO hoses matched with RYCO fittings rather than mixing components from different manufacturers. This matters more in hydraulics than in most other mechanical systems because a hose and fitting combination is only rated to its stated working pressure when the two components are engineered and tested together. Pairing a compatible-looking fitting from one supplier with a hose from another can quietly reduce the pressure rating or seal integrity of the assembly. Such is a risk that can remain invisible until the assembly is under load.
RYCO says its products can comply with or exceed independent third-party accreditations and relevant standards, including ISO, standard on assurance engagements (SAE), and the European standards (EN/DIN). These accreditations and standards give procurement and maintenance teams an objective basis for specifying hose assemblies rather than relying on supplier assurances alone.
Built for equipment that cannot afford to fail mid-cycle
RYCO’s mining and underground product applications span some of the most demanding equipment on a mine site: giant excavators, rigid and articulated mining trucks, longwall shears and roof supports, drilling rigs, man transporters, shuttle cars and bonded hose sets. Each of these applications carries a different combination of pressure, abrasion, temperature and confined-space constraints. RYCO’s spiral and wire-braid hydraulic hose range, alongside its couplings and adaptors, is designed to be specified against those variables rather than treated as a one-size-fits-all product.
Underground applications add a further layer of difficulty. Hose runs on longwall equipment and roof supports operate in confined, high-vibration environments where a failure is harder to access and repair quickly than on surface equipment. This makes hose and fitting reliability a more direct driver of safety outcomes and production continuity underground than it typically is in open-cut operations.
Reducing human error at the point of assembly
One of the more overlooked risk points in hydraulic hose reliability is not the manufactured product itself but the crimping process used to assemble hose and fitting on site or in a workshop. An incorrectly crimped fitting can fail well below its rated pressure, regardless of how well the underlying components were engineered.
RYCO’s Crimp App and companion web tool provide technicians real-time access to current crimp specifications, along with saved parameters, print functionality for workplace reference, and a Technical Centre offering in-depth guides on best practice. For maintenance teams managing dozens or hundreds of hose assemblies across a fleet, having a single, current source of crimp specifications reduces the chance of an outdated or incorrect setting being applied during assembly.
Scale backed by a global manufacturing network
RYCO’s growth has been shaped by both organic expansion and consolidation. In February 2020, Manuli Rubber Industries acquired a majority shareholding in RYCO, which subsequently became part of the Manuli Ryco group’s manufacturing division. Manuli Rubber Industries acquired full ownership of RYCO in 2022.
The combined group operates quality-accredited manufacturing facilities in Australia, China, Malaysia, and Europe. The group is then supported by a global network of distribution centres, offices, and original equipment manufacturer (OEM) hose assembly centres across North America, Europe, China, and Southeast Asia. RYCO says this manufacturing and distribution network supports consistent supply, quality control, local sourcing, and technical assistance close to the point of use.
A component that deserves more scrutiny than it gets
Hydraulic hose and fitting selection rarely receives the same procurement attention as the machines to which the components are fitted, yet the failure can be disproportionately disruptive relative to the component’s cost.
For mining operators and maintenance planners assessing hose assembly suppliers, RYCO’s combination of matched hose-and-fitting engineering, compliance with relevant standards, application-specific product ranges for surface and underground equipment, and digital tools supporting correct assembly at the point of crimping addresses the reliability question from manufacture through to installation.
