Construction and civil engineering
Mini excavators, backhoe loaders, access platforms, hydraulic breakers and compactors: arm hoses, breaker lines and flat-face couplings, crimped in the Riom workshop and replaced in the workshop or on site.
On site, hydraulics never fail in a convenient place. An arm hose torn off by rubble, a breaker line split open, a coupling that will not go on against residual pressure, an access platform cylinder weeping, and the machine sits in the middle of the earthworks. The machinery varies: mini excavators and excavators, loaders and backhoe loaders, access platforms, hydraulic breakers, reversible plate compactors and rollers.
Sites are scattered and the breakdown happens a long way from the workshop. Mud and rubble damage the sleeves and tear off hoses that are poorly clamped. Above all, attachment changes are frequent: at every coupling-up, whatever soil is left on the coupling face goes into the circuit. Flat-face couplings to ISO 16028 limit that ingress of dirt and the oil lost on disconnection, provided the dust caps are kept in place. Finally, some of this machinery is on hire: it has to go back in good order, with no leaks and no makeshift hoses.
- Arm, dipper and bucket hoses, in EN 853 2SN braid or compact EN 857 2SC for tight bend radii.
- Hydraulic breaker lines, in EN 856 4SP and 4SH spiral or SAE 100R13 to suit the circuit.
- ISO 16028 flat-face couplings and ISO 7241 series A or B couplings, mounting blocks and replacement sets.
- Boom, arm and outrigger cylinders, directional control valves and pilot-operated check valves.
We crimp your hoses in the Riom workshop, and we handle breakdowns and repairs in the workshop and out on site. For a machine that is down, tell us the machine and the component concerned: a photograph of the hose in place and of its hose ends saves a wasted trip. For a set of couplings, give us the series and the size: attachments have to stay interchangeable. If it is an access platform, say so: safety components are replaced like for like.
