Caterpillar designs its machines from the ground up to ensure that each component performs beyond customer expectations and that each consumable item lasts longer.

A case in point is Caterpillar’s re-useable coupling system on its XT hydraulic hose series, an innovation that passes on savings of some 30% when compared with conventional assemblies with permanent couplings that are discarded with each new hose change.

“Detaching and reattaching Cat’s re-useable coupling system during routine hose replacement on a job site is now a simple task, allowing machines to get back to work as quickly as possible,” says Paul Verwey, group product specialist: hydraulics, at Barloworld Equipment.

As with its coupling system, Caterpillar has paid special attention to its hydraulic hose range with each line item carrying an individual parts tag number. This simplifies order placement, avoiding errors that could result in the wrong hose size being requested.

“Specifying the correct hose diameter and fitting it correctly are essential to avoid mechanical stress and malfunctioning,” Verwey explains, “since the right size determines the right demand of oil. Ordering the wrong diameter hose could result in pump failure where the hydraulic system has to work much harder to perform.”

Cat hose also undergoes pressure, strength, flexibility, bend radius and abrasion resistance tests; whilst Cat’s spiral wire design prevents hose bursts.

At each of its main branches, Barloworld Equipment has a dedicated hydraulics service centre equipped with a specialised hose bay. Around South Africa, these are being progressively updated.

When Barloworld technicians re-attach reusable couplings, each assembly is plugged and capped to prevent contamination from happening and prior to this final stage, a purpose-built tool is used to blow a projectile through the hose using compressed air to remove any residual dirt.

Adds Verwey: “A hydraulic system represents the arteries and veins of your machine and, in addition to being critical for performance, represents a sizeable percentage of your maintenance costs. Monitoring both areas on a daily basis will ensure that you get the best value from your machine.”
