HYDRAULIC CYLINDER OVERHAULS

Hardchrome Sales specializes in hydraulic cylinder overhauls for the largest and most heavy-duty hydraulic machines.

From heavy overhead cranes to large, powerful stripping benches, our operation is purpose-built and laid out to ensure swift processing of large excavator cylinders, luffing cylinders and suspension cylinders – among others – to a very high standard.

The end-to-end repair process includes hard chrome plating, welding, machining, fitting and testing of all components including barrels, rods, clevises, pistons, and glands.

Streamlined Digital Repair Workflow

Our technology-led repair process is governed by an industry-first digital hydraulic repair workflow management system called Frontrunner. Using tablet computers to record and progress repairs at every stage, Frontrunner streamlines the repair process while ensuring 100% adherence to industry-standard repair procedures and accurate job history reporting.

THE HYDRAULIC CYLINDER REPAIR PROCESS:

Using heavy overhead cranes, powerful disassembly benches and specialized, diagnostic tools, our experienced technicians meticulously dismantle cylinders with a forensic eye.

Non-destructive testing is performed and accurate measurements are taken at every stage of disassembly. Care is taken not to damage to components such as cylinder rods, pistons, glands and seals, which may offer clues regarding the performance of the cylinder. Attention is given to the signs of expected and unexpected wear in order to assess the cause of failure in order to make accurate and precise recommendations for repair.

Using the Frontrunner digital repair process, everything is photographed, measured and recorded using both digital and manual measurement techniques. Offering you complete transparency and confidence. Helping you to understand what is happening within your important hydraulic components.

Barrels are checked and measured during disassembly and assessed for damage such as scoring and gouging of barrel walls.

Our large automatic tube honer is used to remachine worn barrels to prescribed specifications, restoring bore concentricity and surface finish to prevent premature failure in future.

In the case of extreme failures such as cracked or ballooned barrels, we can even manufacture new barrels on-site and bore them to the specified diameter in our end-to-end process.

Our in-house hard-chrome plating facility restores chrome to cylinder rods in an end-to-end service that includes electroplating, cylindrical grinding, and polishing.

Our operation boasts some of the largest and deepest chroming tanks in the country. With 7 tanks of varying dimensions, along with our large cylindrical grinders we have the capacity to accommodate even the largest hydraulic cylinders found on today’s mining machines.

Keeping this process in-house means we can ensure quality is up to our standards while cutting down on lag times and speeding up repairs.

Cylindrical grinders are used to remove old chrome in preparation for hard chrome plating and adjusting the thickness of chrome material after plating – in accordance with manufacturers specification.

Our large, high precision grinders give our highly experienced operators the ability to fine tune the finish of virtually any size rod with pin-point accuracy to maintain strict tolerances and quality controls. Ensuring every replated rod conforms to tolerances and meets the specifications for surface finish and chrome thickness.

Our surfaces finishes are regularly tested to equipment manufacturers guidelines and our polishing techniques help improve the life of your item.

Our welding department is fully equipped to offer several welding processes including Automated Internal Diameter Welding, Automatic Submerged Arc, Mig, Tig and stick Welding.

This gives us the capability to add new material to worn component parts with incredible accuracy, speed and efficiency. Even severely cracked or badly worn components such as clevises and clevis eyes, flange mounts, trunnion mounts, worn barrel mouths and more, can be expertly welded, remachined and returned to service to a safe working condition.

This in-house operation allows us to salvage existing components and cut down on cost and repair time.

Hardchrome Sales is equipped with a full machine shop featuring an array of lathes and milling machines capable of restoring and remachining any hydraulic cylinder component and restoring it to OEM specifications.

All operators are fully trained and qualified in the relevant trade and adhere to rigid engineering procedures at all times, in accordance with strict quality control processes.

Whether it is cylinder glands, rods, pistons, barrels, clevis eyes, everything can be machined to the micrometer inhouse returned to service with as-new performance and lifespan expectations.

Our fully-equipped engineering division enables Hardchome sales to design and manufacture a host of component parts if necessary including;

Complete hydraulic cylinders, cylinder rods, barrels, pistons, glands, guide bushes, pins and shafts.

This capability not only means that we can salvage existing components and reduce the need to purchase new ones. It also means we can cut down on repair time by eliminating the time it takes to source and transport new components from overseas source plants.

Moreover, where required, we can produce upgraded or reinforced components if specified by the customer – to increase the service life where possible.

Cylinders are fully Crack Tested, Sand Blasted and assembled in a quality controlled environment, with full pressure testing to ensure your products are correct. Full photographic and dimensional reporting is provided with all repairs.
