Smart Machines For City Rail Link Project

Ruakuri Caves

Sustainable solutions from Terra Power Systems

The facilities of Ruakuri Caves are powered by a Caterpillar Microgrid technology system, using a solar-powered battery system with diesel backup. This off-grid solution powers the ticket and tour office, cave lighting, and a nearby water pump for farm irrigation. Ruakuri Cave is one for the bucket list. It is one of several caves in the Waitomo, near Auckland, and it’s been named a must-do experience by a leading travel journalist.

Cat Reman and Sustainability


With sustainability becoming increasingly important, it’s great Caterpillar parts and machines can have more than one life thanks to remanufacturing or rebuilding.

Caterpillar has been remanufacturing components since 1973, saving energy and materials. Remanufactured – known as reman - parts are not just cleaned and reassembled. Caterpillar salvages, reengineers and remanufactures using state-of-the-art processes and technologies to recapture and renew the built-in quality and performance of the original part.

The production quality of Cat parts means they last longer and require less repair or replacement than other brands due to the high standard of the manufacturing process.

This has an immediate effect on both the environment, with less resources needed over a longer lifetime, and reduced running and maintenance costs for owners. And when a machine or parts do come to the end of their life, they can be remanufactured or rebuilt.

It’s a sensible as well as sustainable choice, with reman parts costing on average 40 per cent less than a new part without sacrificing quality. With Cat reman parts subject to such rigorous standards, they’re backed with a ‘same as new’ 12-month warranty.

Cat Certified Rebuild


In the same vein as reman parts, certified rebuilds give Cat machines or components an entirely new lease of life, restoring them to ‘like new’ quality and adding the latest critical updates and improvements. A certified rebuild can be more affordable than buying a new machine. It also supports the environment. Rather than selling or retiring your old equipment, Terra Cat can rebuild it.

Rebuilding your equipment lets you keep the machine you are familiar with and returns it to its original performance and productivity. This lets you get more value from your initial investment with a longer lasting and updatable machine.

Certified rebuilds do more than return a machine to a same-as-new state, they can add new features to an older model. When buying a machine, you may have opted out of extras you now need. These options can be fitted during the rebuild, saving downtime. New safety features, technology or parts will have been released since your purchase and can be added as well. This improves the machine to a better-than-new state and adds significant value.

Certified rebuilds are not limited to the entire machine. Certain systems or components can be rebuilt, saving money and disposal costs. Rebuilt engines run more efficiently, saving fuel, while hydraulics can be re-energised to increase efficiency. Engines, transmissions, hydraulic, and drive systems are only some of the components that can be individually rebuilt as desired. While reman parts save one part, a certified rebuild can save an entire machine from becoming waste and give it a new lease on life for many years to come.
