Frequently Asked Questions

  • How often should plant equipment be serviced?

    Most plant and heavy machinery should be serviced every 250 to 500 operating hours, depending on how it’s used and what conditions it’s working in. Sticking to a regular maintenance schedule helps prevent breakdowns, maintain safety, and extend the lifespan of the machine. High-use or high-impact equipment may need more frequent servicing, and many sites require documented servicing for compliance.

  • What’s included in heavy machinery servicing?

    Servicing generally includes checking and replacing fluids, filters and lubricants; inspecting hydraulics, belts and hoses; assessing tyre or track wear; and ensuring safety systems are functioning. Some services may also involve computer diagnostics or performance tests depending on the machinery and the issue. The goal is to prevent future failures and catch problems early.

  • Can repairs be done on-site?

    Yes, many plant and heavy machinery repairs can be done on-site using mobile repair units. These are equipped with the tools and parts needed to handle everything from hose replacements and electrical faults to engine diagnostics and emergency repairs. On-site repairs save time and eliminate the need to transport large equipment to a workshop.
