Practical undercarriage solutions from Tilly’s Crawler Parts can make a measurable difference in an industry where wear and tear is inevitable
In the earthmoving industry, undercarriage performance is often the difference between productivity and costly downtime.
It is an area where precision matters, but so does practicality. At Tilly’s Crawler Parts, the focus is on delivering complete, fit-for-purpose undercarriage solutions backed by hands-on capability and a clear understanding of how machines operate in the field.
With more than 30 years’ experience supplying to the oil and gas industry, Tilly’s brings a depth of knowledge shaped by demanding environments where reliability is critical.
That experience carries through into every undercarriage solution, ensuring products and assemblies are built to withstand tough operating conditions.
Working across excavators and bulldozers from 5 tonnes through to 50 tonnes, the team supplies a full range of undercarriage components including shoes, chains and complete track groups.
These are not simply off-the-shelf parts. They are supported by workshop-based services that ensure each system is correctly assembled, adjusted and ready for work before it leaves the yard.
A key part of that capability is the onsite track shed in Toowoomba. Purpose-built for undercarriage assembly and servicing, it allows for efficient bolt-up work to be completed pre-sale.
This approach reduces installation time on site and gives operators confidence that everything has been properly aligned and tensioned prior to delivery.

It is a practical step that helps avoid common issues that can arise when components are fitted under pressure in the field.
Beyond standard supply, Tilly’s also provides tailored undercarriage solutions for specialised applications.
This includes full track bases and assembled leg sets in the 15-tonne to 30-tonne range, designed to suit equipment such as screening plants, drill rigs and blast rigs.
These applications often require more than a standard configuration, and the ability to modify or customise components ensures the final product matches the demands of the job.
Flexibility is central to this offering. Whether it is adjusting track dimensions, configuring bases for specific loads, or adapting assemblies for unique machine setups, each solution is built with its end use in mind.
This level of customisation is increasingly important as machinery becomes more specialised and project requirements become more varied.
The workshop also supports chain lengthening and shortening services, allowing existing undercarriage systems to be modified rather than replaced outright where appropriate.
This provides a practical option for operators looking to extend the life of their equipment or adapt it to a different application without committing to a full replacement.

In addition, Tilly’s carries out spot repairs across all excavator and dozer sizes. These repairs are completed onsite in Toowoomba, where the team has access to the right tools, parts and environment to deliver consistent results.
By focusing on workshop-based repairs rather than field service, the emphasis remains on quality control and efficiency, ensuring machines return to work ready to perform.
What underpins all of this is a straightforward philosophy. Undercarriage systems should be built to suit the job, not forced to fit it.
That means understanding how a machine will be used, the conditions it will operate in, and the level of durability required. From there, the right combination of components and services can be applied.
In an industry where wear and tear is inevitable, having a reliable partner for undercarriage supply and support makes a measurable difference.
With a combination of standard components, custom-built solutions and workshop expertise, Tilly’s Crawler Parts continues to deliver practical outcomes for operators who rely on their equipment every day.
