Providing Transport Equipment Repairs & Service


What makes Chassis Line unique is its approach to specialisation and customisation and its pursuit of a niche market. “Over the years, we have gained a strong understanding of what does and doesn’t work from a practical standpoint when building a specific trailer” says owner Warren Southee.

Rather than compete directly with the bigger manufacturers and particularly more so everyday with Chinese imports, we pride ourselves in supplying quality custom-built products for the heavy haulage and mining industry. That is our strength and our identity.

We pre-empt failures in our designs structurally and component-wise by applying our 30 years’ experience repairing other manufacturers’ product failures.

Many other engineers design equipment that comes to us cracked, broken or failed and we then redesign that vehicle to ensure durability and structural soundness.


In 1984, Warren Southee established, in conjunction with a partner, a new competitive workshop to service the heavy haulage repair industry.

Re-labelled Chassis Line in 1989, Warren continued to expand and push the business to its limits. Over the years, Chassis Line has provided significant service to the insurance repair industry as well as assisting transport operators to meet the requirements of Queensland Transport legislation. Starting as a two-bay workshop, a crush was the first installation. The ability to straighten and repair trailers and trucks damaged in accidents consolidated the business’ success and to this date, the crush remains an integral part of the business’ services.

Over time, additional bays were constructed and processing equipment was gradually added to the business’ capabilities. The workshop now boasts eight bays as well as a materials processing division with a floor area in excess of 1000 square metres.

A distinct advantage is the road train access to the yard and the cranes and forklifts to unload transport. When starting out, the workforce consisted mostly of boilermakers.

The workforce now additionally incorporates engineers, diesel mechanics, fitters, sandblasters and CNC equipment operators. The processing division incorporates an Omax Waterjet cutter, CNC plasma cutter, CNC band saw, subarc welder, guillotines, pressbrakes and pipe bender.
