Three of a kind
What do trailer builders Jackson Transport Bodies, General Transport Equipment and Southern Cross Trailers all have in common? They all use TMC’s mechanical suspension as standard fit on their builds. 

 Jackson Transport Bodies (JTB) have been building customised trailers and truck bodies since 1980 and have a range that includes B-Doubles, drop decks, tautliners, wideners, tilt and slides, and dog trailers – to name just
a few.
The JTB quad axle deck widening float is a popular order amongst JTB customers and features an 11.5 metre long deck, a TMC self steer 19.5” axle, TMC mechanical 4/8/4 quad suspension and TMC 19.5” axles. With a total tare weight of 11,750kg, the unit gives a payload of 37,000kg and has a full phasing hydraulic widening deck.
Based in Warragul, Victoria, JTB say they primarily build custom trailers requiring different axle configurations to suit their customer’s needs.
“TMC supply us with a wide variety of custom track lengths and suspension options in the 19.5” range, which we incorporate into our many low loader and drop deck trailer designs,” explains Neil Cooper from JTB. “With our recent increase in productivity from 80 trailers to over 125 trailers per annum, TMC have been instrumental in supplying us with the products and service we require.”
Also utilising TMC suspensions are General Transport Equipment, who recently delivered two complete road trains to Hyrock in Western Australia. Used for carting Manganese, each trailer can hold 24 cubic metres of product and the entire road train configuration gives 120 tonnes of payload.
Running around the North West of Australia, Hyrock will run the road trains from “Woodie Woodie” to the port at Port Hedland, a round trip of around 800km. “All the units were fitted with TMC 2.7 metre spread mechanical suspensions and the latest spec TMC disc brake axles, including Conmet alloy hubs, 430mm rotors and Wabco PAN 22 disc brake callipers,” explains Barry Moon, Sales Director at General Transport Equipment.
“Hyrock are so pleased with the new running gear that they are going to change over their existing fleet to the same spec, which includes another two road train combinations that are set to be delivered in early 2008.”
The TMC mechanical suspension is designed to operate under harsh conditions. The company say it is simple and robust, and made to suit all types and makes of trailers.
Twin tapered bushes for both the equaliser and the torque arm assemblies offer extended life with minimal maintenance. Standard parts are used throughout to allow interchangability between models.
Southern Cross Trailers have been manufacturing their products since 1976, focusing on producing trailers that provide long-term reliability and low running costs.
The TMC product has definitely impressed Col Deverson, Managing Director of Southern Cross Trailers. “We have now standardised the TMC mechanical suspensions on our flat bed, drop deck and extendible trailers, most of which end up working in Western Australia, where spring suspensions are favoured over air bag,” he says.
“TMC are not the cheapest product on the market, but their quality is consistent, and there is never any problem with the supply. On the odd occasion we have encountered a problem, TMC have always fixed it straight away, no questions asked.”
According to Brendan Dullard, Managing Director of TMC, mechanical suspensions are a popular product, due to their strength and suitability.
This is especially the case for heavy-duty applications.
“TMC can consistently demonstrate a flexible approach that our customers really like. We offer more personalised customer service, faster response time and a higher degree of flexibility. This is what sets TMC apart from our competitors,” he says.
TMC say they keep a large stock of components on hand, which means that the average lead-time for a mechanical suspension kit is less than three working days.
“We are able to ship products out to the customer with little or no delay. That way the build process is not held up and the customer can get their new equipment on the road sooner,” Brendan explains.
“As a company, we have decided to no longer chase volume orders, instead we have opted to specialise and concentrate more on what our customers need – quality products that last the distance.”
