Innovative engineering

CAB_3Challenge: China-based North Haulage (NHL) was looking to sell its product to the Australian and international market and required a cabin design for its TR100 rigid body dump trucks, which met the safety requirements of the International Standardisation Organisation.

Solution: With a bit of clever engineering, QMW have designed a cabin that meets roll over protective structures (ROPS) and falling object protective structures (FOPS) safety standards, plus the visibility is better than what its competitors currently have to offer.

QMW design engineer Paul Cartwright who led the team on this project said the concept for the Vizmax cabin came about when the company was approached by China-based North Haulage (NHL).

“NHL produces a variety of products for the mining and construction sector, and what the company wanted from QMW was intellectual property in the form of a full cabin design for its TR100 rigid body dump truck, technical specifications and full workshop drawings,” Mr Cartwright said.

“It also required a full ROPS and FOPS, which was integrated into the cabin design that would be tested to ISO 3471 and 3449 in order for NHL to be able to sell the product to the Australian and international mining sector.”

Benefits included reduced cabin noise levels, better ergonomics, as well as the latest in automotive styling cues for both the interior and exterior.

“The integrated protective structure improves the visibility issue which can be caused by the after fitting of bulky cages on cabins, secondly it costs less.”

“It’s a clever bit of engineering and it meets international safety standards,” Mr Cartwright said.

The ergonomics of the cabin were very important to cater to the comfort of the operators, to avoid issues such as fatigue. Some features include, dust control inside the cabin, as well as a heating and cooling system that can withstand harsh weather conditions, especially in Australia.

Outcome: The project was run through QMW’s New Product Introduction Process (NPIP), Mr Cartwright said. The process reviewed the project at the various different stages to eliminate financial risk and ensure the reputation to both the customer and QMW were protected.

“This process ensures the product we deliver fits the clients purpose, is delivered on time and on budget,” Mr Cartwright said.

Feedback received from NHL from the testing phase of the cabin carried out at QMW’s facility in Brisbane last December was positive. NHL said it was impressed with how efficient QMW were and how well it met its needs.

QMW has also provided a similar service to Bucyrus, a subsidiary of Caterpillar.
