Specialist waste and recycling company Dunmow Waste Management has added a JCB 457 HT Wastemaster wheeled loader to its growing fleet, to handle an increasing volume of material at its Chelmsford, Essex head office site. Painted in Dunmow’s distinctive white livery, with highly visual red chevrons at the rear, the machine is equipped with super high-lift loader arms, a 4.5m3 toe-tip bucket and SG Revolution solid tyres. The loader also comes with a full rear radar system, auto lubrication, a weighing system, fire suppression and a deluxe operator’s seat.
Dunmow has chosen to specify the machine with the optional five-speed ZF transmission with lock-up torque converter, which locks the transmission in every gear from second to fifth to prevent losses and reduce fuel consumption. However, while this transmission has been primarily designed to provide maximum efficiency on longer load and carry operations, the company is not looking for maximum travel speeds.
Instead directors Sam Malins and Edward Barnes calculate that third gear in the five-speed transmission is lower than third gear in the four-speed box, which was used on the firm’s previous 456 loader. This lower ratio allows the operator to use third gear smoothly and productively within Dunmow’s recycling operation, reducing fuel consumption and increasing performance.
"The main benefit is the torque lock-up from second gear, so there is no wastage," says Mr Barnes. "Third gear in the four-speed transmission was too high, so the machine was too fast. This option preserves the tyres and reduces fuel consumption. The operator is very happy with it, it’s a lot more nimble and so smooth. We hope to get a 5% fuel improvement in the long term. It’s never going to be 20-30%, but 10 litres per day is all worth it.
"The loader also has a Stage IIIB/Tier 4 Interim engine and as it spends half of its time in an enclosed building the significant reduction in emissions was an important factor for us."
Dunmow Waste Management has been in the waste and recycling business since 1992, mainly in skip hire and waste disposal, serving construction, demolition, domestic and local authority customers. With 70 staff operating throughout North London and Essex, Dunmow has a licence to handle up to 150,000 tonnes of waste material at the Chelmsford site each year. The company is proud to be one of the first waste management companies in the UK to offer a zero to landfill service and is committed to ensuring that as much material as possible is recycled, reused or recovered.
The company moved to its current site near Chelmsford in June 2012, having outgrown its original Little Dunmow operation. It runs 20 trucks on the road and operates a mixed fleet of materials handlers and wheeled loaders, including a JCB JS130 tracked excavator, a JCB 436 Wastemaster wheeled loader and the new 457 HT.
"We like the JCB machines because they are British," says Mr Barnes. "But also JCB is a very open company to deal with. JCB is a multi-billion business but they are always interested in talking to us and finding out about our company . They are interested in what we do."
Dunmow’s previous 456 loader had completed 7,000 hard hours of operation for the company and with support from local dealer Greenshields JCB the decision to move to the 457 was an easy one to make. Greenshields will provide complete back-up for the machine under a three-year repair and maintenance plan and both Dunmow and the dealer have instant access to machine performance data through JCB’s LiveLink telematic monitoring system, which is standard equipment on the 457.
With increased performance, lower fuel consumption and emissions, improved comfort and control for the operator and the potential for increased efficiency, the 457 HT Wastemaster takes JCB wheeled loader productivity to a new level. By equipping the machine with the five-speed transmission and lock-up torque converter, Dunmow Waste Management is taking that performance even further, maximising productivity and return on investment.
