HD605 Rigid Dump Truck at Criggion Quarry
15/09/2004

The off-highway range of rigid dump trucks from Komatsu are employed in a wide range of applications throughout the world.  Available exclusively in the UK from sole distributor Marubeni-Komatsu, the trucks have an enviable reputation for high productivity and long life.

The latest addition to the range is the HD605-7, an off-highway truck which builds on the many features of its predecessors.   Excellent performance is ensured through its SAA6D170E-3 Komatsu engine which delivers Gross Horse Power of 551 kW 739 HP and a maximum torque of 332 kg/m.  Standard features include auto retard speed control, an automatic spin regulator (optional), an automatic idling setting system and a mode-changing system giving superb fuel economy, while options include Anti-Lock brakes and a Memory Card Type Payload Meter for analysing production volumes.  The seven-speed fully automatic K-ATOMiCS transmission automatically selects the optimum gear according to vehicle speed, engine rpm and the shift position chosen.

As with all Komatsu vehicles, attention has been paid to maximising operator comfort with an ergonomically designed cab which combines space with excellent visibility.    Also featured are an air suspension seat, a telescoping steering wheel and low effort pedals.

Recognising the ever increasing importance of the environmental impact of quarrying activities, Komatsu have designed the HD605-7 to meet the European Stage II Directive for EU Emissions, with low operation noise and low fuel consumption.

A Marubeni-Komatsu customer who has been operating the HD605 for almost a year is Hanson Aggregates at their Criggion Quarry in Shrewsbury.  The truck is operating in a ‘load and hold’ capacity, carrying aggregates from the excavator to the crusher along a 1 in 5 incline.  The 62 psv green stone quarried at Criggion is widely used in road surfacing applications.
