Description
The Komatsu HD325-8 is a 36.5-tonne class rigid dump truck, built for hauling large volumes of material in quarries and mines. The designation HD325-8 refers to Komatsu’s HD325 series, with -8 indicating the model generation.
It is powered by a Komatsu SAA6D140E-7, a 6-cylinder 15.24-litre common rail diesel engine delivering 386 kW (518 hp) at 2,000 rpm. Nominal payload is 36.5 tonnes, and the standard body holds 24.0 m³ (SAE 2:1 heaped) or 16.9 m³ struck. Empty weight is 34,180 kg, gross vehicle weight is 70,760 kg and top speed is 68 km/h. See the full product information from the supplier and all Komatsu dump trucks at Hesselberg.
The engine complies with EU Stage V using a Komatsu Diesel Particulate Filter (KDPF) and SCR with AdBlue, and Komatsu states that NOx emissions are reduced by 80% compared with EU Stage IIIB. Komatsu also states that power is approximately 5% higher than on the previous generation, with the power train redesigned to handle the increase. The transmission is the fully automatic K-ATOMiCS with seven forward gears and one reverse, and the skip-shift function automatically selects gear according to the slope to reduce the number of downshifts. Eco-gauge, Eco guidance and adjustable auto idle shutdown are standard. The Komatsu Traction Control System (KTCS) is available as an option.
The brakes are fully hydraulic, with disc brakes at the front and oil-cooled multiple-disc brakes at the rear. The rear brakes also act as a retarder with 689 kW (924 hp) of continuous capacity, and Auto Retard Speed Control (ARSC) lets the operator set a constant speed on downhill slopes. The front suspension is a MacPherson strut type with an A-frame, and the rear is a four-link type, both with hydropneumatic cylinders. This gives a turning radius of 7.2 m measured to the centre of the front tyre. The frame uses cast steel in high-stress areas, and the body is made of high-tensile steel with exhaust heating as standard. Steel body liners and side extensions are available as options.
The Komatsu SpaceCab meets ROPS/FOPS (ISO 3471 and ISO 3449 level II) and has air conditioning and an air-suspended seat with heating and ventilation. A trainer seat, a large LCD colour monitor and a rear-view camera are standard. Supplementary steering and secondary brakes are standard, while an antilock brake system (ABS) and an overload speed limiter are available as options. Engine oil is changed every 500 hours, transmission oil every 1,000 hours and hydraulic oil every 4,000 hours, and the battery box and battery disconnect switch are accessible from ground level. The KOMTRAX wireless monitoring system is standard.
If you are comparing with a larger truck in the same series, the Komatsu HD405-8 has the same 386 kW (518 hp) engine but a payload of 40 tonnes and a 27.3 m³ body. The HD325-8 offers 36.5 tonnes of payload, a 24.0 m³ body and a top speed of 68 km/h.
