Komatsu HD1500-8

Description

The Komatsu HD1500-8 is a rigid dump truck in the 139-tonne class, developed for high-volume, efficient hauling in mines, quarries and large open-pit operations. Komatsu describes it as a mechanical haul truck, with a diesel-mechanical drivetrain. The designation HD1500 refers to Komatsu’s HD1500 series of rigid dump trucks, where -8 indicates the model generation.

The rated payload is 139 tonnes. The body is available in two sizes: 78 m³ heaped (50 m³ struck) and 94 m³ heaped (63 m³ struck), measured to SAE 2:1. Empty weight is approx. 110,400 kg and gross vehicle weight approx. 249,580 kg, with a maximum travel speed of 56.5 km/h. See the full specifications on the supplier’s product page, and browse more machines in Hesselberg’s dump truck category.

The truck is powered by a Komatsu SDA16V159E-3, a 16-cylinder, turbocharged diesel engine of 50.5 litres. It delivers 1,180 kW (1,580 hp) at 1,900 rpm (gross, SAE J1995), or 1,170 kW (1,570 hp) net (ISO 9249 / SAE J1349), with a maximum net torque of 7,378 Nm. It complies with EU Stage V using a selective catalytic reduction (SCR) system with a 212-litre DEF tank. The engine has an automatic pre-lubrication system, and the cooling fan is driven via a fan clutch which, according to Komatsu, helps limit fuel loss and overcooling. The operator can choose between Power and Economy modes. The transmission is a fully automatic planetary type with 7 forward speeds and 1 reverse, controlled by Komatsu’s K-ATOMiCS with automatic clutch modulation and a skip-shift function that selects a gear based on the slope when driving uphill without shifting down through every gear.

The brakes are fully hydraulic, oil-cooled multiple-disc brakes on all four wheels, which also act as the retarder with an absorbing capacity of 1,750 kW (2,346 hp) at 40 °C ambient temperature (Komatsu states that performance varies with temperature). Auto Retard Speed Control (ARSC) lets the operator set a constant downhill speed, and the Komatsu Traction Control System (KTCS) monitors wheel slip on the rear wheels and applies the brake automatically when needed. Suspension consists of MacPherson strut front suspension and a four-link rear axle suspension, both with hydropneumatic cylinders. The minimum turning radius is 11.2 m, which Komatsu highlights as the smallest in its class, and the tyre size is 33.00 R51. The body is made of high-tensile-strength steel (400/450 Brinell) with a V-shape and V-bottom design, and body exhaust heating is standard. According to Komatsu, the 78 m³ body is intended for high-density material such as copper and iron ore and hard overburden, while the 94 m³ body is intended for lower-density material such as loose overburden and dry soil.

The cab complies with ROPS to ISO 3471 and FOPS to ISO 3449 level II, and the noise level at the operator’s ear is 70.9 dB(A) (ISO 6396). It has automatic climate control with cab pressurisation, an air-suspended seat with heating and ventilation, a trainer seat, a tilting and telescopic steering column, a 7-inch LCD monitor and a radio with Bluetooth. Safety equipment includes the KomVision 360-degree monitoring system with six cameras, a rear-view camera with a dedicated monitor, a pedal-operated secondary brake, automatic and manual secondary steering, full LED lighting, a diagonal stairway with slip-resistant plates and a range of electronically controlled protection functions against, among other things, overrun and incorrect gear selection.

For daily maintenance, the HD1500-8 has a ground-level service centre for filling engine oil, coolant, transmission oil, steering and hoist oil and brake cooling oil. An automatic greasing system with a ground-level refill port is standard, the filters are centralised for easy service, and the fan drive belt has an automatic tensioner. Individual radiator tubes can be replaced without replacing the whole core. Komtrax Plus with satellite communication (Iridium) is standard and provides remote monitoring and road condition analysis, among other things, and the payload meter (PLM) is standard.

The HD1500-8 is the largest of the mechanical dump trucks. If you need something smaller, the HD785-8 (895 kW / 1,200 hp, 92.2 t payload) is an alternative, and for even greater capacity, see the electric mining truck 730E-10.
