Komatsu 930E-5

Description

The Komatsu 930E-5 is a 290-tonne class electric drive mining truck, built for hauling large volumes of material in mines and large open-pit operations. The designation 930E-5 refers to Komatsu’s 930E electric drive series, with -5 indicating the model generation.

It is powered by a Komatsu SSDA16V160, a 16-cylinder diesel engine with two-stage turbocharging, rated at 2,014 kW (2,700 hp) gross at 1,800 rpm. Nominal payload is 290 tonnes (320 short tons) and nominal gross vehicle weight is 521,640 kg, against an empty vehicle weight of 231,331 kg. Top speed is 64.5 km/h, and the standard body holds 202 m³ (SAE 2:1 heaped) or 151 m³ struck. See the full product information from the supplier and all Komatsu dump trucks at Hesselberg.

The diesel engine drives a GTA51 alternator that feeds GDY106B wheel motors, controlled by the Invertex IIe AC system with IGBT inverters. Komatsu states that the system controls the rear wheel motors independently, giving good traction in wet and slippery conditions and improved tyre wear. Traction control for wheel spin and wheel slide and cruise control are part of the system. The electric dynamic retarder provides 4,027 kW (5,400 hp) of braking capacity on long descents. Cooling is split into separate circuits for the control group and the wheel motors, and energy from the retarder is used to cool the control group, wheel motors and grid blower.

The body is a Komatsu-designed all-welded steel body with a flat floor and full canopy. It is matched to the application through Komatsu’s Body Worksheet process, and the standard body weighs 36,228 kg. The frame uses steel castings in high-stress areas, and the hydraulic system uses a single tank shared by steering, braking and hoisting. The service brakes are oil-cooled multiple-disc brakes on all wheels, and Komatsu states that the system gives lower maintenance costs and higher reliability than dry disc brakes. The Hydrair II suspension is designed to give a smooth ride and protect the frame and components. The Payload Meter IV records data such as payload, cycle time and distance travelled, and the turning circle diameter is 32 m (ISO 7457).

The cab has an integral ROPS/FOPS Level 2 structure (ISO 3471 and 3449), air conditioning, a five-way adjustable air-suspension seat and a tilt and telescoping steering column. A touch-screen display in the cab gives access to setup, maintenance and troubleshooting. KOMTRAX Plus 2 is standard, and Komatsu states that the Eliminator oil filtration system reduces oil and filter changes by as much as one third. Service points for lubrication, fluid filling and emergency shut-down are grouped at the front left. The KomVision all-around monitoring system and Komatsu Smart Rims are available as options.

If you are comparing with a smaller mining truck, the Komatsu 830E-5 has 1,865 kW (2,500 hp), a nominal payload of 227 tonnes and a 158 m³ body. The 930E-5 offers 290 tonnes of payload, a 202 m³ body and 5,400 hp of retarding capacity.
