HM400-3R

HM400-3R

Overview

This 40-tonne capacity truck is powered by a new technology Komatsu engine and features advanced Komatsu Traction Control (KTCS), transmission, hydraulic braking and retarder systems for unrivalled traction, braking power and safety in all applications. As with all Komatsu’s trucks, key components are designed and manufactured by Komatsu to work together in an integrated package

High Performance Komatsu SAA6D140E-5 Engine
Powerful turbocharged and air-to-air aftercooled Komatsu SAA6D140E-5 engine provides 338 kW 453 HP. This engine realizes high power with low fuel consumption by Common Rail Injection system, and thus it delivers higher travel speeds with high horsepower. In addition, high torque at low speed, impressive acceleration, and low fuel consumption ensure maximum productivity.  This engine is EPA Tier 2 and EU Stage 2 emissions equivalent.

Increased Body Capacity And Box Section Frame Structure
Increased the payload to 40.0 metric tons by increasing the body capacity.  The HM400-3R has the 24.0 m3 heaped capacity body. The low loading height of 3164 mm enables easy loading.  The body is built of high strength wear-resistant steel with a Brinell hardness of 400, and the body shape provides excellent load stability.  HM400-3R’s frame is designed using a rigid box structure used high tensile strength steel, and rugged enough for the toughest jobs.

Low Fuel Consumption
New variable displacement piston pump for reducing Power Take Off (PTO) pressure loss, improvements in transmission and axles for increasing energy saving, and the sophisticated electronic control of the engine operation to achieve optimal energy efficiency, all combined.  Fuel consumption maximum 14.0 % reduction Compared with the HM400-2R. Fuel consumption varies depending on job conditions.

Komatsu Designed Electronically Controlled Countershaft Transmission
The Komatsu designed electronically controlled transmission called Komatsu Advance Transmission with Optimum Modulation Control System (K-ATOMiCS) has been a success in Komatsu’s rigid dump trucks.  The electronic clutch modulation system ensures proper clutch pressure when the clutch is engaged. The total control system controls both the engine and the transmission by monitoring the vehicle conditions.  This high technology system assures smooth shifts without shock and maximizes the power train life.
