Features and benefits

Safeguard your operators and work site

Operator and work site safety are a priority. Komatsu hydraulic excavators have an LED screen to give your operator a 360-degree view, each meet ISO 10262, 6394, 10263-4 safety stand-ards, and all include anti-slip gratings, easy ingress/egress and an innovative emergency es-cape system.

Customized to your operation

While Komatsu shovels and backhoes meet the density benchmark of 1.8 t/m³, you have the option to customize your machine to the bucket size and wear package you need, and choose your heating/cooling systems, travel gear protections, special track pad variations and more.

Sustainable, powerful engines

Tier 4 engines deliver plenty of power with outstanding sustainability. An exhaust after-treatment system reduces particulate matter, sulfur oxides and dangerous NOx, and easy servicing of emissions components.

Diagnostics to help improve productivity

To improve productivity and limit downtime, you need accurate, reliable machine data. The exca-vator’s newly revamped monitoring system helps you dial in efficient machine movement, quickly identify opportunities to improve productivity, and troubleshoot any issues quickly.

Critical data to help boost efficiency

A built-in payload meter helps you optimize the efficiency of your truck traffic flow and your fleet. Knowing just how much load is in the bucket versus your trucks’ capacity gives you data you need to calculate optimal loading times and truck passes for maximum productivity.

Tier 4 Engine:

Model Komatsu SDA16V160E-3
Type 4-cycle, water-cooled, direct injection
Aspiration Turbocharged and aftercooled
Number of cylinders 16
Rated power (SAE 1995/J1349) @ 1 800 rpm 1 400 kW
Governor All-speed, electronic

The integrated engine oil and filter system combining the oil stabilising systems, Reserve and Eliminator oil filter extends the oil change interval up to 1.000 hours. The high capacity Mesabi engine radiators are cooled by a hydraulically driven fan for superior cooling efficiency.

The Engine meets EPA T4 final low emissions level by using Selective Catalytic Reduction and High Pressure Common Rail Injection System.

Hydraulic system

The power train consists of one main drive. One gearbox drives four identical pumps which draw hydraulic oil from an unpressurised hydraulic tank. Open circuit hydraulics provide maximum cooling and filtering efficiency.

Rated flow (total output) 4 140 L/min
Relief valve setting 310 bar
Swing flow rate 1 590 L/min
High pressure in line filters
one per pump located at the valve blocks
200 microns
Full flow return line filters (5 double)
at head of hydraulic tank
10 microns
Case drain return line filters (one double element) 3 microns

The four-circuit system features a load-limiting governor with oil delivery summation to the working circuits and incorporates pressure cut-off control. Hydropilot prioritizes hydraulic flow giving smooth hydraulic response, simple hydraulic system layout, and a reduced number of components. The hydraulic system includes large swing-out vertical airto- oil hydraulic coolers with temperature-regulated hydraulically driven fans.

Automatic centralized lubrication

Two hydraulically powered Lincoln single line automatic lubrication systems are provided as standard, complete with time and volume variable controls. The central lube grease system is supplied from a refillable 200 L barrel. A second, identical system supplies open gear lubricant to the swing ring teeth through a lube pinion. Replenishment of the containers is through the Wiggins connections on the service arm.
