Capacity and adaptability

The PC4000-6 front hydraulic shovel was designed specifically to load Komatsu 730E mining trucks. The machine is self-driven, with 1,200 mm wide tracks, a 22 m³ standard bucket, and an operational weight of 393,000 metric tons.

It has two engine options, version 1 is a powerful 16-cylinder Komatsu SDA16V160 engine, Tier 1 emissions category, 4-stroke, with water cooling, direct injection with a net power at the wheel of 1,400 [kW] 1,875 [hp], with electronic control and low emission levels of motors.

Version 2, is a powerful 16-cylinder Komatsu SSDA16V160E-2 engine, Tier 2 emissions category, 4-stroke, with water cooling, direct injection with a net power output of 1,400 [kW] 1,875 [hp], with electronic control and low emission levels of engines.



Designed to load more tons per hour, has a great excavating power, an easy filling bucket, and a tested work equipment design. All cylinders are mounted under the work equipment for extra protection. The equipment also has a variety of buckets and wear elements to fit all densities and material properties.

Wide and comfortable cab

The wide and comfortable cab is mounted over 18 viscous mounts and has sound insulation. This pressurized cab also has and automatic air conditioning system. The operator’s seat has a pneumatic suspension, electric heating, two-point seatbelt and can be adjusted in several ways. The instructor’s seat also has a two-point seatbelt. The easy-operated joysticks are electro-hydraulically operated. Pedals control the bucket’s clam, tracks, and swing brake. Has all instruments, KOMTRAX Plus, and AM/FM radio with a MP3 compatible CD player. The wipers have two speeds and an intermittent function mode. It also includes a refrigerator and storage compartments. Mirrors are electrically actuated, have a heating system and can be adjusted from the cab. External sun visors in the side windows of the cab and internal blinds for all windows are standard equipment. The left window is also the emergency exit. All windows are green UV-filter tinted. There is a catwalk mounted in front part of the cab.


Heavy-duty type for shovels, H box-type, with a main body and 2 side track frames (frames) with their corresponding track sets. The main body has a transfer swing ring and a triple bearing system for swing operations. That main body is connected with each side frame through 62 high-torque bolts. Each frame has a track set of 49, 1,200 mm wide cast steel track shoes with a cutting-edge induction hardening treatment, 7 track rollers (side-by-side) and 3 carrier rollers, a drive sprocket, an idler, and tensioning cylinders with automatic hydraulic adjustments.

It has a hydraulic-type service brake system and a oil-bath multiple-disc-type parking brake system. Maximum travel speed of 2.1km/hr at sea level.

Hydraulic system

The system features a load-limiting governor with full oil supply for the working circuits, incorporates pressure cut-off control, Hydropilot prioritization and hydraulic flow providing smooth hydraulic response, simple hydraulic system layout, and a reduced number of components.

Komatsu monitoring system, KOMTRAX Plus™

The KOMTRAX Plus™ system allows the machine to monitor the status of main components, remotely evaluating their condition and operation. This system was designed to reduce repairing costs and to keep an ideal availability by preventing unscheduled downtimes.

In summary, the clearest advantage of this system is that, by using it appropriately, a proper operation and maintenance can be achieved, maximizing its performance and extending its service life.
