Productivity and power

The PC3000 hydraulic shovel/excavator was designed specifically to work together with Komatsu mining trucks with capacity from 63 t to 144 t. The machine is self-driven, with 800mm wide tracks, a 15 m³ standard bucket for backhoe version and a 16 m³ standard bucket for front shovel version, and an operational weight of 250-261 metric tons.

Equipped with 12-cylinder Komatsu SSA12V159-2 engine, Tier 2 emissions category, 4-stroke, with power system, direct injection with a net power output of 940 [kW] 1,260 [hp], with Electronic control and low emission levels of motors.

Features

Productivity

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

Pressurized cab with integrated FOPS structure, mounted to the main frame through 15 viscous mounts, providing a high level of vibration and noise insulation (75 dB (A) according to ISO 6396). It has air conditioning, heating and defrosting. Electronic monitoring system from the cab - ETM. Operator seat with weight compensator, electrically heated, with vibration dampener, seatbelt, and additional seat for passenger. Cab with high visibility and dark green tinted windows. Joystick-type controls (2) (electric over hydraulic) for a smoother operation, and pedals to control the machine’s movements and the swing brake. The cab includes also electric-heated external rearview mirrors and an AM/FM radio.

Undercarriage

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 frame through 38 high-torque bolts. Each frame has a track set has 46 800 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.

Hydraulic system

The three-circuit system features a load-limiting governor with full oil supply for the working circuits and 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.
