Quality and Reliability

The PC5500-6 hydraulic shovel was designed specifically to load Komatsu mining trucks with capacity from 144 t to 222 t. According to the field’s needs, the shovel can have a diesel engine or electric motor. The machine is self-driven, with 1350mm wide tracks, a 29 m³ bucket, and an operational weight of approx. 533-552 metric tons.

The PC5500-6 has two 12-V cylinders 4-stroke turbocharged air-to-air aftercooled Komatsu SDA12V159E-2 diesel engines. It has a 940 [kW] 1260 [HP] sea level net flywheel power for each engine, and is EPA Tier II certified.

The equipment also includes the Centinel oil control system, reserve oil supply and Eliminator filter system.

Features

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.

Undercarriage

Heavy-duty type for shovels, H box-type, with a main body and 2 side track frames. The main body has a transfer swing ring and a triple bearing system for swing operations. That main body is connected with each side track frame through 80 high-torque bolts. Every track set has 7 track rollers (side-side) and 3 carrier rollers, a drive sprocket, an idler, hydraulically adjusted tensioning cylinders, 1350 mm wide cast steel track shoes with a cutting-edge induction hardening treatment.

Parking brake system and reverse wheel motors.

Maximum travel speed of 2.1 km/hr at sea level.

Hydraulic System

Six (6) hydraulic Rexroth A4V500 model variable axial piston-type main pumps connected to transfer cases provides the machine with the Hydropilot system (an open 4-circuit hydraulic system), for the highest cooling and filtrating efficiency, with a load-limiting governor, pressure cut-off and demand prioritized flow (swing).
