Robust and Stable Design: That is how the new Komatsu 4800XPC can be likened to when it comes to versatility and ease with it can execute work. From its ultra-rugged lower works to their spacious machinery decks and classic, twin-leg style handle-and-dipper configuration, the P&H 4800 XPC electric rope shovel is part of the family of shovels that have earned a place as a preferred loading tool for high-production, high-efficiency mine operations. Its position will even be more consolidated.

P&H electric shovels are designed and built to help mines move more material at a lower cost per ton. Equipped with a nominal payload of 122.5 metric tonnes (mt), dipper capacity of 65.7 to 70.3 m3 (86 to 92 yd.3), adaptive controls technology, direct-drive crowd with integral fleeting sheave to help eliminate boom jacking and optimized boom design for improved maintenance access, the loading beast will take its rightful place and give Komatsu a huge edge over its competitors. The P&H 4800 is so good that it can easily load in three-passes a 360mt ultra-class haul truck. The 4800XPC, when compared to its predecessor, the 4100XPC, offers up to 20% increase in production and up to 10% decrease in cost per ton.

Specifications

Working on a range of height of cut of up to 19m within a radius of 24m, the 4800XPC also offers a maximum dump reach of 19.4m, with a dumping height of 10.8m. The machine offers an operator eye level of 10.1m, tail swing radius of 16.2m and floor level radius of 16.2m. The machine comes in 15.2m in length, a width of 15.0m, and a height of 14.7m (over the gantry)

Mechanical Versatility

The digging machine readily has a full suite of service products and consumables available, including wire rope, GET, crawler shoes and more with mechanical upgrades, repair and rebuild services are available worldwide. According to Komatsu, “Our focus on modular component design means more efficient maintenance and upgradability. This emphasis on ease-of-maintenance, combined with the traditionally rugged P&H mechanical systems and increasingly smart, fast control systems, translates into some of the most reliable, productive loading machines in the mining industry today”

The direct-drive crowd with integral fleeting sheave on the machine reduces maintenance costs and helps eliminate boom jacking whilst optimized boom design with stabilized handle geometry improves dipper manoeuvrability and maintenance access. The enhanced ring gear resists fatigue and accommodates increased payload. It comes with:

  • A wide twin-leg handle for stability through the dig cycle
  • A geometry optimized for fatigue resistance in shock and high-load conditions
  • Maximized cutting forces for improved fill factors and cycle times

Komatsu describes the machine as a reliable machine of high availability which can consistently achieve over 90% mechanical availability with proven mining duty motors and gearboxes for extended component lives and a structural design that uses high-strength, low-alloy steels for improved fatigue lives. It has rugged components that includes dual-hoist motors for balanced and evenly distributed loads, DELTA drive for improved shoe-to-tumbler engagement, and planetary transmissions with proven long life on swing and propel (over 20 million hours logged).

The digging unit comes with highly precise motor controls due to the existence of rugged centurion-based compact-design ABB drives, direct torque control with the best dynamic performance, AC drives that are compact, air-cooled, and modular, maintenance-friendly modules that are easy to replace, monitored and controlled neural network of over 500 I/O nodes, using fast, high-capacity Profibus fiber-optic cable network and optimized shovel performance for maximum production rates.

The PreVail remote health management (RHM) system provides timely and efficient machine health and performance data. The PreVail RHM system taps into the powerful communication, command, and control capabilities of the shovel’s electrical control system, transforming the data into valuable knowledge, including KPI (key performance indicator) dashboards, graphical analysis tools, predictive modeling, and reporting tools.

Efficiency and Operator Comfort

The rresponsive control system offers the operator confidence throughout the digging cycles. The clean graphical user interface displays shovel systems operation and health information whilst the high visibility enabled and efficient sight lines with refined ergonomics (adjustable heated seat, massage controls, adjustable lumbar support, and two-position footrest) improve operator effectiveness and reduce fatigue. So well ergonomically designed is the operator cabin that loading control joysticks, brake and propel transfer functions are easily at operator’s fingertips, and dipper trip and signal horn trigger switches reduce operator fatigue and repetitive strains.

Filtered air comes through the house pressurization system for cooling and dust repression. The P&H 4800XPC just like its family members features hand-operated hoist, crowd, swing and propel control joysticks feature thumb-actuated auxiliary switches for siren, dipper trip functions. There is also convenient access to shovel control buttons, switches mounted to the left, right consoles flanking operator. Safety of the operator is enhanced by the modular counterweight and boarding stairs which are also easy to assemble and disassemble.

The included Mine Air Systems (MAS) climate control system provides air conditioning, heating, air filtration, and pressurization for your electric mining shovel. The design takes into account careful thought on modular design for unmatched change-out speed and convenience, unique weather-sealed roof-plate eliminates dust and water leaks into the cab and electrical room, stainless steel construction, designed specifically for ozone friendly R-407C refrigerant, high-efficiency air filters to suit each application,  industrial-sized extra-efficient filter/pressuriser with air pre-cleaner, smooth and quiet scroll-technology compressor and enhanced dipper design which provides improved bank penetration and higher payload-to-weight ratio.

There is no shadow of a doubt that the

Komatsu P&H4800XPC is

a beast in the

mining load and haul fraternity and it has been unleashed.
