Caterpillar unveils lastest 988K XE wheel loader

Caterpillar has released the new Cat 988K XE wheel loader with a high-efficiency electric drive system for increased fuel efficiency and lower total cost of ownership.

The 988K XE joins the 988K and the recently launched 986K wheel loaders, delivering high-production in all loading applications.

The new loader features switched reluctance (SR) technology and leverages more than 15 years of Cat electric drive experience and more than 4 years of stringent testing in a range of applications for proven reliability in the field. The C18 ACERT engine, mechanical dropbox, driveline and axles from the 988K remain in the electric drive machine for consistent, trouble-free operation.

High efficiency and productivity

Offering increased truck loading and load-and-carry capacity, the 988K XE increases efficiency by 25 per cent overall and by up to 49 per cent in face-loading applications compared to the 988K. This reduces costs and helps operations reduce greenhouse gas emissions and their overall carbon footprint. It also provides higher productivity in load-and-carry applications.

The 988K XE loader offers a range of bucket capacities from 6.2-17 yd3 (4.7-13 m3). Rated standard and high lift payload for the loader reaches 12.5 tons (11.3 tonnes) when working with face material and 16 tons (14.5 tonnes) with loose material. Advansys Series Ground Engaging Tools (GET) protect bucket components and reduce operating costs, so operations can get the most out of machine performance.

The standard 988K XE wheel loader offers 3-pass loading of the 42.6-ton (38.6-tonne) Cat 770G and 4-pass loading of the 51-ton (46.3-tonne) Cat 772. Its high-lift configuration delivers 5-pass loading of the 61-ton (55.3-tonne) Cat 773G and 6-pass loading of the 70.5-ton (64-tonne) Cat 775G.

Extended service, lower ownership costs

Cat electric drive technology in the 988K XE lowers overall maintenance costs, while increasing engine life expectancy. Offering extended oil change intervals of 2,000 hours, the electric drive wheel loader uses 40 per cent less powertrain oil.

The durable SR drive motor, generator and inverter are built to last through the second engine life with minimum maintenance. Additionally, the efficient electric drive design increases engine life by up to 3,500 hours, extending time between powertrain rebuilds.

To assist with electric drive rebuilds, Caterpillar offers customers service training material, backed by customer support from the Cat dealer network. Remanufactured drive motors, generators and inverters will also be available to reduce rebuild cost.

Similar operation, greater productivity

Slight changes inside the cab of the new 988K XE provide operators with the familiar functions and feel of the 988K. Operators will experience improved handling smoothness and ease of operation. The new loader offers a single speed range, so the machine efficiently operates without the need for gear shifting. New virtual gears help to control machine ground speed and deliver smooth direction shifts.

The standard Cat Product Link offers remote data monitoring through VisionLink, so key personnel can stay informed of critical machine operating data.  Fuel usage, payload summaries, scheduled service reminders, fault code alerts and various productivity reports are available to help improve machine management.  Additionally, the onboard Vital Information Management System (VIMS) provides the operator with operating data such as real-time fuel consumption and fuel efficiency via an interactive touch screen display.

The 988K XE loader is equipped with a host of technology solutions to increase operating efficiency and machine uptime. Cat Production Measurement (CPM) brings payload weighing to the cab, so operators can work more productively and deliver accurate loads with confidence. CPM offers advanced weighing modes, which assist with payload accuracy and increase loading cycle speed.

Optional Tire Pressure Monitoring System (TPMS) is a fully integrated Cat feature, which enables operators to monitor tire inflation. Available through the VIMS display, the operator can quickly view each tire’s pressure and take action when needed to reduce wear and increase service life.

Operators can safely access via left- or right-hand stairs built at a reduced 45-degree angle and maintain three points of contact at all times. The STIC steer armrest easily folds up, allowing the operator to quickly enter the cab. Isolation cab mounts and an air-suspension seat reduce vibration transmitted to the operator for increased comfort, while the enclosed pressurised structure reduces operator sound levels. The automatic, in-cab temperature control system maintains operator comfort even in extreme temperatures.
