Caterpillar, a leading manufacturer of construction equipment, has launched its new 920K compact wheel loader, with a net-power rating of 74 kW (99 horsepower), reflects significant product enhancements that contribute to high productivity, versatility, operator convenience/safety, and serviceability.
New features allow operators to tailor machine performance to individual preferences for added operating efficiency, and a choice of auxiliary-hydraulic systems expand the use of work tools for added utility.
The 920K’s Cat C4.4 engine meets U.S. Tier 3 equivalent/EU Stage IIIA equivalent emission level and is designed for fuel efficiency. The C4.4 allows operators to choose between power modes: Eco or Standard. In Eco mode, the engine delivers enhanced fuel economy by operating at a lower maximum engine speed (1,925 rpm). Standard mode allows the engine to operate at speeds to 2,350 rpm, providing more wheel torque and more hydraulic power in both transmission ranges for demanding applications.
The 920K also incorporates an “intelligent” power-management system, which balances performance and fuel efficiency, adding power when the machine senses high demands, such as climbing grades. On-demand power adjustment means optimum productivity and hydraulic speed under load. Fuel-saving features include an on-demand cooling fan that provides fast machine warm-up and lower sound levels, while preventing over-heating in hot climates.
Efficient operator environment
The 920K’s deluxe cab features two side-entry doors, low-effort electro-hydraulic joystick, suspended pedals, tilt steering wheel, and an air-suspended seat. The joystick controller provides single-lever control of loading functions and also integrates transmission and differential-lock controls. The joystick also accommodates controls for two- and three- hydraulic systems, including proportional control of auxiliary circuits.
A large LCD monitor for the standard primary display provides pertinent operating information at a glance via an easy-to-read back-lit screen, and gauges in the display cluster show fluid levels and component temperatures. An optional rearview camera with an in-cab monitor enhances rear visibility. Available ride-control uses the loader cylinders to dampen travel bounce for a smoother, less-fatiguing ride for the operator and improved material retention.
Built-in control features (some available only with the Road and Load Feature Package) significantly enhance operating efficiency and safety. Modulated inching capability allows using the first half of brake-pedal travel to control ground speed independent of engine speed, providing optimum hydraulic performance at speeds that best match the application. Ground-speed (“creeper”) control, managed by a dial on the right console, also permits control of ground speed independent of engine speed.
