Construction equipment provider Caterpillar’s new 920K Compact Wheel Loader’s features allow operators to tailor machine performance to individual preferences for added operating efficiency, while a choice of auxiliary-hydraulic systems expand the use of work tools for added utility.

With a net power rating of 74 kW, the loader displays product enhancements that contribute to high productivity, versatility, operator convenience and safety, and serviceability.

The 920K’s cab features two side-entry doors, low-effort electro-hydraulic joystick, suspended pedals, a tilt steering wheel, and an air-suspended seat. The joystick controller provides single-lever control of loading functions and 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 liquid crystal display monitor for the standard primary display provides reliable operating information at a glance through 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 reduce travel bounce for a less-fatiguing ride for the operator and improved material retention.

Built-in control features, some of which are only available with the Road and Load Feature Package, enhance operating efficiency and safety.

Modulated inching capability allows the first half of brake-pedal travel to control ground speed regardless of engine speed, providing optimum hydraulic performance at speeds that best match the application. Ground-speed control, managed by a dial on the right console, also permits control of ground speed regardless of engine speed.

The implement-response system allows for three adjustable loader-performance settings, enabling operators to match loader responsiveness to the application. A directional-shift response system, consisting of three settings, adjusts the speed of the transmission’s change between forward and reverse travel – to suit application needs or individual preferences. Rim-pull control, which has three settings, 60%, 80% and 100%, allows operators to modulate power to the wheels as ground conditions or applications vary. This reduces wheel spin for increased traction.

The return-to-dig system allows operators to automatically reposition the loader linkage for the next cycle by moving the joystick to the boom-down detent position. The lift-kickout feature stops the loader arms at a predetermined height when the joystick is in the boom-up detent.

Performance and Fuel Efficiency

The 920K’s Cat C4.4 engine meets US Tier 3 equivalent/EU Stage IIIA equivalent emission level requirements and is designed for fuel efficiency. The C4.4 allows operators to choose between Eco or Standard power modes.

Eco mode allows for enhanced fuel economy of the engine by operating at a lower maximum engine speed of 1 925 rpm. Standard mode allows the engine to operate at speeds to 2 350 rpm, providing more wheel torque and hydraulic power in both transmission ranges for demanding applications.

The 920K also uses an “intelligent” power-management system that balances performance and fuel efficiency. This adds power when the machine senses higher demands, such as climbing grades. On-demand power adjustment results in 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 overheating in hot climates.

The loader is designed for high tipping loads, which enhances stability when handling heavy loads and large work tools.

The 920K can efficiently handle a variety of work tools, increasing versatility. The 920K’s hydraulic system can also be configured for multiple valves to accommodate a variety of hydromechanical work tools, and a third-valve auxiliary system features proportional control with a roller switch in the joystick.
