Cat 920K wheel loader puts control back in operators’ hands

Caterpillar has released its latest compact wheel loader, the 920K with 99hp and a range of product enhancements such as a more fuel-efficient engine and multiple adjustable settings in the cab for a more controlled operation.

Under the bonnet, the 920K’s Cat C4.4 engine meets U.S. Tier 3 or EU Stage IIIA equivalent emission level and is designed for fuel efficiency. The C4.4 allows operators to choose between two power modes: Eco or Standard.

In Eco mode, the engine delivers enhanced fuel economy by operating at a lower maximum engine speed (1925rpm). Standard mode allows the engine to operate at speeds of up to 2350rpm for increased 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. The system adds power when the machine senses high demands, such as climbing grades.

Other 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.

The 920K’s deluxe cab features two side-entry doors, an 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 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.

A rearview camera is available as an option with an in-cab monitor for enhanced rear visibility. Available ride-control uses the loader cylinders to dampen travel bounce for a smoother ride for the operator and better material retention.

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.

A ground-speed (or creeper) control is also available and managed via a dial on the right console that permits control of ground speed independent 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 adjusts the speed of the transmission’s change between forward and reverse travel to suit application needs. Rim-pull control, which offers three settings—60, 80, and 100 percent, allows operators to modulate power to the wheels as ground conditions or applications vary, reducing wheel spin for optimum traction.

The return-to-dig system allows operators to automatically reposition the loader linkage for the next cycle by simply 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. Both systems are adjustable with the push of a button in the cab.

A bucket-float function allows the work tool to follow ground contour for a smooth finish.

Caterpillar said the 920K is designed for high tipping loads with an optimised Z-bar loader linkage which Caterpillar said provides the parallel-lift capability of IT (Integrated Tool Carrier) linkage, as well as the breakout force and aggressive digging capability of conventional Z-bar linkage.

Featuring quick-coupler options and screw-to-connect fittings, the 920K can efficiently handle a range of work tools. The IT coupler is compatible with legacy Cat work tools and works with a range of attachments, including Cat Performance Series buckets, pallet forks, snow blowers and brooms.

Operators can configure the 920K’s hydraulic system to accommodate a variety of hydro-mechanical work tools, and a third-valve auxiliary system features proportional control with a roller switch in the joystick.

The 920K wheel loader offers Cat’s Product Link telematics system as an option at first, but will eventually offer it as a standard feature.

Product Link provides operators with a constant stream of wireless information via the online VisionLink interface. An optional security keypad allows password-protected engine starts to help protect the machine against unauthorised access.
