Caterpillar boosts lifting capacity with new compact wheel loader

The new Caterpillar 903D compact wheel loader boasts a 25 per cent boost in lifting capacity and travel speed when compared to its predecessor.

The compact wheel loader is also available with several new optional features, such as creep control, throttle lock and work tool electrical harness.

The 903D operator’s station features an ergonomic design with a new multi-function joystick that provides fingertip control of the standard third-function hydraulic system. Whether lifting light material into a hopper or loading heavy pallets onto a truck, the choice of standard-lift or high-lift boom arms increase the 903D’s ability to work with buckets ranging in capacity from 0.6 to 1.0 cubic metres, forks or a selection of powered and non-powered work tools.

The compact wheel loader powertrain uses a 40 hp, Tier 4 Final Cat C2.4 engine and a hydrostatic transmission to reach 20 km/h.

The 903D also features a standard auxiliary (third-function) hydraulic system that delivers a flow of up to 52 litres per minute at pressures to 3,481 psi.

To facilitate the use of an expanded range of work tools, the compact wheel loader is equipped with a standard universal coupler, with an optional electrically activated coupler available for switching attachments from the cab. Auxiliary hydraulic lines with quick connectors are standard, and continuous-flow allows powered tools to be easily controlled.

To further enhance the 903D’s versatility and productivity, new optional features allow ground speed (creep control) and engine speed (throttle lock) to be independently controlled. As well, an optional work-tool electrical harness allows use of attachments that have electrically operated functions.

For operator convenience, the 903D’s new multi-function joystick provides controls for directional changes, third-function hydraulics, differential locks and continuous hydraulic flow. The operator’s station has increased leg room, improved pedal positioning, easier entry or exit, a suspension seat and tilt steering wheel.

The design of the compact wheel loader results in minimal engine overhang, providing enhanced visibility to the rear and corners. Both enclosed cab as well as canopy options are available, and an optional heavy-duty 90-amp alternator can be used to support the climate-control system.

To facilitate routine maintenance, the 903D’s fully opening rear hood provides access to the engine compartment, which features side-by-side coolers and transparent fuel/water separator.

Options include an engine air pre-cleaner and radiator screen for use in high debris applications. New rear tie down locations under the machine allow for easier transport, and a new engine oil fill location allows for easier access.
