Implement Controls
N/A928Hz Wheel Loader
Power Train
Delivers maximum rimpull to the ground and full power to loader hydraulics.
Cat Engine
The Cat C6.6 engine provides cleaner, quieter operation while delivering superior performance and durability. The 111 kW (149) rated net power engine meets all worldwide emissions standards and features: flatter power curve for outstanding response in the working RPM range (1,900 to 2,300), noise reduction technologies for up to 5 dB reduction, and patented ACERT Technology combined with common rail fuel system, smart waste gate turbocharger and crossflow head design for reduced emissions.
Cat Axles
Heavy-duty axles feature hardened gears and bearings for durable performance. Rear axle oscillates up to 12 degrees to help assure four-wheel ground contact for optimum traction and stability. Optional front and rear Limited Slip Differentials enable outstanding traction in poor underfoot conditions.
Cat Transmission
Rugged Cat transmission uses heavy-duty components for durable and reliable operation. The operator can choose between manual shift and two autoshift modes, Performance or Economy. Performance mode provides maximum acceleration while the economy mode increases fuel economy and improves operator comfort.
Hydraulics
System provides high efficiency wtih low effort, precise control.
Proven Design
Time tested hydraulic system provides low effort operation and superior control. Fast loader cycle times help you get more done.
Dual Hydraulic Pumps System
Load-sensing steering pump provides outstanding response during heavy and light duty operations. High output implement pump provides all the hydraulic power required to move loads at all engine speeds.
Ride Control System
The optional Ride Control System provides a comfortable ride and excellent material retention. Nitrogen charged accumulator enables optimum cushioning over uneven terrain for all loads and speeds. The system operates in Automatic - as the loader ground speed exceeds 5 kph (3 mph) the system will activate, below 5 kph (3 mph) the system is off providing maximum lift power.
Loader Linkage
Strong design delivers superior performance.
Z-bar Design
Z-bar design linkage generates excellent breakout force and good rack back angle for better bucket loading and load retention. Lift arms are solid steel, providing superior strength with an excellent front end viewing area. The proven design offers excellent dump clearance and reach for exceptional truck loading performance.
Operator Station
Superior comfort keeps you productive, all day long.
Cab
Experience comfort and convenience in the H-Series cab. The spacious interior and ergonomic controls keep you comfortable throughout the work day. Choose the seat that meets your needs - the standard, fully adjustable seat or the optional Cat Contour seat for added adjustment and air suspension. The two-door design lets you enter and exit from either side of the machine and wide, serrated steps provide stable footing. Both doors lock open 180 degrees and feature sliding glass windows for better communication with workers on the ground. Large flat glass windows provide excellent visibility all around the machine. The rear window features a standard electric defroster.
Controls
Low effort, ergonomic joystick controls provide easy operation of lift and tilt functions. The standard joystick features an integrated directional control switch for added convenience. The operator programmable transmission neutralizer can be set in seconds optimizing brake effort for all applications.
Instrument Panel
The sealed instrument panel with easy to read white faced gauges and indicators keeps the operator informed of system conditions. The large LED readout provides ground speed and other critical information.
Optional Rear View Camera
This work area visual enhancement system uses a closed circuit video monitoring system. Up to three cameras can be mounted on the machine frame. Objects can be viewed on a color LCD monitor in the cab.
