In the harsh environment of a millyard application, you need a wheel loader designed for the job.
In the harsh environment of a millyard application, you need a wheel loader designed for the job. Since 1963, the Cat® Large Wheel Loaders have helped more customers than any other manufacturer’s model in this wheel loader size class. Read on to learn more about how Cat log loaders deliver sustainable productivity, fuel efficiency, serviceability, reliability and versatility.

Purpose Built Linkage
The 990H log loader arrangement includes a purpose built linkage designed to optimize machine performance for the log loading application. Larger lift and tilt cylinders with extra counterweight allow the machine to unload an on-highway truck with a single pass. Third valve hydraulics allow for top clamp operation to secure the log load.
The optional Ride Control attachment cushions the lift arms when operating with a log load, improving operator comfort and productivity.

Impeller Clutch Torque Converter (ICTC) and Rimpull Control System
ICTC combined with the RCS allows the operator maximum flexibility in modulating rimpull.
Left brake pedal modulates rimpull from 100 to 25 percent for reduced tire slippage and wear. After 25 percent is achieved, further pedal travel applies the brakes.
RCS reduces the potential for wheel slippage without reducing the hydraulic efficiency. An in-cab switch allows the operator to set a percentage of maximum rimpull to meet operating conditions. Four settings are available, and operators can set rimpull at 60, 70, 80 or 90 percent.
Torque Converter Lock-Up Clutch
A lock-up clutch torque converter provides direct drive efficiency which translates into improved fuel economy in a millyard application.
Maximizing uptime, long life – it’s what you expect from your Cat Wheel LoaderLearn More
Cat Large Wheel Loader structures are designed with superior durability for multiple machine rebuilds by combining the use of robotic welding and castings in critical high stress areas. More than 80 percent of the machine structure is robotically welded to provide highly consistent welds and increased strength. Castings are also used in several areas to increase strength by helping spread the loads and reduce the number of parts.
Front Frame and Rear Frame
Highly engineered and a field proven combination, Cat Large Wheel Loaders use high strength plates and castings which distribute loads and increase structural robustness. A key differentiator from other manufactures machines is the box section rear frame and box section loader tower. The box section absorbs tensional forces generated in a loading cycle, maintaining alignment for hitch pins and driveline. The box shaped loader tower resists shock and torsional loads, maintaining hitch and loader linkage pin alignment, maximizing pin life.
Axle-Shaft, Oil Disc Brakes
These brakes are adjustment free, fully hydraulic and completely sealed. Disc face grooves provide cooling even when brakes are applied for a longer component life.
Location of brakes allow for improved serviceability. The axle shaft brake design allows for brake service while leaving the final drive intact.
Axle-shaft brakes require less force by operating on the low torque side of the axle. Combined with improved axle oil circulation for increased cooling, the oil-enclosed, multiple disc brake design improves durability.

Entry and Exit
Getting on and off the machine is one of the leading causes of injury on a job site. Cat Large Wheel Loaders have a number of features to ensure your operator gets safely on and off the machine. Cat Large Wheel Loaders include primary and secondary stairwell exits, punch stamped tread plates, ground level nighttime stairwell light switch, full perimeter railings on upper platforms, side platform emergency egress and toe kicks and optional roading fenders.
With the new optional rearview camera, visibility is greatly enhanced. The camera is located in a pocket on the grill to protect it from damage and the elements. The camera can be set to activate only when the transmission is in reverse to help eliminate distractions in the cab, especially when in dark environments.
Cat Large Wheel Loaders offer a number of standard and optional features to enhance job site visibility. Standard and optional features include long life LED lights, articulated wiper/washer system with intermittent features, optional rear vision camera, optional high intensity discharge lights, optional warning beacon and optional turn signals. The rearview camera display can accommodate up to three cameras which can be configured in a variety of ways by your local Cat dealer. Object detection kits are also available through your local Cat dealer.

Swing out doors on both sides of the engine compartment provide easy access to the engine oil dipstick and filler spout, S∙O∙SSM ports, fuel filters air conditioner compressor, engine oil filters, alternators, starting receptacle, air filter service indicator, cooler fill and ether starting aid. There are also ground level viewable sight gauges on all major systems and centralized remote pressure taps.
Shutdown and Lockout Features
An electrical disconnect switch and hydraulic lockout switch allow service technicians to perform maintenance while the machine stays static. Other shutdown or lockout devices include ground level engine shutdown and ground level steering hitch lock lever.

Forks and Buckets
Millyard and Logging Forks are designed to move wood in the millyard. Woodchip Buckets are designed with performance characteristics to bring productivity and fuel efficiency to load-and-carry work in the yard.
A single top clamp closes down between the tines, allowing individual logs to be picked and placed with ease. An open, high visibility design allows operators to see the job at hand, work faster and more efficiently.
Dual top clamps close down to the tine tips, their curvature maximizes carry capacity. Built to match the task of unloading trucks. An open, high visibility design allows operators to see the job at hand, work faster and more efficiently.
Extra capacity and loading characteristics make this bucket style perfect for handling woodchips. Available in direct pin on models or for use with the Cat Quick Coupler System.
Cat Full Width Forks
Dual top clamps are connected to allow maximum capacity while still closing between the tines allowing partial loads to be handled.
