Cat® 994H Wheel Loader Offers Four Lift Configurations

For Release Worldwide: August 2012

Release Number: 294PR12

The 994H, largest of the Cat® wheel loader line, features four loader linkage configurations and a range of buckets to tailor the machine to the job. While optimally matched to Cat 785, 789 and 793 mining trucks, the 994H has the design flexibility, capacity and durability to deliver reliable, low-cost production in any operation. Engineered to ensure operator safety, comfort and convenience, the fuel efficient 994H, with 1,463 net horsepower (1 092 kW) and an operating weight of 431,000 pounds (195 500 kg), features Caterpillar's Rimpull Control System, Positive Flow Control hydraulics and Vital Information Management System.

Lift configurations for the 994H include standard, high lift, extended high lift and super high lift, providing dump clearances at maximum lift that range from 19.2 feet (5 578 mm) to 23.3 feet (7 080 mm). Bucket choices include heavy-duty rock, high-abrasion rock and coal— available in narrow and wide widths to suit the application—and ranging in capacity from 19.5 to 47 cubic yards (15 to 36 m³).

To ensure durability that will sustain multiple life cycles, the 994H uses solid-steel lift arms that work though a powerful Z-bar linkage, which features a greased pin design and an automatic lubrication system. The 994H rear frame is a full-box-section fabrication designed to resist torsional shock and twisting forces, and the machine's cast axle-pivot mounting areas disperse stress loads for added overall durability.

For fuel efficient operation, the Cat 3516B HD engine works through a Cat planetary powershift transmission specifically designed for mining applications. An integral Impeller Clutch Torque Converter and Rimpull Control System allow the operator to precisely adjust power at the wheels to specific loading conditions by modulating rimpull from 100 to 25 percent, reducing potential for tire slippage without diminishing hydraulic capacity.

The 994H Positive Flow Control (PFC) implement hydraulic system uses four, electronically controlled, variable-displacement pumps, delivering up to 386 gpm (1 460 L/min) at a main-relief pressure of 4,750 psi (32 800 kPa), assuring fast, consistent response, as well as fuel economy and low heat generation. The PFC system also integrates concurrent valve control, providing precise, proportional command of loading functions with electro-hydraulic loader controls, electronically controlled cylinder stops and automatic kickouts set from the cab.

The Steering and Transmission Integrated Control System (STIC™) combines control of travel direction, steering and gear selection in a single controller, and the spacious, pressurized cab features automatic climate control and a quiet, 71 dB(A) sound rating. The 994H also features a powered access ladder and reduced stairs angles for easy access and egress from the operator station. For enhanced operator awareness of the area around the loader, the Cat Detect Vision rear vision camera system is standard, and Cat Detect Object Detection is available. Object Detection includes radars that detect objects around the machine and notify the operator of these potential hazards.

Integral with the 994H Vital Information Management System (VIMS™), which allows real- time assessment of machine performance, is the Payload Control System that enables on-the-go weighing, payload recordkeeping and analysis of parameters such as utilization, cycle time and fuel usage. In addition, the available Cat MineStar™ System provides a suite of integrated mine operation and equipment management technologies that can enhance 994H operation and maintenance.
