Stable Design

Low mounted heavy-duty power train components ensure a stable machine.

Proven Reliability

The 994F power train has proven itself with the most reliable and durable components in the industry for the lowest operating cost-per-ton.

Torque

Torque is developed at the wheel, generating less stress and wear on the axle shafts.

Axles

The front axle is fixed, and the rear axle oscillates ±10°, which allows either rear wheel to rise or fall 677 mm (26.7 in) while all wheels remain on the ground for maximum stability, greater traction and a more comfortable ride.

Differentials

Standard conventional differentials allow one tire to spin faster than the other, keeping developed torque out of the axles.

Axle Shafts

Free-floating axle shafts can be removed independently of the wheels and planetaries for quick and easy servicing.

Robust Structures

The 994F front loader frame features robust structural components for outstanding durability in the toughest loading conditions. The frame is the backbone of the 994F's durability and is specifically designed and manufactured to withstand the higher forces required by the machine's increased payload rating.

Frame

The box-section rear frame, articulation hitch and four-plate loader tower are designed to resist torsional shocks, twisting forces and stresses generated during the loading cycle while protecting driveline and hydraulic system components.

Z-bar Loader Linkage

Proven Z-bar loader linkage geometry delivers maximum productivity. Fewer pivot point and moving parts are designed to reduce maintenance costs.

Lift Arms

The 994F's solid steel lift arms absorb high stresses generated during loading without sacrificing strength or durability. The linkage design provides an excellent view of the bucket edges, corners, and work area, allowing the operator to focus on productivity. The cross sectional area of the lift arms has been increased in several areas to improve durability.

Hydraulic System

Completely enclosed hydraulic system uses separate circuits for lift and tilt, steering and brake control. Separate circuits provide increased cooling and elimination of cross-contamination, resulting in less downtime and greater productivity.

Lift and Tilt System

Three dedicated fixed displacement piston pumps and a fourth electronically controlled variable displacement piston pump deliver high reliability, efficiency and performance to the lift and tilt system. The variable displacement pump is only activated when additional hydraulic speed is needed.

Production

VIMS system collects the information a manager needs to determine equipment usage, future machine requirements, personnel performance, and productivity levels. Payload information can also be used as an accounting tool, an indicator of cycle time efficiency and truck over loading or under loading.

Integrated System Monitoring

Sensors located throughout the machine systems enable VIMS system to quickly exchange and monitor information from all machine systems for efficient, high performance operation.

Advanced Diagnostics

VIMS system simplifies troubleshooting, reduces downtime and lowers operating costs by identifying abnormal conditions before they cause extensive damage.

Data Access

Monitoring and diagnostic information is stored on-board until it can be downloaded for analysis. Data can be accessed through the message center, transmitted via optional radio and downloaded onto a computer for detailed analysis.

Machine Management

Maintenance and Production personnel can download data and generate reports for better machine management. Data can be used to improve effectiveness of scheduled maintenance programs, maximize component life, improve machine availability, increase production and lower operating costs.

VIMS-PC, the off-board reporting software program, allows service personnel to download a complete record of machine health and productivity data to a laptop computer for diagnosis and analysis. Easy-to-use software enables service technicians and mine management to generate health and payload reports for more effective machine management.

VIMS Supervisor

On sites with multiple VIMS machines and where VIMS-PC is used to download all data, the use of VIMS Supervisor can aid in quick analysis of VIMS data. VIMS Supervisor can generate Health and Production report summaries for a single machine or an entire fleet. VIMS Supervisor is the drill down tool for fleet analysis using an existing “VIMS.mdb” database.

High Productivity

Aggressive Cat bucket designs deliver unmatched productivity in the most demanding applications. 994F buckets have been redesigned for optimal loadability and structural reliability.

Rugged Design

Cat buckets are manufactured using shell-tine construction to resist twisting and distortion. A more aggressive spade edge increases bucket penetration and fill factors and provides better retention of loose material. An integral rock guard helps retain big loads for greater fill factors and optimum truck loading.

Spade Edge Rock Buckets

Spade edge rock buckets with bolt-on segments are designed to penetrate through the pile while leaving a smooth work floor. Shouldered, double-strap adapters allow easy change-out and bolt-on segments extend base edge life.

Serrated Edge Coal Bucket

Serrated edge bucket is recommended for low abrasion material loading where greater penetration is required. It does not use GET, thus eliminating the risk of iron falling into crushers. Replaceable serrated or straight edge is available if needed. Serrated edge is standard for the 36 m3 (47 yd3) coal bucket, but can be added to the smaller buckets upon request.

Bucket Protection

Cat Ground Engaging Tools (G.E.T.) provide superior bucket protection for long life in the most punishing conditions. Built to absorb shock, impact, and abrasion, G.E.T. work and wear as a system to boost productivity and lower costs.

Tips

Tips extend bucket life in high wear applications.

Sidebar Protectors

Protects bucket corner and sides from wear in abrasive materials. Pin-on sidebars are reversible to extend wear life.

Edge Protectors
