Technical Description
The Caterpillar 994F is a heavy-duty wheel loader engineered for high productivity and durability in mining and large-scale material handling operations. It features a Cat 3516B HD EUI engine delivering a gross power of 1,577 hp (1,176 kW) and net power around 1,463 hp (1,091 kW), providing robust performance at 1,600 rpm. The machine's operating weight is approximately 427,200 lbs (193,777 kg), with a rated payload capacity of up to 76,000 lbs (34,473 kg) in standard lift configuration.
The 994F is equipped with a fixed front axle and a trunnion rear axle that offers 10° front oscillation and 20° rear axle oscillation, ensuring stability and ground adaptability. Its braking system complies with SAE J1473 and ISO 3450 standards for safety and reliability. The bucket delivers a maximum breakout force of 222,336 lbs (100,851 kg) and offers a heaped capacity up to 24.9 cu yd (19 m³) with a bucket width of 18.6 ft (5 m), designed for efficient loading matched to large Cat trucks like the 785C, 789C, and 793C.
Hydraulic operations utilize a high-flow piston pump system delivering 362 gallons per minute, enabling lift cycle times of 11.3 seconds and dump cycle times of 3.1 seconds. The lift/tilt system uses double-acting cylinders with a relief valve set at 4,750 psi, providing precise bucket control. Steering employs a closed-circuit, load-sensing piston pump system with a relief setting of 4,500 psi for smooth maneuverability. The machine measures 64.1 ft (20 m) in overall length with a 21 ft (6 m) wheelbase and has a maximum hinge pin height of 26.9 ft (8 m), optimizing dump clearance and operational reach. Fuel capacity is 1,012.6 gallons, supporting extended operations. The cab is built to ROPS/FOPS standards, ensuring operator safety and comfort.
