Technical Description

The Caterpillar 938K is a versatile wheel loader featuring a Cat C7.1 ACERT engine delivering a net power of 169 hp (126 kW) at 1600 rpm and a gross power rating of 175 hp (131 kW). It offers a bucket capacity range from 3.3 to 6.5 cubic yards (2 to 5 cubic meters), optimized for high productivity with an 8.5-gallon (30 L) cooling system and a hydraulic system flow capacity of 50 gal/min (189 L/min) operating at a relief valve setting of 4061 psi. The loader’s maximum bucket pin height reaches 13 feet (4 meters), with an overall lift clearance of 9.3 feet (3 meters) at a 45-degree dump angle, and a digging depth of 3.9 inches (8 cm). Its operating weight is approximately 35,104 lbs (15,923 kg), with an overall length of 25.1 feet (8 meters) and a wheelbase of 10 feet (3 meters). The 938K’s hydraulic cycle time is 9.7 seconds, including 6.2 seconds to raise and 1.5 seconds to dump the bucket. It features a robust Z-bar linkage for efficient load handling and parallelism, complemented by a high-torque low-speed engine that promotes fuel efficiency. The machine supports a maximum steering articulation and angle of 40 degrees, aided by a steering system with a maximum working pressure of 3500 psi. Transmission includes four forward gears with a top speed of 25 mph (40 kph) in both forward and reverse. Safety is enhanced with ROPS and FOPS-certified cabins conforming to SAE and ISO standards for operator protection.
