CATERPILLAR 336E H CRAWLER EXCAVATOR

Technical Description

The Caterpillar 336E H is a hydraulic hybrid excavator engineered for demanding earthmoving and material handling applications. Powered by a Cat C9.3 engine delivering 308 net horsepower and 230 kilowatts, this machine weighs 82,000 pounds and features advanced hybrid technology that recovers energy during operation. The excavator utilizes three power modes—high power, standard power, and economy—along with on-demand engine power and idle shutdown capabilities to optimize fuel consumption, achieving up to 25 percent fuel savings compared to standard 336E models. The 336E H accommodates two boom and stick configurations to suit varied job requirements. Option one features a 21-foot-4-inch reach boom paired with a 12-foot-10-inch stick, delivering a maximum cutting height of 35.3 feet and digging depth of 26.9 feet. Option two combines the same boom with a 10-foot-6-inch stick, achieving a 33.9-foot cutting height and 24.6-foot digging depth. Both configurations maintain 38.5 feet and 36.2 feet maximum reach along ground level, respectively. The hydraulic system operates at a maximum relief pressure of 5,076 psi with a 74-gallon-per-minute pump flow capacity. The excavator accommodates bucket sizes ranging from 1.3 to 3.4 cubic yards, with a reference capacity of 1.6 cubic yards. The swing mechanism rotates at 9 rpm, while the undercarriage produces 67,443 pounds of drawbar pull with a maximum travel speed of 3.2 mph. Track shoes measure 31.5 inches wide, and the unit's tail swing radius spans 11.5 feet, making it suitable for confined jobsites.
