TEREX TXC 420LC-1 CRAWLER EXCAVATOR

Technical Description

The Terex TXC 420LC-1 is a large-scale hydraulic excavator engineered for demanding earthmoving and material handling applications. This robust machine features an operating weight of 90,830 pounds with exceptional digging capabilities, offering maximum digging depths ranging from 25.4 to 27.8 feet depending on boom/stick configuration. The excavator delivers impressive reach specifications, with maximum ground-level reach extending to 39.6 feet and cutting heights up to 37.8 feet, making it suitable for deep excavation projects and high-lift operations. Powered by a turbocharged DE12TIS engine producing 281 net horsepower at 2,000 rpm with 853 foot-pounds of torque, the TXC 420LC-1 combines power with efficiency. The hydraulic system operates at 4,550 psi relief pressure with a pump flow capacity of 166.5 gallons per minute, enabling smooth and responsive bucket control. The machine accommodates multiple bucket configurations ranging from 1.9 to 2.9 cubic yards, providing operational flexibility for various material types. Mobility is enhanced by a maximum travel speed of 3.5 mph with ground pressure of only 10.4 psi, minimizing ground disturbance on sensitive terrain. The swing mechanism rotates at 9.5 rpm, facilitating efficient material placement. Structural stability is ensured through a 12.1-foot tail swing radius and an 11-foot track width, while the undercarriage features 50 shoes per side with durable 23.7-inch shoe sizing. The machine's 145.3-gallon fuel capacity supports extended operation cycles, making it an economical choice for continuous production environments requiring substantial excavation force and reach capabilities.
