HYUNDAI ROBEX 170W-7A CRAWLER EXCAVATOR

Technical Description

The Hyundai ROBEX 170W-7A is a wheeled excavator engineered for versatile mobile construction applications. Powered by a turbocharged D04FD-TAA engine producing 126 gross horsepower (94 kW) and 116 net horsepower at 2,000 RPM, this machine delivers robust digging force through a dual variable displacement piston hydraulic pump system rated at 88.8 gallons per minute and 4,690 PSI relief pressure. The excavator operates on a hydrostatic transmission with four forward and reverse speeds, achieving a maximum travel velocity of 18.7 mph with impressive drawbar pull of 24,250.9 pounds. The machine features a mono boom measuring 5.1 meters (16'9") with three interchangeable arm configurations—2.2 meters, 2.6 meters, and 3.1 meters—providing maximum reach capabilities from 27.9 to 30.4 feet along ground. Maximum digging depths range from 17.8 to 20.8 feet depending on arm selection, with cutting heights reaching 30.25 feet. The excavator accommodates bucket capacities from 0.6 to 1.4 cubic yards, offering flexibility for diverse earthmoving tasks. Operating at 38,051.8 pounds, the machine maintains a tail swing radius of 8.2 feet and compresses to 10.4 feet for transport. The cab design prioritizes operator comfort with an air suspension seat, viscous mounting system, large sunroof, and adjustable controls. Advanced features include an automatic swing brake, boom and arm holding systems, one-touch deceleration, and a centralized LCD monitoring system with self-diagnostic capabilities. The 24-volt electrical system and 68.7-gallon fuel capacity support extended operation cycles, while comprehensive cooling and hydraulic fluid management systems ensure reliable performance in demanding construction environments.
