The Doosan DX350LC-3 excavator features a 281-hp engine, a 77,603-lb operating weight and a 41,667-lb arm digging force. Built for the most rugged conditions, this excavator features significant power and performance increases to go along with its interim Tier Ⅳ status: Swing torque, digging force and lifting capacity have all increased.Upgrades to the cooling system include two variable-speed hydraulic fans, which allow the engine and oil cooling systems to be controlled independently, improving fuel efficiency and providing a quieter operator environment. A new boom float option allows the boom to move freely up and down without hydraulic flow, while a temporary reset button allows the ability to momentarily disengage the float, allowing hydraulic flow to activate the boom.
