Technical Description
The Caterpillar M313D is a high-performance wheeled excavator powered by a Cat C4.4 ACERT engine delivering a net power of 95 kW (127 hp) and maximum torque of 406 lbs-ft at 1,400 rpm. This 4-cylinder, 4.4 L displacement engine meets stringent emission standards while optimizing fuel efficiency and reducing noise. The machine’s hydraulic system features a load-sensing design with separate dedicated swing and implement pumps, delivering up to 50 gpm flow and maximum pressures of 5,076 psi, enabling fast cycle times, high bucket and stick forces, and enhanced lifting performance in heavy lift mode. Various boom and stick configurations offer flexibility, with options providing maximum digging depths ranging from 16.4 to 18.9 ft and maximum reach along ground from 27.1 to 29.7 ft. Maximum cutting heights vary from 28.3 to 33.1 ft, and loading heights up to 24 ft accommodate diverse applications. The M313D’s bucket capacities range from 0.5 to 1.2 cubic yards, with a reference capacity of 0.7 cubic yards. The excavator travels at speeds up to 23 mph (37 km/h) through a gear transmission with two forward and two reverse gears, coupled with a drawbar pull of 17,085 lbs and a maximum gradeability of 58%. Its undercarriage includes heavy-duty axles, wide oscillating and steering angles (up to 35 degrees), and dual 10.00-20 16PR tires, providing mobility and stability. The machine measures approximately 27.3 ft in length, 10.3 ft in height, and 8.4 ft in width, with a shipping height of 10.3 ft. Operating weight varies by configuration, typically around 34,833 lbs. Additional features include a spacious operator cab with advanced controls, rearview camera, and integrated tool control system for programmable hydraulic tool settings, ensuring versatility, comfort, and productivity on-site.
