CATERPILLAR M318 CRAWLER EXCAVATOR

The Caterpillar M318 is a versatile wheeled excavator engineered for efficient material handling and excavation across diverse jobsites. Powered by a Cat C4.4 engine, this machine delivers 129 kW (174 hp) of power while meeting U.S. EPA Tier 4 Final, EU Stage V, and Korea Tier 4 Final emission standards. The M318 operates at a rated speed of 2,200 rpm and features cold start capability down to -18°C and high-ambient cooling capacity up to 52°C. With an operating weight of approximately 43,980 lbs, the M318 maintains excellent maneuverability on jobsites while delivering substantial digging force. The machine features a maximum travel speed of 21.7 mph, enabling efficient movement between work locations. Its hydraulic system provides a maximum flow of 254 L/min with equipment pressure capacity of 37,000 kPa, supporting powerful and responsive operation. The M318's working envelope includes a maximum reach at ground level of 30'3", a vertical wall digging depth of 15'1", and maximum digging depth capability of approximately 24 feet. Equipped with a 0.91 m³ (1.19 yd³) bucket and 2.5-meter stick, the excavator delivers bucket forces of 119 kN and stick forces of 75 kN under ISO conditions. The swing mechanism operates at 9.4 rpm with maximum swing torque of 44 kN·m, enabling precise positioning and smooth material placement. Standard dimensions include an operating length of 27'9" and width of 8'6", making the M318 suitable for confined spaces while maintaining adequate digging reach. Dual pneumatic tires (10.00-20) provide mobility and stability across varied terrain.
