MECALAC 11MWR CRAWLER EXCAVATOR

Technical Description

The Mecalac 11MWR is a compact, high-performance wheeled excavator designed for versatility, mobility, and stability in urban and road construction environments. Equipped with a 3.6-liter Deutz TCD L4 water-cooled engine delivering 75 hp (56 kW) at 2200 rpm and 287.7 lb-ft torque at 1300 rpm, it offers robust power for demanding operations. The machine features a unique Mecalac boom with 5 degrees of freedom and a strong dipper stick cylinder capable of a maximum breakout force of 13,488.6 lbs, delivering exceptional lifting and digging power. With a maximum digging depth of 12.5 feet and a reach along the ground up to 24.7 feet, the 11MWR provides operational flexibility while maintaining compact dimensions—shipping height and length of 9.7 and 15.9 feet respectively, with an overall width of 98.5 inches. Its ground clearance is 1.6 feet, and it boasts a tail swing radius of 4.8 feet, enhancing maneuverability in confined spaces. The excavator operates at an optimal weight of approximately 24,229 lbs, balancing stability and transportability. Hydraulic performance is driven by a variable displacement pump with a flow capacity of 43.6 gpm and a system relief pressure of 4350 psi, supported by a 20.4-gallon hydraulic fluid reservoir. The fuel system holds 43.6 gallons for extended operation. The electrical system is powered by a 12 V, 100 Ah battery with a 14 V (120 A) alternator ensuring reliable starts and operation. The 11MWR combines wheeled and crawler advantages through a low center of gravity and four-wheel steering, enhancing off-road capability, stability, and lifting capacity, making it ideal for multi-purpose tasks including shoveling, lifting, and urban infrastructure projects.
