CAT 311C Hydraulic Excavator

The Cat 311C is an 11.9-ton class utility hydraulic excavator designed for tight and medium-sized job sites where you still need the reach and power of a full-size machine. Powered by a fuel-efficient Cat 3064T turbocharged diesel engine, the 311C delivers smooth, controllable hydraulics and strong digging performance for trenching, pipework, landscaping, small civil projects and general construction. A compact tail swing and well-balanced undercarriage make it easy to work close to obstacles while maintaining excellent stability.

Inside the cab, the 311C offers a quiet, climate-controlled operator environment with good all-round visibility to the work area. The open-center, two-pump hydraulic system with cross-sensing improves implement speed and responsiveness, helping operators work faster and more precisely with less fatigue. With a maximum digging depth of up to 5.59 m and a reach at ground level of about 8.10 m (with the long 2.8 m stick), the machine comfortably handles everyday excavation and loading tasks on site.
