The 311C U is powered by the Cat 3064 T engine. This engine includes several design features which enhance performance, efficiency and reliability.

The engine is designed for high torque rise at middle rpm, a feature that is especially beneficial for heavy-duty use.

Caterpillar hydraulics deliver power and control to keep material moving at high volume

The 311C U hydraulic system was designed to provide a high level of efficiency. With all major components located close together, shorter tubes and lines are needed, resulting in less friction loss in the lines and reduced pressure drops.

Hydraulic Cross Sensing System - improves productivity with faster implement speeds and quicker, stronger pivot turns.

Automatic Boom and Swing Priority - for simpler operation, work mode and power mode switches have been eliminated. Instead, the automatic boom and swing priority function selects the best mode, based on joystick movement.

Controllability - the hydraulic system offers precise control, reducing operator fatigue, improving operator effectiveness and efficiency, which ultimately translates into enhanced performance.

Undercarriage and Structures - DURABLE undercarriage absorbs stresses and provides excellent STABILITY.

Main Frame - rugged, designed for maximum durability and efficient use of materials.

Idler Guard - An idler guard, which is integral to the track roller frame is standard. This guard helps maintain track alignment while traveling or working on slopes.

Blades - for further versatility and to meet more general purposes needs, three blade width options are available on the 311C U.

Shorter Tail Swing Radius - with its reduced tail swing radius, is easier to operate while against walls and in tight areas, reducing the concern of the rear of the machine during operation. The shorter tail measurement allows flexibility for ideal use in urban construction, logging roads, and other space restricted sites.

FRONT LINKAGE - designed in flexibility to help bring higher production and efficiency to all all jobs

Operation Station is designed for simple operation, the 311C U operator station allows the operator to focus on production. It is quiet with ergonomic control placement and convenient adjustments, low lever and pedal effort, ergonomic seat design and highly efficient ventilation. The 311C U’ newly designed and conveniently located monitor allows the operator to monitor machine performance while sitting in a comfortable position.
