312C L Hydraulic Excavators

Improved performance and rugged durability combine to maximize productivity. The 312C is powered by the Cat 3064 T engine. This engine includes several design features which enhance performance, efficiency and reliability.

Engine

The four cylinder turbo-charged Cat 3064 T engine is built for power, reliability, economy and low emissions.

Hydraulics

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

Undercarriage and Structures

Durable undercarriage absorbs stresses and provides excellent stability

• Front Linkage. Front linkage variations on the 312C allow for the use of one boom, two sticks and five buckets. Using these combinations improves the general-purpose versatility of the 312C by suiting it to a diverse range of applications.
• Boom. The boom on the 312C is designed to provide maximum digging capability. Caterpillar booms are manufactured with high-tensile steel for upper, lower and side plates and robot welded for consistent quality.
• Stick. Two sticks are available on the 312C. The customer's working envelope and bucket capacity needs determine their stick choice.
• Boom and Stick Construction. Built for performance and long service life, Caterpillar booms and sticks are large, welded, box-section structures with thick, multi-plate fabrications in highstress areas.
• Buckets. High tensile strength steel is used in high-stress areas for excellent wear and shock resistance. The side plates are tapered to prevent contact of the bucket sidewalls during trenching operations. All buckets are general purpose, share a common side profile and have lifting eyes.
