Front Linkage
Front Linkage
Front linkage variations on the 315C allow for the use of one boom, three sticks and two bucket-types (excavation and heavy-duty rock). Using these combinations improves the general-purpose versatility of the 315C by suiting it to a diverse range of applications.
Boom
The boom on the 315C is designed to provide maximum digging capability. Caterpillar booms are manufactured with high-tensile steel for upper, lower and side plates and are robot welded for consistent quality.
Stick
Three sticks are available on the 315C. 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 high-stress 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.
Bucket Linkage
The bucket linkage on the 315C includes the bucket cylinder, idler link and power links.
Bucket Flop Adjustment Mechanism
All 300 family excavator buckets are equipped with a bucket flop adjustment mechanism which allows the operator or serviceman to reduce the side play at the bucket to stick-nose connection.
Linkage Bearings
New bearing technology has extended the front linkage greasing intervals for all bearings.
Operator Station
