Primary Lifting Force: Generates the immense force required to lift the boom, the stick, the bucket, and any material in the bucket. This determines the machine's lifting capacity, especially at range.
Precision Control: Allows the operator to precisely raise and lower the boom with smooth, proportional control. This is essential for delicate tasks like grading, trenching, and placing material accurately.
This 158-8991 boom cylinder is used for 315D 318D excavator.
