The SGPC2000 Front Shovel Clam Cylinder (also known as the Clam Shell Cylinder) is a specialized hydraulic actuator designed for the bottom-dump bucket of Komatsu PC2000-8 loading shovels. This cylinder is a direct, heavy-duty replacement for OEM Part Number 707-E1-01881.
Positioned directly on the bucket assembly, this cylinder controls the opening and closing of the shovel jaw. Given its exposure to falling debris and high-frequency cycling during loading, SEIGO Machinery has engineered this unit with reinforced protection and rapid-response sealing systems to ensure reliable “bottom dump” performance in mining operations.

Key Features & Operational Reliability
-
High-Cycle Durability: Engineered for the rapid open/close cycles of loading shovels. Our cylinders utilize advanced low-friction seals to reduce heat generation and wear during continuous dumping operations.
-
Clam Shell Optimization: Provides precise control over the clam shell bucket, ensuring tight closure to prevent material spillage during swing and fast opening for efficient truck loading.
-
Impact & Debris Protection: The piston rod is induction hardened to HRC 55-60 to resist impact damage from falling rocks, a common issue for cylinders mounted on the bucket structure.
-
OEM Interchangeability: Fully compatible with the original hydraulic piping and mounting pins for 707-E1-01881, allowing for a quick swap-out to minimize machine downtime.
Applications
-
High-production truck loading
-
Open-pit mining (Coal, Copper, Iron Ore)
-
Overburden removal operations
