The document outlines the specifications for the C12H Clamshell Bucket series, designed for excavators with an operating weight between 9t and 12t. The buckets vary in width from 400 mm to 1000 mm, with a consistent opening of 1485 mm and height of 1250 mm. The volume capacity ranges from 170 to 450 liters, and the load capacity is uniformly 3000 kg. The package includes the clamshell bucket, bolt-on teeth, KINSHOFER rotator, non-return valve, and hose guard.
The KINSHOFER Rotator features continuous rotation with two oil passages and overload protection via pressure relief valves. The KM 07 F180-40 model has an upper connection of 84 x 40 mm, a torque of 2000 Nm, and a moment of deflection of 15000 Nm.
Available accessories include upper suspensions with or without pendulum dampers, cardanic adapters for Lehnhoff grab exchange systems, and scrapers for 9t-12t excavators. Adapters for other quick exchange systems are also available.
The operating pressure for opening/closing and rotation is a maximum of 32 MPa, with pump capacities ranging from 40-120 l/min for opening/closing and 20-50 l/min for rotation.
The clamshell bucket is constructed with 500 HB steel for durability, features a generously dimensioned bearing system to reduce wear, and offers excellent digging characteristics due to high closing forces of 37 kN at 32 MPa operating pressure.
