C20H Carrier Mounted Splitter

The C20H is the largest Darda splitting cylinder and is designed for conjunction with a 5-7 ton excavator. The cylinder is mounted to the carrier using one of four different methods: chain, carriage, and two different types of rigid mounting configurations. The C-20 is extremely well suited for ledge work and larger trenches, and is effective at removing large blocks of rock.
