Guided grab for Casagrande DL6

The guided grab is an excavation tool used in heavy machinery for deep foundation work, diaphragm wall construction, and underground structural projects. It functions by attaching to the boom of the machine, allowing for vertical excavation of narrow and deep trenches. The grab features two articulated jaws that operate via the hydraulic system of the carrier machine to extract material from the ground.

This component is specifically designed for the Casagrande DL6 model. The guided system enables the operator to control the orientation and position of the grab during the digging process, which is necessary for maintaining verticality and precision in trenching operations. The assembly includes provisions for mounting cutting teeth or blades to the jaws to assist in soil penetration.

In foundation machinery, a grab serves as the primary earth-moving attachment for creating vertical shafts or walls. By utilizing hydraulic force to close the jaws, the tool captures soil or debris, which is then lifted to the surface. The guided nature of this specific grab ensures that the excavation path remains consistent with the project requirements, minimizing lateral deviation during the digging cycle.
