The mechanical guided grab is an excavation tool used for creating deep trenches in foundation projects, specifically for diaphragm walls. It attaches to a carrier machine or crane to excavate narrow, deep slots that are typically stabilized with bentonitic mud before concrete is poured. The system utilizes a guided mechanism to maintain verticality and precision during the digging process.
This unit is the CMS 450, manufactured by CMS. The design incorporates jaws that operate to cut and extract material from the ground, suitable for various soil types ranging from loose sand to hard clay. The grab can be fitted with replaceable teeth to assist with ground penetration.
Mechanical grabs of this type function by using a closing and opening mechanism to manage the excavation cycle. The guided structure ensures the tool remains aligned within the trench, which is necessary for the structural integrity of the foundation being installed. These tools are essential for civil engineering projects involving high-rise buildings, tunnels, and bridges where deep, stable sub-surface support is required.
