The DMS Digging Grab with upright cylinder is the first choice for civil engineering underground work and operation in confined spaces such as the excavation of shafts. With its remarkable design, all the advantages of our patented double-acting cylinder technology have been optimally adapted into the vertical position. Due to the almost circular gripper geometry, the external dimensions of opened and closed shells are identical.
Efficient excavation
With increased closing force, the innovative design allows deeper penetration into the ground and the utilization of the full shell volume without material compression.
Optimal gripper geometry
Constant filling capacity during opening and closing increases material movement efficiency, while pivot points in the center ensure a direct force transmission.
The specially developed DMS cylinder drive is the hydraulic heart of our grabs. Due to the double-acting plunger cylinder with oil pressure supply on both sides, the force generated for opening and closing is identical. Inside the cylinder, not only the piston rod is completely encapsulated and protected. The oil channels also run internally, eliminating the need for vulnerable hoses on the exterior.
The vertical position in combination with the centrally located shell pivots ensures ideal force transmission. With this design and technology, DMS creates ideal conditions for performance, robustness and durability.
