The Delta-box frame in combination with a single large diameter cylinder – for powerful closing – ensures low reactive forces at the hinging points. The application of a single, hydraulically cushioned cylinder makes the grab easy to service and reliable because of the simplicity of the hydraulic system. The shells are equipped with a perforated shell plate made of high-grade material as standard. This construction gives extra torsion rigidity to the shells, prevents material getting stuck in the shells and gives optimal visibility on the job.
Side plates and reversible, divided bottom blades are manufactured of extra thick, durable material. The divided bottom blades can also be interchanged up to 3 times (starting from D19H-P-HD) so that wear at the corners can be dealt with and wearing-material is not wasted unnecessarily.
