Heavy Duty Selector Grabs for Excavator
The KINSHOFER heavy duty selector grabs are a proven concept that can be applied widely for demolition, recycling and other applications. The grabs are characterized by their extremely powerful closing strength and the robust construction of the yoke thanks to a Delta-box frame with wide pivotal points using bearings and over-dimensioned pins and bearings.
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.
Starting from D32H-P-HD, the heavy duty selector grabs are equipped with twin rotation motors, the smaller versions can be upgraded optionally. Standard is an integrated rotation with sturdy slewing ring.
The application of the standard load safety valve in the grabs open/close circuit ensures safety during operation. Overheating of the oil is avoided and the machine keeps up its cycle speed.
