The P-Series hydraulic system is fully enclosed and protected, reducing the risk of damage to hoses and other components.
Kinshofer, a global manufacturer of excavator and loader crane attachments, offers an extensive range of excavator orange peel grapples for scrap, demolition, loading and unloading applications. Unlike other grapples, the P-Series hydraulic system is fully enclosed and protected, reducing the risk of damage to hoses and other components. Additionally, the grapple's unique tine design enhances material penetration, increasing the amount contractors can safely secure in one cycle and saving time on the job site, according to the manufacturer.
“We've spent 42 years researching and testing, in collaboration with our subsidiaries and clients, to develop the best orange peel grabs on the market,” said Francois Martin, Kinshofer North America general manager. “During this time, we've spent countless hours ensuring components are FEA optimized to improve the attachment's life span while providing top of the line speed and force.”
The P-Series orange peel grapples handle loads up to 4 cu. yd. within one cycle and are available with three, four or five tines. The grabs also come in four different tine profiles including fully closing, half closing, pointed and wide style pointed, effectively providing an optimized solution for any material. The slim design of the tines guarantees maximum penetration of scrap and demolition piles.
The attachment's hydraulic system is completely protected through its yoke system design. This prevents material from falling into the system and ripping or damaging components or hoses, a common problem in demolition and recycling applications. Kinshofer's hydraulic cylinders are fitted with replaceable piston rod protection that is hydraulically cushioned for added durability. Removable covers provide quick access to the hoses, oil distribution system and grease points for easy serviceability.
The system is fully integrated with a heavy-duty slewing ring, which allows for 360-degree continuous rotation and ensures optimum force during operation. Kinshofer also designed the robust slewing ring to withstand the stress and excessive loads of different operating styles, significantly extending the grapple's service life. The non-return valve, located directly under the rotation device, retains the grapple's load to increase safety during unintended pressure drops.
Kinshofer Orange Peel grapples are FEA optimized — meaning a 10 percent weight reduction at 20 percent stress reduction — and their overall structural parameters are maximized to meet the toughest requirements and increase longevity. To further improve durability, Kinshofer manufactures its tines and wear plates with wear-resistant 400 HB steel and its weld-on tips with high-resistant 500 HB steel.
The tine heads and main bearing are widely spaced to reduce the face pressure in the bushings, as well as absorb distortion if the grab is overloaded. The induction-hardened pins are seated in steel bushings and the lateral thrust discs provide a solid support for the tines and also reduce wear during operation.
The P-Series standard package includes the grab, rotator or integrated slewing ring rotation, head plate and non-return valve. A hose guard is available as well as a bolt-on bottom plate with a welded lifting eye to hang a magnet. A heavy-duty, rigid-mount model with three tines and a larger surface bearing is also available to handle bulky scrap material. The attachments are available for excavators with a carrier weight ranging from 16 to 88 tons.
Kinshofer offers a two-year warranty on its P-Series orange peel grabs.
