Recovery System (Pulled Hook) For Loaders

-Allows to remotely release the brakes in case of need to retrieve a buried unit or to remove it quickly from the section in case of breakdown.


In some breakdown cases like engine failure or transmission breakdown, or even roof collapse (if machine operated under unsupported roof with RRC), the loader can be stuck and block the production site, generating important productivity loss.

Removing the unit from the location without all functional components, or without easy and safe access to the operator compartment, can be hazardous.

In order to mitigate this risk and makes easier to remove the loader from the location, Sandvik has developed a Recovery System that allows to release the brakes when pulling on the towing hook.

On the LH514 and LH517, the system is electro-hydraulic. When the recovery hook is pulled, a pressure accumulator provides pressure to release the brakes. More pressure, if needed, is produced by an electric pump.
On LH517i and LH621i, the system is fully hydraulic. The retrieval hook is connected to a cylinder which extends when the hook is pulled. Oil from the cylinder flows to the brake pistons releasing the brakes.
