Petersen Industries, Inc. Awarded Patent on Innovative Crab Attachment

Petersen Industries, Inc., manufacturer of grapple trucks and bulky waste collection systems, announces the issuance of U.S. Patent #8,079,799 B2 for the apparatus and method for lifting containers, an attachment known to Petersen as the “Crab”.

This patented device is a lifting apparatus, consisting of an elongated support bar with hook assemblies mounted on each end. The operator controls open and close functions of the hooks from a control platform behind the cab. A hydraulic cylinder and piston drives the hooks into various positions to securely connect into the pockets of an ANSI Z245.60 compliant container and maneuver it as needed. Petersen’s CP-3 container delivery system comes standard with this patented device, but the Crab can also be purchased as an interchangeable attachment on other Lightning Loader® models.
