Patent

CA 2266220

A construction vehicle attachment in the form of a pulverizer-ripper unit that includes a pair of jaws confronting and closing on one another and an independent ripper-shank that has a replaceable ripper-tooth. Each jaw includes teeth that serve to engage and fracture concrete slabs. The pulverizer-ripper unit operates under power of any one or a combination of hydraulic, pneumatic, electric, or mechanical powers. The teeth on each jaw are alternated at differing lengths and sizes. The ripper-shank is an elongated finger-like projection pivotably mounted on one of the jaws. The ripper-shank is significantly longer than either jaw and has a range of arcuate motion from a parked-position to a fully-deployed-position with at least two intermediate positions therebetween. The ripper-shank can be locked into such an intermediate position and allows an operator to initially rip up or pry up surfaces, sort and properly orient large chunks, and then subsequently pulverize the chunks with the jaws.
