PROBLEM TO BE SOLVED: To provide a crusher largely shortening the time the operator remains in contact with PCB by efficiently and rapidly conducting the crushing works of a vessel for extracting PCB oil from oil-filled electrical equipment such as a capacitor and largely simplifying its structure. SOLUTION: The crusher has a base 1, a pair of left-right cutting edges 2 fitted on the base 1 in a space variable manner respectively and a hydraulic cylinder 3 installed on the base 1 in the direction orthogonal to the space variable direction of the pair of left-right cutting edges 2 and used for moving the capacitor B towards the pair of left-right cutting edges 2. An oil receiver 4 for receiving and recovering PCB oil flowing out when the capacitor B is crushed by the pair of left-right cutting edges 2 is fitted under the base 1. COPYRIGHT: (C)2008,JPO&INPIT
