Document Type and Number:
Japanese Patent JP4789121
Kind Code:
B2
Abstract:
A heavy-duty demolition apparatus for attachment to the boom structure of an excavator, the apparatus having interchangeable jaw sets. The apparatus includes a unitary jaw assembly, having a pair of pivoting jaws connected by a main pivot pin; a first adaptor on the boom structure; a second adaptor on the jaw assembly, the second adaptor engaging the first adaptor, so that the jaw assembly can be easily removed as a unit from the boom structure and another jaw assembly installed on the boom structure; and a lock pin fixed to the first adapter and engaging the second adapter to maintain the jaw assembly in locked relationship to the boom structure. Because of the structure of the apparatus, the distance between the attachment point of the hydraulic ram on the boom structure and the main pivot point of the jaw assembly can be varied between interchangeable jaw assemblies.
