This heavy-duty demolition apparatus (10) includes a unitary jaw assembly, having a pair of pivoting jaws (12, 14) connected by a main pivot pin (16); a first adaptor (50) on the boom structure; a second adaptor (60) 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 a lock pin (70) fixed to the first adapter (50) and engaging the second adapter (60) to maintain the jaw assembly in locked relationship to the boom structure. Because of the structure of the apparatus (10), 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.
