Demolition hammer with optimized resistance

摘要

A demolition hammer (1) with optimized resistance, which comprises a body (2) for the containment of valve means for distributing a fluid medium to a linear actuator (3) provided with a piston which can move in a reciprocating manner along a percussion direction and operates on a demolition tool (5) which is guided so as to slide in a reciprocating manner by a support (4), the body (2) and the support (4) being substantially aligned along the percussion direction with the actuator (3) interposed between them. The demolition hammer (1) is further provided with a plurality of tension members (6) for the connection of the body (2) and the support (4), each of which has a first end associated with the body (2) and a second end associated with the support (4) by respective connection assemblies (7; 7'). At least one of the connection assemblies is of the obstacle type (7').
