Counterweight Device for Arranging Accumulators Inside the Counterweight of a Working Machine

摘要

Counterweight device in which an accumulator is disposed inside a counterweight, the work machine connecting the accumulator to piping at the machine body side and capable of moving a machine body or work device even though the counterweight is not attached to the body. A counterweight is fixed to a mount base at the rear end part of a swinging frame, an accumulator installed inside the counterweight by means of a temporary placing support structure. The temporary placing support structure can be temporarily placed on and attached to the end plate at the swinging frame side before attaching the counterweight.
