Hydraulic apparatus for excavators and construction equipment in general

A hydraulic rotating crusher apparatus for construction equipment, comprising a support structure connectable to a movable arm of the construction equipment, a pair or rotating drums including a plurality of teeth, a pair of hydraulic motors, each arranged for movement of a respective drum, and a rotating flow divider device, said rotating flow divider device including a pair of further hydraulic motors, said further hydraulic motors each including a coaxial shaft, the flow divider device further including a connection element interlinking the coaxial shaft of one further hydraulic motor with the coaxial shaft of the other further hydraulic motor so that the interlinked shafts are rotationally engaged, said hydraulic rotating crusher apparatus further comprising a common inlet for receiving a supply of operative fluid provided by the construction equipment, the common inlet being divided in two inlet connections, each inlet connection providing a supply of operative fluid to a respective one of the further hydraulic motors and a pair of outlets, each outlet connected to a respective one of the further hydraulic motors, which provide said supply of operative fluid, suitably divided by said further hydraulic motors, to said pair of hydraulic motors, said rotating flow divider device further including a flywheel connected to said connection element such that, when the one of the rotating drums starts to slow down as a result of friction of processed material, an initial effect of the flywheel prevents the further hydraulic motors from slowing down.
