Zusammenfassung:FIELD: stroke restricting mechanism preferably employed in apparatuses with high inertial characteristics of working tools, such as load-lifting devices driven by hydraulic engine. ^ SUBSTANCE: stroke restricting mechanism has pusher connected with working tool, double-armed lever and device provided with input link and adapted for controlling of working tool drive. Pusher is equipped with shock-absorber mounted at its end. Double-armed lever has long and short arms and is positioned for cooperation with its long arm through shock-absorber with pusher and with its short arm with input link of working tool drive controlling device to provide for temporary blocking of input link. ^ EFFECT: increased efficiency in restricting stroke of working tool having high inertial characteristics. ^ 1 dwg
