Title: Load-support stopper
Inventor: STRILETS VOLODYMYR MYKOLAIOVYCH
Filed: 2001-03-27
Abstract: A load-support stopper relates to machine-building, to stoppers closed by weight of the load being lifted in lift mechanisms of load-lifting machines. New in this invention is the fact that the stopper unit is made as pinion hydro-pump, on its drive shaft there is installed a pinion coming into coupling with toothed wheel rigidly fixed on the shaft being stopped and hydro-system with two closed circuits: the first closed circuit of hydro-system comprises of the pinion hydro-pump named, pipelines and back valve; the second closed circuit of hydro-system comprises of the same pinion hydro-pump, pipelines and controlled throttle; hydro-system has compensation tank with liquid and two additional back valves, compensation tank is connected to the first and the second closed circuits of hydro-system through back valves. Such stopper unit of load-support stopper decreases energy losses to lower the load, with increase of durability due to absence of friction couples, with increase of control of the load lowering due to throttle implementation.
