<p>The invention relates to lifting-lowering devices, particularly it can be applied for lifting -lowering of humans especially those with disabilities and also it can be used for load lifting-lowering. Seeking to reduce consumption of electrical energy to increase lifting safety and lifting capacity in the elevator which consists of vertical frame (1) with guides (2) to which cabin (3) is attached movably, lifting device and control system the lifting device consists of hydro station (12) to which connected is hydraulic cylinder (5) which in turn is by means of pulleys (8) is joined with chains (9), the latters by one ends being attached to the bottom part of the frame (1) and by the other ends to back (wall 10) of cabin (3) the emergency braking mechanism (17) to which is attached also. Besides the hydro station (12) consists of electric motor (13) joined to hydraulic pump (14) the inlet pipe of which is submerged into the tank of hydraulic liquid and the outlet pipe is connected to the valve (15) which in turn is connected with hydraulic cylinder (5). Also the emergency braking mechanism (17) consists of a housing (18) onto the axle of which two pulleys are mounted one of them being eccentric 19 with a fixed rod (20) while the other pulley (21) is with two hooks (22) fixed on the opposite sides of the pulley on axles with the possibility of rotation.</p> |
