HYDRAULIC RESCUE DEVICE FOR MANUAL MAINTENANCE BY A RESCUE WORKER Russian patent published in 2021 - IPC A62B3/00 B66F3/24 B66F3/25 A62B99/00 F15B15/14 F15B15/28 

FIELD: rescue operations.

SUBSTANCE: invention concerns hydraulic rescue device (1) for manual maintenance by a rescue worker. Rescue device (1) includes hydraulic cylinder (5) having cylinder pipe (6) and at least one piston rod (7, 7') that can be rearranged relatively to cylinder pipe (6), at least one first support surface (17) made on cylinder pipe (6) for the transmitting load of the support of rescue device (1) on the first surfaces of the object, at least one second support surface (19) made on specified at least one piston rod (7, 7') for the transmitting load of the support of rescue device (1) on the second surfaces of the object, and at least one manually operated control valve (14). On side surface (22, 22') of specified at least one piston rod (7, 7'), several marks (23, 23') read by the rescue worker are made, while at least one mark (23, 23') is provided at least for the indication of remaining available residual stroke (24) and/or passed stroke (25) of the rearrangement of specified at least one piston rod (7, 7') relatively to cylinder pipe (6).

EFFECT: invention allows for the control of the residual stroke of the rod of the rescue device, which provides for an increase in the efficiency and the speed of the rescue process.
