Abstract

Гидропривод грузоподъемной лебедки, содержащий гидрораспределители, параллельно подключенные гидромоторы, два насоса, выход одного из которых соединен с линиями подъема и опускания груза посредством гидрораспределителей, отличающийся тем, что насос включается гидромуфтой, а второй насос предназначен для заполнения гидромуфты рабочей жидкостью.A hydraulic hoist of a hoisting winch, containing hydraulic control valves, hydraulic motors connected in parallel, two pumps, the output of one of which is connected to the lines of raising and lowering the load by means of hydraulic control valves, characterized in that the pump is turned on by a hydraulic coupling, and the second pump is designed to fill the hydraulic coupling with a working fluid.
