HYDRAULIC EQUIPMENT FOR CONSTRUCTION MACHINE

摘要

To provide a hydraulic equipment capable of supplying hydraulic oil to a hoisting motor via a traveling motor, in which when the hoisting motor and the traveling motor are operated simultaneously, it is prevented that both pressures in the inlet and outlet sides of the hydraulic oil of the traveling motor become high level.SOLUTION: It is provided a switching valve 35 connected to two oil passages 11a, 11b allowing hydraulic oil to flow between a directional switching valve 5 for a traveling motor 2 and the traveling motor 2, which may shift to a first state where the oil passages 11a, 11b are communicated with each other or a second state where the communication is shut off. The switching valve 35 is configured so as to switch from the second state to the first state when the pressure of the hydraulic oil supplied from a directional switching valve 6 for a hoisting motor 3 to the hoisting motor 3 becomes higher than a predetermined value.SELECTED DRAWING: Figure 2
