Check valve 17-2 repairings, the epicoele fluid of support tank hydraulic cylinder 7 returns to fuel tank by flow divider-combiner 14.
When hoisting container 10 stops running up, spring claw 8-2 is constantly in stretching state, due to solenoid directional control valve
15-1, solenoid directional control valve 15-2 no powers are all in right position, and overflow valve 16-1, overflow valve 16-2 can not reverse flows, therefore support
Tank hydraulic cylinder 7 will not be run downwards in hoisting container pulleying, the latch bracket of latch bracket jaw arrangement 8 moved with support tank hydraulic cylinder 7
Pawl 8-2 provides good support platform for the falling of hoisting container 10；Because the spring claw 8-2 of latch bracket jaw arrangement 8 is with support tank
