Decline.When (12-2) oil cylinder B is in retracted position, (7-1) stroke valve A detects that (12-2) oil cylinder B retracts in place, (7-1) row
P leads to B, A and leads to T opening (10-2) hydraulic control one-way valve B on journey valve A, and (12-1) oil cylinder A control oil circuits are got through, under oil cylinder can rise
Drop.
When (8-2) hand-operated valve C leads in P under A, B lead to T location, (12-1) oil cylinder A is fallen into place after stroke valve detects, row
Journey valve P leads to oil circuit when B, A lead to T location and opens (10-1) hydraulic control one-way valve A, (9-2) logical valve D, and (9-2) logical valve D is oil circuit
Cut off oil cylinder pressurize.When (8-2) hand-operated valve C is in the case where P leads to the logical T location of B, A, (12-1) oil cylinder A falls into place stroke valve and detects
Afterwards, stroke valve P leads to oil circuit opening (10-1) hydraulic control one-way valve A, (9-2) logical valve D oil circuits when B, A lead to T location and does not cut off, still
Persistently give oil cylinder pressure supply.
When (8-1) hand-operated valve C leads in P under A, B lead to T location, (12-2) oil cylinder B is fallen into place after stroke valve detects, row
Journey valve P leads to oil circuit when B, A lead to T location and opens (10-2) hydraulic control one-way valve B, (9-1) logical valve C, and (9-1) logical valve C is oil circuit
Cut off oil cylinder pressurize.When (8-1) hand-operated valve C is in the case where P leads to the logical T location of B, A, (12-2) oil cylinder B falls into place stroke valve and detects
