11.3 for the very big object of weight (6) is rolled, be arranged on from hydraulic oil container (S1) lead to the cylinder chamber that is positioned at hydraulic cylinder (8) piston top that root pipeline (L4) reversal valve (S7) and be arranged on from hydraulic oil container (S1) lead to two pipelines (L2) in hydraulic cylinder (8) cylinder chamber and (L4) between the reversal valve (S10) of connecting pipe (L6) excite, and the 3rd reversal valve (S4) is in no liquid-flow state, and pressure switch (S9) is opened when closing power machine (S2)
11.4 for the very big object of weight (6) being rolled and locking simultaneously, be arranged on from hydraulic oil container (S1) lead to the cylinder chamber that is positioned at hydraulic cylinder (8) piston top that root pipeline (L4) reversal valve (S7) and be arranged on from hydraulic oil container (S1) lead to two pipelines (L2) in hydraulic cylinder (8) cylinder chamber and (L4) between the reversal valve (S10) of connecting pipe (L6) switch to no liquid-flow state by pressure switch (S9).
12. by the method for claim 10 or 11, it is characterized in that: control device is designed to like this, makes it when a hydraulic cylinder (8L) reaches the maximum pressure of predesignating another hydraulic cylinder (8R) be switched to no load state, and is by this way:
By being arranged on the overflow valve in that root pipeline (L5) that leads to hydraulic cylinder (8L) piston top and being arranged on that overflow valve (S14) in the hydraulic oil reflux line and combination valve that constant restriction choke (S17) is formed plays overflow valve, and the cylinder body of a hydraulic cylinder (8L) drives into
Another overflow valve (S15) that almost is arranged on simultaneously in the hydraulic oil reflux line is opened, and the openable flap valve (S16) that is connected overflow valve (S15) back is also opened,
Also make thus corresponding to overflow valve aforementioned overflow valve (S13), that be attached to another hydraulic cylinder (8R) (S13R) and open, thereby make another hydraulic cylinder (8R) not have the total travel of passing by under the situation of tangible back pressure.
