METHOD FOR STARTING ATTACHABLE HYDRAULIC MACHINE FOR DESTRUCTION, CRUSHING OR RECYCLING, AND ATTACHABLE HYDRAULIC MACHINE FOR DESTRUCTION, CRUSHING OR RECYCLING

摘要

PPROBLEM TO BE SOLVED: To provide an attachable hydraulic machine in which huge cutting force can be attained from the remarkably early time point after starting closing movement of at least one hingedly attached jaw and cycle time while the at least one hingedly attached jaw performs opening/closing movement to an opening position and a cutting position and/or a closed position can be further shorten. PSOLUTION: The attachable hydraulic machine is provided with an upper jaw 18 and a lower jaw 16, wherein at least one of jaws is fitted by a hinge to a bearing shaft 19 which is arranged on a housing 12 so that at least one of them moves rotatively. The jaws that are fitted by the hinge are started by a first hydraulic cylinder 26 and at least one other cylinder 41 acting on them, thereby moving from the opening position 21 to the cutting position and/or closing position and further moving oppositely. The hydraulic cylinders acting on the jaws that are fitted by the hinge are pressurized simultaneously. Alternatively, only one hydraulic cylinder is pressurized at first when at least one jaw that is fitted by the hinge starts the closing motion from the opening position and then at least one other hydraulic cylinder is similarly pressurized when the compression force to be required during the closing motion becomes large.
