摘要： PROBLEM TO BE SOLVED: To provide a grab bucket which can surely prevent mud from leaking from a drip hole, by firmly closing the drip hole with an opening/closing body and can quickly discharge the internal pressure of a shell when the internal pressure increases.
SOLUTION: A triangular drip hole 15 is opened in the upper wall 5a of the bucket shell 5. The opening/closing body 17 which opens and closes the drip hole 15 from the outer surface side is fixed along one side of the drip hole 15 and supported so as to be swingably opened and closed around the fixed end side. The opening/closing body 17 comprises a rubber lid 18 which is stuck to the opened peripheral edge wall of the drip hole 15 in a closed state, and a regulating body 23 which inhibits the rubber lid 18 from falling into the drip hole 15.

摘要： PROBLEM TO BE SOLVED: To provide a grab bucket for a revetment block capable of preventing the whole bucket from being inclined when the bucket is lifted or lowered or when a grab is opened or closed and efficiently installing or removing the revetment block. SOLUTION: This grab bucket is provided with a hanging rope 5 supporting an upper frame 1 and an opening/closing rope 6 supporting a lower frame 2. The opening/closing rope 6 comprises a pair of right and left front-stage ropes 24 and 24 symmetrically arranged across the hanging rope 5 and a next-stage rope 25 supported by the front-stage ropes 24 and 24 at both ends. The next- stage rope 25 is endlessly wound on an upper pulley group 30 and a lower pulley group 31 provided between both frames 1 and 2. Since the rope reaction of the opening/closing rope 6 applied to the grab bucket is made uniform on the right and left, the grab bucket can be prevented from being inclined by the rope reaction.

摘要： PROBLEM TO BE SOLVED: To prevent a bucket from swinging in the longitudinal direction at the start of closing the bucket by constituting so that force generated in an opening/closing rope of a part wound round an upper vibration control sheave and force generated in an opening/closing rope of a part wound round a lower vibration control sheave are offset by each other. SOLUTION: A dredging grab bucket is installed on a lower frame 2 by journalling a pair of shell parts 1A and 1B by a shaft 3 so as to be freely openable and closable. The lower ends of connecting levers 4A and 4B are connected to the respective shell parts 1A and 1B by a pin, and the upper ends of the respective connecting levers 4A and 4B are connected to an upper frame 5. Two upper sheaves 11 composed of a vibration control sheave and an energizing sheave are similarly journalled to this upper frame 5, and two lower sheaves 12 composed of a vibration control sheave and an energizing sheave are similarly journalled to the lower frame 2. An opening/closing rope 8 to open and close the bucket is wound in order between the upper and lower sheves 11 and 12, and the tail end of the opening/closing rope 8 is locked on the upper frame 5 by a fixing metal fitting 9.
