摘要： PROBLEM TO BE SOLVED: To provide a labor-saving grabbing workboat which can arbitrarily change the entire weight of a dead-weight while using use an existing dead-weight main body even if a bucket weight is largely changed due to exchange etc. of a grab bucket, to thereby continuously exert bucket driving power saving effect.
SOLUTION: The labor-saving grabbing workboat is formed of: an elevation guide frame 4 which is erected on one side of a work bench 2, and has a standing block 5 axially supported on an upper portion thereof; the dead-weight W which is vertically movably guided by the elevation guide frame 4, and has a fall block 6 axially supported thereon; a rope A which has one end thereof fastened to the grab bucket G and the other end thereof wound via a sieve S and the standing block 5 on the fall block 6, for hanging the dead-weight W therefrom; and an elevating/lowering means CY which is interposed between the dead-weight W and the work bench 2 or the elevation guide frame 4, and vertically extended, for elevating/lowering the dead-weight W. In the labor-saving grabbing workboat, the entire weight of the dead-weight W is totally or partly offset by the weight of the grab bucket G. Herein a pontoon 1 of the grabbing workboat is composed of a weight changing means C for changing the entire weight of the dead-weight W to an arbitrary value.

摘要： PROBLEM TO BE SOLVED: To reduce the weight and size of a grab bucket type soil lifting device and to reduce the cost by reducing the number of parts and simplifying the structure, of which the grab bucket type soil lifting device has a press-in plate in the bucket for pushing in the soil, and the soil caught by the bucket can be forcibly fed into a conveyance pipe under pressure through a check valve. SOLUTION: The soil lifting device G comprises a soil push-out port 20 provided in a shell S of a pair of shells S, S' in a manner that it is opened on a side of a soil housing chamber C formed between the pair of shells S, S' upon closing of the shells S, S', a conveyance pipe P which is connected to the soil push-out port 20 at its end and has flexibility at least partly, a main check valve Vm blocking back-flow of the soil from the conveyance pipe P to the soil housing chamber C, a single push-in plate PS formed to extend to the full width of the soil housing chamber C and is pivotally supported by the other shell S' so that it may rotate in a reciprocating manner between one side and the other side of the soil housing chamber C when the shells S, S' are closed, and a push-in plate drive device Ap rotatingly driving the push-in plate PS.
