摘要： A crane spreader for use in lifting a container includes an attachment unit, a head block, a frame unit, a position adjustment unit and a fixation unit. The attachment unit detachably attaches the crane spreader to an upper surface of the container. The head block has a pulley connected to a trolley of a crane through a cable and coupled to the attachment unit to restrict a horizontal movement the attachment unit with respect to the head block. The frame unit is supported by the head block to be horizontally movable with respect to the head block, the frame unit being disposed below the head block with a gap therebetween. The position adjustment unit aligns the frame unit with the container by displacing the frame unit with respect to the attachment unit. The fixation unit engages the container with the frame unit.

摘要： Most vibration generators that use rotating eccentric masses of prior arts have disadvantages in controlling vibration magnitude such as stopping equipment, adjusting intermittently, or limitation on control range. In the present invention to continuously change the direction of a generated vibration force or its magnitude, the principle of synthesizing simple harmonic motions by phase shifting is used and two methods, called a mechanical phase shifting and a motor speed controlled phase shifting, are provided. A mechanical phase shifting device includes an angle adjusting plate to change the phases of two eccentric mass rotators and two pairs of gears and links for a reverse rotation of eccentric masses. A motor speed controlled phase shifting is enabled by acceleration and deceleration of a motor. A moment generator comprises two sets of eccentric mass vibrators connected by extending shafts between them and can be used for industry shakers, stabilizer's for floating bodies, and so on.
