摘要： PROBLEM TO BE SOLVED: To provide a conveyance carrier with favorable workability hardly affected by rigidity of a container. SOLUTION: In this conveyance carrier 100, since a pair of carriers 1A and 1B is connected by a telescopic frame 40 and do not move independently, control is easy and they do not apply excessive compression, tension, bending or the like on the container. The pair of carriers respectively comprises a carrier body 10, an elevating part 20, and a support part 30 elevated by the elevating part. The support part has a chuck to be inserted in a support hole of a part to be supported of the container 200. The chuck inserted into the support hole of the part to be supported of the container is fixed so as not to rotate and the container is raised by the elevating part to move it to a destination by a power means for moving. The power means for moving are respectively provided in each carrier body to allow tight turns and provide favorable workability. Since an upper face of the container is maintained in a free state without anything engaged to it, a set of lifting work by a crane can be performed while supporting the container by the conveyance carrier.

摘要： PROBLEM TO BE SOLVED: To perform the landing of load at an accuracy within the predetermined allowable value range. SOLUTION: A load, which is hoisted by a hoisting wire 6, is lowered for landing. At this stage, hoisting height of the load 5 is measured by an encoder 10, and while displacement of oscillation of the hoisted load 5 is measured by an oscillation sensor 9. Oscillation speed, angular velocity, amplitude, phase angle and the time to be required for landing are obtained on the basis of the measured hoisting height and the displacement of oscillation, and furthermore, estimated displacement of oscillation at the time of advancing the required time phase is obtained, and when this estimated displacement of oscillation is lowered to the predetermined landing allowable value or less, landing is performed.

摘要： PURPOSE: To perform exact travel by detecting the amounts of deviations from a guide line at two fixed points before and behind a traveling object with the passage of time, calculating manipulated variables by calculating a deviation angle, deviation angular velocity and offset correction amount, and controlling the amount of deviation to '0' by applying velocity difference between left and right traveling motors using these manipulated variables. CONSTITUTION: The traveling motors are provided to respectively drive left and right axles, and the traveling object travels along the guide line drawn on the surface of a road. Amounts x1 and x2 of deviations from the guide line at two fixed points before and behind the traveling object are detected every moment. A deviation angle θ to the guide line, deviation angular velocity θ' and offset correction amount are calculated while using the detected values x1 and x2 on condition of x=x1 , x=x2 or x=(x1 +x2 )/2. Based on these results, a manipulated variable Δ' is calculated by an expression and the velocity of the left side or right side traveling motor is respectively controlled by using this manipulated variable Δ'. Thus, the deviation amount is controlled to x1 =x2 =0 by applying the velocity difference between the left and right traveling motors.
