摘要： PURPOSE:To provide a lifted cargo guide device of a container crane where the movement of a flipper to be separated from the side wall of a spreader is completely prevented by a flipper fixing device, and the positioning relative to the container of the spreader is correctly executed when the flipper of the spreader is externally inserted into the container. CONSTITUTION:In a lifted cargo guide device of the container crane, a plurality of flippers 5 which are vertically provided at the corner part of a spreader 4 so as to change the angle of vertical provision are externally inserted around a container 12 to be lifted, and the position of the spreader 4 is modified so as to accord with the container 12 to lift the container. When the flipper 5 is externally inserted around the container 12, a flipper fixing device 9 to restrict the movement of the flipper 5 to be separated from the side wall of the spreader is provided between the spreader 4 and the flipper 5.

摘要： PURPOSE:To prevent lowering in swinging control precision by a fluctuation of lifting load, in a lifting load bracing control unit for crane, by detecting the load of a suspended article to correct the rope length. CONSTITUTION:The rope length (l) is measured by a rope length sensor 1 and inputted to a processor 4. The load (m) of a suspended article is detected by a load sensor 2 and inputted to a function generator 3. The function generator 3 determines a correction value l to the rope length corresponding to the inputted load (m) and sends it to the processor 4. The processor 4 corrects the rope length according to the inputted correction value l and rope length (l) and also conducts operation of period, further calculates the moving acceleration of a trolley, and controls a crane body 5 so as to suppress the swinging of the suspended article.

摘要： PURPOSE:To prevent running with a meandering motion even when difference is produced in diameter of left and right driving wheels by correcting and controlling independently the value of rotational speed command to left and right driving wheels based on obtained diameter ratio data. CONSTITUTION:An arithmetic control unit 25 estimates and calculates the diameter ratio of left and right driving wheels based on the variation DELTAx, DELTAtheta of amount of positional deviation (x) and its deviation angle theta at every time interval DELTAt, and sets a speed correcting value that makes, for instance, the running speed of the left driving wheel sufficiently higher than the right driving wheel, and supplies to speed command signal correcting signals 21R, 21L. Thereby, locus of traveling of the body 11 of a crane is reversed to right turn movement of radius R2 around a point O2. Then, the amount of positional deviation (x) and deviation angle theta of the body 11 of the crane are converged gradually to zero, and when the locus of traveling coincides with a reference line L, deviation data '0' is detected by a detecting device 22. The arithmetic control unit 25 calculates the value of speed command for each wheel independently that makes substantial traveling speed of each wheel equal based on the diameter ratio of left and right driving wheels calculated at the time of sampling of steering data, and gives to speed command signal correcting sections 21R, 21L.

摘要： PURPOSE:To reduce the maintenance cost by forming a painting apparatus of an elevating cable equipped on a self-traveling carriage, a turntable, a locating table, and a working head. CONSTITUTION:When a traveling apparatus 20 is pulled up above an object 3 to be painted, heads 11 and 19 are elevated to the uppermost position of an elevating stroke by driving a head elevating motor 35 through a screw jack 38 and a screw 36. Then a head moving table 25 is moved onto a guide rail 29 through a ball screw 30 by driving a head locating motor 28. The detection of the position is carried out by a distance sensor 47 provided to a brushing cover 13. When a traveling carriage 39 travels for a speified distance, a head elevating table 34 is lowered by a specified stroke by driving the head elevating motor 35 to run the travelling carriage 39 in the reverse direction. And the brushing is automatically carried out.

摘要： PURPOSE:To increase controlling accuracy later on by a method wherein optimum operation is manually carried out during initial one cycle to permit the loci of a trolley and a bucket to be memorized, and proper operational processing is provided for carrying out teaching. CONSTITUTION:A trolley 22 is moved on rails 21 by the operation of a driving unit 25 for rope-winding and used to effect unloading of a bucket 30 between a hold 32 and a hopper 33. The unit 25 is manually operated during initial one cycle. The travelling distance and speed of the trolley 22 between loci, and the position of the glove bucket 30 as well as its moving speed are measured on the basis of wound and drawn rope, while the data are read in a memory 37. Based on the data, polygonal line characteristics are computed and, in addition, integral value correcting and reduction to close loop processes are added to the computed ones in order to provide teaching. The arithmetic process is carried out in an arithmetic controller 42.
