摘要： PURPOSE:To detect a damage of a bearing or the like at the early time and improve the operation efficiency by providing a control means for controlling the operation of a failure of stub roller alarm device and the operation of a belt conveyor on the basis of the amplitude by vibration of a stub roller. CONSTITUTION:A distance measuring sensor 26 measures a distance from a stub roller 21, and outputs a result of this measurement to a computing means 27. The computing means 27 computes the amplitude by vibration of the stub roller 21 on the basis of the detecting signal from this distance measuring sensor 26, and output a result of this computing to a control device 28. The control device 28 performs the control on the basis of a largeness of the amplitude by vibration of the stub roller 21 output from this computing means 27, and in the case where this amplitude by vibration of the stub roller is smaller than a preset value, the control device 28 continues the operation of a belt conveyor type continuous unloader, and in the case where this amplitude by vibration is larger than the preset value, the control device 28 operates a failure of stub roller alarm device 30, and furthermore, stops the operation of the belt conveyor.

摘要： PURPOSE:To do work for handling sea cargoes simultaneously on wharf where ships are laid on both sides by pivotally supporting the center of a derricking boom on a swivel provided near a cargo-handling quaywall side on a travel gantry and providing a gilled conveyor thereon. CONSTITUTION:The center supporting points of an unloader swing mechanism 1, an A frame 2 and a derricking boom 3 are provided a distance 10 from the center of a travel gantry 05 to a cargo-handling wharf wall side. Cargoes 09 in a ship 01 are taken up in a vertical unloading area 08, carried to a chute 7 on the other side via a gilled conveyor without being slided and unloaded to a ground conveyor 012 via a relay conveyor 8 and a chute 9. During cargo handling, the end on the balance weight 4 side of the derricking boom 3 is always located inside the opposite-side wharf wall line of a quay 03, and so other in-a-heap ships 02 can freely come alongside and go away from the opposite-side quaywall anytime. As a result, such troubles that other ships 02 are anchored to wait for unloading are dissolved.

摘要： PURPOSE:To reduce wearing, vibration, noise, etc., to improve durability and further to miniaturize an intermediate guide [art of a chain link and the column end part, in a device. CONSTITUTION:Since each guide roller of guide roller train of small diameter, set up along circular arc-shaped moving path (guide roller support) 8 to 11 of fixed radius of curvature, is brought into contact with one side of a bucket chain link, to change a direction of a chain 1 by rolling contact of each guide roller, an impact generated at the time of meshing relating to a sprocket is eliminated, to prevent generating vibration and noise. Since each guide roller in a guide roller train of small diameter is smoothly rotated, also wearing due to slipping between each guide roller and the chain link is eliminated, to resist against use for a long period. The guide supports 8 to 11 are small in size, and when used in an intermediate guide part and column lower part of the bucket chain 1, miniaturization thereof is performed.
