摘要： An apparatus for controlling the running track of a trackless moving body comprising a guide wire, a position deviation sensor unit mounted on the trackless moving body for sensing a deviation of the position of the moving body relative to the guide wire, a steering control circuit connected to the position deviation sensor unit, and a steering drive unit connected to the steering control circuit for steering the moving body. The steering control circuit comprises a first-order lag circuit receiving the output signal from the position deviation sensor unit, a subtractor receiving the output signal from the position deviation sensor unit and the output signal from the first-order lag circuit, and a comparator receiving the output signal from the subtractor. In the steering control circuit, the output signal from the first-order lag circuit is subtracted in the subtractor from the output signal from the position deviation sensor unit so as to detect the rate of variation of position deviation during a predetermined period of time, and the subtractor output signal including the information of the rate of crane position deviation is compared in the comparator with a reference setting, so that the steering drive unit is actuated depending on the result of comparison for causing approaching movement of the moving body toward the guide wire.

摘要： A container crane system comprises a storage area on a crane for storing containers temporarily, a main spreader adapted for conveyance of the containers between the storage area and a ship so constructed that the containers are guided by a cell guide and stowed into a hatch of the ship, and an auxiliary spreader adapted for conveyance of the containers between the storage area and a transport system prepared on the land to the rear of the crane. The main spreader is operated automatically according to operation schedules which are previously stored in a memory by a teaching operation and whose variable components are corrected during the automatic operation through a corrective (or modified) playback operation, while the auxiliary spreader is automatically operated through a programmed operation schedule.

摘要： An apparatus with sensor mounted on a spreader for handling articles of a rectangular parallelepiped shape for detecting elements in plate form attached to both sides of such handling articles and both sides of the handling article loading and unloading bed of freight cars and trucks for conveying such handling articles, in order to position the spreader by detecting the detecting plate by the sensor. The sensor detects the deflections of the spreader with respect to the detecting plate, and the spreader is slightly moved for correcting the deflections so as to accurately position the spreader with respect to the article or the bed of a freight car or a truck.
