Title An intuitive control box for overhead travelling cranes
Original title Une boîte de commande intuitive pour la conduite des ponts roulants [in French]
Bibliographic information May 1972, No.5, p.262-266. Illus.
Abstract Conventional push-button control boxes are poorly suited to controlling overhead travelling cranes from the ground. The system developed by the French National Research and Safety Institute makes use of the operator's instinctive and intuitive reactions, even though he has not been taught how to use the controls. The control box is operated by a single hand. No matter what the operator's position, actuation of a given key will always produce the same load movement. To move the load in a given direction, the operator actuates the control device in the same direction. The orientation of the box in relation to the hoisting equipment is held constant by the non-twist suspension - the box is shaped like an elongated prism with an octagonal cross-section and contains the contacts; the pyramid-shaped hollow base contains 4 keys which control travel and a vertically displaceable disc for raising and lowering.
