Lady Pendant Station
The new LADY series single-row push-button stations for auxiliary circuits are the result of a blend of Ravioli’s long experience in the field, detailed studies in ergonomics, and the use of innovative, modern design and materials, in compliance with the best technology available today. In designing the product particular attention was paid both to easy handling features and to the technical aspects, in order to ensure usage also in heavy-duty circumstances. All the materials, which come into direct contact with the environment, are resistant to atmospheric agents, oils, temperature changes and are shockproof.
The rubber gaskets ensure optimal protection against dust and liquids. The optimised internal space allows to make all connections easily and quickly. Bridge connections have been projected in order to reduce cabling time and are available upon request. LADY push-button station is offered in 6 different sizes, ranging from 2 to 12 buttons devices and various controls and switches can be mounted on each type. LAP versions for bridge cranes and hoists and LAE for building cranes are available. The emergency stop push-button has been designed in according to EN 418 regulations.
The NC contacts feature guaranteed opening (EN 60947-5-1) and can be supplied also in the 2NC increased safety version. All buttons are marked with international symbols. The switches have self-cleaning sliding contacts in silver alloy.
