Fassi cranes used to work on railway lines can be fitted on various types of rolling stock, such as trucks, locomotives, wagons with dual driving system for road and rail use.
To assist the work of operators in yards and along railway lines, cranes are fitted with special devices aimed above all at preventing accidental contact with overhead power lines (chain links).
OTHER SUPPLEMENTARY DEVICES
Management of rotation with dual proximity sensor, to avoid use of the crane in areas where there are trains in transit, and key selector to determine the working side.
The Fassi railway cranes
Fassi has gained significant experience in the railway cranes field, based on the attention that the Fassi engineering department has been dedicating to the development of cranes for this specific application. Appropriate arrangements were made to enable the installation of standard cranes, designed for trucks, on rail vehicles, without distorting the typology or prices with machines developed specifically to this purpose, as it may happen on the market. Cranes operating on rail vehicles have to be equipped with additional safety devices for rotation and height limitation not required by cranes mounted on truck in order to be in compliance with the “operational safety” standard in presence of double-track lines or electric traction line commonly referred to as “catenary.” So devices with a removable key in a blocking position were introduced to define the geometric work areas where the crane can operate in full safety. Such devices can be summarized as: - Rotation limiter to define the angle of rotation around its vertical axis: Work area “A – B”. - height limiter to define the rotation angle of the main boom from the column. The limitation systems are normally inactive and are activated by the operator with the specific controls. They were developed with redundant equipments to ensure a safe operation.
