Bogie and Axle Drop Plants
There are three different types of Bogie Drop Systems.
The first is a a big pit or underfloor tunnel and machine that has a scissor lifting device or a screw lifting system.
The second is a medium pit and machine that contains a screw lifting system.
The last has no pit but has a screw lifting system .
Depending on the type of train only two supports are need for the coach. The movable frame for the “no pit” type is a steel frame with four lifting points and four Steel Wheels that can be removed laterally. The length of the frame allows the person operating the system to remove the modules that are fixed under the coach of the train using a special interface. The Bertolotti Patent does no require particular civil works. It has been designed to be installed in a depot by only cutting the rail in the position where the plant has to be installed using four small holes for the columns.
