2.2 COLUMN
The SCORPIO cranes´ arm is supported by a telescopic column. This column can be lifted or
retracted automatically with the Hand Command of the crane depending on the operator’s need. The
column of the SCORPIO 45’ is made up of three sections: A main column fix and two telescopic
sections inside of it. The SCORPIO 38’ has only two sections: One fix and one telescopic.
The column is attached to the dolly using 4 screws (DIN912
M20x50mm) in the platform. There is a guiding hole in the base of
the column to align the column with the pin in the dolly.
In case the column is not mounted in the dolly, it can rest in the 4
legs located under it without damaging the mechanism for the motor
of the column.
At the bottom of the column there is a motor attached to a gearbox
through a belt. When the motor moves, the belt transmits this
movement into the gearbox that moves the endless screw inside the
column and pulls the telescopic sections up or down. To tight this belt,
the 4 screws from the picture can be loosen and the block of the motor
can be displaced to apply the proper tension to the belt. To replace
the belt, lose it until there is no tension on it and the belt can be pulled
out.
• Commercial reference for Column motor belt: 5M 665
Once the column is assembled into the dolly with the column screws
it can be lifted manually or with the Hand Command. Notice that all
the triangular sides of the column are threaded at M10 to attach any
support that the customer needs without interfering in the proper
function of the crane.
Also notice that the connector for the column motor is accessible
from one side of the column.
