The magnetic limits are connected in one small box located on top
of the gearbox. From there the cable for the limits is joined with the
cable from the motor to be connected into the electronic box.
2.4.1.2 COUNTERWEIGHT SUPPORTS
There are two fix supports for counterweights in the main arm, one in the front and one in the back.
These supports are used to mount counterweights on them in order to make the fix balance of the
crane (see chapter 3.2 Starting the crane).
The Back-Counterweight Holder is located at the back of the main
tube of the Crane Arm. It consists of a platform to slide the weights in
and a screw with a red locking nut that is used to fasten the different
counterweights provided with the crane in order to balance it.
The Front-Counterweight Holder is located at the front right part of
the main section. It consists of a platform to slide the weights and 2
screws with red locking nuts that are used to hold in place and fasten
the different counterweights provided with the crane in order to
balance it.
2.4.1.3 DYNAMIC COUNTERWEIGHT TROLLEY
The SCORPIO 45’ and the SCORPIO 38’ have a movable
counterweight trolley that balances the crane when the telescopic
sections retract or extend. This movable counterweight is attached to
the First section with 12 cables that work as a closed loop using a
pulley system in the front part of the main arm and a regular pulley in
the back. When the First section extends, the CW (Counterweight
carriage) moves to the back of the crane.
The weight holders on the weight carriage will be used to
counterbalance the telescopic crane arm while it´s moving. It consists
of an inverted metallic “U” that is connected to the moving carriage on
the Crane Arm. The U is fixed to the carriage with 12 screws (DIN912
M12x40mm). It has two “male” supports, one per side which fit into
the “female” part of the counterweights.
