The tilt brake can be activated from both sides of the crane by
moving the brake wheel as labeled. To tight it from the left side needs
to be turned clockwise, from the right side, counterclockwise. It is also
a brake pad system that holds the crane in place by friction.
2.3.2 ENCODERS IN THE FULCRUM
Both Pan and Tilt movements are measured by encoders which are
connected via a belt to the Fulcrum. When the crane is moved in any
of Pan or Tilt axes, the encoders receive this information and send
the gathered information to the electronic box by cable.
The Pan encoder is in the right side of the fulcrum and the color of
the connector for this encoder is grey. The pan belt is tight using the
encoder itself as a tensor. There are 4 slotted holes in the encoder
itself to slide it in or out and apply more or less tension.
The tilt encoder is located also in the right side of the fulcrum. The
color of the encoder connector is blue and to have access to the
encoder belt the cover needs to be removed by unscrewing 6 screws.
Once there is access to the belt, it can be tight also using the 4
slotted holes in the encoder. Just loose the screws holding the
encoder and slide it in or out to apply more tension.
To replace the tilt encoder belt, completely remove the tilt encoder
by losing the 4 screws that hold it and it will be possible to remove the
belt easily.
To have access to the Pan encoder belt different parts needs to be
dismounted from the fulcrum. The first thing to be dismounted is the
encoder by removing the 4 screws that hold it in place (fig. 02.35).
Then the Pan brake needs to be dismounted by unscrewing the knob
completely and removing the 2 screws aside the knob (fig. 02.33).
Once the pan encoder and the pan brake are disassembled, the arm
needs to be dismounted from the fulcrum by losing the 12 screws (6
per side shown in the fig. 02.31) and pulling it out. Then remove the
protection cover in the middle of the fulcrum (fig. 02.38). From here
there will be access to the 8 screws that holds the structure to the
main pan bushing and by removing the fulcrum, it will be possible to
access to the belt to change the pan encoder belt.
