8.11.PIN LOCKING BOLTS AND NUTS
Fig. 26 Flange
All the pins used on the platform were treated against wear and are fitted with
flanges to prevent them from rotating inside their seat. Some pins have bolts to
stop rotation while others pins have a joint in the structure of the machine. The
pins in the most delicate positions are threaded at the ends and are fitted with self
locking nuts or self locking threaded ring nuts to prevent the structure from sub‐
siding. Check the correct tightness of all the pin locking devices according to the
intervals indicated by the manufacturer of the machine.
Never loosen the pin locking devices and periodically check they are
correctly tightened. A pin that comes off its housing, even partially,
may cause unexpected and uncontrollable movements and even cause
the machine to lose stability and/or the basket to fall.
