3.10 PIN LOCKING BOLTS AND NUTS
All the pins used on the JLG platform were treated against wear and are fitted with flanges
(1) to prevent them from rotating inside their seat. Some pins have bolts to stop rotation (2)
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 (3) or self‑locking threaded ring nuts to prevent the structure from subsiding.
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.
3.11 SAFETY DEVICE ELECTRONIC CONTROL BOARD
The JLG platform has an electronic control board (see
photo) that enables the power supply to the ON‑OFF pro‑
portional coils after verification of the safety conditions by
the sensors positioned on the machine.
The control procedure on the electronic board may be
bypassed using the key selector switch with spring return:
“safety device bypass key”.
The electronic board records every bypass action carried
out by the operator on the safety devices, filing them by
date, time and lapse of time during which the operator held the “safety device bypass key”
in position.
The board is also provided with an event record that stores all the operations performed on
the machine for a variable period of time.
