Potain Igo T85A (27148) – Weathervane light does not come on
Even though the actuator weathervanes the crane, the light does not come on. There is a microswitch on the back of the slew motor. Proper adjust by the manual would require removing the slew motor. For a field fix, remove the cover (see previous post for proper removal). With the cover removed, take crane out of weathervane (slew brake set). There is an adjustable plate that contacts the microswitch when activated. Loosen the screw with a 8mm wrench and pull the contact plate up towards the microswitch. Tighten slightly more than finger tight. Activate the weathervane and verify the light comes on. If it comes on, take the crane out of weathervane and tighten completely. Replace cover as outlined in the previous post.
Potain Hup 40-30 (22131) – Does not allow for validation for mast locks
When towering up, mast locks are extended but the orange validation button does not appear. S934S does not close. Jumper 24 VDC to G5 and horn honks and validation button appears. Mast lock switches should look like this (folio 11):
Mast locks extended:
S933S 0 (open)
S934S 1 (closed
Mast locks retracted:
S933S 1(closed)
S934S 0 (open)
Will update once crane is down and switches are tested
