Potain IGO T85A – Page 6 – Service

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 Igo T85A (27148) – Greaser not working

Amber light on the control panel with grease symbol on, but grease reservoir full.

Light comes on when it’s working, and when grease level is low. Grease pump motor is 24 volts DC. Found 8 volts. Removed 3 pump bolts and water poured out. Circuit board was shorted. Replace assembly.

(Note. K600M must be engaged to activate greaser circuit.)

Operator complaining that the crane is kicking off when hoisting. Determined it is only in 3rd speed. Hoist speed sensor needs to be adjusted and the end of shaft needs to be cleaned of debris.
