2.23 AXLE DRAIN PLATES
The electric boom lifts are equipped with two maze-type
water drains, located on the underside of the axle box.
This ‘S’ type drain arrangement is required to meet EE rat-
ing, although dust and debris can accumulate and clog
these drains, trapping water inside the axle box. Periodi-
cally check and open drains with compressed air, or
remove and clean them if necessary.
