The elevator flights may contact the cutting edge when the floor is in the full forward position. The resulting shock load of the contact can cause severe damage to the mounting flanges of the elevator speed reducer.Solution:
Perform the following steps in order to minimize the possibility of damage to the elevator drive system. 1. Maintain the correct amount of elevator chain slack.2. Increase the gap between the elevator flights and the cutting edge by increasing the number of shims on the top of the downstop supports. Spare shims are attached to the bottom of each downstop support. 3. Do not close the floor while the elevator chain is running in the reverse direction. If it is necessary to run the elevator in reverse in order to clean the chains, turn the elevator system off before returning the ejector and floor to the loading positionCOPYRIGHT 2001 CATERPILLAR ALL RIGHTS RESERVED
