J. LEVELING THE CARRIAGE (Reference Figure 34)
WARNING !
When running the unit before ALL limit switches are
installed, be prepared to disconnect power on demand. Allowing carriage
overtravel in either direction can result in severe damage to the equipment
and potential injury to standers-by. Temporary power must NOT be used.
1. Make sure the carriage is free to rise about six (6) inches. Check to be sure carriage
is level and chains are equally tight.
2. Continue to raise carriage in small six (6) inch increments, checking for binding or
interference. Make any changes necessary to align beams to allow smooth travel.
3. Stop carriage at upper level and check to make sure it is level and that there are the
same number of chain links between the wheel guides & lifting sprockets. DO NOT
attempt to tighten or loosen chain with the carriage in the raised position.
4. Adjustments to lifting chain tension can be made by loosening the four (4) 1/2" x 2”
bolts attaching the carriage uprights to the wheel guide, then tightening or loosening
chain tension with the 1/2" x 5” bolt on top of each carriage upright (refer to Figure
34). Once the chain is tightened/adjusted as needed, re-tighten the four (4) attaching
bolts to 99 ft-lbs.
5. Lower the carriage in small increments. Watch again for adequate clearance
throughout the travel, checking for interference or binding of the chain and carriage.
6. When complete, tighten all mast foot plate bolts to 99 ft-lbs..
CAUTION!
All chains must be fully engaged with the teeth of all chain sprockets
before operation begins. Chains which jump the sprockets during
tensioning can cause permanent damage to the lift
