Hoistway Door and Operation
Adjustment. Examine each door carefully. Check for structural defects. Examine
the doors to see if they can be opened without releasing the interlock. If the lock is
worn or the door has sagged so that interlock does not engage properly, arrange for
repairs at once. Clean, lubricate and inspect all pins, bushings, guides, etc. as
needed. Be sure that bumpers are in place and in good condition.
Hangers. Examine the hangers for proper operation, wear, upthrust adjustment,
and condition of the guides (gibs) in the bottom of the doors. Checks tracks for wear
and alignment, and tighten all fastenings if needed.
Interlocks. It is extremely important that all lock failures be repaired immediately.
Check contacts and the point at which they close. Try to pull the door open with the
car outside the range of the lock. Carefully check clearances and tightness of bolts
and screws to avoid future shutdowns.
