DANGER !
To avoid personal injury or death, before performing any static inspections,
make sure the platform carriage is fully lowered and the power has been
disconnected at the safety disconnect switch. Also, put signs at all gates,
doors, controls, etc. indicating that the system is out of service for
maintenance per OSHA Lock-Out, Tag-Out procedures.
Inspection List – Every 3 Months (1,000-1,200 hours of operation):
1. Inspect cables for damage, unusual wear, or fraying
2. Inspect sheaves for bending or binding, ensure cable runs smoothly in sheaves
and that sheaves rotate freely
3. Inspect carriage guide rollers for wear, binding, or other indication of non-rotation
4. Inspect all gate/door interlocks and status switches for proper operation
6. Inspect all gates/doors for wear or damage
7. Look for any unusual rub marks on the guides, wall, platform carriage, masts, etc,
which might indicate misalignment of the components due to overloading, misuse,
or something out of tolerance.
5. Check that the cylinder is clean and un-nicked. There may be a small amount of
oil accumulating near the rod clevis block and around the rod seal due to the
normal wiping action of the rod wiper. Wipe the area clean.
NOTE
: Do not mistake normal lubricating weeping for a leak. If oil is running
down the outside of the cylinder barrel and is dripping on the floor after
everything has been wiped clean during the last maintenance, there may be a
rod seal or a bleed screw leak.
Inspection List – Every 6 Months (2,000-2,500 hours of operation):
1. Inspect all cable sheaves for wear or damage
2. Make sure that the platform carriage is lined up with the upper floor. Adjust the
stop bolts, if required.
3. Check that the platform carriage is actuating the limit switches correctly (for gates
with solenoid interlocks). Adjust limit switch arms, if required, per procedure in the
“Installation” section.
4. Thoroughly inspect all Locking Cam assemblies, immediately replace any
components which exhibit excessive wear, including but not limited to:
a. Locking Cam – any tooth edge which feels rounded or flattened in any way
NOTE: Locking cams are a critical component in the free-fall arrest
safety system and become less effective after multiple engagements.
Wheel guides / locking cams should be replaced after being engaged
under full or partial load more than twice.
