from its normal appearance, must be replaced. If any cable is found to be in need of
replacement, the entire cable set must be replaced immediately. Refer to figures below.
4. Sheaves: Check sheaves (pulleys) for wear or damage, i.e. wobble (tilt), cracks, loose on
pin, or excessive noise during operation.
5. Sheave Pins: Check for loose or missing sheave (pulley) pins.
6. Locking Latches and Slack Cable Devices: Watch locking latches and slack cable devices
during lift operation to ensure that latches work properly and line up with slots in latch plate
located in columns.
Monthly Inspection & Maintenance
1. Cables
1.1 Clean wire rope cables with lift in both lowered and raised position by spraying with
Penetrating Oil and wiping the cable down.
1.2 Adjust cables using procedures on following pages.
2. Slack Cable Device: Inspect slack cable devices using procedure on page 5.
3. Column Anchor Bolts: Check column anchor bolts for tightness. Re-torque anchors bolts to
65 ft/lbs. If anchors do not tighten to the required installation torque, replace concrete under
each column base per installation instructions. Let concrete cure before installing lifts and
anchors.
4. Columns: Look for corrosion, giving special attention to the area at the base of the column.
Check severely corroded areas by pecking with an awl or welder’s chipping hammer. If column
is corroded through at any point it must be replaced immediately. If not corroded through,
remove old paint and rust scale, then coat with a high quality corrosion resistant paint.
A thorough inspection of the lifting system must be performed quarterly by qualified lift
service personnel; more frequently (monthly) under extreme service conditions such as outside
installations or high usage (10 or more cycles per day, etc.).
Quarterly Inspection & Maintenance
1. Cables
1.1 Inspect cables in both lowered and raised position. The cables may also be viewed
through various inspection holes and openings in yokes and runways. Check all the following:
a. That cables have no broken wires visible, reference Daily Inspection & Maintenance.
b. That cables are free of severe corrosion and pitting, reference Daily Inspection &
Maintenance. A light surface corrosion on exposed outer wires is normal. Penetrating
Oil should be applied during monthly periodic inspection.
c. That there are no areas on the cable that have a greatly reduced diameter or “necking”,
reference Daily Inspection & Maintenance. When any cable is found with excessive
necking, all cables must be replaced immediately.
