Automotive Lift Maintenance
We want make sure you get the highest possible performance from our products, along with safety. Below, you will find a schedule of lift maintenance for you to use with your automotive lift system. By adhering to this schedule, your lift should last for a long time and you will be able to provide safe working conditions for those who use the lift. Please read these steps carefully, and make sure you understand each one.
WEEKLY PREVENTATIVE MAINTENANCE FOR AUTOMOTIVE LIFTS
- Check that mounting is correct for all cable connections, bolts and pins.
- Lubricate with general purpose oil or WD-40: All rollers and safety lock pivot points.
MONTHLY PREVENTATIVE MAINTENANCE FOR AUTOMOTIVE LIFTS
- Moving Parts and Cables: Visually inspect, checking for excessive signs of wear.
- Safety Locks: Make sure they are operating correctly and are in good condition.
- Replacements: If you discover any faulty parts, replace them before you allow the lift to be operated again.
REQUIRED MONTHLY MAINTENANCE FOR AUTO LIFTS
- Arm Adjusting Locks: Check all for proper operation.
- Pivot Arm Pins: Inspect to see that they remain secure.
- Columns: Lubricate with grease and ensure they are plumb and square.
- Equalizer Cable: Check the tension and adjust if necessary.
- All Cables: Check cable connections and inspect the cable bolts and pins to ensure proper mounting and torque.
- Overhead Cut-Off Switch (if so equipped): Check for proper operation.
- Safeties: Visually inspect to ensure they are working correctly.
- Anchor Bolts: Inspect for looseness and retighten if necessary.
WIRE ROPE INSPECTION AND LUBRICATION
- Inspection schedule: The American Petroleum Institute (API) RP54 guidelines state that lifting cables should be visually inspected at least once each day when in use.
- Lubrication: Wire cables should be well-lubricated at all times and lubricated as often as necessary to keep them that way, since wire rope is only fully protected when every single wire strand is both internally and externally fully lubricated. To this end, lubricate wire rope at intervals no longer than three months during times the lift is in operation. Excessive wear will shorten the life of the lifting cables, so you may need to lubricate them more often than that, according to your daily observations.
- Lubricants for wire cables suggested by the manufacturer penetrate to the core of the rope, providing long-term lubrication between each individual strand. 90-WT gear oil or ALMASOL (TM) Wire Rope Lubricant are preferred.
- Inspection and lubrication of sheaves and guide rollers: Any of these in contact with the moving rope should be visually checked at interval not to exceed three months, during operation of the lift. Look for surface wear. Also, lubricate these parts to ensure that they can run freely.
- Lubricants for sheaves and guide rollers: For sheave axles, use standard wheel bearing grease. For guide rollers and sheaves use 90-WT gear oil or a similar heavy lubricant. Apply the lubricants by any method, such as pump spraying, brushing, or swabbing.
WIRE ROPE REPLACEMENT
- Lifting cables should be replaced, in any case, every 3-5 years or sooner, if there are signs of damage.
- If there are 6 broken wires within any one lay length, randomly distributed, or 3 broken wires in one particular strand within one lay length, the wire rope must be replaced.
- If there is wear that exceeds 10% of the original diameter of any cable, replace it.
- If there is evidence of heat damage, replace the cable.
- If inspection reveals corrosion pitting the connectors or wires, replace those parts.
- If you see kinking, bird-caging, crushed or cut wire or a popped wire core, it's time for replacement.
- Any lifting cables that have met the criteria for removal must be immediately replaced. DO NOT USE YOUR AUTOMOTIVE LIFT WITH ANY DEFECTIVE OR WORN LIFTING CABLES.
INSPECTING A LIFT FOR BROKEN WIRES
- • Step One: Relax the cable to a stationary position.
- • Step Two: Move the pick-up points off the sheaves.
- • Step Three: Clean the surface with a cloth (or a wire brush, if necessary) This will enable you to see any breaks.
- • Step Four: Flex the rope. This should show any broken wires that are hidden between the strands.
- • Step Five: Pass a cloth along the rope to see if it is snagged by a broken wire end from a crown break.
- • Step Six: To find internal broken wires, you will need to make a more extensive rope examination. Probe between wires and strands with an awl and lift any wires that appear loose.
