Regular inspection and maintenance help keep an EVLK Series E‑LIFT™ Electric Chain Hoist safe and reliable. This article covers routine checks, load-chain care, and conditions that require qualified service.
For normal operation, see Operating an EVLK Electric Chain Hoist Safely. For product information and available configurations, see EVLK Series E‑LIFT™ Electric Chain Hoists.
Safety Notice: Before performing maintenance that requires access to the hoist, remove the load, isolate the electrical supply, and follow site lockout/tagout procedures. Only Ingersoll Rand-trained or otherwise qualified personnel should perform internal maintenance or repair.
Before You Begin
Use appropriate lighting, personal protective equipment, and the inspection records required by your site.
Before inspecting the hoist:
- Lower and support any load.
- Keep the work area clear.
- Isolate power before accessing electrical, brake, gearbox, or internal components.
- Do not operate the hoist if a safety concern is identified during inspection.
Inspect Before Each Shift
For hoists in continuous service, complete frequent checks at the beginning of each shift. Also observe the hoist during normal operation for damage or signs of malfunction.
Check the following:
- Operation: Listen for unusual noise, grinding, vibration, or chain binding.
- Load chain: Check for twists, kinks, corrosion, damaged links, insufficient lubrication, improper feeding, or foreign material.
- Hooks and hook latches: Check for cracks, deformation, wear, damage, or a latch that does not close correctly.
- Pendant and cables: Check for damaged insulation, loose connections, damaged buttons, or an Emergency Stop that does not function correctly.
- Chain bucket: Confirm that it is secure and that the chain enters without binding.
- Trolley and support components: Check visible wheels, brackets, suspension connections, and beam contact points for damage or looseness.
- Limit switches: Confirm that the upper and lower travel limits operate correctly during approved functional checks.
Remove the hoist from service if the chain binds, jumps, makes unusual noise, or does not feed correctly.
Lubricate the Load Chain
The load chain must remain lubricated along its full length. Lubrication helps protect the internal contacting and rubbing surfaces of the chain links.
- Remove the load and place the hoist in a safe condition.
- Inspect the chain for damage before applying lubricant.
- Apply an approved creeping gear oil to the full length of the chain, including the contact surfaces between links.
- Use a lubricant equivalent to ISO VG460, unless the applicable product manual or site procedure specifies otherwise.
- Run the chain slowly through its travel, when safe to do so, to distribute lubricant and confirm smooth feeding.
Do not operate the hoist if the chain remains dry, binds, jumps, or shows damage. Do not use a damaged chain or a non-genuine replacement chain.
Perform Monthly Inspection
At least monthly, or more often in demanding operating conditions, inspect the hoist and connected trolley for wear, corrosion, damage, and loose connections.
Check the following:
- Fastener tightness throughout the hoist and trolley assembly
- Pendant-control contacts and terminals for damage, corrosion, or loose connections
- Power and control cables for broken wires, damaged insulation, and loose or corroded terminals
- Electrical terminal boards and visible connections
- Trolley wheel treads, flanges, bearings, gears, and pinion components
- Trolley load plate, upper-hook connection, and suspension components
- Collector or power-supply system, when installed
- Motorized-trolley brake condition and operation
Increase inspection frequency when the hoist is exposed to heavy use, moisture, corrosive conditions, dust, or other adverse environments.
Inspect Hooks and Load-Support Components
Inspect upper and lower hooks for cracks, deformation, and wear. Remove the hoist from service if a hook is cracked, deformed, or worn beyond the limits in the applicable product manual.
Replace a hook if wear exceeds 5% of its original dimension. Do not attempt to straighten, weld, or modify a hook.
Also inspect:
- Hook latches
- Hook blocks
- Chain-end connections
- Attached rigging and handling devices
- Trolley and support-structure connections
Maintain the Trolley and Travel Components
For a trolley-mounted hoist:
- Keep the hoist centered beneath the trolley.
- Check that trolley side plates remain parallel and vertical.
- Inspect wheel clearance and beam contact for abnormal wear.
- Verify that beam end stops are in place.
- Check that the trolley moves smoothly through the full approved travel range.
- Inspect motorized-trolley wiring, controls, and braking function when applicable.
When to Contact Service
Stop using the hoist and contact qualified service personnel if you find:
- Damaged, twisted, stretched, corroded, or improperly feeding load chain
- Cracked, deformed, or excessively worn hooks
- A damaged hook latch, pendant, cable, chain bucket, trolley, or support connection
- Grinding, abnormal noise, vibration, overheating, or load drift
- An Emergency Stop or limit switch that does not function correctly
- Damaged electrical connections, enclosures, or cable insulation
- Evidence of brake, gearbox, motor, overload-protection, or internal electrical problems
For safe first-level diagnosis, see Troubleshooting Common EVLK Electric Chain Hoist Problems. Internal service, brake work, electrical repair, chain replacement, and component replacement must be performed by authorized personnel.
