When lifting a lever chain hoist, the following aspects should be paid attention to to ensure safety and efficiency:
1. Pre-use Inspection
Mechanical Integrity: Check for any damage to the hook, chain, axles, or other components. Ensure that pins are secure and that the transmission mechanism operates smoothly without signs of wear, slippage, or jamming.
Chain Condition: Examine the chain for twists, kinks, or damage. If any issues are found, correct them before use. The chain should be free of rust, cracks, or excessive wear.
Brake System: Verify that the brake is reliable and functions correctly. The brake should engage securely when the load is lifted and release smoothly when lowering.
Load Capacity: Confirm that the load being lifted does not exceed the rated capacity of the hoist. Overloading can lead to equipment failure or accidents.
Mounting Stability: Ensure that the hoist is securely mounted or hung from a stable structure. The support must be capable of bearing the full weight of the load without risk of collapse.
2. Proper Operation Techniques
Initial Setup:
Place the selector switch in the neutral position and pull out the handwheel to engage "free-wheel" mode. This allows manual positioning of the bottom hook before lifting.
Center the load properly on the bottom hook to maintain balance and prevent tilting.
Lifting:
Gradually pull the load chain to lift the load. Avoid sudden or jerky movements, which can cause instability or damage to the hoist.
Keep the load vertical during lifting. Avoid side pulling or lifting at an angle, as this places undue stress on the hoist and reduces its lifting capacity.
Lowering:
To lower the load, turn the selector switch to the "DOWN" position and ratchet the handle smoothly. Ensure that the load is controlled throughout the descent to prevent sudden drops.
Load Suspension:
If the load needs to remain suspended for an extended period, secure the hand chain to the load chain to prevent accidental release due to brake failure.
3. Safety Precautions During Use
Avoid Standing Under Loads: Never stand directly beneath a suspended load. In the event of equipment failure, the load could fall, causing serious injury or death.
No Extensions on Lever Handle: Do not use any extensions or tools to increase the length of the lever handle. This can lead to excessive force application, potentially damaging the hoist or causing loss of control.
No Foot Pressure on Lever Handle: Avoid applying pressure to the lever handle with your foot. This can result in uneven force distribution and loss of balance, increasing the risk of accidents.
Prohibit Overloading: Overloading is strictly prohibited. Always adhere to the rated load capacity of the hoist. If the load weight is uncertain, use appropriate methods to determine it before lifting.
No Pulling on Handwheel During Operation: Do not touch or pull on the handwheel while the hoist is lifting or lowering a load. This can interfere with the normal operation of the hoist and lead to malfunctions.
Prevent Free-Wheel Mode with Load: Do not operate the hoist in "free-wheel" mode when there is a load attached. This can cause the load to drop unexpectedly, posing a significant safety hazard.
4. Teamwork and Communication
Clear Communication: When multiple personnel are involved in the lifting operation, ensure clear and effective communication. Use standardized signals or communication devices to coordinate actions and prevent misunderstandings.
Synchronized Operation: If multiple hoists are used simultaneously to lift a single load, ensure that all hoists are of the same capacity and that the load is evenly distributed. Operate the hoists in sync to maintain balance and prevent overloading of individual units.
5. Post-use Maintenance
Regular Lubrication: Apply lubricant to the rotating parts of the hoist, such as gears and bearings, to reduce friction and wear. However, avoid getting lubricant on the friction surfaces of the brake system, as this can reduce braking effectiveness.
Chain Care: Prevent the chain from rusting by storing the hoist in a dry, clean environment. If the chain shows signs of severe rust, cracks, or excessive wear, replace it immediately. Do not continue using a damaged chain.
Storage: Store the hoist in a designated area where it is protected from moisture, dust, and physical damage. Hang the hoist or place it on a rack to prevent the chain from becoming tangled or damaged.
