To properly secure a load for an electric hoist, you must use the correct slings and attachments for the specific object being lifted. The core of the process involves ensuring the hook and upper suspension are in a perfectly straight line above the load's center of gravity and confirming the hoist's chain or body will not make contact with the load during the lift.
Securing a load is not just about the final connection; it is a systematic process that includes rigorous pre-lift inspections, precise rigging techniques, and a disciplined operational environment to ensure total safety.
The Pre-Lift Inspection Checklist
Before you attempt to attach any load, a thorough inspection is a non-negotiable safety requirement. This prevents equipment failure before the lift even begins.
Inspect the Hoist and Attachments
Your first step is a visual check of all components. Look for any signs of damage on the hooks, cables, and chain.
Specifically, search for scratches, dents, cracks, twists, or throat deformation. Pay close attention to saddle and bearing wear, as these are critical failure points.
Verify Lubrication
Proper lubrication is essential for smooth and safe operation. Ensure all links of the hoist chain are fully lubricated before you begin work.
Confirm Load Capacity
Never assume the hoist is rated for the job. You must know the weight of the load and confirm it is well within the hoist's specified maximum capacity to prevent overloading.
Locate and Identify Safety Controls
Before any operation, all workers involved must know the precise location of emergency shutoff buttons and any other safety switches. This knowledge is critical in an emergency.
The Rigging and Attachment Process
Once inspections are complete, you can proceed with the physical attachment of the load. This stage requires precision to ensure stability.
Select the Right Gear
Use the appropriate slings, hooks, or lifters designed for the shape and weight of your specific load. A mismatched attachment is a primary cause of slippage.
Ensure Proper Vertical Alignment
The single most important principle of rigging is vertical alignment. The hoist hook and its upper suspension must form a straight, vertical line directly over the load's center of gravity.
Any offset will cause the load to swing dangerously as soon as it leaves the ground.
Prevent Contact with the Hoist
Maneuver the rigging so that the hoist's chain or main body cannot rub against or get caught on the load itself. This contact can damage both the hoist and the load.
Executing the Lift Safely
With the load secured, the focus shifts to a controlled and aware operational procedure.
Perform a Test Lift
Before committing to the full lift, raise the load just a few inches off the ground. Pause and check that the rigging is secure, the load is balanced, and it is not tilting or shifting.
Maintain a Clear Zone
No personnel should ever stand under or in the immediate vicinity of a suspended load. The operator must ensure the entire lift path is clear of people and obstructions.
Use Clear Communication
The hoist operator and any ground personnel must use prearranged and clearly understood signals or gestures. This eliminates confusion during the operation.
Manage the Wire Rope
If using a wire rope hoist, you must ensure that at least three full loops of wire rope remain on the hoist drum at all times, even at the lowest point of the lift.
Common Pitfalls to Avoid
Understanding common mistakes is key to developing a robust safety culture. Avoiding these simple errors can prevent most lifting accidents.
Overlooking Wear and Tear
Skipping pre-lift inspections out of habit or haste is a critical error. A small crack or sign of wear can quickly escalate to catastrophic failure under load.
Misjudging the Center of Gravity
Failure to achieve proper vertical alignment is the most common cause of load swings. This puts immense stress on the equipment and endangers everyone in the area.
Neglecting the Test Lift
The small pause required for a test lift seems minor, but it is your final opportunity to catch rigging errors, imbalanced loads, or potential snags before the load is at a dangerous height.
Making the Right Choice for Your Goal
Your operational focus will determine which safety checks are most critical.
- If your primary focus is personnel safety: Prioritize a rigorously enforced clear zone and ensure all operators are trained on emergency stop procedures.
- If your primary focus is equipment longevity: Emphasize daily inspections for wear, consistent lubrication, and never exceeding the rated load capacity.
- If your primary focus is operational integrity: Make the test lift a mandatory, unskippable step in every single lifting procedure.
Ultimately, a disciplined and methodical approach is the only way to guarantee a safe and successful lift.
Summary Table:
| Safety Step | Key Action | Purpose |
|---|---|---|
| Pre-Lift Inspection | Check hoist, hooks, chain/cable for damage; verify lubrication and load capacity. | Prevent equipment failure before the lift begins. |
| Rigging & Attachment | Use correct slings; align hook directly over the load's center of gravity. | Ensure load stability and prevent dangerous swinging. |
| Safe Execution | Perform a test lift; maintain a clear zone; use clear communication. | Catch errors early and protect personnel during the operation. |
