Project Safety | How to prevent lifting and lifting accidents?

release time:


The use of lifting and hoisting operations is common in production, but due to the complex working environment and technical difficulties, it is more prone to safety accidents. Once an accident occurs, it is truly shocking. Let me show you a series of accident scene animations:

Every accident happens in an instant, and each one is shocking and unbearable to witness. We must deeply learn from the experience and lessons of accidents, and understand the safety risks and how to avoid them when operating lifting operations.

Security risks

Lifting operations have always been a relatively dangerous profession. The site has so much uncertainties, including outdoor work, crossing operation, night work, work at height, etc. Different operations have different risks:

1 Outdoor work

Due to weather changes and other factors, there may be strong winds, thunderstorms, heavy fog and other weather conditions , affecting the thinking and judgment of lifting operators, unclear command signals, and causing lifting injuries.

2 Crossing operation,

If we don't take proper precautions and reach an agreement with our colleagues from other departments in a timely manner, there is a high risk of experiencing accidents such as being hit by objects or getting injured while lifting heavy objects.

3 Night construction

 Factors such as inadequate lighting and fatigue among the lifting operators can easily lead to lifting injuries.

4 Working at heights

It is important to have safety measures in place to prevent accidents like falling from heights or being struck by objects.

Safe Operation Guidelines

In order to prevent the risks of lifting operations, the following is a guide to the safe operation requirements for lifting operations:

1. Rigging plan:

Special construction plans for rigging and hoisting should be prepared, reviewed, and approved. Over the scale of rigging and hoisting special construction programme, should be in accordance with the provisions of the organization of expert testimony.

2. Load limit:

Lifting machinery should be equipped with load limit devices and travel limit devices, which should be sensitive and reliable. The assembly of lifting rods should meet the design requirements, and after assembly, the acceptance procedure should be followed, with the responsible person's signature on the acceptance form.

3. The rigging meets the requirements:

The specifications of the wire rope should meet the requirements stated in the crane's product manual. Wear, broken wires, deformations, and rust should be within the allowable range specified by the regulations.


The wear of the hooks, reels, and pulleys should also be within the allowable range specified by the regulations.


Hooks, reels, and pulleys should be equipped with wire rope anti-detachment devices.


The setting of the rigging pole's cable wind ropes and ground anchors should meet the design requirements.


The safety factor of the rigging should comply with the requirements of the regulations.


The specifications of the slings should be matched, and their mechanical performance should meet the design requirements.

4. The connection meets the requirements:

When using sling connections, the length of the sling should meet the requirements of the regulations.


When using rope clip connections, the specifications, quantity, and spacing of the rope clips should meet the requirements of the regulations.

5. Crane requirements:

The ground bearing capacity at the working area of the crane should meet the requirements stated in the product manual; the safe distance between the crane and overhead power lines should meet the requirements of the regulations.

6. Personel requirements:

Crane operators are required to have a valid certification that matches the type of crane they operate.


Dedicated personnel for signaling and rigging should be assigned for crane lifting operations.


Before starting any work, a safety briefing should be conducted according to regulations, and a written record should be created.

7. Rigging process:

When multiple cranes lift a component simultaneously, each individual crane must meet the load requirements outlined in the special construction programme.

The tethering point for the sling used to lift the component must also meet the special construction programme's requirements.

It is strictly prohibited for individuals to remain underneath the crane's lifting arm while it is in operation, and the lifted weight must not pass directly over any individuals.

The crane spreader is not to be used for personnel lifting.

The crane spreader is not to be used for personnel lifting. The crane spreader is not to be used for personnel lifting. Objects prone to falling apart should be lifted using a crane cage.

8. Work at height:

Lifting and hoisting operations must comply with the elevated work platform provisions and specifications.

Climbing ladders must conform to lifting and hoisting regulations and meet the required strength and structural criteria.

9. Components stacked load

It should fall within the acceptable range of the working surface's bearing capacity, while the stacked height should comply with regulations. When stacking significant components, measures must be taken to guarantee stability.

10. Operation cordon zone

The designated operational cordon zone must be established as instructed, and oversight of the cordon zone must be conducted by an individual.

By following the safety guidelines, the project's risk of construction-related accidents will be significantly reduced.
