Importance of Construction Hoist Safety

For all industries, safety work must be done well. For high-risk operations such as construction elevators, it must not be neglected. According to surveys, the results show that overloading is one of the main causes of construction elevator accidents. Today we will discuss how to improve the safety performance of construction elevators from the aspect of overload protection.

How can construction hoists be used safely? This is of general concern. Only by grasping how to use construction hoists safely can safe use be ensured. So how should construction hoists be used safely? The following is a detailed analysis.

How to Use Construction Hoists Safely:

1. Construction enterprises must establish and improve various management systems for construction hoists, implement dedicated organizations and management personnel, and clarify the safety use and management responsibility systems at all levels.

2. Hoist operators shall be full-time personnel trained and qualified by the relevant administrative departments. Operation without a certificate is strictly prohibited.

3. Operators shall perform daily inspection work, that is, during the first operation of each shift, no-load and full-load trial runs shall be carried out respectively.

4. Establish and implement a regular inspection and maintenance system, conduct a comprehensive inspection of the hoist every week or every ten days, and rectify identified hidden dangers according to the "three-fixed" principle. After rectification, it can be used only after relevant personnel re-inspect and confirm that it meets safety requirements.

5. When the cage carries people or materials, the load should be distributed as evenly as possible, and overloading is strictly prohibited.

6. When the hoist runs to the top and bottom floors, it is strictly prohibited to stop it by hitting the upper and lower limit switches.

7. When the operator leaves the cage for any reason or gets off work, the cage should be lowered to the ground, the main power supply should be cut off, and the distribution box door should be locked to prevent other unlicensed personnel from starting the cage without authorization.

8. When the wind force reaches Level 6 or above, use of the hoist shall be stopped, and the cage shall be lowered to the ground.

9. Both sides of the material transport passage at each landing must have good protection. Floor doors should remain normally closed, and their height should meet specification requirements. No one may open them without authorization or put their head out of the door. When a floor door is not closed, the operator must not start the elevator.

10. Ensure that the communication device is in good condition. The operator should start the hoist only after confirming the signal. During operation, no matter who sends an emergency stop signal from a floor, the operator must immediately comply.

11. The hoist shall be separately installed with grounding protection and lightning protection devices in accordance with regulations.

How can construction hoists be used safely? It is strictly prohibited to carry out repair and maintenance work while the hoist is running. If repair is needed, the power supply must be cut off, and a sign reading "Maintenance in progress, do not switch on" must be hung in a conspicuous place, with a dedicated person supervising.

First, we generally all understand that a construction elevator has its own rated load. If the goods being transported exceed the rated load, we call it overload. Overload will make the construction elevator work under overload. When the construction elevator cannot bear it, a falling accident will occur. This is the reason why overload causes construction elevator accidents, and overload is often caused by construction personnel's weak safety awareness.

In doing any work, we must first be responsible for our own safety and that of others. Therefore, we recommend that construction elevators be equipped with overload protection devices. This is because an overload protection device for a construction elevator can automatically determine the weight of the goods. If the construction elevator is overloaded, it will send a signal alarm to the operator, thereby eliminating the danger of construction elevator overload. If an overload protection device is not installed, the weight of the goods is judged only based on so-called experience, which can easily lead to misjudgment, causing construction elevator overload and thus accidents.
