There are many safety hazards in the operation and maintenance of low clearance electric hoists, and targeted solutions need to be taken to ensure safe operation. The following are specific instructions:

potential safety hazard

Overloaded homework

Users may overload their devices in pursuit of efficiency, resulting in structural damage or even breakage.

Violation of regulations such as diagonal pulling and lifting can exacerbate the wear of steel wire ropes and increase the risk of breakage.

Improper environment and operation

When working in dim environments, it is difficult for operators to see the site and command signals clearly, which can easily lead to collision or falling accidents.

Loose binding and hanging, or lack of padding on the edges and corners of heavy objects, can cause the goods to slip or the steel wire rope to break during the lifting process.

Equipment defects and damage

Defects such as brake failure and damage to the anti loosening device of the hook nut can directly threaten the safety of lifting.

Continuing to use steel wire ropes that have reached the scrap standard due to wear and breakage can easily lead to fracture accidents.

Electrical and control system malfunction

The failure of limiters, disconnection of control circuits, and other issues can lead to equipment loss of control or excessive operation.

The detachment of motor protective casing and exposure of electrical components may cause electric shock accidents.

Solution

Strengthen the training and assessment of operators

Develop a training plan and conduct professional training on low clearance electric hoists at least once a quarter, covering operating procedures, safety knowledge, troubleshooting, etc.

Only qualified personnel can take up their posts after evaluating the training effectiveness through assessment, ensuring that the operators have the necessary knowledge and skills.

Regular equipment maintenance and overhaul

Conduct equipment inspection and maintenance once a month, with a focus on key components such as brakes, hooks, and wire ropes.

The maintenance process should be documented, and any problems should be promptly reported and addressed to ensure that the equipment is in good condition.

Optimize the working environment

Set up a dedicated low clearance electric hoist operation area at the construction site to ensure that there are no obstacles in the operation area.

Set up clear safety warning signs in the work area to remind personnel to pay attention to safety.

Improve safety protection measures

Equip safety nets, guardrails, and other protective equipment to ensure the safety of operators.

Assign a dedicated person as a safety observer during the operation process to monitor the work situation, promptly identify and address potential safety hazards.

Develop emergency response plans for accidents

Regularly organize emergency drills to improve employees' ability to respond to sudden accidents.

Establish a feedback mechanism, promptly summarize and analyze accidents, and improve emergency plans.

Strengthen equipment security design

Adopting safety devices such as overload limiters and lifting limiters to prevent overloading and over limit operation.

Waterproof and dustproof treatment should be carried out on electrical components to improve the protection level of equipment.

Standardize operational procedures

Overloading, diagonal pulling, and other illegal operations are strictly prohibited.

Ensure firmness and reliability when bundling and hanging, and add padding to protect the edges and corners of heavy objects.

Before operation, check whether all components of the equipment are intact and confirm that there are no errors before starting.
