When operating a chain hoist for lifting operations, it is important to pay attention to the following key aspects to ensure safe and efficient completion of lifting tasks:

1、 Preparation and inspection before lifting

Equipment status check

Chain and hook: Check whether the chain has cracks, deformations, or excessive wear, and whether the hook rotates flexibly without cracks.

Braking system: Test whether the brake is sensitive and reliable, ensuring that it can quickly stop in case of power failure or emergency.

Limit device: Confirm that safety devices such as travel limiters and overload protectors are functioning properly to avoid overloading or overtravel.

Electrical system: Check whether the cables are damaged, whether the control buttons are sensitive, and whether the grounding is good.

Assessment of homework environment

Space conditions: Ensure that there are no obstacles in the work area and no personnel or equipment obstructing the crane's movement range.

Ground bearing: Confirm that the ground or supporting structure can withstand the total weight of the crane and load to avoid the risk of collapse.

Environmental factors: Evaluate whether wind speed, temperature, etc. meet the working conditions of the equipment (such as strong winds that may affect stability).

Load assessment and fixation

Weight confirmation: Verify that the load weight does not exceed the rated load of the crane and reserve a safety margin.

Center of gravity balance: Adjust the load position to ensure the stability of the center of gravity and avoid shaking or tilting during lifting.

Fixed measures: Use appropriate lifting equipment (such as wire ropes, slings) and ensure a secure connection to prevent slipping.

2、 Lifting operation specifications

Standardization of operating procedures

Trial lifting: First, lift the load at a low speed by 10-20cm, check the braking, chain, and load status, and confirm that there are no errors before continuing.

Smooth lifting: Slowly accelerate to the working speed to avoid sudden start-up causing load shaking.

Accurate positioning: Fine tune the load position through jog operation to avoid impact caused by rapid movement.

Safe distance and avoidance

Personnel isolation: During the lifting process, personnel are prohibited from staying under the load or within the movement trajectory of the crane.

Obstacle avoidance: Maintain observation of the surrounding environment during operation and adjust the path in a timely manner to avoid obstacles.

Load monitoring and emergency response

Real time observation: Operators need to monitor the load and crane status throughout the entire process, and immediately stop the machine if any abnormalities are found.

Exception handling: In case of chain jamming, abnormal noise or brake failure, immediately press the emergency stop button and evacuate personnel.

3、 Final work after lifting

Equipment reset and inspection

Load unloading: Place the load steadily in the designated position before releasing the lifting device.

Chain return: retract the chain to the shortest effective length to avoid looseness that may cause entanglement or damage.

Equipment shutdown: Cut off the power, lock the control box to prevent accidental operation.

Maintenance and recording

Cleaning and maintenance: Remove oil and dust from the surface of the equipment, and perform rust prevention treatment on the chain.

Fault record: Record any abnormal situations during the lifting process, promptly report for maintenance, and track the handling results.

Regular maintenance: Perform maintenance work such as lubrication, fastening, and replacement of vulnerable parts according to the plan.

4、 Personnel training and qualifications

Operator Qualification

Ensure that operators hold valid certificates (such as special equipment operator certificates) and are familiar with equipment performance and safety regulations.

Cultivation of Safety Awareness

Regularly conduct safety training to enhance operators' awareness of risk points and prevent unauthorized operations.

emergency drill

Organize simulation exercises (such as sudden power outages and load drops) to enhance personnel's emergency response capabilities.

5、 Management Supervision and System

Institutional construction

Develop operating procedures, maintenance systems, and safety checklists for cranes, and clarify the division of responsibilities.

Daily supervision

Assign a dedicated person to supervise the lifting operation, correct unsafe behavior, and ensure the implementation of the system.

continuous improvement

Regularly analyze accident cases, optimize operational processes and equipment configuration, and enhance safety management level.
