The inspection and testing of electric hoists after installation are important steps to ensure their safe and reliable operation. The following are the inspection and testing steps summarized based on general standards and operational experience:
1、 Post installation inspection
Appearance inspection:
Check the appearance of the electric hoist for damage, deformation, or rust.
Confirm that all components are securely installed without any looseness.
Check whether the electrical connections such as power lines and control lines are correct and reliable.
Structural inspection:
Check whether the lifting chain or wire rope of the electric hoist is intact, without any broken wires, severe wear, or other phenomena.
Confirm that there are no cracks or deformations in the hook, pulley, and other components, and that they rotate flexibly.
Check if the assembly of mechanical components such as reducers and brakes meets the requirements.
Electrical system inspection:
Check whether the electrical components (such as contactors, relays, switches, etc.) are intact and whether the wiring is correct.
Test whether the power supply voltage meets the rated voltage requirements of the electric hoist.
Check if the grounding device is reliable to ensure the safety of the electrical system.
2、 Experiment
No load test:
Under no-load conditions, start the electric hoist to perform actions such as rising, falling, and stopping, and observe whether its operation is smooth and whether there are any abnormal sounds.
Check if the brake is sensitive and reliable, and can stop the operation of the electric hoist within the specified time.
Confirm whether safety protection devices such as limit switches and travel switches can operate correctly.
Load test:
According to the rated lifting capacity of the electric hoist, gradually increase the load for testing.
Observe whether the starting, running, braking and other performance of the electric hoist meet the requirements under different loads.
Pay special attention to the stability, braking performance, and temperature rise of the electrical system of the electric hoist under maximum lifting capacity.
Functional test:
Check if the remote control device (if equipped) of the electric hoist is sensitive and reliable, and can accurately control the movement of the electric hoist within an effective range.
Conduct multiple consecutive lifting and lowering tests to check the durability and stability of the electric hoist.
3、 Record and evaluate
Record the problems discovered during the inspection and testing process, and take timely measures to rectify them.
Evaluate whether the overall performance of the electric hoist meets the design requirements and usage needs.
Prepare inspection and testing reports, record the results and evaluation conclusions of the inspection and testing.
4、 Precautions
During inspection and testing, safety operating procedures should be strictly followed to ensure the safety of personnel and equipment.
Any discovered issues should be reported and addressed promptly to avoid leaving safety hazards.
Regularly maintain the electric hoist to extend its service life and ensure safety performance.
