The inspection of European electric hoists usually involves multiple aspects to ensure their safety, reliability, and performance meet relevant standards and regulatory requirements. Here are some possible inspection contents:

1、 Appearance and structural inspection

Appearance inspection: visually inspect the appearance of the electric hoist to observe for any obvious damage, deformation, corrosion, paint peeling, and other issues.

Structural integrity: Check the overall structure of the electric hoist to ensure that there are no defects in the shell, hook, chain (or wire rope), motor and other components, and that the connections are securely fastened without looseness.

2、 Electrical performance testing

Electrical connection: Check whether the electrical connection of the electric hoist is correct and firm, and whether the cables and joints are damaged or loose.

Insulation resistance: Use an insulation resistance tester to measure the insulation resistance of the electric hoist motor to ensure its good electrical insulation performance.

Voltage withstand test: Conduct a voltage withstand test on the motor and electrical control system of the electric hoist using voltage withstand testing equipment to evaluate its ability to withstand voltage surges.

3、 Mechanical performance testing

Hook and chain (or wire rope):

Check if the hook rotates flexibly, if the surface is smooth, and if the threads are intact.

Check whether the chain (or wire rope) has broken strands, deformation, etc., and whether it is correctly wound in the groove of the drum rope.

Brake:

Check whether the brake is flexible and reliable, whether the brake friction surface is flat, without cracks or damage.

Conduct braking performance testing to ensure that it can quickly and stably stop running under rated load.

Walking mechanism:

Check whether the wheels, couplings, reducers and other components are intact, and whether there is any abnormal wear or damage.

Check if the track joint is reliable and ensure that the electric hoist runs smoothly on the track.

4、 Safety performance inspection

Limit switch: Check the function of the upper and lower limit switches of the electric hoist to ensure that it can automatically stop running when it reaches the set position, to prevent over rolling and toppling.

Overload protection: Simulate overload conditions, test whether the overload protection function of the electric hoist is effective, and ensure that it can stop running in a timely manner in case of overload.

Other safety devices: Check whether the electric hoist is equipped with overload protectors, anti decoupling devices, and other safety devices, and ensure that they are complete and effective.

5、 Functional testing

No load test: When the electric hoist is unloaded, connect the power supply for forward and reverse rotation test, and check whether the control button, limiter, rope guide and other devices are working properly.

Load test: Conduct a load test under rated load to test the operational performance and stability of the electric hoist, ensuring smooth operation under load without abnormal vibration and noise.

6、 Compliance inspection

Regulations and standards: Check whether the electric hoist complies with relevant European regulations and standards, such as the Machinery Directive, DIN EN 60204, DIN EN ISO 13849, etc.

Certification and Inspection: For electric hoists that require compliance with specific regulations or standards, check whether they have obtained the corresponding certification and inspection reports.
