One of our customer needed to install a crane with a lifting weight of 600KG, voltage of 380V and wire rope of Φ8mm in a workshop with relatively small space. So we had to take the the following countermeasures to solve some problems:
Custom 380V Electric Hoist
- Test the winding method of the copper wire to make sure it is qualified for the voltage of 380V.
- Test the power and assemble the motor after testing the copper wire.
- The diameter of standard steel wire rope is 4mm, so the drum should be customized again. The drum sheet and pipe were produced in stamping workshop to enlarge the holes of the steel wire rope on the drum sheet and pipe. Then, choose the appropriate welding parameters and reasonable welding sequence to carry out the welding process. The surface of the drum should be rolled and shot-blasted to improve the surface strength of the components.
- Assemble the product and test it to ensure that the product works normally under the voltage of 380V, lifting weight of 600KG with the 8mm wire rope for 12 hours.
In June 2016, the customer received the products, which fully satisfied their needs. Within a month, they placed a second order.
