As cranes slowly expand the market, the models of cranes are also seen in accordance with people's needs. The more models of cranes, the more people buy the lifting machine is also a very confused thing, first of all, the following content I will give you a detailed introduction to the five tutorials for the purchase of the electric hoist cranes.
Choose the electric hoist crane, look at the brand, look at the quality, the following questions about the quality of the lifting machine, I introduce a few points:
1. Look at the certificate. When choosing an indoor and outdoor lifter, first look at the appearance. Under normal circumstances, the lifting machine produced by the small factory has a rough appearance, the surface is mostly sprayed, and the outer packaging is simple, the manual, the pass certificate is incomplete, and there is no verification and other problems. The lifting machines produced by China coal group have various certificates, fine workmanship and beautiful appearance.
2. View the pulleys. The pulleys produced by regular manufacturers are large in size and excellent in quality, and can reach the rated lifting load very well. The pulleys produced by small manufacturers are thin and small, and the quality cannot be guaranteed. There is a great hidden danger in the use process.
3. Listen to the sound. Plug in the power supply and run the motor to listen to the sound of the motor. The motor of the lifting machine produced by professional manufacturers has low noise during operation, and the main engine is stable as a rock.
4. View the bracket. The choice of bracket is important, and the brackets that fail in quality are easily deformed or bent during use. The lifting machine bracket produced by regular manufacturers, the steel pipe is thick and heavy, and the main pole adopts seamless steel pipe with thickness of more than 5mm, so it is thick and safe, and the steel pipe produced by small manufacturers is thin and light, and the thickness of the pipe wall is not up to standard, and Quality is not guaranteed.
5. View the host. The mainframe chassis manufactured by the regular manufacturer is relatively large, the base is thick and equipped with a reversing device, and the small crane manufactured by a small manufacturer has no safety measures for the machine to cut corners. The base is also not reinforced, and it is easy to use during use. There is a side down, so be sure to check the host carefully when selecting.
