The difference between hydraulic lifting platform and electric hoist

The difference between hydraulic lifting platform and electric hoist

Perhaps you are not quite sure yet. In the past, when we did not use lifting platforms, we used electric hoists for work. At that time, we used this type of equipment, but now we can see that few people use this type of equipment again because the quality inspection department canceled it.

Why cancel this device (sh è b è i)? There is no other reason, firstly because the cost of this equipment is too high. The second reason is that the security of this device is really not very good. And this equipment is only suitable for some small workshops, because for these small workshops, they do not have the ability to install lifting platforms, so they can only use this equipment for transporting goods up and down. But the safety of this electric hoist is really worrying because it does not have protective devices. Therefore, if there is a problem during transportation, there will be no remedial measures (referring to the solution to the problem). For such a device, many people should be aware of its danger.

Compared to the same lifting platform and electric hoist, the safety of the lifting platform will be greatly improved. Not only will there be a series of complete safety equipment, but it will also be equipped with both electric and manual driving methods. This means that if there is a sudden power outage during use, we can still use manual methods to safely descend the lifting platform. This is just one aspect of the comparison between lifting platforms and electric hoists, there will be more comparisons in various aspects. No matter how we compare ourselves, we can ultimately see that using a lifting platform is safer and more convenient than an electric hoist.
