When it comes to electric hoists, they are truly a "capable assistant" in industrial production and warehousing logistics.However, choosing the right electric hoist is no easy task. A good choice can ensure both safety and efficiency in the operation, while a bad one not only delays the work but may also pose potential safety hazards.Today, I'll draw on my years of experience to talk to you all about how to choose an electric hoist, from the model to the tonnage. Let's explain it step by step.
When choosing an electric hoist, the first step is to clearly understand your actual needs. Otherwise, even the most powerful equipment may not be easy to use.
The lifting capacity must be accurately calculated: This is the top priority.
You have to think about how much the heaviest thing can be lifted each time?
Don't just count the material itself. The weight of the packaging and the weight of tools like hooks should also be taken into account.
I've seen someone before, for the sake of convenience, only calculated the weight of the materials. As a result, when it came to using them, they found that the load had exceeded the limit. Fortunately, no major problems occurred.
Here's a little tip: when choosing, the rated load should be at least 30% more than the actual maximum weight.
For instance, if the maximum load to be lifted is 2 tons, the rated load of the electric hoist should be at least 2.6 tons. Only in this way can one feel at ease.
Don't be careless when raising the height: You need to measure the vertical distance from the lifting point to where the item is to be placed.
Nowadays, the common lifting heights include 6 meters, 9 meters, and 12 meters. If that's not enough, some manufacturers can also customize them.
I remember once in a workshop, because I didn't calculate the lifting height accurately, the hoist I bought got stuck halfway through the lifting process. In the end, I had to struggle to replace it with a new one, which was really a waste of time.
So when measuring, be sure to be careful and don't find it troublesome.
There are many models of electric hoists. You should choose according to your own situation. It's not the case that the more expensive and larger ones are necessarily better.
Look at the structural types: There are mainly two types, namely steel wire rope and chain link.
Generally speaking, for those weighing less than 5 tons, chain hoists are quite suitable. They are small in size and light in weight, making them just right for scenarios that don't take up much space.
However, if the lifting capacity exceeds 5 tons or it is necessary to move left and right on I-shaped steel rails, then wire rope electric hoists are more reliable. They usually come with electric trolleys, making them much more convenient to move.
I used to work in a heavy machinery factory. They all used steel wire ropes because they often had to lift large-tonnage parts and moved them frequently.
Special working conditions require special treatment: If it is used in places with flammable and explosive gases, explosion-proof electric hoists are essential. Safety comes first, after all.
In damp places like port docks, stainless steel is less likely to rust.
If the temperature in a smelting plant is high, it is necessary to choose one specifically designed for metallurgy.
There are also some places with particularly limited space where micro electric hoists come in handy.
If the floor height of the factory building is low, a low-clearance electric hoist can save a lot of space.
There are certain requirements for the lifting speed: In some places, the lifting speed is not so demanding, and a single-speed one is sufficient.
But when it comes to fine work, such as assembling precision parts, a dual-speed one is much more useful. When it's slow, it can precisely position.
I used to work in an auto parts factory. When they were installing engines, they deliberately used two-speed ones. By adjusting the slow gear, the parts could be connected quickly and accurately.
The tonnage of electric hoists ranges from several hundred kilograms to tens of tons. When choosing, one must not be ambiguous.
Remember one principle: "It's better to be big than small."
If the tonnage is chosen too small and overloading occurs frequently, not only will the equipment break down quickly, but if something falls in, the consequences would be unimaginable.
For instance, usually lifting items weighing around 1.5 tons, and occasionally up to 1.8 tons, it would be safer to choose a 2-ton one. Don't save that little money; safety is more important than anything else.
I've seen people choose small-tonnage ones to save money. As a result, the gourds broke down in just a few months and an accident almost occurred. It was not worth it.
Apart from the model and tonnage, there are also some details that cannot be ignored.
Power and voltage: Some electric hoists use batteries, which are convenient for moving and can be recharged when the power runs out. However, the battery life needs to be well considered. Don't run out of power while you are working.
Those plugged in can be used all the time, but they need a stable power supply.
There's also the voltage. The common types of industrial electricity used in our country are three-phase 380V and single-phase 220V. Before purchasing, make sure to check carefully to avoid buying something with an incorrect voltage that won't work.
I once encountered a customer who bought the wrong voltage. It was extremely troublesome to keep changing it back and forth.
The control method is convenient: Manual control is simple and direct, but sometimes it is not convenient to operate.
It's much more comfortable with a remote control. You can operate it from a distance, especially in some dangerous places, which can ensure personal safety.
If you want to connect with the production line for automated operation, you have to choose one that can be automatically controlled.
Safety performance is the bottom line: overload protection must be available, and power should be automatically cut off when overloaded.
Limit protection is also indispensable to prevent the hook from hitting the top or falling to the bottom.
The emergency stop button is even more life-saving in critical moments. It must work properly.
When purchasing, you must carefully check whether all these functions are working well.
If you are struggling to choose an electric hoist and are unsure about the tonnage or model that is the most suitable, don't hesitate. Just contact our technicians at any time.
Whether you are engaged in production in the workshop, managing logistics in the warehouse, or even working in some special environments such as high-temperature workshops or damp docks, our technicians can help you analyze your needs bit by bit based on your specific usage scenarios, recommend the most reliable selection plan for you, and ensure that it is both convenient and reassuring for you to use.
Speaking of this, I also need to mention our catet company to you.
As an established brand that has been in the lifting equipment field for many years, we have always prioritized product quality and user needs.
From raw material procurement to production and processing, every link is strictly controlled to ensure that every electric hoist leaving the factory can stand the test.
Over the years, we have also accumulated a lot of experience in customizing solutions for customers in different industries. Whether it is fine operations with small tonnage or heavy lifting with large tonnage, we can always come up with satisfactory solutions
