Electric chain hoist is one kind of light and small lifting equipment. It mainly consists of electric motor, transmission mechanism and sprocket. It can be used individually, and can also be installed on I-beam steel, curve track, jib crane, overhead crane and gantry crane. Chain hoist makes it convenient to lift weight, load and unload goods and maintain equipment.
If you are considering the possibility of investing in an electric chain hoist, then you are making a smart move. In general, there are many advantages to owning an electric chain hoist, and you will soon be able to take advantage of these benefits once you own one. With this in mind, let‘s explore some of the key advantages offered by an electric chain hoist.
First of all, it is a good idea to fully understand what you are purchasing and what its intended purpose is.
An electric chain hoist is simply a device that is designed to lift and lower heavy loads. Primarily, this will be performed using a wire or a rope that is looped around the drum or wheel. Next, the machine will generally be perched overhead using a hook, trolley, or a log.
The hoist or trolley will usually be controlled by electricity ?although there are air and hand models available. But as you expect, an electric chain hoist gives you far better control, power, and versatility.
AIMIX Group, a famous electric hoist supplier, designs and produces lifting hoists according to international standards. Our hoists are very popular with many advantages, such as advanced properties, beautiful appearance, small volume, reliable performance, wide application. All inner gears are through high temperature quenching, which increases the tenacity and wear ability.
Every good hoist part can maximize the overall function of chain hoist. And it is very useful to learn the functions of hoist parts, because it can help users to know how to prolong the service life of product and how to choose high quality item with reasonable price. The followings are important parts of electrical hoist.
First is double brake system
It includes magnetic brake system and mechanical brake, two complete and individual systems. This type of brake system can reduce brake failure rate and increase safety, also benefit to dissipate heat. Magnetic brake has fast response and provides forward brake force. It adopts non-asbestos brake lining, which greatly extends the maintenance cycle. The brake system has been tested for thousands of times. Mechanical brake system mutually coordinates with magnetic brake system, and can stop the item working in anytime.
Second is limit switch
When electric chain hoists up and down to limit position, limit switch can automatically cut off the power, so that avoid collision between lifting material and hoist body.
Third is variable-speed gear
Electric chain hoist adopts reliable helical gear, because it can prolong the service life through reducing the influence and vibration of gear bite in maximum degree. This special design makes the gear more durable. The gear is made of excellent alloy steel and through professional fine heat-treatment.
Fourth is button control handle
Our company produces button control handle with light weight, anti-rain, fast response. Standard voltage of chain electric hoist handle is 24V-36V. Low voltage can effectively protect the operator from electric damage.
Fifth is reverse phase protector
It can protect chain hoist or motor from damage caused by wrong cable connection or reverse connection.
Fifth is chain
Our group adopts chains made of low carbon alloy steel. This kind of chain is more durable and safe. The length of chain can be customized according to customers’ needs. Every chain is equipped with a bag for clear and tidy appearance. With rust-proof oil in the bag, the chain is not easy to rust and can prolong the service life of electrical hoists.
Sixth is load pulley
Load pulley is made of alloy steel, anti-abrasion. It is through professional heat-treatment and can match with chains well.
Seventh is emergency switch
It is a red button on the top of handle, used to stop the electrical hoist in emergency. Pushing the button, the power of lifting chain hoist is cut off. And the button has auto lock function.
Eighth is overload protection
Our company adds overload protection device for extra safety. This is special security device for operator, chain electric hoist and load. When the load is over rated value, overload protection device automatically works and electric hoist stops lifting.
There is a certain trick that many people use when it comes to electric chain hoists, and it is a process known as double reeving.
Simply put, this technique involves using an additional bottom block which you can attach to the unit, and it allows you to double the lifting power of your hoist. In fact, it is usually possible to turn a one-ton hoist into a two-ton hoist using this process.
1. Install chain box.
2. Connect electric cable. When connecting cable, the power must be cut off. At the same time, the ground line should be earth grounding well. Otherwise, operator will feel electric shock when he touches the chain electric hoist or chain.
3. Lubricate the loading chains. Lubrication degree of chains is an important factor that influence the chain’s service life. Lubricate the loading chains timely and effectively, because this can ensures the long service life.
4. Check chains’ arrangement.
5. Check working voltage.
1. Regularly check the rail, hook in visual, check brake device, balance pulley in hand control.
2. Regularly add butter to gear to keep lubricated.
3. Check whether the chain is aging, damage, the switch is sensitive, insulating sleeve is loose.
4. After working for 500 hours, please check whether the lubrication is enough. Check lubrication condition at least once every three month.
5. Using chain hoist outdoor, anti-rain device is necessary.
6. Keep chains dry, add engine oil to chain for lubrication. Please add engine oil in high dust factory. Regularly clear chains and grooves to keep chains running smoothly.
7. If not using chain hoist for long, please do anti-rust treatment and clear maintenance, and run up and down for 1-3 minutes to maintain performance.
There are many advantages to owning an electric chain hoist, and one of the main ones is its ability to lift very heavy loads. However, when you are shopping around to purchase one of these machines, you need to know how much weight you intend to lift, because buying one that underpowered will certainly be a regret.
Additionally, electric chain hoists can move at a surprisingly brisk pace, but knowing the speed of lifts your chosen machine is capable of will be an important subject to consider before you buy.
There is no denying that the cost of an electric chain hoist can vary greatly depending on the size, quality, and manufacturer. In most cases, it is best to begin with the end in mind, so you should think about the main task you will be using the chain hoist for.
Additionally, you want to ensure the manufacturer uses a quality clutch hub, because this is a key part of the lifting mechanism, and it will help you avoid the dangerous condition of overloading.
Overall, is clear to see that investing in an electric chain hoist is a fantastic decision for anybody who has a great deal of heavy and repetitive lifting to perform.
This guide has shown you several of the key advantages offered by an electric chain hoist, such as double revving. And you have also learned several key considerations to think about whenever you are planning to purchase an electric chain hoist.
Now that you have read this guide, you should understand why you have making a great investment.
