Improved safety standards
Safety plays a significant role in industrial applications and electric chain hoists are excellent. It boasts advanced safety features, which include emergency stop mechanisms and overload protection. However, these safety features reduce the risk of injuries and accidents.
Power up
It all starts with the electric motor – the powerhouse behind the hoist. When you hit the button to lift a load, this motor springs into action, gobbling up electrical energy and transforming it into mechanical power. This transformation sets the stage for the lifting magic to unfold.
Shifting gears
Next up, we have the gearbox. Think of it as the translator between the motor's high-speed energy and the hoist's need for strength. The gearbox takes speedy energy and morphs it into slower but super-strong power, perfect for hoisting heavy stuff.
Chain in motion
Now comes the exciting part – the chain starts moving! Wrapped around a sprocket, it connected to the gearbox's output shaft. As the sprocket spins, it tugs on the chain, hoisting the hook (and whatever it is carrying) up into the air. And the best part? You are in control, thanks to the handy control pendant that lets you adjust the speed and height of the lift with ease.
Once your load reaches its destination, the brake system locks it in place securely, ready for dismount.

Electrical chain hoists may seem like ordinary machines, but they are the leads of heavy lifting. With their blend of mechanical prowess and electrical wizardry, they make moving mountains look like a walk in the park. So, the next time you see one in action, take a moment to appreciate the magic happening behind the scenes.
What Are Components And Main Functions Of 2 Ton Electric Chain Hoist?
Lifting chain
The lifting chain of an electric chain hoist adopts φ 7.1mm and φ 11.2mm 80 grade surface carbon black treated lifting chain to ensure its safety and durability. The strong hardening surface of the lifting chain can prevent the damage of products and the softening of core materials to maintain the high performance of the lifting chain for a long time.
The chain of the electric chain hoist is made of low-carbon alloy steel, which makes the chain more ductile, stronger and wear-resistant, and ensures safety in work. The length of the lifting chain can be lengthened and customized according to the requirements of customers, and can also be used in the case of large travel. The chain of the chain electric hoist is equipped with a chain bag, which makes the chain electric hoist look clean, neat and beautiful. The chain bag is also filled with antirust oil, so that the chain is not easy to rust to prolong the service life of the electric hoist.
Dual brake system
Two complete and independent brake systems not only reduce the possibility of brake failure but also enhance the safety of the brake and facilitate heat dissipation.
● The electromagnetic braking system responds quickly and provides a positive braking force. The use of non-asbestos brake lining greatly prolongs the maintenance cycle. The brake system has been tested more than 22500 times.
● The mechanical brake is very reliable. The mechanical brake and electromagnetic brake coordinate with each other and can stop the machine at any time.
Speed change gear
The standard chain electric hoist generally adopts spiral gear to provide reliability and can prolong its service life by minimizing the impact of gear bite and vibration. The special design of the gear enhances the durability of the gear, and the gear is made of alloy steel, which obtains the maximum strength and wears resistance after professional fine heat treatment.
Reverse phase protector
The reverse protector can protect against the damage to the hoist or hoist motor caused by the wrong connection (reverse connection) of the power line.
Limit switch
When the chain electric hoist rises or falls to the limit, the limit switch will automatically cut off the power, and the limit switch can effectively prevent the collision between the lifting weight and the machine body.
Emergency stop switch
This button is used to stop the action of the hoist in case of an emergency. It is a red button in the shape of the mushroom head, which is located at the top of the pressing handle. When the button is pressed, the power supply of the hoist will be cut off, and the button has the function of automatic locking.
Button control handle
The light and heavyweight button control has rainproof function and sensitive response. The operating handle voltage of the standard ring chain hoist is 24v-36v. Low voltage control can effectively protect the operator from electric shock. The voltage of the operating handle is controlled at 24v-36v, which is also a mandatory requirement of the aqsiq for special lifting equipment.
Anti-wear load pulley
The load pulley is made of alloy steel and has undergone professional heat treatment for the purpose of anti-wear and smooth matching with the chain. The new chain design guides the smooth insertion of the chain into the pulley.
Overload protection
Hoist and load is a special protection device. When the load is greater than the set value, the overload protection will be enabled automatically and the hoist lifting will stop automatically.
How to Choose 2 Ton Electric Chain Hoist
The weight of the load
This is the first and most important factor that you need to consider when choosing electric chain hoists. The load that you'll be lifting will determine the type of hoist that you need to buy. As a general rule of thumb, for less than ten tons of lifting capacity, a chain hoist is preferred. However, for lifting greater weights, an electrical wire hoist is suitable. But this doesn't hold with high lifting height. So, depending on your industry needs and requirements, the choice of hoists will vary.
Application requirement
After determining the load type, you must select the application for which the hoist will be used. Is it something you're planning to employ for product assembly? If this is the case, high precision will be required. It's also crucial to know if you're employing any devices below the hook. What are your duty cycles, for example?
Lifting speed
The lifting speed must be precisely adjusted for proper loading and unloading of the materials being lifted.
The work environment
The environment in which your hoist will be operated is perhaps more significant than the lift speed. Factory conditions may be harsh on gear, so it's critical to understand how the workplace will affect your equipment. 4.Gearbox leaking and subsequent hoist faults may occur if the hoist is used in extremely high-temperature situations, for example. Shallow temperatures, likewise, can cause cracks to form or internal components to freeze. The operation of your hoist can also be harmed if you place it in an environment with excessive temperature swings. Electrical short circuits and associated equipment malfunction can occur as a result of frequent temperature changes.
The duty cycle
This refers to the length of time your hoist will be in operation. The amount of hours that the hoist will run at a time can have an impact on its longevity. Because electrical hoists must disperse heat from their motors, the duty cycle must be long. This means they'll need plenty of time to cool off and recover. Otherwise, you may be courting equipment breakdowns.
The height of the lift
The height to which you need to lift the load is also a consideration when selecting a hoist. Electric chain hoists usually have a container where the extra chain is spooled. The longer the chain, the greater the height, and hence the larger the chain container. A too-large container, if not designed appropriately, could become a barrier to the weight being hoisted. For higher lifting heights, such as windmill hoists for turbine maintenance, an electric chain hoist is preferred.
The power source
The type of hoist you need will also dictate the type of power supply you'll need. A single phase hoist is sufficient for low duty cycle applications. If you require exceptionally high duty cycles, however, a three-phase hoist is the best option. This will ensure that you have enough power to operate the machine.
Warranty
An electrical hoist is one of the machines that goes through normal wear and tear. As a result, if you want to prevent costly repairs, you should get a device with appealing warranty benefits. Check to see if the hoist's warranty covers all necessary parts and labor. Labor is usually more expensive than parts, so it's better if your warranty covers both.
Safety features
An electric hoist is, at the end of the day, a machine. Accidents can happen in any scenario where electrical equipment is employed. As a result, check sure the hoist has all necessary safety measures, such as load limiters, before purchasing it. Self-adjusting brakes and thermal overload protection are also necessary.
Preparation before starting
The operator must be trained by the workshop safety officer and approved to operate after passing the examination;
The electric chain hoist should be checked carefully before use. For example, the installation of the lifting point is firm, the hook, the anti-dropping piece, the chain link, the flashlight door, the wire rope, the wire rope chuck and other protective devices, etc. It can be used only after it has been proved in good condition.
Boot operation
Plug in the power and turn on the control power;
Test the crane before lifting heavy objects.
Operation and precautions during equipment operation
Lifting heavy objects shall not exceed the weight specified by the electric chain hoist; it is strictly forbidden to stand or walk under the heavy objects during operation;
Do not use overloading; the brake belt must not be stained with oil;
There is no safety protection measures when the equipment is lifted, and any part of the human body is strictly prohibited under the lifting objects;
The lifting chain should be suspended vertically, and its inclination should be kept within the range of the angle between the chain and the plumb line not greater than 10-15, and the double-row chain should not be turned over and twisted.
When the diameter of the worn part of the chain decreases by 10% of the original diameter, a new chain should be replaced. When the plastic elongation of the chain reaches 5% of the original length, it must be replaced. The chain is seriously rusted and cannot be used continuously.
Parking operation
After the electric chain hoist is hoisted, put the stirring motor part on the support frame, and it is strictly forbidden to stay in the hoisting state for a long time;
After parking, unplug the power plug.
How to Maintain Electric Chain Hoist
Routine inspections
● Daily checks: It is recommended to visually inspect the electric hoist before each use. Determine if there is obvious damage, loose pieces, or indications of normal use. Keep any debris off the chain and make sure it is well-lubricated.
● Monthly inspections: Once a month, make sure to check everything more thoroughly. Inspect the hoist's framework, wiring, and controls. Check for corrosion or unusual wear and make sure all nuts and bolts are snug.
Lubrication
Lubrication plays a crucial role in ensuring the smooth operation of the chain and other moving components. Lubricate the chain and gears using the product's official recommendation. Lubricating your hoist on a regular basis will decrease friction, which in turn will avoid wear and strain.
Cleanliness
It is critical that you clean your electric chain hoist regularly. If the hoist gets dusty or unclean, it could underperform. It is recommended to clean the hoist after each use using a damp towel. On occasion, you should wash the hoist with mild soap and water; nevertheless, to prevent corrosion, wait until it is totally dry before using it again.
Load chain maintenance
Proper maintenance is essential for the load chain, which is an integral part of the hoist:
● Examine the chain on a regular basis to look for damage, elongation, or deformities. Get a new chain right away if there are any problems.
● As stated before, keep the chain well-lubricated to guarantee smooth performance.
● It is advisable to get a new chain that meets the manufacturer's specifications whenever an old one shows signs of excessive wear or elongation.
Electrical components
Electric chain hoists can't function unless certain electrical components are in pristine condition. It is a good idea to periodically inspect the switches, connectors, and cables for any indications of damage or wear. Tightening all connections and replacing broken parts right away is the best way to avoid electrical accidents.
Professional servicing
Regular electric hoist maintenance is required, but having a professional inspect and service it once a year is highly recommended. Hiring expert consultants can guarantee comprehensive inspections and repairs if your in-house maintenance staff isn't competent enough.
Load testing
Make that the hoist can manage loads up to its rated capacity by performing load tests on a regular basis. Do this at regular intervals and after any major repairs or maintenance to the hoist. Problems that can go undetected during routine inspections can be found with the use of load testing.
