Electric Chain Hoist – Common Problems and Risks

Electric chain hoists offer a number of benefits including increased efficiency, precise control and lower maintenance demands. They are a popular option in construction and manufacturing applications.

To ensure your electric hoist works properly, you must understand its power requirements. You must also know if your job site is wired for 230 volts or less.

Safety Features

Hoists are a must-have for any workplace that deals with heavy lifting on a regular basis. They reduce manual effort, boost workflow efficiency, and save businesses considerable money. But despite these significant operational advantages, electric chain hoists aren’t without their own set of safety risks and issues.

The most important aspect of any hoist is its ability to hold your load safely in place. Whether it is a load that is too heavy or one that moves unexpectedly, if the hoist fails to do so, you could end up with major property damage or even serious injury.

To mitigate this risk, most electric chain hoists come with a variety of safety features to protect workers. For instance, they use a friction clutch to prevent overloading and a thermal protector to ensure that the motor doesn’t overheat. In addition, some models feature a electric chain hoist helical gearbox that allows for extended usage without any wear and tear.

The other safety feature is a limit switch that stops the motor when either the upper or lower limit is reached. This prevents the hoist from over-traveling and causing damage to the load or the hoist body. It’s also crucial to note that you should never be underneath a hoisted load, and the area surrounding it should be clear of personnel. Additionally, you should only operate your hoist for short periods of time, as frequent use can accelerate its wear and tear.

Weight Capacity

Unlike manual hoists, electric chain hoists use motors to move loads and do not depend on operator strength. This means that these devices can be much more efficient, saving you money in the long run. They also require less up-front investment than air and hand-operated models, making them a great choice for businesses looking to save on upfront costs.

Before purchasing an electric chain hoist, make sure to consider its weight capacity and power requirements. This includes the motor’s working load limit (WLL) and duty cycle. The WLL is the maximum amount of weight that the hoist can lift, while the duty cycle indicates how many times it can be used per hour before requiring a cool-down period.

Another factor to consider is the type of load that you’re going to be lifting. Some hoists are designed for heavy industrial use, while others are best suited for lighter work. If you’re going to be using the hoist for heavy loads, choose a model with a higher duty cycle and higher WLL to ensure safety.

An electric chain hoist should be mounted electric chain hoist in a safe location and attached to the load with a suitable sling or shackle. It should be attached in a way that ensures it cannot come into contact with any other objects or people in the area around it.

Maintenance

An electric chain hoist is a versatile and valuable piece of equipment in any workplace. However, it does require some regular maintenance in order to keep working safely and efficiently. This is particularly true if it is used for heavy lifting tasks, as these may place additional stress on the components of the hoist.

The two main parts of an electric chain hoist are the brake and reducer. Both of these are prone to problems, but it is possible to prevent these issues by following the proper maintenance procedures. For example, lubricating the equipment can help to reduce friction and prolong its lifespan.

In addition, it is important to limit the duration of each operation to the maximum capacity indicated on the identification plate and to use a hoist with the correct voltage and frequency. Using the hoist for longer than this may accelerate its wear and shorten its life.

Another important aspect of hoist maintenance is cleaning it regularly. This is important to prevent buildup of rust or debris, which can cause damage and impact performance. Using the right chemicals and tools can also be helpful in eliminating rust and preventing further corrosion. Additionally, the hoist should be stored away from humid areas and high temperatures in order to preserve its performance. If you are unsure about what maintenance requirements your electric chain hoist requires, it is a good idea to consult a professional.

Noise

The electric chain hoist is an amazing innovation that has brought immense advantages to a variety of industries and applications. However, these machines can be subject to occasional technical problems that need to be repaired or addressed as soon as possible. If not handled promptly, these issues can lead to a loss of productivity or safety.

One of the main reasons for noise produced by an electric chain hoist is a result of a faulty braking system. The braking mechanism is responsible for stopping the lift when it encounters any load that exceeds its capacity. If the braking mechanism fails, the load will continue to slide and cause damage to the system. To avoid this, a standard chain electric hoist should have both mechanical and electromagnetic brake systems.

Another factor that can affect the noise of an electric chain hoist is its power requirements based on the hoist’s capacity. Some electric hoists require only 120 volts to run, while others may require up to 460 volts. Knowing the type of power your job site has available will help you narrow down your options for hoists.
