3 Main Features of Hoists
Load Chain Options
Load chain options refer to the different types of load chains that can be used in hoists, such as calibrated or uncalibrated load chains, and those made of different materials such as steel or stainless steel. The choice of load chain can depend on factors such as the weight of the load being lifted, the working environment, and safety requirements.
Hoists typically use either a load chain or wire rope to lift and move loads. The choice between load chains and wire ropes will depend on the specific application, load weight, and other factors.
Chain Hoists
Chain hoists are a type of lifting equipment that uses chains to lift and move heavy loads. They can be manually operated or electrically powered, and they are available in different load capacities to handle various weight limits.
Wire Rope Hoists
Wire rope hoists are electric hoists that use wire ropes to lift and move heavy loads. They are known for their strength, durability, and ability to handle heavy loads. Wire rope hoists can be further classified into single-part and multipart hoists, based on the number of wire ropes used.
Power Options
Hoists can be powered by different sources for different applications, including electric motors, air pressure, hydraulic power, and manual power.
Electric Hoists
Electric hoists are devices that use electricity to lift heavy loads. They provide a safe, efficient, and cost-effective way to lift and move heavy loads, reducing the risk of injuries and increasing productivity. What’s more, they are also versatile, and can be mounted in different ways to fit various applications and settings.
Manual Hoists
Manual hoists are a type of hoist that is powered by human effort, typically by pulling or cranking a lever. They are often used in situations where no power source is available, or where a small load needs to be lifted or moved.
They are generally lightweight, portable, and easy to use, but can be limited in terms of the weight they can lift and the height they can reach.
Pneumatic Hoists (Air Hoists)
Pneumatic hoists, also known as ‘air hoists’, use compressed air to lift and move heavy loads. They are known for their reliability, durability, and ease of use.
Furthermore, they can handle heavy loads, meaning they are often used in environments where there is a risk of explosion or where flammable materials are present.
Mounting Options
In construction, hoists can be mounted in different ways depending on the specific needs of the job. The mounting option determines how the hoist will be secured and how it can move, making it important to choose the right mounting option for the job.
Hook-Mounted Crane Hoists
Hook-mounted crane hoists are one of the most common mounting options. They are designed to attach to a crane using a hook, making them easy to install and move.
Versatile and adaptable, they can be used in a variety of settings. However, they are limited by the crane’s capacity and are best suited for lighter loads.
Lug-Mounted Crane Hoists
Lug-mounted crane hoists are another common mounting option. They are secured to the crane using lugs or brackets, providing a more secure and stable connection than hook-mounted hoists.
This type of hoist can typically handle heavier loads and are more suitable for industrial applications.
Trolley-Mounted Crane Hoists
Trolley-mounted crane hoists are mounted on a trolley, which allows the hoist to move horizontally along the crane beam. This provides greater flexibility in moving heavy loads and allows for more efficient use of space in a warehouse or manufacturing facility.
Trolley-mounted hoists are typically used for heavy loads in more industrial settings.
Factors to Consider When Choosing an Electric Hoist
When choosing an electric hoist, there are several factors to consider to ensureconsider, ensuring that the hoist meets the specific requirements of the application. The following are some of the key factors to consider:
Load Capacity
The load capacity of the hoist should match the weight of the load that needs to be lifted. It is important to choose a hoist with a load capacity that exceeds the weight of the load to ensure safe and efficient operation.
Lifting Height
The lifting height of the hoist should be sufficient for the application. It is important to choose a hoist with a lifting height that exceeds the height that the load needs to be lifted to.
Lifting Speed
The lifting speed of the hoist should be appropriate for the application. It is important to choose a hoist with a lifting speed that is fast enough to be efficient, but slow enough to ensure safe and controlled lifting.
Duty Cycle
The duty cycle of the hoist should match the demands of the application. It is important to choose a hoist with a duty cycle that exceeds the expected usage to ensure durability and long life.
Environment
The environment in which the hoist will be used should be considered when choosing a hoist. If the environment is wet, dusty, or corrosive, a hoist with suitable protection should be chosen to ensure long-term durability.
Power Supply
The power supply available should be considered when choosing an electric hoist. If the power supply is limited or intermittent, a hoist with a lower power requirement should be chosen to ensure that the hoist can operate reliably. It is also important to consider the voltage and frequency of the power supply to ensure that the hoist is compatible.
