An Introduction to Electric Hoists

electric hoist

Electric hoists are used to move heavy objects. There are several types and sizes of hoists available in the market. In this article, we’ll look at their basic construction, types, and functions. We’ll also talk about safety devices. Having an understanding of electric hoists will help you choose the right one for your application.

Basic construction

Electric hoists are flexible lifting devices with a wide variety of uses. They can be stationary or mobile, and can be attached to conveyors or trolley systems. Some are designed for particular purposes, such as operating dam gates or lifting automobile engines. Others are designed for a wide range of applications.

Electric hoists are available with various types of suspension mechanisms, including push-type and geared. Push-type hoists can be manually dragged or pulled along a beam. The disadvantage of this type of hoist is the low positioning accuracy and the high effort required for operation. Geared trolleys use hand-chains to move the hoist across the beam.

An electric hoist has several basic components, including a gearbox, a braking system, a lifting medium (wire rope or metal chain), and a metal casing. A harness attaches to the hoist hook to ensure the load is balanced. Depending on its power source, an electric hoist can use electricity from a battery, electric cables, or an electrical system.

Electric hoists need to be stable and have a wide range of speeds. This is because they need to lift the hook at controlled speeds regardless of the load. Generally, an electric hoist is powered by an induction motor. This type of motor also has an electromagnetic brake, which plays a critical role when raising and lowering the load.


Electric hoist is a type of electric powered lifting equipment. It is mainly used for lifting and drafting heavy objects. Its features include ease of operation, safety, and efficiency. Its compact design and efficient configuration ensure a smooth working process and low maintenance cost. Electric hoists are available in various models, and they can be used in different industries and environments. For example, electric hoists can be used in construction companies, factories, bridge construction, mining, and automobile manufacturing.

There are two basic types of electric hoists. There are single-phase models and dual-phase models. Single-speed hoists are suitable for limited budgets. Those with single-phase operation are the cheapest types. They also offer lower lifting speeds. The lifting speed is usually measured in meters per minute.

Electric wire rope hoists use wire rope instead of steel chains. Consequently, they are more flexible and mobile. They are used in small factories and can handle light loads. Typically, their capacities vary from an eighth of a ton to five tons. They are not the best choice for large scale industrial facilities. However, they can be easy to use and require little maintenance.

Electric chain hoists have a small footprint, but are extremely powerful. This type of electric hoist is suitable for lifting various kinds of materials. They are easy to operate and can be used for lifting goods and equipment. They can be installed on an I beam, curved track, or a jib crane rail.


An electric hoist is a device used for lifting loads using electricity. It has several features. This equipment has a low weight and a high efficiency. It is available in various types. It has various functions, including lifting weight, lifting speed, and lifting torque. It also has safety features such as a dc electromagnetic brake.

An electric hoist has a control panel where you can set different parameters, such as speed and direction. It also has safety devices, such as sensors, to prevent the load from falling. The controller (1) sends signals to the electric panel (2), which supplies power to the motor (4). The brake releases when a signal from the controller is received.

Another feature of an electric hoist is its flexibility. These machines can be used in a wide range of environments. They can move left or right through a set of end trucks, or back and forth over a fixed bridge. You can also control the lifting and positioning parameters remotely. For example, if you’re working with a large object, you can choose an electric hoist with a long bridge.

Electric hoists are common in industrial settings and are also used in large ships and docks. Their light weight, compact design, and simple operation make them ideal for a variety of different applications. This type of hoist also requires very little space and is relatively inexpensive.

Safety devices

An electric hoist can come equipped with various safety devices to prevent an accident. These devices sense the force of the load and automatically prevent lifting if the load exceeds a preset percentage. Typically, the percentage ranges from 100 to 125 percent. Other safety features include overload protective devices, micro-speed control, and Electronic Programmable Limit Switches.

Aside from these safety features, hoist operators should also know how to properly operate the hoist. For example, operators must pay special attention to the condition of the hook and chain to ensure that they do not become loose or damaged. They must also make sure that the hook is balanced, and the safety latch is engaged before lifting.

In addition to warnings and limits, operators should also be aware of the rated capacity of the electric hoist. This is the maximum weight that the hoist is capable of carrying before it starts buckling. This value depends on the motor power, the rigidity of the electric hoist assembly, and the strength of the wire rope or load chain. Hence, the maximum load that a hoist can safely carry is called the working load limit. To determine the working load limit of an electric hoist, the minimum breaking load should be multiplied by the factor of safety, the construction of the hoist, and the risk posed to the workers.

A load overload can damage a crane. This is why overload protection devices are recommended. Overload protection devices are often retrofitted onto existing cranes. They should also be used in facilities where lifting capacity has exceeded limits in the past. Remote monitoring software can further enhance overload protection capabilities. For example, Konecranes TRUCONNECT(r) Remote Monitoring can alert safety managers or other designated personnel when an overload occurs.


An electric hoist is a common piece of light lifting equipment. It is an important production tool for enterprises. However, it is inevitable that some of them will fail. Fortunately, there are several ways to minimize the cost of electric hoist maintenance. These tips will help you reduce the expenses while ensuring that your electric hoists work properly and safely.

The report also highlights strategies to overcome COVID-19 threats and the impact of regional conflicts. The report also provides dashboard overviews of the top players in the industry. This will help you determine your business strategy.

When purchasing an electric hoist, you should check the rated capacity, which is the maximum weight a hoist can carry before it buckles. This number depends on the motor capacity and rigidity of the electric hoist assembly, as well as the strength of wire rope or load chain. Also, ensure that the hook is balanced, and that the safety latch is engaged before lifting.

The Demag DC chain hoist is one of the cheapest models. Its standard features make it a great choice for jib cranes and workstation crane systems. These models are also easy to move by operators. Demag’s philosophy is based on modular systems and high quality standards. Each component of the hoist is tested continuously during manufacturing.


An electric hoist is an equipment used to lift heavy loads. They are very popular in industrial environments and help reduce costs and risks associated with manual labour. They are used in many industries and are often found in warehouses, service ports, and construction sites. They are also commonly used in film studios to move heavy cameras and other large objects.
