Lifting operations are common in many professions, especially in the construction industry. They can be done manually or using lifting equipment. Lifting equipment includes any technique used to raise or lower loads. There is a wide range of lifting equipment used in the construction and other industries. Most often in modern activities, a lifting mechanism with an electric hoist drive is used - electric hoists .
Hoists are basic and versatile equipment used in manufacturing, warehousing, construction and many other applications that help workers in handling and moving goods. The main distinguishing advantage of electric hoists is compactness, affordability and ease of use. Electric hoists are easily suspended from existing fixed supports such as columns, beams, walls and other elements using hooks, bolts or trolleys that slide along the monorail.
Hoists are available in various types of configurations and designs, with the load usually being secured with a lifting hook. The main factors that additionally determine the type of equipment are:
Lifting medium: The lifting medium determines the type of component used for the transmission and causes vertical movement of the hoist hook. The lifting medium includes a rope or chain. Rope and chain hoists have been in use since the 1800s, and the first electric hoists have not been in use since the early 1900s. Since then, electric hoists have proven themselves well in various fields of activity.
Operation: Determines the type of power used to move the loads being lifted. The different types include manual power, electric power, or pneumatic (air) power. The most common electric hoists, which significantly increase the speed of work while ensuring a high level of their safety.
Suspension: Suspension determines the type of mounting or method used for installation. The most common types of suspension include hooks and bolts. Other suspension types can be designed to suit specific application requirements.
