An electric hoist and trolley is a combination of two lifting components in a crane system that allows for the horizontal and vertical movement of loads. The electric hoist is powered by an electric motor and is used to lift and lower loads vertically. The trolley is attached to the hoist and is used to move the hoist and load horizontally along the length of the crane beam. The hoist and trolley can be operated using a pendant control or a remote control, allowing for greater precision and control during lifting operations. Electric hoists and trolleys are commonly used in manufacturing, construction, and logistics industries for heavy-duty lifting tasks.

Electric hoists and trolleys are available in a variety of types and configurations, including single-phase and three-phase models, with lifting capacities ranging from several hundred pounds to several tons. They are known for their reliability, durability, and ease of use and may include safety features such as overload protection and emergency stop buttons to ensure safe lifting operations. Proper selection and use of an electric hoist and trolley is crucial to ensure safe and efficient lifting operations. By understanding the functions and limitations of different types of electric hoists and trolleys, crane operators can select the appropriate hoist and trolley for their lifting needs and ensure safe lifting operations.
