A monorail hoist is a lifting device used to move materials or products within a limited area. It consists of a steel beam, a metal cart or trolley, a hoist, and a drive mechanism. Monorail hoists can be customized to meet the needs of any product line, but they require frequent stopping and restarting, which can slow down production.
A monorail hoist is a lifting device that serves as an alternative to traditional cranes or conveyor belts. Manufacturers often use these hoists to move materials or products within a limited area, rather than an entire building. They can be incorporated into the structure of a building, where they become part of the ceiling or columns, or added later using separate supports. A monorail hoist makes it easy to lift products onto racks for storage or transport them from one part of a room to another for further assembly and production.
While the exact design of the monorail hoist will vary by application, each unit shares some basic characteristics in common. A steel beam runs parallel to the floor and supports a metal cart or trolley. This trolley can slide over or under the beam depending on the ceiling height and required lifting capacity. A steel cable or chain supports a hoist attached to the trolley. As this trolley runs the length of the beam, it carries the hoist and an attached load to the desired location.
Some monorail dumbwaiters simply run in a straight line from one end of a room to the other. Others feature a complex design that includes bends, elevation changes, and hoist-to-hoist transfers. These complex monorail hoist designs typically serve as an alternative to traditional conveyor belts and act as a type of assembly line for large or oversized products. As the monorail hoist transfers product along the line, workers can complete various steps within the manufacturing process.
A monorail hoist can have different types of drive mechanisms. Many are electric and rely on an electric motor. Hoists used for very heavy loads often require a pneumatic or hydraulic drive system. Some very simple models may also rely on manual operation, in which workers attach an object to the hoist and then roll the trolley from one end of the monorail by hand to the other.
One of the main advantages of the monorail hoist is its flexibility. Buyers can customize these units to meet the needs of any type of product line. They are also suitable for small spaces, where a forklift or crane would be too bulky or impractical. Unlike a conveyor belt or other assembly line system, a monorail hoist also leaves the floor area unobstructed.
The biggest disadvantage of this type of system is that it requires frequent stopping and restarting. Instead of a continuous production process, workers are forced to produce one unit at a time before relocating the hoist. This can slow down production and reduce efficiency.
