What is an overhead monorail?
The overhead monorail is a type of overhead crane that moves along a rail that has a specific path. The word mono means one. This means that this crane is mounted on a number. The overhead crane monorail consists of a lifting part and a rail
The hoist or winch consists of the motor gearbox, drum, towing wire, chain, and hook. This crane lifts the load vertically to a certain height and moves it along the rail track. The elevator moves on the rail using its wheels. Its electric types are equipped with electric motors that convert electrical energy into mechanical energy
Characteristics of monorail ceiling lift
- This crane is produced in different tonnages and can lift up to a certain height.
- The rail can be supported by both ground columns and ceiling beams.
- Monorail crane is produced in single speed and double speed. Of course, single-speed models have a higher tonnage.
- It is light weight and does not add a lot of load to the main structure.
- Low-tonnage models have 4 wheels and high-tonnage models have 8 wheels to move the lifter along the rail.
- The rail is made of very strong steel material that is resistant to all kinds of environmental factors.
- It is equipped with brakes that are determined for greater safety.
- It is the best option for halls that have limited space.
It is possible to access all the desired points by placing the rail track in it
Types of monorail overhead cranes
Monorail overhead crane can be classified on two bases. One is based on the direction of movement and the other is based on the type of movement of the lift. Each of these two categories includes two types; The classification based on the movement path includes straight movement path and curved movement path, and the classification based on the type of lifting movement includes manual and automatic types. In the manual type, the lifting is moved by the operator by applying force; But in the automatic type, the lift is moved by the controller and electric mechanism
Application of monorail overhead crane
- The design type of the monorail overhead crane has made it very practical. The track design capability of this type of crane has made it play a very important role in production lines. Monorail has the ability to lift objects and transfer them in production lines. Usually, this crane is used to move repeated loads (such as moving parts in production lines). جرثقیل سقفی مونوریل را در خطوط تولید خودروسازی، پتروشیمی، فلزات، صنایع پلیمر، انبارها و … به وفور میتوان یافت
Monorail overhead crane components
The structure of the monorail crane is very simple and has few components, which can be divided into two parts. The first part includes the lift and trolley, and the second part includes the carrier beam. The lift is mounted on a wheel that can be manual or electric. Usually, the number of wheels for light loads is four, and eight wheels are used for heavy loads for ease of movement. The beam can be installed both on the ground columns and hanging from the ceiling of the hall
Monorail overhead crane design
What is more important and important in the design of the monorail crane is the design of the beam or rail. After the design of the beam, the calculations and selection of the appropriate lift and wheel are proposed for it. The design of the beam and actually the path of the load is very dependent on the space of the intended hall. In the production lines, to design the monorail overhead crane, the production process is checked and based on the type of load that the monorail crane is supposed to move, the type of lift is determined and its rail is designed.
