Overhead crane is among the most crucial machines in workstations/workshops and factories, because it assists in achieving mechanized production and reducing the heavy physical labor. This crane is used in many industries to lift and transport heavy materials, and it has either a single girder or a double girder type. The design of an overhead crane system is the major factor in its complexity and determining its cost. The double girder overhead crane( grúa viajera bipuente ) consists of two bridge beams and is used for heavy-duty applications.
Double Girder Overhead Crane Applications And Components
The double girder overhead crane has gained popularity over the past few decades in the lifting equipment industry. This type of overhead crane has lots of types like the electric and electromagnetic models. It’s a kind of crane that is designed to have double girders for lifting and transferring materials in the factories, workstations, garages and even in the maintenance workshops. A double girder crane can be top or under running with the top running providing the greatest hook height. Bridge cranes(grúas viajeras) are configured depending on the work in your application.
Main Components of Double Girder Crane
- The girder frame. This consist of parts like the main girder, trolley traveling track, and the cab.
- Lifting trolley. This device is equipped with both lifting and traveling mechanisms.
- Electric control system.
- Crane operating device.

Factors to Consider When Choosing The Right Crane to Buy
- Background of the supplier- Check their records and reviews from their previous clients to understand their credibility.
- The company’s certification and manufacturing practices- Ensure it’s ISO certified
- The weight lifting capacity of the crane
- Size, that is, both height and base area
- The movement mechanism of that crane
When It Comes to Installation, Consider Things Like:
- Safety
- Durability
- Cost/investment
- Maintainance
- Operation cycle.
Additionally, ensure that you do routine inspections( inspecciones de rutina ) to ensure the safety of the operators. Some of the things you can do is testing the crane movement.
