Double Girder Overhead Crane

Double Girder Overhead Crane

When you want an option in a crane that will allow you to lift and transport medium to really heavy loads, you need to look at a double girder overhead crane. These types of cranes are designed to offer immense load bearing and carrying capacity, but with a minimal amount of deadweight. The design of these cranes is such that their structure is extremely precise and it allows travelling in such a manner that the wear and tear on the end carriages as well as the runway is minimal. In addition to all this, the load hook is designed in such a manner that it can be raised between the two girders of the crane. This allows the crane to lift the maximum amount of weight.

Normally, there are two beams, which are positioned adjacent to each other and it is this positioning that offers the finest support to the material that is being moved. This is also why larger and heavier equipment and products can be moved with such ease.

Here are some of the benefits of using a double girder overhead crane:

  • The design is such that it offers a high level of torsional rigidity
  • The travelling part happens very smoothly and efficiently
  • Because the drives are extremely low maintenance, the wear and tear is also normally very low
  • In most case, the connections between the girders and the end trucks is manufactured to be extremely precise and also ensures minimum wear and tear
  • Because the deadweight is normally quite low, the overall costs are generally quite low
  • In most double girder overhead cranes, there is a rope hoist, which also helps reduce the operational cost
  • Most cranes have a design wherein the control pendent is suspended, which allows for dethatched travel on the actual girder itself
  • The power supply is normally via a trolley that is protected via a ground conductor, ensuring minimal chances of electrical mishaps

The double girder overhead crane is an extremely versatile piece of equipment, and most good companies will customise the same to match individualistic requirements. Here are just some of the

customisations that can be offered with this kind of crane:

  • Controlled by a pendent switch
  • Controlled via radio control
  • Rope relays which offer protection to the hoist from any damage during loading or unloading
  • End carriages which support any specific requirements related to runways
  • Anti-collision protection methods
  • Distance controls on cranes
  • Full length walkways, maintenance platforms, floodlights as well as cabs
