Simple Comparison Of Single Girder And Double Girder Bridge Cranes


A bridge crane is a piece of equipment that is used in industrial applications to lift light, medium, and heavy components. Bridge cranes are usually mounted on the supporting structures of buildings and industries. Overhead cranes can either be single girder or double girder depending on the number of support beams used. The girders are rigid and have been reinforced with rolled steel to make them stronger. This article will cover the advantages, types, applications, essential components, and leading manufacturers of the bridge cranes.

How Overhead Cranes Work

Motors provide the driving force that is required to hoist loads and at the same time move the girders along the end trucks. During operation, the mechanical power of the motor is transmitted to a system of gears which is coupled to wire ropes through a shaft. The compensation shaft reduces the speed of revolution of the gears depending on the required speed. The gears also help to increase the torque of the crane. The wire ropes are tied to a hook that is used to hoist loads up and down as the crane moves along the end trucks.

Main Types of Bridge Cranes are categorized into two depending on the number of girders installed in the design. 1. Single Girder Cranes(gruas monopuente) 2. Double Girder Cranes

1. Single Girder Bridge Cranes

On a single girder crane, the end trucks support only one girder beam. The trolley and hoist systems then run on the bottom section of the bridge and the components to be lifted are transported horizontally along the bridge. If the design is well maintained, a single girder crane can be a useful piece of equipment in an industry that deals with light to medium weight materials. Single girder cranes use less material compared to double girder cranes. The beams of single girder cranes cover shorter beam spans.

2. Double Girder Bridge Cranes

In a double girder overhead crane, two girder beams are supported by end tracks on their either sides. in most designs, the trolley and the hoist are mounted on the top sides of the beams. The top-mounting ensures that the cranes can hoist weighty loads without breaking or experiencing excess mechanical stress. The cranes can support a longer hook height because of their elevated mechanical strengths(fortalezas mecánicas). Double girder overhead cranes are suitable for beams that span longer lengths and for heavy-duty applications.

Advantages Of Single Girder Cranes Y Double Girder Cranes

1. Single Girder Cranes

  • They are simple in design and cost less than their double girders counterparts.
  • They are cost-effective for light to medium load applications.
  • The cranes are easy to install and maintain.
  • They are effective for buildings and factories with low headroom.
  • Single girder cranes are lighter than double girder cranes.

2. Double Girder Cranes

  • They can support longer hook heights.
  • The cranes can be used in longer spans.
  • Double girder(bipuente) cranes are efficient for hoisting heavy-duty loads.
  • The cranes can either be used for indoors and outdoors activities.
  • Double girder cranes can support walkways on their structures.

Essential Components of Single Girder Overhead cranes

  1. Motors Systems- motors provide the mechanical strength that is required to hoist loads and move cranes along girder beams. Motors also provide the turning force thas is required to move girder beams along the end trucks.
  2. Control Systems- The systems are used to monitor and guide the operations of the cranes. Control systems are critical in identifying potential failures of the crane systems before they break down.
  3. Electrical Systems- The electrical system is composed of circuits that supply motors with power and provide energy for the control systems.
  4. Mechanical Systems- They include trolleys, hooks, wire ropes, and bearings that facilitate the motions of the cranes. Mechanical systems also help the girder beams move efficiently along the end trucks.

Applications of Overhead Cranes

Cranes are used in the following areas:

  • Construction sites.
  • Industrial manufacturing(Manufacturas industriales).
  • In ports for loading or offloading cargo from a ship.
  • In warehouses for storing heavy loads.
  • In vehicle assembling industries.

Precautions While Working With Single Girder Overhead Cranes

– Only trained and qualified operators should operate the cranes.

– All the mechanical moving parts of the cranes should be lubricated to minimize friction.

– People should now work under cranes during their operations to prevent accidents.

– Cranes should only hoist loads of recommended capacities to prevent overloading.

– Periodic maintenance should be done on the cranes to ensure safe operations.

What A 1 Ton Bridge Crane Can Do For You

Bridge cranes are used in the handling of material from one point to another. These materials are heavy loads that must be lifted using the crane which travels across a horizontal path. These cranes lift up objects and lower them using a hoist. Different cranes can hoist different load weights of between one to 10 tons or more. If you need a one-ton crane, this is how it works and what it can do for you.

A one-ton bridge crane can carry light or moderate materials. These are single-beam bridge cranes. The ones that handle heavier tons are double beamed. The bridge can be adjusted as it moves across the horizontal runway. The beams on either side of the crane are attached to the walls of the industrial facility.

If you are using it for light to moderate loads, a free-standing crane can work, however, for greatest efficiency, a bridge crane is the best equipment. All three components, the hoist, trolley and bridge runway work together to move each load. The hoist and the trolley are hook-and-line systems which run across the material handling as it hoists the objects up and moves them to their destination where it drops them.

A one-ton bridge crane can make transporting materials from one end of your facility to the other fast and convenient. This saves you money on manual labor. It is cost-effect and can handle a multitude of different conditions in a facility.

When you choose to get a bridge crane, the building itself must be evaluated. This will help you determine if a one-ton crane is enough. With running bridge cranes, capacities are under 10 tons, but it is important to make sure your materials will not need to be carried in loads of over a ton. Otherwise, you will want a crane that can carry a heavier weight.
