Important Factors to Consider When Purchasing an Aluminum Gantry Crane

Posted on September 24, 2018 in Gantry Cranes

A gantry crane is a type of crane used to lift and lower a load from a bridge supported by legs. The main beam that straddles the workspace and load is the gantry or I-beam. This beam holds the hoist and trolley frame. Similar to an overhead crane, a gantry is typically one that is mobile and can be moved on a series of wheels or rails.

Gantry cranes are extremely versatile but there are some variables you need to consider when purchasing one. The type of gantry you purchase depends upon what the application will be. When you are looking to purchase an aluminum gantry crane, you will need to consider a few things:

  • What will you be using your crane for?
  • How heavy are the loads you will be lifting?
  • Will you be moving those loads?
  • How large is your work area?
  • Will you need multiple setups?

Function

What will you be using your gantry crane for? Will it be used on a daily basis? How heavy do you anticipate that your loads will be?

Height

One of the first considerations you have is the overall height you will need. An adjustable gantry crane affords flexibility with a range of heights. The height of the I-beam needs to be considered in accordance with the area you will be working in.

Obstructions will have an effect on your height limitations. Ceilings, sprinkler systems, support beams or any other obstruction should be carefully considered in order for the gantry to be moved or erected as needed within those constraints.

Span

The span of the crane is the total width of the unit and, again, must be considered in accordance with the space you will be in.

I-Beam Flange Width

This is the width of your I-beam. Important to consider is that the wider the I-beam, the higher the load capacity. It is also important to make sure that all your accessories are compatible with this.

Mobility

Portable aluminum gantries are often considered when your load needs to be moved from one area to another. Portability is more versatile but some heavier loads may require a fixed crane for loads that will remain stationary.

Load Capacity

Your crane’s load capacity is the maximum weight that the crane will be able to move safely.

Material

Two options are available when it comes to gantries: aluminum and steel. Aluminum cranes are lighter and have lower weight capacities. They are more versatile, portable, and cost-efficient. Steel gantries are heavier, typically have higher weight capacities, and will be more expensive. Each crane will have different specifications so it’s important that these be checked out for each model considered. If your crane will be coming into contact with corrosive materials, aluminum has a higher resistance than steel.

Ease of Use

Depending on your needs, you will want to consider how easy your crane will be to use. Will you want to move it around or assemble and disassemble it in order to store it?
