Customers often ask us what is the most suitable crane for a factory, workshop or indoor use? The best option with the most coverage, is an overhead gantry crane. This is because they can lift heavy loads up, as well as move and lower them back down in all 3 axis (X,Y, Z axis) throughout the entire workspace. *See “the crane envelope” described below.
An overhead gantry crane is like the Queen in chess, able to move across, up and down and diagonally over the whole area. See photo below.
Crane Envelope: “What is the crane envelope, or hook coverage?”
There is something referred to in the crane trade as the “crane envelope” or “hook coverage” which is the actual area the crane can operate in without side pulling, or performing dangerous lifting and lowering practices.
If an industrial crane in a warehouse covers an area of say 10 meters wide (span) by 18 meters down shop the hook typically will cover 9 x 17 meters. This can vary with the length of end carriages chosen and hoist type. Chain hoists being narrower than wire rope hoists.
another recent example of a clients factory workspace was 20 metres by 12 metres. The actual area the crane could work in was 19 metres by 11.4 for example.
Here you can see some images taken from the detailed drawings we submit to the customer prior to installation.
The 2 diagrams above illustrate that although you can safely lift and move heavy items throughout virtually all of your factory/yard/warehouse/loading bay etc, the very outer edges are not reachable.
Also very popular are “Swing Jib” cranes however they are fixed in one position, typically in a loading area. Similar to a lamppost with an arm that swings through an arc of generally 240 – 290 degrees. They can only lift and move things within that arc so are a little limited. See photo below.
Jib cranes are are also known as pillar jib cranes, swing jibs, floor mounted jibs, swinging arm cranes or even boom cranes. Very occasionally client request a power slewing arm, or 360 degrees slew but the cost of these can be prohibitive.
For more information on jib cranes for sale, see here.
Wheeled A Frame Gantries or Monorail cranes.
A frames gantry cranes are used inside factories but cannot be moved under load, and are limited to one axis, as are monorail or goalpost cranes.
People Also Ask; How do I choose a crane for my factory?
Choosing a crane is an important decision and here at AG Cranes we have many years of real-world experience helping our clients get the best crane to meet their needs.
Even second-hand cranes can be a major expense for your business, so it is important that you choose something that is ideally suited for the work you need it to do.
You need to be sure that you operate a safe working environment, with only trained staff operating the crane.
What is the maximum working weight you’ll need it to lift? Safety is the always the first concern when it comes to this.
However, there is no point going way over the top buying a crane capable of lifting 30 tonnes if it is never going to lift more than 3 for instance.
What will the crane be lifting?
There are many things to consider based on this. Is the load liquid filled barrels or solid items?
The height of the potential lift is as important as the max weight.
After max load, type of load, and height, comes the size of the area of your factory /workshop.
After assessing all the requirements, what’s the cost for such a crane that will meet your needs fully.
AG cranes offers a full range of brand new and second-hand options that can work with most budgets.
