A-Frame Gantry Systems
A-frame gantry cranes are a cost effective, easy to erect, load bearing framework. They are used for lifting applications in singular or multiple locations.
With many years of crane manufacturing experience, Cranes Direct produce our own bespoke A-frame gantry systems to a high specification. They all meet BS standards and conform to EU regulations so you can be assured of quality lifting gantries.
Inspections and repairs are also offered by Cranes Direct and are carried out by our trained engineers. Inspections can be completed on site if required. As well as you’re A frame gantry other lifting equipment can be inspected and repaired too. We can custom make your a-frame crane to suit your requirements within the size ranges stated.
Here is a little more information on our A-frame gantry systems.
An A-frame Crane provides a great solution for lifting and lowering heavy and cumbersome loads. This is especially so in more awkward positions. Lifts can be carried out in a stable and safe manner. An A Frame Gantry can offer a great substitute to those big or permanently fixed, crane structures. Fixed cranes require lots of space, are much more costly and often unnecessary for something which may be used infrequently. An a-frame gantry system is much more cost efficient as they are not a permanent structure. If they are bolted down they can be classed as semi-permanent. They are also fairly easy to move to other locations or into storage if they are not needed.
What is an A Frame Crane or Gantry?
Common terms to describe an A Frame Gantry include; a frame lifting gantry, a frame crane, mobile a frame gantry or mobile gantry.
An A Frame Gantry is a type of crane which is not permanently fixed to a building structure like an overhead gantry crane is. Our A-frames consist of a horizontal beam supported by two “A” shaped end frames /legs. They are welded together by our highly experienced welders / fabricators for the strongest framework possible. All of our self manufactured cranes have had professional technical calculations and drawings produced to ensure their load bearing capabilities, stability and safety.
A-frame cranes are very similar to a mobile lifting gantry however they do not have any wheels and so cannot be moved around quite so easily. (Wheels can be added if required to make it into a mobile gantry system). The A Frame crane has special plated feet which may be bolted directly into the floor for extra stability, this is ideal if the gantry is to be used in one position most of the time.
It is possible to remove the bolts at a later date if the gantry needs to be moved to a new location, where it can be re-bolted down as necessary. A-frame gantry systems can be used just as efficiently when not bolted down. This enables the gantry to be moved to different work areas with the aid of a few people.
Therefore they are the perfect solution to lifting loads in more than one place within your working environment. So if you need to lift heavy loads, often in different work areas, or do not wish to permanently change your working area with a fixed overhead crane then an A Frame crane could be what you need. They provide a non-permanent, cost effective and efficient means to lifting heavy loads.
How Is an A Frame Gantry Crane Used?
A-Frame cranes are easy to erect and take down if and when necessary. These cranes consist of just 3 main components which are simply bolted together. This modular system allows them to be transported to a completely different site on the back of a lorry if needed. Subsequently re-erecting it by fixing and securing the main bolts on each leg to the top horizontal beam.
A-frame gantry systems are used by positioning the frame above the load to be lifted. When the gantry is bolted down and secure the load will need to be taken to the gantry. Whereas an unbolted gantry can be taken to the load. Therefore you have a choice! Do you use the gantry in one location more often than not, if so the best option would be to bolt it down. If you need it in multiple locations but do not want it bolted down, nor have wheels fitted, then a plated feet but un-bolted option will work best for you.
The load may then be fixed to the desired lifting appliance which has been safely fitted to the horizontal beam. Beam clamps or beam trolley’s together with a hoisting device are the most common choices. Cranes Direct can supply any type of beam attachment and hoisting device to compliment the a-frame crane. We are your one stop shop for all types of cranes and lifting equipment.
It is most important as with all lifting gear products to check them frequently. Look for any flaws which could seriously impede its lifting capabilities and safety. Things you should be looking out for include cracking in welded joints, deformed or dented beams, loose bolts, debris on the runway etc. And of course you should also check other lifting devices and equipment in the same way. If there is any doubt over the safety of the device then get it inspected and tested by a competent engineer before use.
Due to the fact that these lifting gantries can lift tremendously heavy loads they must be inspected and tested at regular intervals. Thorough inspections should be carried out on a yearly basis, or sooner, depending on how it is used. This must be carried out by a qualified person. Load testing should also be carried out to ensure it is up to the job of lifting to its safe working load limit. This should be without any difficulty, and therefore ensuring the safety of your gantry.
Cranes Direct engineers can carry out these legally required inspections as well as repairs, installations and servicing. Full certification and necessary documentation will be issued on completion of any inspection.
It is extremely important to note that an a-frame crane should NEVER be moved whilst under load. Moving a loaded gantry is a very dangerous practice and may cause the gantry to tip over, causing serious harm.
Key Benefits of an A-Frame Gantry
An A Frame Gantry has many benefits and can be the perfect solution to heavy lifting. Commonly used in a wide range of industrial sectors, as well as smaller workshops etc. The non-permanency of these gantries means much smaller layout costs than a fixed overhead crane. A-frame’s also do not require structural surveying to ensure the building’s stability.
An additional benefit to using a mobile A-frame lifting gantry is the vast array of additional devices that can be used on the gantry. This is important as the lifting gantry itself is really only the load bearer. Additional lifting equipment will be needed to actually lift and lower the loads. Most lifting gantries will need a beam clamp which fixes to the horizontal beam in a fixed position. Alternatively a beam trolley which can be moved across the beam when needed. These can be manual or powered for extra ease of use.
It is to these beam fittings that you can affix numerous other lifting appliances such as an electric hoist, lifting magnet, lever hoist or a chain block. It is these appliances that will actually lift the load.
Other beneficial additions could be isolator switches for extra safety with electrically powered equipment and leather suspenders to hold the cables out of the way. Parking jacks and castors are also an optional addition.
