Air Skates Lifting Equipment

In the traditional past – back in the day, machine moving tools included castors, wheels, skids and sleds all of which had to be pulled along by a forklift truck or similar. And as they traveled across floor surfaces, these tools caused no end of damage to the floors. Those days should be in the past for modern machine companies, who can now take full advantage of Air Skates Lifting Equipment.

The modern way of moving machines is by using air skates. Air skates lifting equipment fits snugly underneath the machines to be moved.

An air skate is a series of components that fir together to form a air skate module. The main component of the air skate is the air bearing which is fitted to the bottom of the module. See images below:

Air Skates lifting equipment and machine moving casters are the perfect choice for moving heavy machines in industrial locations. A Hovair Systems article written by David Roberts. Air Skates lifting equipment and machinery moving casters are the perfect choice for moving heavy machines in industrial locations.

The black diaphragm fitted to the bottom of each module is the powerhouse of the whole exercise. It is what defines the weight capacity of the air bearings and the size of the machines it can lift and move.

When a set of air skates are fitted underneath a heavy machine in order to move it, the skate modules are taking the weight of the machine. Air skates lifting equipment is designed to operate pneumatically with compressed air. When air is powered into each air skate it causes the air skate to inflate. When the skate is fully inflated the excess compressed air is then repelled back by the floor surface and this causes the air skate to rise and float on the floor surface. When in flotation state, the machine will be lifted and can then be moved off to a different destination.

The image above shows a heavy Caterpillar machine being moved with Hovair Systems air skates lifting equipment..

When it comes to lifting and moving heavy objects and machines, there is little to compete with modern air skates lifting equipment.

Air skates lifting equipment is available in sets of four or six air skate load modules. The only power source needed is compressed air which most industrial locations have in-house to power other tools. Using only compressed air (pneumatic), air skate lifting equipment can produce tremendous lifting power to handle the largest and most awkward heavy objects and machines.

Air skates – also known as air casters, air cushions and air sleds – are the usual tools of choice for moving heavy objects and machines. They can easily out-perform any forklift or overhead crane in most indoor locations. With weight capacities starting at 1000 pounds, they can range right up to 100 tons and all points in between.

There are not many machines that an air skate machine moving system cannot handle.

The versatility of air skate lifting equipment allows them to be placed in strategic positions beneath the machines or heavy loads they are moving. This helps to take care of any uneven load distribution properties of the machine.

Air skate lifting equipment is very versatile in as much as its air skate are not required to have a fixed position underneath the machines they are moving. The great benefit to this is that you can move a machine that has differing weight proportions. For instance, one side may weight several tons more than the other side, and with the versatility of the air casters, they can be placed at the correct places beneath a machine to allow support under the machine in the correct places. You can use any number of air skates beneath many locations of the machine you are going to move.

Below right, is a diagram of a typical four-station air skate machine moving layout. These air skate positions can be altered to suit the weight of the machine they are going to use. Using as many air skate modules as you need, you can place them in different locations beneath the machine to suit the properties of that machine. There is very little that is beyond these tremendous load moving tools.

Air skates are used in series of four or six and assembled into complete air skate machine and lifting equipment via air line hoses, valves, tee-pieces and other hardware. See below, right.

This form of load moving is known as air film technology.

Rigging Equipment

Above you can see a typical footprint layout for rigging purposes using air casters to float machines instead of lifting them. This process is very SAFE and easy to use.

Hovair Systems has been supplying Rigging Companies all over the USA, Canada, and Central America with air powered rigging equipment and supplies for many years.

No Rigging Company should be without a Hovair air caster machine moving system in addition to the traditional rigging practices of chains and pulleys, etc. Hovair Systems has been able to offer an added dimension to the Rigger’s Toolbox… air powered lifting and handling equipment which is specifically designed to assist with the heavier loads… the heavy machines, heavy machinery, heavy objects, that usually present any rigging team with a challenge or two.

Rigging Equipment & Tools
Hovair Systems have a terrific selection of rigging equipment that should be in the toolbox of any rigging company. Air caster load moving equipment is a popular choice. Air casters are available in kit form and can be set up right out of the box for the rigger. Starting at weight capacities of one ton, they can range to take care of machines that weigh 50 tons or more. Hovair has a solution for any heavy machines that riggers need to move.

Rigging & Lifting Equipment
Hovair Systems has a wide range of rigging and lifting equipment available to rigging companies in today’s marketplace. As time and new technology arrives and moves on, there has not yet been anything to challenge the process of lifting and moving heavy machines on a thin film of air just above the floor surface. This is definitely the most cost-effective way of lifting and handling any heavy machinery you are being asked to work on.

Rigging Safety
Hovair Systems are top of the list when it comes to Safety in the Workplace. We constantly remind the operators of our equipment to closely follow the safety regulations of their company before they start work. We also throw in some good safety advice of our own for good measure. Before using any rigging equipment these days, you should always check your company’s safety regulations.

However, all Hovair Systems’ products are pneumatically driven (with compressed air) and the operation process only causes the machine that is being lifted to rise no more than 1-inch above the ground. There is nothing much safer than moving a load sitting an inch or so off the ground. However, compressed air in itself is a safety hazard and Hovair Systems makes note of this in all their operator manuals.

Pneumatic Powered Lifting and Handling
As previously stated, virtually all Hovair Systems load moving products are operated and fueled with compressed air. They need no other power source. This makes them so easy to use and operate. All products are versatile and modular making them the ideal lifting and handling tools for today’s modern rigging company.

The perfect complement to your arsenal of rigging tools and equipment – a Hovair Systems air bearing kit.

We have a great range of starter kits available complete with all hoses and necessary fittings. No additional extras to worry about and no worries about having the right hoses sizes and connections…everything you need in one easy package. The perfect solution for any rigging company.

Or we can supply kits that fit directly and permanently to your machinery. To move that 10-ton machine you simply plug in your airline and take it away. It really is that simple.

The top picture shows a typical air bearing and caster kit, with high lift bearings onboard, a remote control unit for central air flow control, and all necessary fittings. The caster modules of this kit are very thin and have a profile height of around 1ž inches – enabling them to slide under machines with low height clearance.

The bottom picture is of a typical round steel system that is designed to have the caster modules fitted directly to the machine itself. This is a tremendous tool for situations where machinery has to moved repetitively. Leave the modules permanently fixed to the machine and simply plug in your air line and move it instantly

You can move loads of up to 100 tons and more with virtually no effort at all.

Industrial Skates – Machine Moving Equipment

In today’s busy industrial environs, the use of Industrial Skates Machine Moving Equipment is being demanded more and more. This is because modern load moving techniques are available to make this once difficult task a piece of cake in today’s industrial marketplace.

Not so many years ago, unless you had some of those heavy mechanical dollies that could slide under your machinery, you could not move it without professional rigging companies being involved… and at a cost too. Then you had the problem of how much damage they were going to do to your floors. It was not a satisfactory exercise to move your heavy machinery around. Then came along air powered industrial skates which proved excellent for the moving of machinery.

One of the best and most cost-effective tools now available for heavy industrial machine moving is of the pneumatic type – air powered industrial skates machinery moving systems which can lift and move machinery up to 100 tons and beyond using only a little shop air that is probably readily available in your shop right now.

Here are two examples of heavy industrial machinery in the process of being moved to new locations.

Notice that both machines are being supported by Hovair Systems industrial air casters that are using powerful air powered, air bearings to lift and suspend the load on a thin film of air (technology) which allows the machines to effortlessly float across the floor surfaces to other locations. Initial set up needs some careful adjustments to make sure everything is correct and once the heavy machinery is floating on the floor surface, the rest of the operation is (that proverbial) a piece of cake.

While most air powered industrial machinery moving tools require certain standards and specifications to be present to ensure optimum operation, they are very versatile and can be placed in different locations to suit your heavy machinery moving needs.

These tools are very durable and strong and are therefore very adaptable to users’ needs. We have engineers all over the world that have adapted our products to suit their operations and these products are continuing to work for them day after day.

What is an air bearing and how does an air bearing work

Assuming you have read the What Is An Air Bearing Article, we can now take a look at how an air bearing actually works. We can see from the blow-up illustration below how an air bearing is assembled. But what happens next; how does the air bearing work.

Generally an air bearing load module is grouped with three or more other air bearings modules, and connected together to form what is knows as an load moving (or machine moving) system. Below is a typical load moving system footprint all ready to have a load placed on to it.

Yes, But How Do They Work?

Once the air bearing modules are formed into a footprint roughly the same size as the load they are going to move, it is time to introduce air to the system. This is done by connecting a compressed air supply pipe from the company’s compressor to the system’s entry point at the on/off ball valve. Making sure that all air flow control valves located on the side of each load module are fully shut, it is safe to turn on the air supply at the system entry ball valve. By doing this compressed air is allowed to flow to each individual load module. For this article’s purpose, we’ll take just one load module as an example, but the procedure needs to be done to all load modules in the system.

Choose a load module and open its air flow control valve about half a turn or so. See image to your right. You should hear the air starting to enter the load module. At this stage the compressed air will travel through a series of internal channels until it reaches the air bearing’s diaphragm – the black element of the module. When the diaphragm is reached the compressed air is forced to enter the diaphragm. Remember, there is a constant supply of compressed air forcing its way into the diaphragm at this time. This is why we need to be able to control and manage the air that enters each load module.

The amount of air allowed into the load module will depend on the weight capacity of the air bearings being used and the load going to be moved. This is why we have these air flow control valves to help manage the amount of air we’ll be using. When initially turning on the flow control valve we should do it incrementally with the other modules in the system – do each valve in turn the same amount. Eventually the correct amount of air will be reached and the load modules will start to raise and float the load off the floor.

When the incoming air reaches the (black) diaphragm this causes the air bearing to inflate – because of the incoming air trying to blow it up like a balloon. When the air bearing has inflated to its maximum for the weight being carried, the remaining air has nowhere else to go because of the pressure of the following compressed air. The air (like water) will search for an exit and it should quickly find the exhaust holes of the air bearing. You can clearly see the exhaust holes in the image to the right.

The load you are going to be moving should already be placed on the air modules before the air to the system is turned on. The load will be pressing down on the load modules. The modules cannot move at all because of the load’s weight. So when the air bearing starts to inflate, the black diaphragm expands downwards and forms a tight seal with the floor surface.

Below is a perfect example that illustrates how the air bearings work.

The air inlet simulated the position of the air flow control valve at the entry to the load module.

The load is already placed upon the load modules.

The air enters the air bearing at the inlet point and finds its way to an exit point inside the diaphragm.

As it enters the main diaphragm area it cause the air bearing to form a seal with the floor.

The seal is formed at the extreme edge of the load module – as shown.

The compressed air is eventually repelled away from the floor surface thus causing the air bearings to raise and take the load up with it.

When the air has raised to its limit, the excess air will escape from the sides of the air bearing.

The air bearing will retain sufficient air to keep the load floating.

 

Air Bearing Systems

Air Bearing Systems are essentially machine moving (and other load moving) equipment that have been designed to lift and move heavy machines within industrial premises around the world.

Air bearing systems are actually a set of air casters set up as shown to the right. Each air caster consists of several components which are fitted before it can be deemed a finished air caster.

One such component is an air bearing which is fitted to the underside of each air caster. The air bearing is the actual driving force part of air casters. Assuming for now though, they are air bearing systems. See image right.

Air bearings systems are a series of air casters and bearings that are assembled to form various types of load moving and machinery moving systems.

The word Air denotes that they are powered by compressed air (pneumatic) and use air film technology to cause them to operate.

Air bearings systems is selection of air bearings and modules that are assembled together using air hoses, tee-pieces, air manifold or air ball valve.

If you have a quick question or query or want more information, please use the quick contact box to the right and one of our support team will response to you as quickly as they can.

There are many variables that can make up an air bearings system. Weights can range from ½ ton thru 100 tons. Several air module types are available to produce an air bearings system of choice.
