Are Air Casters Safe To Use
Yes they are. One of the main benefits to using Hovair
air casters is that there is very little risk involved when using air
casters or setting them up.
In general, when air casters are energized with
compressed air, the fitted air bearing on the underside of the air
caster module inflates until it is full of compressed air. Air bearings
do not inflate like a balloon; it is more of a gentle inflation with
compressed air at around 13 psi. When the air bearing is fully inflated,
it will simply exhaust surplus air out through the sides of the air
bearing diaphragm. Air bearings do not keep on inflating until they go
bang. They are designed to lift only to a certain height and then stop
When the air bearings in a system, like the image
below, are energized with compressed air, the whole system of four air
bearings is designed to rise and lift the load clear of the floor. When
this happens, the load is still very close to the floor surface -
perhaps only a couple of inches or so depending on the type of air
bearing and modules being used. By being relatively close to the floor
when operating, there is very little chance of the load or machine being
able to topple over and sustain damage.
with any machine moving operation with Hovair Systems equipment, the
operator should always be safety minded, and this includes having
several assistants placed around the load when being moved. This makes
good sense and ensures that the machine and the assistants stay safe at
Naturally, in the case of higher loads or loads with
high center of gravity, the operator should be aware of the higher CoG
and the possibility of the load or machine toppling under its own
properties. With additional care these loads can also be moved in safety
and without incident.
The only time that a loaded air caster system could
potentially be in an unsafe position, is if the floor surface the system
is operating on is out of level and has a slight incline to it. If this
is the case, and even if the floor is smooth, polished and non-porous,
there will be a possibility that when the load is lifted away from the
floor and is in a state of flotation, it might have a tendency to follow
the path of the incline to a lower level. I this were the case, the load
would automatically do this without assistance from anyone. It'll do it
on its own. This is what we at Hovair Systems call "gravity drift."
There is absolutely no cause for alarm of any kind, and this is why we
always recommend having several assistants in attendance around the load
when it is being moved.
Hovair air casters are very safe to use.
