Instructions & Technical Information

Custom systems can be designed to move up to 20,000 lbs. and are ideal for lifting, moving and positioning heavy equipment and industrial machinery.

In our example we will use four 24 x 24 quads to move a 10,000 lb. load.

Load capacity is highest on very smooth floors and decreases with increasing floor roughness. As demonstrated by the side chart, the system can easily move 10,000 lbs. on a highly finished sealed concrete floor but might only move 600 lbs. on tightly rolled asphalt.

Floor surfaces can be temporarily improved by laying down a sheet of paper, plastic film, masonite, sheet metal or similar nonporous materials. These materials are usually available at home supply stores or can be ordered through Airsled. When planning frequent moves over a poor floor surface, you could apply an industrial grade floor coating on the floor to make the move easier.

Airsled air moving equipment systems are designed so most loads can cross 3/4″ cracks on a smooth floor at the maximum rated load capacity. Lighter loads can negotiate wider cracks and gaps. Wide cracks and gratings can be bridged with a layer of sheet metal. When the load is pushing the limits of capacity, cracks are more difficult to move across.

Load Placement

Be sure to place the air beams under a part of the load that is strong enough to support the weight above it, avoiding weak areas such as heater coils or thin sheet metal.

1. If the load is flat on the floor, use one of the following methods:

a. Use a pry bar to raise each corner of the load enough to place an air beam underneath. If necessary protect the floor from the pry bar and do not exceed floor loading capacity when pressing down on the pry bar.

b. Use a pry bar to raise the load enough to place shims under the load and then slip the air beams in place. As an example, if the air beam is 3/4″ high use a 1″ shim.

2. If the load is on feet or legs 1″ high or less: Slide the air beams under the load with placement as recommended in the diagram provided with the system.

3. If the load is on feet or legs more than 1″ high:

Use spacers such as 2X4s or 4x4s on top of the air beams. The top of the spacer should be 1/4″ from the bottom of the load.

Blowers and Hoses

 

Connect the air beams to the blowers. The custom quad system consists of 2 or 4 blowers, each attached to hoses in one of the following arrangements:

One 3-foot hose (or specified length) connects each blower to a T fitting. Two 3-foot hoses (or specified length) connects the T fitting to the two air beams.

If using one blower for lighter loads:

Connect one blower directly to T fitting, then connect two hoses to the other ends of the T fitting. Now place two additional T fittings giving you four hoses to connect one end to each air beam.

If using 4 blowers

One hose is connected to each blower and then each one is connected to each air beam.

Make sure all hose connections are secure. Hose clamps are provided for the four female hose cuffs that connect to the blower and the T-fitting. Accidental disconnection could possibly jar sensitive loads.

Use only grounded extension cords and do not remove the grounding pin from either the blower cord or the extension cord. The blower may be hand held, carried by the shoulder strap, or secured to the load. The blower may rest on the floor for short moves.

Balance Check

Turn on the blowers without moving the load. Check all corners and edges of the load to make sure there is at least 1/2 inch of clearance between the bottom surface of each air beam’s backing surface and the floor (see illustration). Pushing down at each corner is an easy way to judge proper air beam inflation and clearance. If a corner or edge does not have adequate clearance, the load is not properly balanced and must be readjusted.

Proper balancing may be harder to achieve with higher centers of gravity. Balance can be adjusted by repositioning the air beams toward the heavier side. The two blower, four air beam arrangement is sufficient for most loads. A one blower, four air beam arrangement provides less stable balance. A four blower, four air beam arrangement provides the most stable balance.

Caution: Moving an air beam with a corner or edge dragging will make movement difficult and reduce service life.

Moving the Load

Turn blower on and then remove any shims before moving the load. Apply even pressure with both hands, adjusting leverage on the load as needed. A slight downward pressure will keep the unit from “rolling” toward the leading edge.

Push the load slowly; excessive momentum requires longer stopping space. Be careful not to run over the power cord.

Stopping

 

Move the load to the desired location, making sure the shims are properly placed to receive the load. Make sure it will not be sitting on the power cord or any other objects when the blower is turned off.

Turn the blower off and allow load to gently settle to the floor or onto the shims. To avoid unnecessary wear to the bottom of the air beams, always bring the load to a stop before turning off the blower.

Remove shims with a pry bar.
