Stow SFG10E manual Beam Flail, Pentagonal Flail

FIGURE 7

Suggested Applications:

1)Removal of thin coatings and encrusted accumulations.

2)Cleaning concrete and asphaltic surfaces

3)Removing thick material build-ups of greases, paints, oils, vegetable powders and some resins from floors.

4)Light scarifying prior to the application of coatings, toppings or sealers.

The star flail should be replaced when the outside diameter is worn to approximately 1-5/16 inch or the inside diameter elongates to approximately 3/4 inch.

Beam Flail

The beam type flail is manufactured from high carbon steel that is through hardened for additional service life. It is highly effective for scabbling or scarifying and delivers medium to coarse surface finish texture. FIGURE 8.

Suggested Applications:

1)Medium duty asphalt and concrete scarifying.

2)Descaling steel decks.

3)Removing thick material build-ups of greases, paints, oils, vegetable powders and some resins from floors.

4)Dried, fully cured, carpet and tile adhesive removal.

The beam flail should be replaced when the outside diameter is worn to approximately 1-5/16 inch or the inside diameter elongates to approximately 3/4 inch.

Pentagonal Flail

The pentagonal type flail is manufactured from high carbon steel that is through hardened for additional service life. Each section of the five sided design features a small, tungsten carbide insert that is held in position with copper brazing. It is highly effective for scabbling or scarifying and delivers medium to coarse finish texture. FIGURE 9.

Suggested Applications:

1)Heavy duty asphalt and concrete scarifying.

2)Heavy duty descaling of steel decks.

The pentagonal flail is designed for more aggressive and rapid removal of a surface in comparison to the beam flail. The addition of the tungsten carbide inserts contributes to its long service life and higher production rates. The use of tungsten carbide is also the main reason for the cost differential between it and the other flails. The design configuration yields a rather coarse surface finish and texture. For many job applications, this finish and texture will be satisfactory. Some applications may require an additional smoothing process. If the resulting surface finish is too coarse to meet specifications, it can be smoothed with the use of the star or beam flail.

COST 10 PRODUCTIVITY 8 SERVICE LIFE 10

The pentagonal flail should be replaced when two successive tungsten carbide inserts break off or the inside diameter elongates to approximately 3/4 inch. In service, the flail body will wear much faster than the tungsten carbide inserts. The copper brazing used to weld the inserts into the body can fail and an insert break off. The flail can still be used in service. It will just wear a little faster and more uneven in
