Broom Storage
The broom portion of the Terramite Street Sweeper should
be stored away from direct sunlight. Prolonged exposure
to sunlight greatly reduces the life of the bristles.
Do not leave broom head lowered with weight on the bristles
when not in use. Weight on the bristles for long periods of
time will cause the bristles to become permanently
deformed, resulting in lowered sweeping effectiveness.
1/2 Poly - 1/2 Wire Wafers (Standard)
1/2 Poly and 1/2 Wire Wafers are used for
varying sweeping conditions. The 1/2 and
1/2 combination is used to sweep
throughout the year without changing
cores. This combination is the most used
approach. Eight foot brooms require 24
poly and 23 wire wafers and six foot
brooms require 19 poly and 18 wire wafers
Poly Wafers
For normal sweeping operations, such
as sand, dirt, paper, etc. This wafer
will be the best for dry sweeping.
Maximum 3" brush pattern.
Wire Wafers
For hard material sweeping, such as
concrete curing, mud, rock, snow, etc.
This wafer is the strongest wafer
available and with the sharpest cutting
force. For snow usage the ends pierce
the snow and ice quicker than poly wafers. This quickness
requires less down pressure.
Maximum 3" brush pattern. Exceeding this pattern will
lead to wire breakage, excessive wire wear, and short life
of the wafers.
Brush Wafer Wear Life
The brush is one of the most important parts of the sweeper
and its operations. The brush is a replaceable component
that literally performs the hard work.
EXAMPLE OF WEAR LIFE
Fine Asphalt ............................................................................. 1 Year
Finish Coated Asphalt ............................................................ 6 Mos.
1st Pass Asphalt ................................................................. 3-4 Mons.
Milling (Ground up road surface) ....................................... 1 week
These number will be greatly reduced if used in an incorrect manner.
Proper Care and Use of Broom Wafers
Factors for Longer Brush Life.
1. BROOM LEVEL
A broom not level with the sweeping surface may
cut wafer life in excess of 50%.
For maximum broom wafer life the level of the broom
must be checked daily. The time spend in checking
and correcting the broom level will pay in the
extended life of the broom wafers.
2. TURNING BROOM CORE
Turning the broom core from end to end during the
life of the brush will also extend its life. This turning
helps prevent uneven wear caused by sweeping
material from the same side, refer to page 2.17.
3. BRUSH DOWN PRESSURE
The most common reason for short brush life is too
much down pressure. By using the proper amount
you can obtain maximum brush life.
The best sweeping action occurs by the "flicking"
action of the bristles at their tips. By applying too
much down pressure the bristles are using their
"sides", this action greatly accelerates wear and
reduces sweeping efficiency.
To limit down pressure, Terramite Street Sweepers
are equipped with an adjustable spring assembly.
Proper adjustment is shown in Figure 1.
4. PROPER GROUND SPEED
Proper ground speed is important for the life of the
brush. Running the machine too fast may allow
material to accumulate in front of it. This build up of
material creates pressure on the bristle "sides", which
leads to their "wear".
For proper operation, sweep at high enough brush
speed to discharge material and with proper ground
speed to discharge the swept material from the
sweepers path.
