5. Clean Air Cabs
These are cabs that cover the operator’s station from about the seat area
upwards. They are not sealed, but rely on the positive pressure of a forced
air blower to keep chemically contaminated air from infiltrating the cab.
They draw air in from the front of the machine, through a series of
particulate and charcoal filters to insure fresh air is being blow over the
operator. While these cabs do not obviate the need for respirators worn by
spray technicians, it provides a much healthier environment for them.
6. Electric Lift Booms
Booms can be ordered with electric lift actuators to raise and lower the left
and right boom wings. It enables the operator to transport and spray
without getting off the machine. It also lets the spray tech lift and lower the
boom to match changes in contours of terrain.
7. Enclosed Boom Systems
Enclosed boom systems use is going to see a leap in growth in the next
few years and Smithco wants to be at the forefront of this
development. Enclosed booms do the following:
• Permit spraying in windy (or windier) conditions by reducing the
opportunity for drift.
• Protect the operator, the golfing member, and the environment
plus reduce liability risks.
• Provide an increase in efficiency by more accurately applying
chemicals when they’re needed, regardless of weather
conditions.
They can be electric or manual lift and should include some way to indicate flow to each tip to ensure
the spray pattern is being applied correctly.
8. Air-gap fillers
Air Gap fillers are required in many municipal districts to prevent chemical
from siphoning back into the water system through the filling hose.
9. Fresh Water Wash Tanks
Fresh water wash tanks are small (3-9 gallon) tanks mounted on a
sprayer to allow the operator to have clean, fresh water available in the
event there is a spill of chemicals on the operator, or to rinse out eyes
that may have come in contact with a chemical.
10. Automatic Air Bleed Device
This device is intended to allow the non-self-priming centrifugal pump to
re-prime itself with low volumes of material in the tank. A fitting is
installed in one of the pipe plugs on the pump casing and a small hose
is run to the top of the tank to allow air to bleed back up into the tank,
eliminating the loss of prime problems usually associated with
centrifugal pumps.
11. Low Pressure Alarm System
If air is sucked into the suction side of the pump, as when the tank is emptied, this device senses the
pressure drop and through a transducer, sends a signal to a warning alarm located at the operator’s
station. This alarm sounding allows the spray tech to shut off the pump before damage can be done to
pump by running it dry.
