DS-SERIES DUOSCREED — GENERAL INFORMATION
Introduction
The Whiteman DuoScreed is a hand held vibratory screed
designed to strike-off and consolidate concrete slabs. It is
comprised of two major components, the power unit (gasoline
engine), and the strike-off blade.
Generally this screed
operates ideally in concrete with a slump of 2 inches or
greater . Its applications include patios, driveways, sidewalks
and floor slabs.
Assembly
There are no tools required to assemble the DuoScreed. The
power unit (engine) is connected to the to the blade by means of
a spring-loaded clamp. Springs within the clamp assembly
prevent vibration from loosening the power unit from the blade.
Engine
The Whiteman DuoScreed is equipped with an Honda Model
GX31SA, 1.5 HP, mini 4-cycle gasoline engine. This engine is
lightweight and requires no fuel mixing.
Drive System
The Honda 1.5 HP engine drives a flexible shaft that requires no
greasing. Its short one piece design runs directly to the vibrator
housing and does not bend. This type of design eliminates a
major source of friction and reduces the likelihood of shaft failure.
Handle Adjustments
The handle assembly on the DuoScreed is height adjustable for
operator comfort. The handle design used on this screed allows
the operator to remain upright at all times and can be quickly
adjusted without any tools.
Vibratory System
The vibratory system of the DuoScreed produces low amplitude
high frequency vibrations, designed to level and compact
concrete. This vibratory system is mounted at an angle to transmit
vibration laterally and vertically through the blade to produce a
strong, dense slab.
The engine drives a two piece eccentric weight by means of a
one-piece flexible shaft. This weight produces a vibratory action
which simultaneously allows the DuoScreed to level the slab
and consolidate the concrete beneath the surface.
Blades
The DuoScreed can utilize blades ranging in lengths from 4.9 to
19.6 feet (1.5 to 6 meters). Since different length blades will
require varying amounts of vibration, the DuoScreed features
adjustable eccentric weights. It is also recommended that two
power units be used if 16, 18, or 20 foot blades are required.
The blade of the DuoScreed offer a unique design with two
distinct edges and is manufactured from reinforced extruded
aluminum alloy. A curled edge is provided for applications that
allow the blade to ride on top of forms or rails. A smooth edge is
provided for wetscreed applications where the machine rides
entirely on concrete. Plastic end caps allow the blade to maneuver
around obstructions without marring the surface.
Maneuverability
End caps are provided on each side of the DuoScreed's blades
to allow the screed to be easily maneuvered around pipes or
obstructions.
Transport
To transport your DuoScreed simply unclamp the power unit
from its base. Additionally, the handles can be folded down for
storage. The power unit weights approximately 34 pounds while
the blades weigh approximately 2.8 pounds per foot.
