DSGPULW DUOSCREED — GENERAL INFORMATION
Introduction
The Multiquip 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.
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 various blade widths. The type of
blades are defined as
heavy duty
(HD) or
lightweight
(LW).
The widths can range anywhere from 6~20 feet (1.82~ 6.00
meters). See Table 1 for more detailed information. 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 18~20 foot (5.48~
6.0 meters) blades are required.
Engine
The Multiquip DuoScreed is equipped with a Honda Model
GX35SAT, 1.6 HP, mini 4-cycle gasoline engine. This engine is
lightweight and requires no fuel mixing.
Drive System
The Honda 1.6 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.
Maneuverability
The HD blades have
end caps
and are available in the lenghts
referenced in Table 1. End caps are provided on each side of the
DuoScreed's blades to allow the screed to be easily maneuvered
around pipes or obstructions. End caps are not used on the LW
blades.
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 weighs approximately 29 lbs.
(13.0 kg), while the HD blades weigh approximately 2.8 lbs/
ft. (4.2 kg/m) and the LW blades weigh 1.95 lbs/ft (2.9 kg/m)
Figure 2 shows the location of the components of the
DuoScreed. The function of each component is described
on the next page.
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.
Some blade widths may not be
available. Please contact MQ unit sales
for available blades.
