5.0 Product Selection and Application Guide
5.1 Match Type of Compactor to the Application
The Allied Ho-Pac is a vibratory plate compactor,
designed for mounting on mobile equipment with
hydraulic booms, such as rubber tired or track-type
construction vehicles. It is best suited for compacting
granular type soils by combining three actions:
x
Impulse Force
x
Vibration Frequency
x
Down Pressure (Static Weight)
5.1.2 Match to Compatible Size Carrier
The Allied work tool is designed to provide
satisfactory operation with reliable service life when
teamed with a compatible carrier. Balance the size of
the Ho-Pac with the size of the carrier. If too small for
the carrier, the compactor will be damaged by the
carrier. Conversely, too large a compactor can
damage an undersized carrier.
5.1.3 Other Considerations
x
Reach
- Select a carrier size having sufficient
reach to compact the deepest area of the trench
or excavation. This will also help minimize the
frequency of repositioning the carrier.
x
Lift Capacity
- Know how your machine is
equipped and if any modifications have been
made. Factors such as boom type, stick length,
undercarriage, tracks, counterweights, etc., all
affect the lifting capacity of the carrier. Also take
into account any add-ons, such as a quick attach
coupler. Consult the carrier manufacturer's
manual for specifications.
x
Hydraulic Circuit
- Select a carrier equipped
with a one-way hydraulic circuit and unrestricted
free flowing return. It must maintain adequate
flow and pressure without loss of hydraulic power
to the Ho-Pac while the carrier applies down-
pressure. If not, motor speed slows and soil
density targets won't be reached.
Undersized compactors (as well as underperforming
compactors) are less economical to use because
compaction is limited to smaller lifts and require
additional passes. This generates other inefficiencies
as longer running cycles result in loss of time,
increased energy consumption and component wear.
Optimum efficiency is achieved only when proper
operating technique is employed. How many passes
it will take, along with the duration, will vary with
material type and lift. Additional fill material and
repositioning of the carrier may be required to
achieve a finished surface.
5.2 Auxiliary Hydraulic Circuit
CAUTION
Hydraulic circuits differ between
machines. Improper oil flow or pressure
can damage the Ho-Pac or carrier.
Only qualified personnel, having knowledge of the
machine’s systems, proper test equipment and tools
should perform conversion set-up and adjustments.
The Allied Ho-Pac is a hydraulic-driven work tool that
is not self-powered. Satisfactory performance centers
on the hydraulic circuit of the host machine to deliver
proper flow and pressure requirements.
Generally, most machines will require some degree
of conversion to make use of their hydraulic power.
Conversions to machines equipped with a factory or
dealer installed auxiliary circuit, however, may require
little more than minor adjustments to flow and
pressure settings.
Carefully follow all instructions, including those
provided by the machine manufacturer, when making
adjustments.
5.3 Allied Auxiliary Conversion Kits
Fig 5-1 Allied Conversion Kit with AC-Series Valve
Allied conversion kits are available for almost any
carrier. For machines without an auxiliary hydraulic
circuit, the kit may include an "AC" series valve.
These solenoid-operated valves will control flow and
pressure to the work tool.
Requests for further information or assistance with
Ho-Pac selection or conversion kits should be
directed to your Allied dealer or by contacting Allied
Sales or Product Support Departments.
