Harrison
Hydra-Gen Model 6.0/8.0/10.0 MCR
Specifications
The generator shall be one (1) Harrison MCR Hydraulic
Driven Generator rated at 6,000 watts, 25/50 amps,
120/240 VAC, 60Hz, 1-phase.
OR
The generator shall be one (1) Harrison MCR Hydraulic
Driven Generator rated at 8,000 watts, 33/66 amps,
120/240 VAC, 60Hz, 1-phase.
OR
The generator shall be one (1) Harrison MCR Hydraulic
Driven Generator rated at 10,000 watts, 82/84 amps,
120/240 VAC, 60Hz, 1-phase.
The generator shall be designed and assembled by a
company with no less than 20 years experience in the
manufacture of hydraulic driven generators.
The generator components shall be housed in a
structural steel frame which affords protection to the
components and provides a unitized mounting module.
The generator shall have top access to the oil
filter, oil fill tube and electrical interface box.
The hydraulic oil reservoir shall include an oil
level sight gauge visible from three sides; an oil
temperature gauge; an oil fill cap; an oil filter and an
internal venturi boost unit to provide positive pressure
to the pump suction port.
The hydraulic oil reservoir shall be shipped attached
to the structural steel frame. The hydraulic oil
reservoir shall have an option to be remote mounted if
required.
The generator shall have a cover consisting of NFPA
approved diamond tread plate.
A meter package that provides the frequency, voltage
and amperage of each leg shall be provided.
The generator shall not utilize electronic controls
or a multiplex system to control the frequency.
The generator shall include a bypass solenoid to
remotely turn the generator on/off with a 12 VDC signal.
The generator shall be a commercial type with a
heavy-duty bearing and of brushless design to ensure low
maintenance. No brushes or slip rings shall be allowed.
The generator and motor shall be close coupled and
aligned using a Morse taper with a through bolt to
secure the motor to the generator. No two (2) bearing
generators shall be permitted.
The system shall be capable of producing the full
nameplate power when driven from the vehicle PTO from
idle to maximum engine speed.
The generator shall be able to be used while vehicle
is either stationary or in motion.
The generator shall provide an option for a self
sealing air intake to prevent re-circulation of exhaust
air.
The generator shall provide an option for a vertical
exhaust fan in addition to the air intake fan. Single
fan systems shall not be allowed.
The generator shall provide a dedicated air intake
duct for the alternator and a dedicated air intake duct
for the heat exchanger. Both air intake ducts shall be
located on the same side of the generator.
The hydraulic motor and pump shall be of axial piston
design to provide low internal leakage and a high degree
of frequency stability. Gear motors shall not be
allowed.
The hydraulic pump shall match the system with the
proper orifice, pressure compensator, and load sense
settings to provide stable output regardless of engine
rpm or electrical load demands. Use of electronics to
control the flow shall not be allowed.
The system shall be capable of normal operations
using a commonly available premium hydraulic oil; Mobile
DTE series or equivalent. All fluid service points shall
be in close proximity to the reservoir for ease of
scheduled maintenance.
When properly installed, the system shall be
warranted for a period of not less than two (2) years or
2000 hours, whichever should come first.
The generator shall be tested at the full nameplate
rated load prior to shipping and the test report shall
be included. The test report will document the
generator's performance at various loads from no load to
full load to ensure reliable power delivery at those
loads.
