General Information
The Franklin Hydraulic Power Unit is designed for many years of safe trouble
free service. FRANKLIN offers several options in the hydraulic power unit series.
Hose control harness assemblies are available in up to 60 foot lengths. Each power
unit is specifically developed to handle the needs of a custom made fabrication line.
The Franklin Series 250/500 Hydraulic Units are electric solenoid operated for
optimum performance. These units have a fixed displacement developing up to 5000
PSI. The hydraulic pump is driven by an industrial grade, ball bearing, 3 phase, C
phase electric motor with magnetic starter. Standard power units have one (1), two
(2), three (3), or four (4) valves per unit. More valves can be added at the request of
the customer.
Solenoid valves are employed on all Franklin Hydraulic Units. Electrical
control provides the most versatile and inexpensive method of hydraulic control. In
most units, a double solenoid, three position, spring centered valve is used to control
each hydraulic press. Upon solenoid activation, the oil flow is channeled to the
respective work load. The hydraulic valve spool type is determined by its specific
application.
All hydraulic power units developed by Franklin are powerful devices and
should be used with great care. Before operating any device with a power unit, the
operator shall read and understand all instructions in the operations and maintenance
manual including safety procedures.
WARNINGS : In keeping with standard safety practices, the
manufacturer recommends the use of eye protective equipment during
the operation of this machine.
The power unit must be OFF during any maintenance or tool change!
Supervisors shall lock the main disconnect in the OFF position to avoid
injuries.
