ELECTRICAL CONNECTIONS
A 9 ft. electrical power lead - intended for 12V DC only - comes down through the center
of the crane base plate along with the hoses. This power lead should be slacked in the
compartment so that it remains relaxed throughout the 400 degree rotation of the crane.
A 20 amp circuit breaker is mounted on the crane and protects the crane's internal wiring
and solenoid coils. The 20 amp circuit breaker does not protect the 9 ft. power lead. For
added protection, the 9 ft. lead can be connected to a 20 amp protected circuit that, if
possible, is powered only when the vehicle engine is running.
HYDRAULIC FLUID
Average Climate Type of Oil
Cold to Moderate ISO Grade AW 46
Warm to Hot ISO Grade AW 68
The fluid should have the highest anti-wear characteristics and treated to inhibit rust and
oxidation.
HYDRAULIC HOSES & LINES
The minimum sizes for lines and hoses are as follows:
RESERVOIR
The PTO reservoir should have a capacity of 25 gallons fitted with 100 mesh suction
screen, 10 micron return line filter, and filler/breather cap.
PTO PUMP
The PTO pump should be sized to allow an engine idle speed range that will deliver
approximately 12.0 GPM for the HT45/55 VLC series cranes. These cranes' relief
pressures are set at 3000 psi.
PTO START-UP
Before connecting the PTO system to the crane pressure and return hoses, connect the
PTO pressure and return lines together at the bulkhead. Operate the PTO system for
about two (2) minutes per gallon of reservoir capacity (25 gallon reservoir = 50 minutes)
to flush out the lines and filter all the fluid several times.
ENGINE START/STOP & THROTTLE CONTROL
If your crane was purchased with optional engine start/stop and throttle control, refer to
drawing 22615 in the replacement parts section for further information.
