1300A CRANE INSTALLATION
9
• A single front outrigger (SFO) is not necessary for 360°
stability if the mounting dimensions are maintained and
minimum rear axle and maximum front axle weights are
not exceeded.
NOTE:
• For smooth crane operation, a variable speed governor
and energize-to-run fuel solenoid on diesel tuck engines
are required. Electronic fuel injection is also required.
• All mounting data is based on a National Series 1300A
subbase and an 85 percent stability factor.
• The complete unit must be installed in accordance with
factory requirements, and a test performed to determine
actual stability and counterweight requirements. Contact
the factory for details.
• Transmission neutral safety interlock switch is required.
PTO REQUIREMENTS
Horsepower
A three section hydraulic gear pump is furnished with this
crane. The pump supplies 34 GPM (129 LPM) to the hoist,
29 GPM (98 LPM) to the boom, and telescope and 14 GPM
(53 LPM) to the turn and outriggers circuit. To provide these
flows, the pump shaft must turn at 1800 RPM. The PTO
requirement is a torque rating of at least 400 ft-lb (542 N·m)
or 76 HP (56.6 kW) per 1000 RPM of PTO shaft speed.
Direct PTO Mount
In most installations the pump can be mounted directly to the
PTO using adapter assemblies available from the PTO
supplier. If the pump is direct mounted, its weight should be
supported by a strap between the pump and the
transmission. The splined shaft coupling in a direct mount
pump installation requires lubrication. #200S Silver Streak
Special Multi-Lube (Medium) is applied to the shaft during
original installation and reapplied to the shaft or zerk
provided on PTO housing shaft semi-annually thereafter.
PTO Ratio
Pump shaft speed is determined by truck engine RPM and
PTO ratio:
Pump Shaft Speed = Truck Engine RPM x PTO Ratio
The following PTO ratio and engine speed combinations
provide proper pump shaft speed which is the recommended
maximum speed for the
1300A pump.
The speeds shown below are optimum operating speeds.
The engine must be operated at a speed such that the
horsepower developed is adequate to run the pump under
pressure and provide the required flow.
