CRANE INSTALLATION 1300A
9-20 01-22-2019 Control # 051-08
Oil Cooler Fan Electrical Connection
The oil cooler fan is connected to the truck battery as shown
in Figure 9-15.
Hydraulic System Connection
The hydraulic system pressure is supplied by a three section
hydraulic gear pump mounted on the truck power take off
(PTO). The pump is driven counter clockwise and supplies
the following at 1800 rpm:
• P1 supplies 34 gpm (128.7 lpm) at 3300 psi (227.5 bar)
for the hoist circuit.
• P2 supplies 29 gpm (109.7 lpm) at 3600 psi (248.2 bar)
for the telescope and lift circuits.
• P3 supplies 12 gpm (52.9 lpm) 3000 psi (206.8 bar) for
the outrigger and swing circuits.
Connect the hydraulic hoses to the pump sections as
marked.
15. Adjust the throttle for the engine RPM and PTO ratio to
get proper pump shaft speed.
16. After all cylinders have been cycled, stow the crane and
place the outriggers in the up position. The oil level
should be visible near the top of the sight gage.
17. Lift and stability test must now be performed on the unit.
Hoist and crane tests need be conducted to insure
proper performance.
18. After the stability test is complete, check the T-box and
turret mounting bolts for proper torque.
19. Measure the overall height of the crane and truck. Post
the overall height measurement inside the truck cab to
inform the driver of the overall height.
