The above ratings shall be based on average weight of personnel on the ladder at 250 pounds each. The
ladder must meet the 2:1 safety factor requirement for material based on the weight of the ladder plus a 1,000
pound live load at the platform, flowing 1,500 GPM of water at 90 degrees to the side of the platform at zero
degrees elevation.
WATERWAY SUPPLY PLUMBING FROM PUMP TO REAR
Plumbing shall be installed from the fire pump through a tee at the aerial waterway and to the rear of the
truck. A 4" aluminum pipe shall be installed in the torque box with 4" Victaulic couplings on both ends.

back of the truck and under the torque box. The inlet/outlet will be located to the right hand center of the
vehicle.
4" WATERWAY SWIVEL
There shall be a 4" waterway swivel with 360 degrees continuous rotation. It shall be installed through the
turntable and torque box to connect the aerial waterway plumbing from the water pump to the aerial. The
hydraulic oil for the aerial shall be directed through a three-port hydraulic swivel with 360 degrees
continuous rotation.
TELESCOPING WATERWAY -- PLATFORM
A aerial waterway shall be provided from the base of the aerial device to the tip of the fly section. The aerial
telescoping aluminum waterway shall be fabricated of aluminum and shall have four (4) tubes as follows:
