Ladder and Water Tower Combined
For the city of Los Angeles, Cal., the Underwriters have insisted that water tower respond on first alarm to the high value district. A special water tower crew was provided, but for the past two years the tower was only used three times.
To meet the requirements of the Underwriters and at the same time to provide a truck having greater utility, Chief Scott decided that the water tower should be combined with a ladder truck.
To give the crew complete protection a 4-door all-steel sedan type cab accommodating seven men is provided. The water tower will extend to a height of 65 feet and the nozzle is provided with four sizes of tips, 1 1/2, 1 3/4, 2, and 2 1/4inch. With the 2 1/4-inch tip it is thus possible to discharge 2,000 g. p.m.
Three controls are provided on the mast for rotating the nozzle and elevating and lowering the nozzle. In addition to these nozzle controls, the whole mast may be rotated from the turntable on the platform ami the mast may be raised or lowered to any desired position. The mast is spring raised and can be put into operation quickly and at any angle required for efficient use.
The mast can be inclined at an angle that will permit the nozzle to discharge directly into a window and thus in cases where high wind prevails the stream from the nozzle is not broken up, but full benefit is obtained from the water.
There are four inlets, 3 1/2-inch diameter, with clapper valves, which give an input capacity to the tower equal to eight 2 1/2-inch inlets. This design is in keeping with the practice of Chief Scott of having the minimum number of hose lines in the street.
When the tower is in action, stability is provided by a sliding type of frame chock on the tower truck frame which permits a wide spacing of the supports. When the mast is in the bedded position, it provides no interference with the vision of the tillerman at the rear.
The tillerman’s seat and protecting windshield with the steering gears is offset to the right so that a minimum overall height is obtained and yet the tillerman’s vision is not obstructed.
A total of 403 feet of ladders are carried on the truck. This is a greater footage of ladders than usually found, but provides the maximum of utility for a vehicle of this type. In addition, life nets and other equipment are also carried.
