Description
Title: A Fire truck apparatus.
0 Barku-ound of the InvPntio~-Field of the invention.
The present invention relates to a fire truck a~pa~d~us.
More specifically, the present invention relates to a fire truck app~dlus which includes a tank for the transportation of water.
Tnformatior disclosure statement.
A fire truck al)pald~us for transporting water typically includes a tank which is filled with water for use in supplying fire fighting equipment at a scene of a fire.
In the event of a fire, large quantities of water must be rapidly pumped to fire fighting 2s equipment in order to assist in extinguishing the blaze.
However, with the prior art fire tankers, although capable of carrying several thousand gallons of water for transportation to the fire zone, such tankers suffer from a substantial drawback in that, as the level of water within the tank is depleted, the rate of flow of water from the tank decreases.
Moreover, when the water level has dropped to within a foot or so of the base of the tank, such water flow from the tank is extremely slow and insufficient to adequately serve the fire hoses and other equipment.
Additionally, when the water level within the tank has dropped, the rem~ining water within the tank is trapped within the tank if the fire truck is parked with the outlet thereof at a higher elevation than the opposite end of the tank.
The present invention overcomes the aforementioned problems associated with the prior art o arrangements by the provision of a fire truck having a tank that is pivotally secured to a chassis of the fire truck at one end thereof. Means are provided at the opposite end of the truck for pivoting the tank such that all the water therein is able to flow therefrom through an outlet.
Therefore, it is a plim~ objective of the present invention to provide a fire truck appalalLIs that overcomes the aforementioned problems associated with the prior art fire trucks and which makes a considerable contribution to the fire fighting art.
Another object of the present invention is the provision of a fire truck apparatus in which the tank pivots relative to the truck chassis so that all the water therein may be rapidly removed therefrom.
Other objects and advantages of the present invention will be readily appalellt to those skilled in the art by a careful consideration of the detailed description of a preferred embodiment of the present invention contained hereinafter taken in conjunction with the annexed drawings.
Summary of the invention The present invention relates to a fire truck al,pal~lus for transporting water. The apparatus includes a truck chassis and a tank secured to the chassis for the reception therein of the water.
The tank has a first and a second end, the second end being secured to the chassis about a pivotal axis.
Additionally, the tank defines an outlet disposed adjacent to the second end of the tank for o the flow therethrough of the water from the tank.
Lifting means extend between the chassis and the first end of the tank for lifting the tank such that the tank- pivots about the pivotal axis for permitting rapid and complete removal of the water from the tank through the outlet.
The lifting means includes hydraulic means connected to a source of pressurized hydraulic liquid and control means for controlling a flow of the hydraulic liquid from the source to the hydraulic means for controlling pivoting of the tank and the removal of the water therefrom.
In a more specific embodiment of the present invention, the truck chassis includes a single rear axle.
Also, the tank has a capacity of at least 2000 gallons.
In a preferred embodiment of the present invention, the first end of the tank is disposed in a forward direction relative to the chassis and the second end of the tank is disposed in a rearward direction relative to the chassis.
The outlet is disposed closely adjacent to the chassis so that the water is permitted to flow by gravity from the tank through the outlet when the outlet is open.
The lifting means is supported by the chassis, the lifting means having a first and a second extremity. The first extremity is supported by the chassis and the second extremity is secured to the first end of the tank about a further pivotal axis.
More specifically, the lifting means includes a first and a second hydraulic ram. A first 0 bearing is provided for bearingly securing the first hydraulic ram about a further pivotal axis extencling through the first end of the tank.
A second bearing bearingly secures the second hydraulic ram about the further pivotal axis which extends through the first end of the tank.
Each of the hydraulic rams is controllably connected to the source of pressurized hydraulic fluid and the lifting means further includes guide means rigidly secured to and extending upwardly from the chassis for guiding the tank during pivotal movement thereof about the pivotal axis.
The lifting means further includes a chain having a first and a second termination, the first termination being rigidly secured to the chassis. The second termination is rigidly secured to the tank for limiting upward movement of the tank during pivotal movement thereof.
2s The lifting means further includes an arm having a proximal and a distal end, the proximal end being rotatably secured to the chassis. The arrangement is such that during a maintenance operation when the tank is pivoted about the pivotal axis, the distal end is moved upwardly to lock the first end of the tank away from the chassis regardless of a disposition of the lifting means.
The control means is preferably connected to a hydraulic pump driven by an electric motor or driven by a power take off from the main motor of the fire truck apparatus.
