Abstract

A forward-mounted fluid-dispensing boom on a fire-fighting vehicle that can move between a retracted position and a fully extended position directly in front of the vehicle.

Claims

1. A forward-mounted fluid-dispensing boom on a fire-fighting vehicle comprising:

a rigid frame forming at least a portion of the front end of the vehicle;

a hollow fluid-carrying extendible boom mounted on said rigid frame in substantially the center thereof for selectively receiving fire-fighting fluid and being extendable in an axial direction along the length of the boom between a first retracted position adjacent the vehicle front end and a second fully extended position in front of the vehicle, said axial direction having both a horizontal and a vertical component; and

a fluid dispensing nozzle pivotally attached to the outer end of the fluid-carrying boom in fluid-receiving relationship for controllable movement in at least one plane.

2. The forward-mounted fluid-dispensing boom of claim 1 further comprising:

a hollow collar pivotally mounted on the rigid frame portion of the vehicle for slidably receiving said boom and for movement in at least one plane; and

said collar being pivotable in said at least one plane when, and only when, said fluid-dispensing boom is substantially fully extended.

3. The forward-mounted fluid-dispensing boom of claim 2 further comprising:

first power means coupled between the frame portion and the pivotable collar for selectively and pivotably moving said collar in said at least one plane to cause movement of said fluid-carrying boom in said at least one plane; and

a position sensor mounted on said vehicle and coupled to said power means so as to detect when said fluid-carrying boom is substantially fully extended and then generating a signal that will allow the collar to be pivoted by the first power means thereby pivoting the fluid-carrying boom.

4. A forward-mounted fluid-dispensing boom on a fire-fighting vehicle comprising:

a rigid frame forming at least a portion of the front end of the vehicle;

a hollow fluid-carrying extendible boom mounted on said rigid frame in substantially the center thereof for selectively receiving fire-fighting fluid and being movable between a first retracted position adjacent the vehicle front end and a second fully extended position in front of the vehicle, said hollow fluid-carrying extendable boom comprising at least a first section rotatably mounted at one end to the center of the rigid frame in front of the vehicle for rotation in substantially a horizontal plane and for selectively receiving fluid;

first power means coupled between the vehicle and the first hollow fluid-carrying section for pivotally moving the first hollow fluid-carrying section between a retracted position adjacent the front end of the vehicle with its longitudinal axis perpendicular to the longitudinal axis of the vehicle and a forwardly extending position in front of the vehicle with its longitudinal axis in axial alignment with the vehicle longitudinal axis; and

a fluid dispensing nozzle pivotally attached to the outer end of the fluid-carrying boom in fluid-receiving relationship for controllable movement in at least one plane.

5. The forward-mounted fluid-dispensing boom assembly of claim 4 further comprising:

a second hollow fluid-carrying section pivotally attached to the other end of the first hollow fluid-carrying section for movement from a first position parallel and adjacent the first section to a second position in axial alignment with the longitudinal axis of said first section and extending in front of the vehicle.
