A boom section includes a first, a second, a third, and a fourth fiber reinforced thermoset composite material layer and a flex core layer. The first fiber reinforced thermoset composite material layer has glass fibers in a vinyl ester matrix. The second fiber reinforced thermoset composite material layer is disposed over the first composite material layer and has carbon fibers in an epoxy matrix. The flex core layer is disposed over the second composite material layer. The third fiber reinforced thermoset composite material layer is disposed over the flex core layer and has aramid fibers in a vinyl ester matrix. The fourth fiber reinforced thermoset composite material layer is disposed over the third composite material layer and has glass fibers in a vinyl ester matrix.

Boom utilizing composite material construction

The present invention is a boom system comprising a first boom section having a distal end and a proximal end. A second boom section includes a distal end and a proximal end, wherein the proximal end of the second boom section is rotatably coupled to the distal end of the first boom section. At least one of the boom sections is substantially formed from composite materials.

A support apparatus used with construction masts. The support apparatus comprises a truss and a top adjustable mount assembly secured to the truss. The top adjustable mount assembly is selectively positionable so as to engage the construction mast.

Universal mast support frame and method for mounting masts

A fire fighting vehicle having a boom system includes a working assembly attached to an end portion of the boom system. The working assembly comprises a frame pivotally mounted at a midpoint of the frame to the end portion of the boom. The frame carries a mechanical actuator that is connected to a tool capable of piercing an exterior of a structure when the mechanical actuator is actuated.

Self leveling boom system with rotatable working assembly

An improved fire-fighting device designed to allow variable positioning of a quenching agent dispensing point. The fire-fighting device also allows high quenching agent flow rates. The device uses an articulable boom arrangement and solid pipeline to achieve these advantages.

Fire-fighting system having improved flow

The present invention is a boom system comprising a plurality of articulated boom sections. Each boom section has a longitudinal axis. A stiffening layer is attached to a surface of at least one of the boom sections, and extends within about ten degrees of parallel to the longitudinal axis of the boom section. The stiffening layer is formed of a fiber-reinforced composite material including a plurality of fibers and matrix material.

Boom stiffening system

The present invention is a concrete piping system comprising a pipeline. The pipeline includes an intake end, an output end, a liner resistant to concrete abrasion and a pressure tube of composite materials placed over the liner. A concrete pump is connected to the intake end of the pipeline.

Composite material piping system

The invention is a placing boom comprising a plurality of boom sections connected together in an articulated arrangement. A pipeline is carried by the boom sections, wherein the pipeline is disposed inside at least one of the boom sections.
