Abstract: A telescopic boom-mounted concrete pump is provided wherein a telescoping boom assembly is pivotally and rotatably mounted on the platform of the truck. The boom assembly includes inner, intermediate and outer boom members. A first concrete conduit which is in fluid communication with a source of pressurized concrete is mounted at one side of the inner boom member for movement therewith. A normally U-shaped flexible concrete hose has its inlet end thereof connected to the discharge end of the first concrete conduit. A rigid concrete conduit has its inlet end connected to the discharge end of the flexible concrete hose. A jib boom member in the form of a concrete discharge conduit is pivotally and rotatably connected to the outer end of the outer boom member and is in fluid communication with the rigid concrete conduit. The jib boom member is secured to and is positioned within a lattice truss. A winch is selectively removably secured to the outer end of the lattice truss.

The jib boom member may be removed from the outer end of the outer boom member and replaced with an aerial platform. A winch and sleeve is also mounted on the boom assembly.

Abstract: An apparatus is described for deicing an aircraft in one pass of the aircraft through the apparatus with the apparatus including a pair of spaced-apart deicing devices. Each of the deicing devices comprises a vertically disposed support tower having an upstanding boom pedestal rotatably mounted on the upper end thereof. An elongated, telescopic boom assembly is pivotally mounted on the pedestal for selective extension and retraction with respect thereto. An elongated support is pivotally mounted on the outer end of the boom assembly and has an operator's cab selectively movably mounted thereon. Spray nozzles are mounted on the operator's cab to enable the operator to spray deicing fluid onto the aircraft.

Abstract: An aerial lift comprising a self-propelled vehicle such as a truck or the like having a rotatable pedestal mounted thereon. An elongated telescopic boom has one end pivotally secured, about a horizontal axis, to the pedestal. A first support is pivotally secured, about a horizontal axis, to the upper end of the telescopic boom and has a second support pivotally secured thereto, about a vertical axis, to the outer end thereof. The second support has a first connector at its outer end which is adapted to be removably connected to a second connector element provided on a work station. The connector elements cooperate to mount the work station on the upper end of the telescopic boom and which may be disconnected to remove the work station from the telescopic boom.
