Abstract: The present invention relates to an apparatus and a method to repair the interior of a vertical structure. The invention includes a telescopic ladder and a knockdown platform that can be deployed and assembled on-site.

Abstract: The present invention relates to a utility vehicle, in particular to a firefighting vehicle, including an aerial apparatus (i.e. a turnable ladder and/or an aerial rescue platform) and lateral ground supports movable between retracted positions and extracted operating positions in which the ends of the supports rest on the ground. The vehicle includes a monitoring system for monitoring the position of the vehicle. The system includes surveillance cameras at the sides of the vehicle, each camera being allocated to one support to monitor the ground area on which the end of this support rests in its operating position and to take a real-time image of the respective ground area. The system also includes a visual display presenting the images of all cameras at the same time in different screen areas, superposed by visual markings representing expected operating positions of the supports.

Abstract: A quint configuration fire apparatus includes a chassis defining a longitudinal direction, a body assembly coupled to the chassis and having a storage area configured to receive a ground ladder and a fire hose, a pump coupled to the chassis, a water tank coupled to the chassis, a ladder assembly including a plurality of extensible ladder sections, the ladder assembly coupled to the chassis with a pedestal and a torque box, a single front axle coupled to a front end of the chassis, and a single rear axle coupled to a rear end of the chassis. The ladder assembly is extensible to provide a horizontal reach of at least 100 feet and a vertical height of at least 105 feet. The torque box extends along the longitudinal direction and spans the single rear axle thereby transferring loading along the chassis.

Abstract: A ladder system is provided. The system includes an extendable ladder and a ladder safety device. The extendable ladder includes at least a first section and a second section. The ladder safety device includes a first guide rail secured to the first section, a second guide rail secured to the second section, an a guide rail intersection portion that merges the first guide rail into the second guide rail at a point of intersection. The guide rail intersection portion allows the first guide rail to slide with respect to the second guide rail such that the point of intersection changes as the second section extends or retracts with respect to the first section.

Abstract: The present invention refers to a turntable ladder system (18), comprising a turntable ladder (20) mounted on top of a rescue vehicle (10) and comprising an arm (24) that can be bent downwardly to the ground (28) in front of the driver's cabin (12) of the vehicle (10), and an operator stand (32, 40) located at the ladder (20) for operating the ladder (20), said operator stand (32, 40) comprising control means (34, 42) for controlling a movement of the arm (24). This turntable ladder system is characterized by manually operable confirmation means (36) located at the front of or laterally at the driver's cabin (12), said confirmation means (36) being operatively connected to the control means (34, 42) such that the bending movement of the arm (24) can be controlled by the control means (34, 42) only in case the confirmation means (36) are operated.

Abstract: A ladder safety device, systems and methods of arresting falls from ladders are provided. The ladder safety device includes a safety guide that extends along the length of an extension ladder. The length of the guide along the length of the ladder extends and contracts in unison with the extension and retraction of the extension ladder, and a tension is maintained on the guide to maintain a load during use of the ladder for climbing.

Abstract: A collapsible access tower has a chassis 10 supporting a pair of road wheels 11 and outriggers 16,17 to impart stability when in use, and a pair of extensible multi-section columns 26,50 carrying a platform 35. A section 27 of one column 26 is rigidly connected to the chassis and another section 33 of that column to the platform 35. The other column is configured as an extendible ladder 50 one section 51 of which is hinged to the chassis 10 and another section 52 of which is hinged to the platform 35. When the platform is in its lowermost setting, the hinged connections of the two sections 51,52 of the ladder 50 are co-axial so that the ladder may be pivoted to a transit setting. A winch arrangement 39 is associated with column 26 to allow raising and lowering of the platform 35.

Abstract: A roof venting apparatus is mounted to a firefighting vehicle's aerial extension ladder, where a semi-cylindrical, double-pointed lance is dropped and raised onto and through the roof of a burning structure as many times as necessary to properly vent the burning building. The lance is dropped and raised by a free-spooling, electric braking winch, which is mounted to an anchor board securely hooked onto the bottom rungs of a fire truck's aerial extension ladder, and which is operated by a fire fighter on the ground who mans a toggle control panel welded onto the lower anchor board. The winch cable extends up the length of the extended aerial ladder, through a series of stabilizing, free-wheeling idler wheels mounted to another removable anchor board screwed onto the top rungs of the truck's extension ladder. The lance, if hollow, is transported to the scene of the fire empty, where it can be filled with water with the fire hose, to establish the necessary dropping weight.
