摘要： Provided is a braking system for use with an extension ladder having a base section and a fly section movable relative to the base section via an adjustment rope. The braking system includes a bracket for attachment to the fly section. A pulley and an arm are secured to and movable relative to the bracket by the adjustment rope between a first position when no tension is applied to the rope and a second position when tension is applied to the adjustment rope. A cam is movable between an engaged position when the pulley and arm are in the first position with the cam engaging with the base section to prevent movement of the fly section relative to the base section, and a disengaged position when the pulley and arm are in the second position.

摘要： A ladder is described. The ladder includes a plurality of rungs. A heating element is coupled to at least one rung of the plurality of rungs. A power supply provides current to the heating element to generate heat. A portion of the heat is transferred to the at least one rung. The heating element can be located at least partially inside the rung. The power supply can be located remotely from the ladder.

摘要： A quint configuration fire apparatus includes a chassis, a pump and a water tank coupled to the chassis, a body assembly coupled to the chassis, a single rear axle coupled to a rear end of the chassis, and a ladder assembly having an end that is coupled to the chassis. The ladder assembly includes a first section, a second section, a third section, and a fourth section, a pad slidably coupling the first section to the second section, the pad defining a first engagement surface and a second engagement surface, and a resilient member coupling the pad to a bracket. The first engagement surface is spaced an offset distance from the second engagement surface. The bracket is positioned to support the pad such that the first engagement surface and the second engagement surface contact the second section and transfer loading along the ladder assembly.

摘要： A cover is provided to protect steps leading to a cab of a vehicle from accumulation of mud, snow, ice and other debris when the vehicle is driven. The cover is pivotally mounted for movement between an open position allowing a vehicle operator to climb the steps and a closed position covering the steps from top to bottom to maintain cleanliness of the steps as the vehicle is driven. The cover can be opened and closed from the top of the steps, either manually or with an actuator. The cover is normally closed when the vehicle is moving and open when the vehicle is stationary.

摘要： A ladder set for rescue vehicles, including a base mounted on a vehicle, an end part and connecting parts disposed therebetween. A traction device is mounted for an extension cable and a roller arrangement for guiding the cable. Roller pairs are mounted on connecting parts, of which each include a front roller and a rear roller. A deflecting roller is located on the end of base part pointing in the direction of extension, via which extension cable is guided in the direction of the traction device. Extension cable is secured to end part by its end opposite traction device and is guided from fixation point to deflecting roller then via roller pairs of connecting parts in their connecting order, in such a way that extension cable first passes the first and then the rear rollers of a roller pair.

摘要： The present invention is related to a control system for controlling the movement of an aerial apparatus, in particular for controlling a turnable ladder of a firefighting vehicle, comprising a manually operable input device that is deflectable in at least one spatial direction by a deflecting force, an processing unit for converting the amount of deflection of the input device into a corresponding speed signal and an actuating unit for moving the aerial apparatus with a speed corresponding to the speed signal. The invention is characterized by determining means for determining a possible maximum speed and restricting means for counteracting or limiting the deflection of the input device according to the determined possible maximum speed.
