A base support assembly includes a substantially vertical first support brace; a substantially vertical second support brace oriented substantially parallel to the first support brace; and a first cross member and a second cross member each extending between the first support brace and the second support brace, the first cross member crossing the second cross member to define an X-shaped cross member assembly; wherein: each of the first and second cross members are coupled to the first support brace by a first brace tensioning knob and coupled to the second support brace by a second brace tensioning knob; and each of the first brace tensioning knobs and second brace tensioning knobs are rotatable to tension the first and second cross members with the first support brace and the second support brace.

A fire apparatus includes a chassis, a body assembly coupled to the chassis, a front cabin coupled to a front end of the chassis forward of the body assembly, a front axle coupled to the front end of the chassis, at least one rear axle coupled to a rear end of the chassis, and a ladder assembly including at least one extensible ladder section. The ladder assembly has a proximal end that is coupled to the chassis rearward of the front cabin and between the front axle and the at least one rear axle. The ladder assembly is operable through a sweep angle greater than fifteen degrees while at a depression angle greater than eight degrees.

A fire apparatus includes a chassis, axles coupled to the chassis, a turntable rotatably coupled to the chassis, and an aerial ladder assembly pivotably coupled the turntable. The aerial ladder assembly includes a first ladder section extending longitudinally, a second ladder section extending longitudinally, and a support slidably coupling the second ladder section to the first ladder section such that the first ladder section supports the second ladder section. The support facilitates longitudinal movement of the second ladder section relative to the first ladder section between an extended position and a retracted position. The support is pivotably coupled to the first ladder section.

Systems are provided for storing and retrieving objects such as ladders. The systems can include a carriage having a table that rotates, and a trolley mounted on the carriage for holding the object and moving the object linearly in relation to the carriage, so that the object can be stowed in locations such as on the roof of a fire engine or other emergency vehicle, or the roof of a stationary structure. The systems include features for locking the table and the trolley to increase the safety and efficiency of the loading and unloading processes.

A pop-up camper has a roof that is movable between a stored position where it is close to a perimeter wall and use position where it is raised away from the perimeter wall. The perimeter wall has a gap that receives a door that is attached to the pop-up camper at the floor level. The door pivots between a stored position where panel spans and seals a gap in the sidewall and use position where the panel folds down and a terminal edge is close to the ground. The door includes stringers with steps that extend between. Adjustable feet are received at the end of the stringers adjacent the terminal edge and telescopically slide between a stored position where the feet are locked from rotation and do not extend beyond the terminal edge and an extended position where the feet can pivot.

An electronic display for an aerial device is provided. The electronic display replaces a traditional load chart including the operational parameters of the aerial device being used. The electronic display electrically connected with a computer control system connected to a sensor for collecting at least one piece of data relating to the operational parameters of the aerial device. The computer control system calculating the current operational parameter of the aerial device based on the at least one piece of data collected by the sensor and updating the operational parameters of the aerial device and displaying a graphical representation of the updated operational parameters on the electronic display.

A climbing apparatus for safely climbing on a roof of a trailer, the climbing apparatus comprising a ladder portion, a upper pivot portion for pivoting an upper portion of the ladder portion, the upper pivot portion being secured to the trailer to allow movements of the ladder portion between a work configuration and a stored configuration next to a wall of the trailer and a movable support adapted to maintain the ladder portion in the work configuration by providing increased angle between the ladder portion and the wall of the trailer.

This disclosure pertains to industrial trucks, and in particular to aerial-ladder trucks with bed extensions. An aerial-ladder truck consistent with the present disclosure includes a cab at a front thereof and a truck bed at a rear thereof. The back end portion of the truck bed includes bed extensions that are slidably coupled in a transverse direction to the back end portion of the truck bed. When the bed extensions are engaged, the width of the truck bed increases by a length that the bed extensions extend from the truck bed. The aerial-ladder truck further includes a ladder turret provided to the truck bed to pass there through. The aerial-ladder truck further includes an extensible post fixedly passing through the ladder turret, an extensible ladder connected to a top portion of the extensible post, and a carrier provided at the top thereof.
