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 mobile large manipulator includes a chassis, unfoldable and/or extendable working boom, supporting struts, vertically extendable supporting legs, and a micro-controller-based program-controlled supporting aid. The unfoldable and/or extendable working boom is arranged rotatably around a vertical axis on the chassis. The supporting struts are respectively arranged on the chassis and are horizontally extendable from a travel position to a supporting position. The vertically extendable supporting legs are arranged on respective outer ends of the supporting struts. The supporting legs support the mobile large manipulator via respective supporting forces of the supporting legs. The supporting aid is configured to determine supporting forces for the respective supporting legs based, at least in part, on the supporting position of the supporting struts in which the chassis of the large manipulator is deployed unstressed in a support state.

Maneuverable ergonomic trailer stands are disclosed. An example portable trailer stand includes a frame having an upper ledge; an extendible leg coupled to the frame, the upper ledge being vertically movable to selectively engage and disengage an underside of a trailer parked on a driveway based on movement of the extendible leg relative to the frame; a wheel connected to the frame, the wheel to remain at a substantially fixed distance from the upper ledge as the upper ledge is vertically moved

A turntable leveling system is configured to level a boom turret of an aerial device. This allows the boom turret to be leveled more than with level correction by outriggers. The turntable leveling system includes a lower turntable wedge and an upper turntable wedge. Each of the lower turntable wedge and the upper turntable wedge is independently rotatable relative to the chassis. The turntable leveling system is configured to be installed between a chassis and the boom turret of an aerial device. The turntable leveling system may further comprise a central turntable wedge disposed between the upper turntable wedge and the lower turntable wedge.
