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 first and a second position. When tension is applied to the rope, the spring mechanism allows upwards or downwards movement of the fly section relative to the base section. When tension is removed from the rope, the spring mechanism slows or resists upwards or downwards movement of the fly section relative to the base section regardless of the fly section's position relative to the base section.

A vehicle includes a chassis defining a longitudinal axis, a cab coupled to the chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, a body assembly coupled to the chassis, and an implement. The body assembly defines a recess that includes a plurality of angled portions. The plurality of angled portions extend laterally outward at a downward angle away from the longitudinal axis. The implement has a proximal end disposed within the recess. The plurality of angled portions at least partially facilitate the implement in traveling through at least one of a sweep angle range or a depression angle range.

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 shelf apparatus configured for temporary attachment to a ladder deployed in a working position includes a planar tray supported at its inboard end by a rung or top plate of the ladder, left and right support arms pivotably attached to opposite sides of the tray near its inboard end, a rigid linkage coupling the tray to the left and right support arms, and an adjustable clamping mechanism for clamping the tray to the rung or top plate. In use with a straight ladder, the tray is horizontally suspended under the inclined frame of the deployed ladder, the support arms are raised to rest against the inclined rails of the ladder above the tray, the rigid linkage vertically supports the tray from the support arms, and the clamping mechanism secures the tray to the rung.
