Autonomous vehicles including ladders and related methods are disclosed. An example system includes an autonomous vehicle including an integrated ladder and a processor to detect a state of the ladder as being in one of a stowed state, a deployed state, or a use state; in response to detecting that the ladder is in the stowed state, cause the autonomous vehicle to operate in a first drive mode and a second drive mode; in response to detecting that the ladder is in the deployed state, cause the autonomous vehicle to operate in the second drive mode and to restrict from operating in the first drive mode; and in response to detecting that the ladder is in the use state, cause the autonomous vehicle to refrain from operating in the first drive mode and the second drive mode.

A convertible ramp system facilitates transfer of personnel between spaced elevations. The ramp system includes a deck assembly, a convertible main ramp, and a convertible extension ramp. The convertible main ramp has a proximal end hinged to the deck assembly and a distal end adapted for being mechanically lifted and lowered relative to the deck assembly. Both the main ramp and the extension ramp incorporates an adjustable frame assembly and a series of simultaneously articulating foot treads carried by the frame assembly. The ramps are selectively convertible between a stairway configuration and a substantially flat and continuous runway configuration.

A ladder system is cooperable with a surface such as a recreational vehicle rear wall or the like and includes a wall mount securable to the surface, a ladder with a plurality of rungs, a securing bracket connected to one of the plurality of rungs. The wall mount includes a flat back section engageable with the surface, an engagement portion connected to the flat back section, and first and second openings between the engagement portion and the flat back section, where the first and second openings are spaced from each other. The securing bracket of the ladder system includes a pair of grips that are sized to fit over the engagement portion of the wall mount in the first and second openings.

Systems are provided for storing and retrieving objects such as ladders. The systems can include a carriage, 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 can further include a handle assembly that permits a user to move the trolley while the user is standing on the ground. The handle system is configured to secure the trolley in a stowed position, and allows the user to release the carriage from its stowed position.

A ladder comprises a front leg and a rear leg connected by a slider bracket. The slider bracket comprises a base and a track. The base comprises an aperture therein. The track extends away from the base and comprises a slot therein. The base is rotatably coupled to the front leg by a front pin in the aperture. The track is slidably coupled to the rear leg by a rear pin in the slot. When spreading the rear leg away from the front leg, the base pivots around the front pin as the rear pin slides in the slot of the track until the rear pin reaches the end of the slot in the track. The slot also may include a latch at the end of the slot that engages the rear pin.
