A vehicle includes a chassis, tractive assemblies, a body assembly, a turntable, a platform, and a control console. The tractive assemblies, body assembly, and turntable are coupled to the chassis. The platform supports an operator in a command position and includes an outer perimeter. The control console includes a base coupled to the turntable and spaced from the outer perimeter. The control console includes a movable section that is movably coupled to the base and includes an operator interface configured to receive operator commands to control a vehicle system. The movable section is repositionable relative to the base between a stowed position and an operating position. The operator interface is accessible by the operator from the command position when the movable section is in the operating position. The vehicle has an overall height defining a top plane. The movable section is below the top plane when in the stowed position.

A modular staircase is disclosed. The modular staircase includes a first staircase section having a plurality of steps and a first support member detachably connected to the first staircase section. Further, the modular staircase includes a second stair module having a second staircase section including a plurality of steps and a second support member detachably connected to the second staircase section and to the first support member. The modular staircase further includes a third stair module having a third staircase section including a plurality of steps and a retractable third support member detachably connected to the third staircase section and to the second support member. The third support member may be configured to raise or lower the third staircase section relative to the second staircase section.

A pair of right and left supporting bases (10) provided on a sidewalk (9) of a revolving body (4) and both right and left sides (16) of a movable ladder (12) are connected by trajectory restricting members (22) in a swingable manner. In positions of the left supporting base (10) which are apart from each other, main body base ends (20a and 21a) of first and second hydraulic cylinders (20 and 21) are pivotally supported, and rod tip ends (20b and 21b) of the respective hydraulic cylinders (20 and 21) are pivotally supported in a common position of the left side (16) of the movable ladder (12). By operating the first and second hydraulic cylinders (20 and 21) in directions reverse to each other (extension and retraction), in-common pivotally supported parts (20b and 21b) are moved, thereby switching a position of the movable ladder (12) between an extended position and a retracted position.

A vehicle includes a turntable rotatably coupled to a chassis, a platform coupled to the turntable, and a railing coupled to the platform. A control console includes a base section coupled to the turntable and spaced from the railing and a movable section that is movably coupled to the base section. An access opening is defined between the railing and the base section. The platform is accessible by an operator through the access opening. The movable section of the control console is selectively repositionable relative to the base section between a stowed position and an operating position. An operator interface of the movable section is configured to be accessed by the operator when the movable section is in the operating position. The movable section of the control console extends across the access opening when in the operating position, thereby limiting operator accessibility through the access opening.

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.

An emergency descent system includes at least one ladder which is articulated on at least one supporting unit on a bearing device. The ladder is designed to be unfolded about this bearing device out of a rest position in which the ladder is disposed parallel to the at least one supporting unit and into a working position, wherein a push-out unit and a pivot unit operatively connected thereto by means of a catch are associated with the ladder. The pivot unit drives the push-out unit by the kinetic energy generated during the unfolding, wherein the push-out unit moves away from the at least one supporting unit at a first acute angle, and in the operating position, the push-out unit forms an acute angle with the at least one supporting unit and the pivot unit is held at an obtuse angle relative to the push-out unit on a stop associated with the at least one supporting unit.
