A hang ladder is removably mounted to a trailer by a pair of mounting brackets that are attached to the ladder's side rails. The mounting brackets have a body and an arm with a fixed width slot extending between their upper sections and with a flared end at the open end of the slot. The slot is skewed relative to the longitudinal base of the bracket, and the rub rail of a flatbed trailer fits within the slot so that the ladder is secured to the rub rail on the side of the trailer. A tapered end of the arm can produce the flare in the end of the slot.

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 folding staircase for use in a door opening having a threshold. The folding staircase has a pair of stringers that have an upper end and a lower end that is adapted for contacting a ground surface. The stringers are spanned by at least one tread. A hinge is connected to a floor near the door opening and a threshold plate pivotally connected thereto is movable between a use position and a stowed position. The staircase may be provided with a lifting mechanism that biases the staircase and threshold plate toward their stowed positions. The lifting device provides a variable force that provides more rotational force when the staircase would require a user to bear more of its weight and less force when less of the weight of the staircase would be borne by a user.

A system is provided for interconnecting a ladder to a vehicle. The system may include a first portion for interconnecting to an upper portion of a vehicle rear door and a second portion for interconnecting to a lower portion of the vehicle rear door. The system provides a ladder interconnection wherein no penetrations are made into the vehicle.

A roof rack side ladder system is provided with a ladder assembly, a roof rack mounting assembly, and a bumper bracket. The roof rack mounting assembly attaches the upper ladder portion of the ladder assembly to the roof rack of a vehicle and provides for a dual pivot attachment of the ladder assembly to the roof rack for absorbing suspension forces while the vehicle is in transit. The bumper bracket attaches the lower ladder portion of the ladder assembly to the side bumper wing of a vehicle.

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.

An access system (10) for an earth moving equipment (100) to allow a person to travel from ground level to an elevated position, said access system (10) includes an access means (12) mountable on to the earth moving equipment (100), and a retraction mechanism (50) to move the access means (10) between a deployed position (14) wherein a person can ascend or descend on the access means and a retracted position (16) wherein the access means (10) is stowed, and a locking means (52) moveable to an operative position wherein the locking means (52) restrains movement of the access means (10) in the retracted position (16).
