A multi-function ladder having a front section having a first front rail and a rear section. The ladder having a first hinge attached to the first front rail and the first rear rail. The ladder having a second hinge attached to the second front rail and the second rear rail. Each hinge having a locked state and an unlocked state. The ladder having an actuator directly attached to the front section and remote and separate and apart from the first hinge and the second hinge. When the first and second hinges are in the unlocked state, the rear section can be moved between a leaning ladder mode, a step ladder mode, a stairway ladder mode and a straight ladder mode upon which each hinge goes into the locked state in the desired ladder mode.

A ladder that facilitates a contraction of handrails is provided. The ladder includes a front tube and a rear tube hinged to each other; an armrest frame sleeved on the front tube, a vertical rod of the armrest frame is inserted into the front tube and slides in cooperation with it; an elastic locking member that cooperates with the vertical rod, the elastic locking member can expand and contract elastically in a radial direction of the vertical rod, thereby achieving fixation or unlocking between the front tube and the vertical rod; an unlocking member provided on the front or rear tube; when the front tube and rear tube are folded, the unlocking member acts on the elastic locking member, the elastic locking member is caused to release a locking state of the front tube and the vertical rod, thereby achieving automatic contraction of the armrest frame.

Fall restraint equipment comprising a mobile access unit having a mobile platform portion, a ladder portion, and a cage portion. The components of the fall restraint equipment are formed from butterflying, lasering, cutting, bending, and/or stamping continuous pieces of tubular and sheet metal. The components of the mobile access unit are modular and include adapters of varying height that cause the mobile access unit to exhibit varying height. Also, the mobile access unit is adaptable so that it can roll in a first direction of orientation of the ladder or a second direction perpendicular to the first direction.

A single handrail telescopic ladder is provided. Which includes front tubes and rear tubes that are hinged to each other at a top; a single handrail tube that is scalability inserted into one of the front tubes; the front tubes are provided with a fixing hole, and a locking hole corresponding to the fixing hole is provided at a corresponding position of the single handrail tube; locking members pass through the fixing hole and the locking hole when the single handrail tube is pulled out from the front tubes to a predetermined position; and an elastic member that directly or indirectly acts on the locking members and provides a pre-tension force for the locking member; when the locking members are unlocked, the locking members exit from the fixing hole and/or locking hole, allowing the single handrail tube to automatically retract into the front tubes.
