1. Key Design Features of Folding Arm Crane
Articulated Boom: Consists of two or more sections connected by a pivot point. This allows the crane to “reach over” a wall or “tuck into” a low-ceiling doorway.
Compact Stowage: When not in use, the arm folds back on itself into a small, vertical package. This is critical for truck-mounted versions, as it leaves the entire flatbed free for cargo.
360° Rotation: Most folding arm cranes can rotate a full circle, allowing for a massive “work envelope” without needing to move the base or vehicle.
2. Integration with “Zero-Gravity” Technology
In modern workshops, the folding arm crane is often paired with intelligent hoisting or pneumatic balancing to create a “Smart Folding Jib.”
Weightless Maneuvering: In this configuration, the folding arm provides the reach and the zero-gravity hoist provides the weightlessness.
Manual Guidance: The operator can grab the load directly and “walk” it through a complex path, with the folding arm pivoting effortlessly to follow the human’s movement.
3.Common Industrial Applications
Marine & Offshore: Loading cargo from a dock onto a boat where the crane must reach “down and under” the deck.
Urban Construction: Delivering materials to the second or third floor of a building through a window or over a fence.
Workshops & Machine Shops: Servicing multiple CNC machines with a single wall-mounted folding arm that can navigate around support pillars and other equipment.
4.Safety Advantages
Because folding arm cranes allow the operator to place the load precisely where it needs to go (rather than dropping it from a distance and swinging it into place), they significantly reduce the risk of:
