Rigid arms mounted to dual bridge cranes provide a solid end effector support with limited degrees of freedom. The end effector holds product at predetermined angles set to match the orientation of fixtures and shipping containers.
A rigid crane is a combination of a bridge crane with a rigid mast supporting an end effector. The rigid mast moves along the bridges with a 4 trolley carriage and has 360° rotation. The end effector rides up and down the mast on a vertical carriage with linear slides. It is hoisted by a dampened air cylinder, an air over oil cylinder or an air balancer.
Compared to traditional balancer supported end effectors, rigid arms are heavier and slower, providing smooth and predictable movement. Limited X, Y, and Z motions and a single rotation eliminates an operator’s concern regarding the orientation of the product.
Rigid arm use is limited to applications where conventional end effectors are insufficient in controlling the approach angle of the product.

Articulating arm cranes are similar to jib cranes with an additional joint (elbow), which makes the crane easier to move and repeatably position an object. Features Articulating arms [...]
Jib cranes are ergonomic systems having a horizontal enclosed track or open beam member, which supports a movable hoist. They are fixed to the floor with a single mast or mounted to a wall. [...]
Enclosed Track Cranes
Enclosed track cranes are simple and effective ergonomic systems designed to increase productivity, quality and improve worker safety. Bridges travel along a set of runways, which are commonly supported by a gantry style structure. [...]
