grabber

A grabber is a device designed to seize and hold objects, typically via two handles or jaws that close around the item. Grabbers are used to extend reach, handle objects at a distance, or manipulate items in tight or hazardous environments. They can be operated manually or powered by pneumatic, hydraulic, or electric actuation.

Manual grabbers, often as long-handled litter pickers or tool claws, rely on a trigger or lever to close the jaws. Powered grabbers are common in industry and science; they use actuators that open and close the gripping fingers, sometimes with feedback controls for precision.

Grippers come in various geometries. Parallel-jaw and angular grippers provide stable, predictable clamping. Soft-grippers use compliant materials to reduce damage to delicate objects. Some grabbers incorporate vacuum cups, magnets, or wire fingers to accommodate unusual shapes or materials.

Applications include material handling in manufacturing and packaging, waste sorting and recycling, agricultural picking, mining and construction, search and rescue, laboratory sample handling, and medical or dental contexts where access is restricted or contact safety is needed.

Design considerations cover payload capacity, reach, opening width, actuation method, material compatibility, and maintenance. Operators must follow safety guidelines to avoid pinching injuries and ensure stable control, particularly when handling heavy or hot objects.
