Retrieval operations, whether in the general manufacturing, aerospace/aviation, automotive, or power generation industry, often involve navigating through complex and often inaccessible locations to remove foreign object debris (FOD). This is where retrieval tools, with their unique designs and practical uses, come into the picture.
Watch how to use various retrieval tool jaw sets in various FOD removal applications.
Purposes of Retrieval Tool Jaws
The main Retrieval tools are specifically designed to capture and remove FOD that might hinder operations or pose a potential risk if left unchecked. They come particularly handy in environments where human access could prove challenging, dangerous, or even impossible. These tools, in combination with remote visual inspection (RVI) equipment like video borescopes, provide remote access solutions that help you safely and efficiently manage your FOD challenges.
The Diversity in Design
Retrieval tool jaws vary significantly in design, each one capable of handling different types of FOD in different types of FOD removal applications.
Three-Prong Gripper

The old stalwart, Three-Prong Retrieval Tools are ideal for picking up a wide range of items, from small machine parts to larger, more unwieldy objects. Their adjustable prongs can grip around objects from almost any angle.
Snare Loop

Due to its design and functionality, the Snare Retrieval Tool is particularly adept at securely retrieving round, elongated, or irregularly shaped objects that other tools might struggle to handle. These could include parts such as lost bolts, oddly shaped shards, or cylindrical objects that have found their way into inaccessible areas.
Alligator Jaw

Characterized by its alligator-like clamping mechanism, the Alligator Jaw Retrieval Tool allows for a secure grip and enhanced control over the captured FOD. Similar to the Long Tooth Jaw Retrieval Tool and the Gripping Plier Retrieval Tool, these tools offer an exceptional method of retrieval for objects requiring strong grip strength and exceptional control, such as objects that are amidst other fixtures or lodged within complex machinery.
Cup Forceps

The Cup Forceps Retrieval Tool is a versatile and effective solution tailored specifically for recovering a variety Foreign Object Debris (FOD). The tool's stellar capabilities are showcased when extracting round, smooth, or delicate objects that often pose challenges for other retrieval tools. Its cup-like design allows it to gently encompass and securely hold spherical or bulbous objects, such as loose bearings, pebbles, marbles, or other similar forms of FOD.
