Alligator Grab Wireline Fishing Tool

Introduction

The alligator grab is a tool used to fishing from tubing. In most cases, it only use when other fishing tools cannot be salvaged.

General Technical Parameters

Structural features

Alligator grab consists of fishing neck, mandrel, adjusting nut, spring, skirts, shaft pin, claw, cylindrical pin and shear pin

(or pin and an auxiliary spring) etc., the specific structure is shown in the accompanying drawings.

When the skirt is moved up and down, the claws mounted on it can slide along the cylindrical pin on the mandrel and rotate around the pin to complete the opening and closing action; the shear pin (or pin) make the mandrel and the skirt to hold the claw keep it with open position; adjust the adjustment nut to compress the spring can get different clamping forces. When the shear pin is cut down (or release the tool string and release the pin), the skirt is moved down under the force of the spring, so that the claws are quickly closed and the well is clamped to drop the fish.

 Method

1. Connect the Alligator grab to the tool string.

2. Loosen the adjusting nut.

3. Install the shear pin (or use a thin iron rod to push it from the end of the pin into the skirt hole and hang it).

4. Adjust the adjusting nut and compress the spring to the proper position.

Note: The compression distance of the spring must be greater than the expected downward stroke of the skirt, otherwise the claws will not fall tightly.

5. Run the tool; shake down to cut the shear pin after reaching the position, (or releas the tool string to release the pin);

6. Lift the tool upwards; if the tool is blocked, please shake it up to the ground.

Note: When assembling and running the tool, if the alligator grab in the open position, no part of the operator's body should be below its spring to prevent the crocodile clip from cutting the shear pin accidentally (or releasing the pin) and pinching it.

 Maintenance

Ater use, please remove greasy dirt, debris, and sand debris in time to prevent the tool from being blocked .
