Delta-T Access tube extraction kit

The PR-EXK1 Extraction Kit is a robust, field-ready system designed for the safe and efficient removal of installed access tubes used with PR2 Profile Probes and similar soil moisture monitoring systems. Built to handle the substantial forces required in dense or compacted soils, the kit ensures that access tubes can be extracted without damage to equipment or risk to surrounding installations.

Key Components

• Hi-Lift Jack – A heavy-duty cast iron jack, supplied in a carrying bag, capable of generating the large lifting forces needed to free access tubes from soil.
• Jack Foot – A folding aluminium base plate that spreads the load and provides stability on the ground during extraction.
• Tube Clamp – A silver-and-black clamp with a lever bar, designed to grip the top of access tubes securely and prevent slippage during lifting.
• Chains & Lifting Assembly – Heavy-duty chains and hooks for connecting the jack mechanism to the tube clamp and applying upward force.

Key Features

• High-Force Extraction – Engineered to cope with the significant resistance often encountered when removing deeply installed access tubes.
• Safe & Secure Grip – Lever-activated clamp ensures firm attachment to access tubes.
• Stable Operation – Jack foot provides a broad, steady base to prevent tilting or instability during use.
• Portable Field Kit – Supplied with bag and components for ease of transport to field sites.

Applications

• Removal of access tubes after completion of soil moisture monitoring campaigns.
• Redeployment of PR2 Profile Probes to new locations.
• Field studies in agriculture, irrigation management, and environmental monitoring requiring repeated relocation of tubes.

Safety Instructions

• Heavy Equipment Caution – The jack is cast iron and heavy; it must be handled carefully.
• Clamp Tightening – Ensure the tube clamp is tightened securely (with the lever bar if necessary) to prevent slipping under load.
• Jack Handling – Always support the jack’s lifting arm before releasing or operating the reversing latch, as the arm can fall suddenly.
• Force Requirements – Be prepared for high resistance; use gradual, steady jacking motion rather than sudden force.

Extraction Procedure

1. Position the jack foot around the access tube.
2. Place and tighten the tube clamp securely on the top of the access tube.
3. Attach the lifting chain hooks to the clamp’s ring bolt.
4. Insert the jack into the jack foot and engage the lifting arm.
5. Pump the jack lever until the access tube is extracted or loosened enough to remove manually.
6. Always support the lifting arm before disengaging the jack latch to release pressure.

The PR-EXK1 Extraction Kit is a reliable solution for field researchers needing to remove access tubes from soil with precision and safety. Combining a heavy-duty jack, stabilising foot, and secure clamp, the kit ensures efficient tube extraction across a range of soil types, making it an essential accessory for soil moisture monitoring programs.
