How It Works
How the Emergency Tree Jack™ Works
The Emergency Tree Jack is a professional mechanical lifting tool designed to stabilize and lift fallen trees off structures in emergency or storm-damage situations. It gives crews the controlled lift they need when a tree is pinned, wedged, or resting against a structure helping create a safer working environment for cutting and removal.
Step 1: Perform a Safety Assessment
Before placing the jack, assess the scene for hazards. Confirm the tree is fully supported and at rest on the structure and not at risk of further movement or collapse during setup and operation of the jack including cranking and lifting. Confirm the rootball is attached, still partially rooted in the ground, and the trunk is not at risk of rolling or sideways movement. Do not use the Emergency Tree Jack on unstable trees that may fall or shift unexpectedly when operating the jack. Do not attempt to retrieve the jack if the tree is at risk of further movement or collapse. Allow the jack to fall with the tree and maintain a safe distance.
Step 2: Position the Jack at the Base of the Tree
Place the Emergency Tree Jack underneath the tree trunk where it's approximately 5'-8' above the ground. Raise the telescoping sections until just underneath the trunk and pin in place. The jack should sit on stable ground or a solid surface, aligned to provide controlled upward force without lateral movement.
Step 3: Secure the Jack Using a Chain or Rope
Use a high-strength chain or rated synthetic rope to secure the jack base to the tree trunk near the root ball using one or more of the provided attachment points. This step is safety-critical and helps prevent backward slippage during operation. Supplemental measures may include inserting ground pins through the base plate to anchor the jack firmly into the soil or surface.
Step 4: Operate the Jack to Raise or Stabilize the Tree
Once secured, begin lifting by operating the jack handle. Apply steady, controlled pressure until the tree lifts enough to relieve pinching, binding, or compression. This creates space for safer cutting, extraction, or additional rigging setups. Stop turning the handle when it begins to feel heavier and more resistance to turning. Continuing to crank could damage the jack's internal components.
What the Emergency Tree Jack Does
- Allows crews to work with more control in hazardous situations
- Removes risky variables
- Creates clearance to make safer cuts minimizing further damage to the structure
- Reduces risk of sudden movement or collapse
What It Does NOT Do
- It is not a full tree-removal machine
- It does not lift unsupported or free-hanging trees
- It does not replace safe cutting practices or trained operators
