Soil compression augers are not designed to dig and remove dirt. They are intended to compress the soil as the flightings (spirals) penetrate the soil and compress it to a greater strength than it was originally. In order for this to take place, there needs to be a certain amount of moisture in the soil to pack the dirt tighter. Level 7 moisture content is preferred but more or less can be effective and ultimately achieve the “soil compression” ratio.
AUGER ANCHOR ROPE RESCUE KIT
Installation instructions and tips:
Inside the fuselage of the auger is a ¾ inch square drive. The installation tool for this is a ¾ inch square drive ratchet and extension. (Figs. 1, 2, 3). Be sure to remove the cap before installing so as not to damage the threads during installation.
Once the tool is properly installed in the auger anchor, the auger is ready to install. Putting downward pressure while rotating the auger clockwise allows the “flightings” to begin digging into the soil (Fig. 4). Within the first rotation of the flightings (Fig. 5) or as soon as enough dirt covers the flighting blades, the auger should begin to penetrate deeper without the help of downward thrust or pressure. Rotate the auger into the ground until the dirt is just below the first or lowest ring of the threads of the cap. At this point the auger is considered to be at “grade” (Fig. 6). Should you feel that you need still greater support you and can make use of attachments such as couplings to penetrate “below” grade to the depth desired.
If the dirt you’re trying to auger into seems too hard or too thin for the flightings to grab into, a simple remedy is to introduce a small amount of water at the penetration point, wait a few minutes and then try again. Repeat this process until the auger rotation is sufficient to penetrate the soil by itself.
In order for the auger to be installed properly, torque, or the amount of pressure resistance needed to rotate the auger into the ground, is an important aspect of the procedure. The greater the torque needed to install the anchor, the stronger its holding capacity. The most appreciable torque range is from 250 foot pounds to over 1700 foot pounds. The type of soil composition and moisture content will ultimately dictate the soil type and torque expected. Ability to recognize and install accordingly will determine how many anchors will be needed for the rescue.
If the soil is so soft that you have little to no resistance while rotating the auger into the ground, it is strongly suggested that a second anchor be installed to add a support and that the two be attached to each other with a “webbing strap”. Should the second auger also be easy to install in what might be considered soft dirt, then a third would be suggested for the safest holding power.
When the first auger anchor has been secured as necessary by one or two backup anchors, it can be rigged with webbing straps and appropriate rope attachments (Fig. 7, 7a, 7b). Only electrical conduit unions will thread onto the fuselage (Fig. 8).
An 1800 foot pound version is recommended if you are using a 3/8 inch hose and a SCBA adaptation. Always check your torque resistance in the soil with the hand tool before securing rope attachments. We discourage using electrical impact guns or core drills. They simply do not generate sufficient torque to install properly.
These instructions are the recommended procedures for installing and precautions for use. Caution and reasonable adaptation is expected within the limits and capabilities of this product for intended use applications.
Auger anchors are only effective in soil. They cannot penetrate solid rock or ice. Attempting to use in compositions other than soil could result in auger anchor failure. Check auger assembly for damage after every installation and discard auger if damage is found. (Examples: damaged threads in cap area, broken or damaged flightings.)
Using this auger in rescue maneuvers can result in injury, critical injury, and possibly death due to improper installation or failure to understand critical issues of installation. Failing to back up or attach connecting assemblies to the auger assembly properly can compromise holding strength and increase the likelihood of product failure.
