Long ShapeArrays™ are shipped in specially constructed crates. These crates will require some site preparation, as they are difficult to move around and have special requirements for the crate’s Winch System. This should be done in advance of attempting the installation. A raised surface for the crate above the top of the borehole and casing will help to ensure a smooth installation experience. Many customers place the crate on a flat bed truck and park it next to the borehole as a support platform.
For applications where a weighted assembly is being used – a weighted assembly collar is offered for improved safety and efficiency of installation, particularly when used with the SAAV Cleat as described in these instructions. The weighted assembly collar also allows for the removal and anchoring of the ShapeArray™.
NOTE: Measurand highly recommends that users perform a complete diagnostics test on their ShapeArray™ prior to installation to ensure the instrument is working properly. The .TXT report file generated should be included with the installation log for record-keeping purposes. A complete diagnostic report from the time of installation could be required to advance warranty claims should an issue occur in the future.
The following table outlines the tools and equipment required to install.

Crated ShapeArray™ installations with a Weight Assembly generally follow the steps listed below. Each step is described in more detail in their own linked article.
- Unpack the ShapeArray™ Crate
- Prepare the Crate's Winch Assembly and Begin Installation
- Install Weight Assembly and Lower the ShapeArray™
- Setup the Tripod and Block and Tackle
- Settle the ShapeArray™ into the Casing and Verify Compression
Once the instrument has sufficient compression, the aircraft cable can be disconnected from the block and tackle. The slack aircraft cable should be looped together cleanly and tapped to the outside of the borehole casing. This cable will be required to retrieve the ShapeArray™ in the future and care must be taken to ensure it is not lost into the casing. Care must also be taken to reduce the risk of anything catching or pulling on cable as this will directly impact the ShapeArray™ and affect the data returned from the instrument.
The crate, winch, tripod, and block and tackle system should be kept in case the array needs to be recovered in the future or for future installations of arrays with weight assemblies.
The tripod and block and tackle system can be disassembled and returned to their shipping packages for storage.
The winch system can be respooled again by turning the nut on the winch clockwise. The winch’s cable can be detached from the reel’s rung with a 7/16” socket or wrench and secured to the winch with new zip ties. The winch can then be removed from the crate by reversing the steps used to secure it to the crate in step 2 above.
The crate can then be reassembled by reversing the setup instructions in step 1 above.
