ERECTING THE TRIPOD STAND AND TELESCOPIC MAST
When using the Tripod Mast adequate safety precautions should be taken to ensure the safe use
of the mast. These include the use of cordon tape and cones to restrict access to the survey area.
2. 1. Preparing the tripod base
1. Check that all items of equipment as listed in TAD-002 are available.
2. Using map identify the location and bearing from the ST location to the Central Terminal
serving the area. Identify most probable position for mounting CRU. Position the telescopic
mast as near to that location as possible. If the tripod cannot be positioned at the selected
location the tripod should be erected in line with the radio path in front of the location. More
than 10 metres in front of the location will reduce the reliability of the results.
3. Ensure that the feet are fully engaged in the main body of the mast and safely retained.

5. Turn foot locking screws anti-clockwise to release feet. Pull feet clear of the retainers to
release the legs. See Figure 3.
6. Withdraw the locking pins and swivel the legs into position, Use the locking pins to lock the
legs into the leg swivels. Twist the locking clip at right angles to the pin to prevent the pin
falling out. It may be necessary on soft ground to provide a board to give extra support to the
tripod wheels.
