This section is intended to be a summary of the method of operation. Full operating instructions are provided with the product, including a CD-ROM.
Initially the unit must be adjusted to suit the particular pile section being threaded – no additional items will be required. This process is described in detail in the operating instructions. Once set up the UniSPT is basically used in the following way:
|
1.
The Lower Section of the threader is taken on to the last pile
in the panel
|
 |
| 2. The Arms are then locked in position via the Swing Arm Clamp Bolt | |
 |
|
| 3. The spigot of the Upper Section is then lowered in to the socket of the Lower Section and locked into position. This section contains a sliding and sprung loaded Vice Block which is cocked into the ‘loaded’ position. The pile to be threaded is clamped into the Vice Block. |  |
4. The crane now lifts the pile to be threaded until its bottom edge is just above the previous pile in the panel. The spring pressure on the Vice Block forces the pile across to its engagement position. As the pile is lowered it interlocks. The threader is then released at top frame level ready for the next pile. 5. If threading single piles the next pile will be an opposite hand. To accommodate this the Lower Section can be rotated through 180o on the previously threaded pile then the top section attached as usual. |
