A tripod is an essential part of a bailer boring set (cable tool drilling equipment). Also drillings at greater depths, or the application of heavier augering or soil core sample equipment require the use of a tripod.
In selecting a tripod, working height, weight, and maximum load capacity (= tensile force) are usually determinant factors. However, the range of application is of such a magnitude, that the selection of the tripod depends strongly on the kind of work that may have to be performed with the selected tripod besides the performance of soil drillings.
Our program includes a lighter version (tensile force 4 kN, art. no. 02.01.01) and a heavy version (tensile force 18 kN, art. no. 02.01.04).
Each leg of the tripod consists of three parts. On top, a snatch block is fixed to both tripods, which is used as a guider for the cable of the hand-operated winch that is to be used with the tripod. At the bottom, the legs of the heavy version are provided with a point to prevent sliding. To increase the bearing capacity, particularly in soft soils, a separate baseplate is provided for each leg. The legs of the lighter one are provided with base plates.
The heavy tripod is provided with a frame to fix the heavy hand winch, and can be provided with 5 step supports.
The three-piece aluminium tripods meet the specific requirements which apply to light, easily operable tripods. These parts can be coupled very quickly, and are of limited length, making it very easy for the user to set them up very quickly. The high quality aluminium is very light weight and requires nearly no maintenance.
Because of the limited weight and length of the various parts, the tripods are easy to transport (even in a normal station wagon).
