The Automatic Trip Hammer is designed for carrying out the Standard penetration Test (SPT) to BS 1377: Part 9: 1990. SPT Drive Rods and a split Tube Sampler are connected to base of the anvil, and driven into the ground by the falling weight.

The inner shaft acts as a guide on which the weight drops with minimal resistance and strikes the anvil squarely.
