Spt Automatic Trip Hammer Sampler for Soil Test
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 hammer comprises a drop weight of 63.5 kg and a pick-up and selftripping mechanism that ensures the weight has a free fall of exactly 760mm.
The inner shaft acts as a guide on which the weight drops with minimal resistance and strikes the anvil squarely.
The trip hammer is supplied with a Safety retaining bolt to prevent the weight from sliding when the hammer is not in use or during transport.
