SPT Hammer

The SPT Hammer is designed for driving the split tube sampler or cone assembly required for the Standard Penetration Test (SPT) or Cone Penetration Test (CPT).

The hammer consists of a sliding weight with a mass of 63.5 kg complete with pick-up and self-tripping mechanism that ensures that the weight has a free-fall of exactly 750 mm.

The inner shaft acts as a guide which permits the weight to drop with minimal resistance and ensures that the weight strikes the anvil squarely.

The hammer is supplied with a safety cross bolt which secures the sliding outer sleeve to the inner guide rod when the hammer is not in use or during transport.
