Product Description

SPT Hammer
SPT Auto Trip Hammer is produced complying with the Standard Penetration Test (SPT) to BS 1377: Part 9: 1990.
The Automatic Trip Hammer is manufactured for complying with 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 Automatic Trip Hammer comprises a weight of 63.5 kg complete with pick-up and self-tripping mechanism that ensures that the weight has a free-fall of exactly 760 mm. The inner shaft acts as a guide that permits the weight to drop with minimal resistance and ensures that the weight strikes the anvil squarely.

The SPT anvil thread usually is processed with a 1.1/2" B.S. whitworth to fit our standard SPT rods. Adaptors to other types of drill rod can be supplied on request. The overall length of the hammer is 2.6 m extended and 1.8 m when unextended. The total weight of the hammer is 110 kg.
