Light duty (140 lb.) drive weights are primarily used for "Standard Penetration Tests" with drive type samplers.
Heavier drive weights are used to drive pipe, casing, chopping bits, boulder busters and heavy duty samplers. They are operated like a pile driver.
Drive weights are available with or without a chain sling.
