It is generally restricted to a maximum of 15%, depending on the climatic zone defined in IS 287.

What type of wood is recommended for picks and beaters?

Tough hardwoods with high impact resistance, such as Sal, Shisham, or Babul, are preferred.

This standard specifies the requirements for material, dimensions, workmanship, and testing of wooden handles used for picks and beaters. It ensures handles possess the appropriate impact resistance, correct grain orientation, and moisture content for safe and durable use in manual earthwork and excavation.

Practical Notes

Grain orientation is critical; always ensure the wood is straight-grained to prevent the handle from snapping under sudden impact loads.

Verify the moisture content before fitting the tool head to avoid shrinkage, which leads to loose and dangerous tool fittings.

Handles must be free from defects like large knots, cracks, and fungal decay.
