FAQ (Frequently Asked Questions)

What international standards does this equipment comply with?

The device fully complies with ASTM D1586, BS 1377-9, EN ISO 22476-2, and GB 50021. It supports Standard Penetration Testing (SPT) and Heavy Dynamic Penetration Testing (DPT).

Can the hammer weight and drop distance be adjusted?

Yes. While the standard configuration is a 63.5kg hammer with a 760mm drop, the modular design allows for adjustments (10kg, 28kg, 50kg) to accommodate light, medium, or super-heavy probing requirements.

What are the advantages of electric drive over manual rope pulling?

Electric automation eliminates human error, friction loss from ropes, and inconsistent drop heights. It ensures a precise 760mm free fall and a constant hammering frequency, leading to much more accurate N-values.

How is the equipment powered in remote field locations?

For sites without mains power, we provide high-performance, portable generators designed to provide stable power to the electric lifting and control systems in harsh environments.

How does the system record the number of hammer blows?

The equipment features an integrated intelligent counter. Industrial-grade proximity sensors automatically record each drop. Advanced versions can sync with displacement sensors to record N-values per 10cm or 30cm of penetration.

Is the equipment durable enough for hard soil layers?

Absolutely. The drill rods are made from high-strength alloy steel (42CrMo), and the conical probes are made from ultra-high hardness wear-resistant alloys, ensuring a service life 3-5 times longer than standard carbon steel.
