A：Small drilling rigs are versatile and can typically perform various drilling functions, including Kelly drilling, CFA drilling, DTH hammer, etc. And we also provided the drill rig customization to meet the high demand of the market.

A：We retained the original hydraulic and electrical systems of the excavator. This was done for two primary reasons: first, it facilitates easier maintenance in the future, and second, it will be convenient to revert this drilling rig back to an excavator. Additionally, the additional units added during the modification don’t interfere with the excavator's original operating system, making it easy to operate and effectively improving work efficiency.
