Product Overview
This drilling rig is suitable for single‑layer seismic exploration, mine prospecting, and geological structural surveys in mountainous areas, farmlands, river networks, and forested regions—provided there is no risk of wellbore collapse. It is a lightweight, practical, and highly efficient piece of field‑ready drilling equipment.
The remote throttle lever on the handheld control panel is easy to operate and highly reliable. The gearbox is equipped with a centrifugal clutch. When the throttle is adjusted to reduce the engine speed to idle, the gearbox ceases to transmit power, thereby minimizing the number of engine start‑stop cycles.
