Product Reviews
We put the YuGong RC400 to the test in Quebec's hard rock formations. It consistently achieved the full 400-meter depth without any power loss. The penetration rate in granite is impressive, averaging 15 meters per hour. YuGong Machinery definitely delivered on their depth promise
The reverse circulation system on this rig is flawless. We get uncontaminated samples directly from the valve, which is crucial for accurate assays. The YuGong RC400 collects samples twice as fast as our old top-hammer drill. This speed has cut our exploration timeline in half.
Efficiency is key for our projects. The YuGong Machinery RC400 features automatic feed control, allowing one operator to manage the rig easily. The hydraulic rod handler saves us at least 2 hours per shift. High efficiency means lower operational costs for us.
Time is money in exploration. With the YuGong RC400, the sample recovery is almost instantaneous. There's no need to pull the rods to check cuttings, which saves a huge amount of time. We drilled 12 holes in one week—a record for our team
We tested the RC400 in both frozen soil and sandstone. The drilling speed remained consistent, and the sample integrity was maintained throughout. YuGong Machinery configured this rig perfectly for deep RC drilling. It’s a reliable workhorse for any serious explorer.
