What is a fully hydraulic portable drill rig?
A fully hydraulic portable drill rig is an exploration drilling machine in which every function — rotation, feeding, hoisting and mud pumping — is driven hydraulically, and whose frame is built in modules that can be separated, carried into remote terrain and reassembled on the drill pad. Unlike a conventional spindle rig on a fixed skid, a portable rig is designed around access: no road, no problem, as long as the modules can be moved by vehicle, pack animal or helicopter.
The FULONGZUAN YB series (YB-500, YB-800, YB-1000) is a top-drive portable rig family that combines the advantages of traditional hydraulic drills and lightweight rigs: modular construction, high torque and high pull-back force. Its infinitely variable top-drive rotary head combines a mechanical 2-speed gearbox with hydraulic stepless speed control, and a hydraulic direct-drive mud pump delivers stepless flow adjustment and can work with solid-phase mud — the configuration the manufacturer positions for green exploration programmes.

Main Features
The rig's engineering centres on the top-drive head: mechanical 2-speed gearing covers the high-torque range while hydraulic stepless control trims speed continuously within each range, so the driller can match rotation to changing ground without stopping. The BW100/6 mud pump is driven directly by hydraulics — no separate engine — and its displacement adjusts steplessly, which keeps flushing control precise in broken ground and allows solid-phase mud systems used in environmentally sensitive (green exploration) areas.

Frequently Asked Questions
How deep can a portable drill rig drill?
It depends on rod size and rig model. In the FULONGZUAN YB range, the YB-1000 is rated at 1,300 m with BTW rods, 1,000 m with NTW and 600 m with HTW; the smaller YB-500 starts at 600 m BTW.
Why choose a portable rig instead of a crawler rig?
Access. A portable rig disassembles into modules that can be transported to mountainous or roadless sites and assembled on a small pad, while a crawler rig needs vehicle access. Choose the crawler rig when depth, torque and pull-back demands outgrow the portable class and the site is reachable.
What does 'fully hydraulic' change in practice?
All working functions are hydraulic, so speed and feed are infinitely adjustable, overloads are absorbed by the hydraulic system rather than mechanical clutches, and one power pack can be scaled — the YB series uses two, three or four Kubota diesel units as model size grows.
Conclusion
A fully hydraulic portable drill rig is the tool for exploration programmes where the drill site is the hard part: remote, steep or environmentally sensitive ground. The FULONGZUAN YB-500/800/1000 family covers 500–1,300 m class wireline drilling in that format.
