Electric Rotary Drilling Rig

The YTR166AE suits urban piles up to roughly 1.5 m diameter and 40–50 m depth — the standard for mid-rise buildings, metro stations and viaduct piers. Move to the YTR206AE for 1.8–2.0 m diameters and 60–70 m depths on bridge foundations. Oversize the mast and the rig wastes daily mobility; undersize it and you cannot finish the bore in one clean pass.

Choose a pure-electric YTR166AE or YTR206AE where the site has grid power or a fast-charge pad and the machine returns to a yard between shifts. The on-board battery covers a full working day on typical urban piles and can be fast-charged during the lunch break. Choose the range-extended YTR236HES where the job moves between remote sites with no mains supply — it drills electrically most of the time but starts the generator when the pack runs low.

An electric rig draws a heavy load, so confirm the site power supply before arrival. Standard 380 V industrial supply covers overnight slow charging; DC fast charging during the shift needs a dedicated pad. Send us your daily meter depth and pile count and we will size the battery and charger to the duty cycle instead of guessing.

Dense urban sites run up against noise and emission limits. Recommended class: YTR166AE or YTR206AE pure-electric, drilled before 7 a.m. without disturbing residents.

Metro boxes are cut deep and surrounded by live buildings. Recommended class: electric rig with low headroom boom configurations where clearance is tight, and zero exhaust inside the box.

Viaduct piles are larger and deeper. Recommended class: YTR206AE or range-extended YTR236HES for the 1.8 m, 60 m bores typical of railway bridges.

Sensitive sites ban diesel exhaust. Recommended class: pure-electric YTR166AE for the low-noise, zero-emission requirement these contracts usually write in.

Where there is no mains power on a greenfield site. Recommended class: range-extended YTR236HES, which keeps electric drilling performance without depending on a fixed charger.

On typical urban bored-pile work the YTR166AE and YTR206AE cover a full 8–10 hour shift on a single charge. The range-extended YTR236HES adds an on-board generator, so it keeps working indefinitely where there is no charge point at all.

Overnight slow charging on standard 380 V industrial supply tops the pack fully. DC fast charging during a lunch break gives enough energy for several more hours of drilling. We match the charger rating to your shift pattern after you share the daily meter plan.

An electric rig produces zero local exhaust and runs at roughly 75 dB at ear level instead of the 95 dB typical of a diesel machine. That lets you keep working next to hospitals, schools and residential blocks without breaching noise or low-emission zone rules, and cuts energy and maintenance cost per meter.

The YTR166AE and YTR206AE are pure-electric and need a charge point. The YTR236HES range-extended model carries a small generator that tops the battery on the job, so it works on remote sites with no mains supply while still drilling electrically.

The YTR166AE suits piles up to about 1.5 m diameter and 40–50 m depth. The larger YTR206AE handles 1.8–2.0 m bores to 60–70 m. Exact figures depend on mast and tooling configuration, which we quote against your pile plan.

Standard models ship within 30–60 working days after deposit; customized masts or tooling add time. The rig carries a 12-month warranty, with spare-parts kits and 48-hour technical support from the export team.
