All‑round Adaptability ZOOMLION ZR280C Rotary Drilling Rig

Power and construction capability

Three speed reducer power head, low-speed high torque, sufficient torque reserve, strong rock penetration ability, can cope with soil layers, sand layers, strong/medium/weakly weathered rocks, suitable for building, bridge, infrastructure, support pile and other projects
The lifting force of the main winch is 340kN, with a mid mounted single row rope structure and a single-layer steel wire rope, which extends the service life of the steel wire rope; Dual speed pressurized oil cylinder, adjustable pressurization speed, flexible switching between slag excavation and rock entry
Maximum aperture of 2.5m, maximum drilling depth of 88m (optional drill pipe can reach 94m), 298kW high-power engine, equipped with 2.0 version power matching+ultimate load control, on-demand power output, fuel-efficient while protecting the hydraulic system

structural stability

The double large triangular mast has a variable amplitude structure at the back, and the mast oil cylinder supports a larger angle, making it highly resistant to overturning during operation; Large section mast, large diameter slewing support+reinforced chassis, making the whole machine more stable under heavy load and inclined rock conditions
Upgrade the anti torsion and wear-resistant drill rod, improve common pain points such as drill rod cracking and spring failure, and improve the reliability of long-term high load construction

Intelligence, Security, and Operation

The new generation electronic control platform is equipped with the Zhonglian eHome APP, which allows remote viewing of working hours, fuel consumption, fault location, and equipment location, facilitating project management and maintenance.
360 ° panoramic monitoring+13 safety monitoring protections to prevent misoperation; Brand new driver’s cab, wide field of view, optimized human-machine interaction panel, high comfort for long-term operations

Transition and operation advantages

The double large triangular structure balances operational rigidity and transportation convenience, with a foldable mast to meet the requirements of large transportation, and short disassembly and transfer time.
The core hydraulic and power components are domestically produced in a mature supply chain, with easy procurement of accessories and lower maintenance costs compared to imported models of the same level. The construction site attendance rate is high.
