Fast dynamic response ZOOMLION ZR280C Rotary Drilling Rig

Structural stability advantage

Double large triangular back variable amplitude mast, taking into account high rigidity and rock stability, the mast can be folded back, and does not need to be completely disassembled for transition. The transportation height is low, and disassembly and assembly are time-saving
Large section mast, enlarged slewing support, strengthened telescopic track chassis, low center of gravity design, minimal shaking of the whole machine during hard layer drilling, and good verticality of the drilled hole.
The standard drill rod anti roll device suppresses the lifting of the drill rod during pressurization, protecting the drill rod and achieving higher precision in deep hole construction.

Power and drilling capability

Three speed reducer power head with sufficient torque reserve, maximum torque of 300kN · m; adjustable multiple speeds, suitable for soil layers, sand layers, and moderately weathered rock layers
Dual speed pressurized oil cylinder+intelligent power matching system, capable of automatic power distribution, high efficiency in drilling large diameter and deep holes
Construction capability: Maximum aperture of 2.5m, maximum depth of friction rod of 88m, machine lock rod of 58m, and optional deepening drill pipe kit as needed.

Highlights of the winch system

Mid mounted single row rope main winch, driven by dual motors, with high lifting force; The single-layer steel wire rope structure reduces the compression wear of the steel wire rope, significantly extends the service life of the steel wire rope, and reduces the cost of consumables.
