Single-hole efficiency is high ZOOMLION ZR280C Rotary Drill Rig

Stable structure, strong rock penetration

Unique * * double large triangular back variable amplitude mast * *, balancing operational stability and parallelogram structure transition advantages; Large section mast, large slewing support, reinforced chassis, low center of gravity, good anti sway; Three speed reducer power head, low-speed high torque, outstanding construction ability in weathered rock

High construction efficiency and controllable fuel consumption

Multi speed power head+dual speed pressurized oil cylinder, 2.0 version power matching+ultimate load control, high power utilization rate; Mid mounted single row rope main winch, one tube dual machine structure, high lifting force, single-layer steel wire rope wear-resistant and longer service life; The maximum drilling depth can reach 94m, suitable for large-diameter piles

Convenient transition

The mast can be flattened backwards, and the whole machine can be transported by a single bike with drill rods, without the need to split large parts, saving trailer costs. The construction site transfer is fast, which is very suitable for multi-point and short distance field adjustment in China, and foreign trade shipping is also worry free
