High overall efficiency XR280D Rotary drilling rig

Power and rock penetration performance

Equipped with Cummins high-power electronically controlled turbocharged engine, it has sufficient power reserves, speed regulation, adjustment, fuel saving and durable, and is suitable for long-term heavy load construction Tiktok.
The rated output torque is 280kN · m, and the power head comes with a dedicated rock entry gear; Multi speed adjustable from 7-20r/min, excellent drilling ability in moderately weathered rock, hard clay, and pebble layers
Imported Kawasaki main hydraulic components and load sensitive hydraulic system, with smooth composite action and on-demand power distribution, reducing ineffective energy consumption.

Stable structure of the whole machine

Telescopic special track chassis, widened tracks, large diameter slewing bearings, with minimal shaking of the heavy-duty perforated machine body; After the tracks retract, the overall width of the machine narrows, making trailer transportation convenient.
Thickened box type rotary platform and high-strength mast structure; The mast supports tilt angle adjustment of ± 5 ° forward and backward, ± 4 ° left and right, and has strong adaptability to slopes and inclined sites.
Optimize the double box variable amplitude mechanism, balance the force, and prevent deformation during long-term operation.

Windmill system, reducing consumable costs

The rear single row rope structure of the main and auxiliary winches eliminates multi-layer compression and wear of the steel wire rope, increases the service life of the steel wire rope by 2-4 times, and reduces daily consumables expenses.
The main hoist has a lifting force of 260kN, fast lifting speed, and sufficient resistance for deep hole drilling and handling collapse holes.
