Product Description

80m Coal Mining Rock digger Hydraulic Rotary Drilling Rig Zr280c-2

Highlights:
 

1.Zoomlion initiative Double Big Triangle Back Folded kinematic and mast system, which ensures high stability of rock penetration and convenience of transit.
 

2.The rear main winch with single-layer-rope drum and twin reducers mechanism, which extends service life of the steel wire rope significantly.

3.Rotary drive with three motors, which ensures large torque, and stronger construction capacity.

4.High construction efficiency thanks to version-2.0 power matching and limit load control technology, multi-gear rotary drive,and two speed crowd cylinder.

5.More stable structure and stronger bearing capacity thanks to enhanced mast section, large slewing support, and reinforced chassis .

6. New generation cab with better vision, more comfortable operation, new electrical control panel. 360 degree full view monitoring.

Product Description

• A classic model that dominates the market, with stable performance and reliable quality.

• Rotary drive with large torque and high reserve coefficient, which ensures stronger construction capacity.

• Using more flow main pump and multi-gear rotary head, which ensures high construction efficiency. 

• Stronger ability to enter the rock, due to the front main winch and the center of gravity moving forward.

• Equipped 22 self auto-check , safety and performance monitoring

• Optional: Spin-off.
