High efficiency：full set of imported hydraulic system，2*160 ml/r main pump；imported Cummins engine from the United States；rotary drive with multi shift working model (standard, soil, strong weathered rock, rock, soil discharge)；crowd cylinder ( high speed+ low speed) for lifting and lowering rotary head
More stable & reliable：5th generation rotary drive；Zoomlion’s self-made Kelly bar；main winch with single-layer-rope drum and twin reducers mechanism
More comfortable, safe and intelligent：new generation cab; optimized control panel & monitor screen; “one button for soil-discharge, one button for hole-cleaning”; one key for folding cathead.
The rear main winch with single-layer-rope drum and two gear box mechanism, which extends service life of the steel wire rope significantly.
High construction efficiency thanks to big flow main pump, multi-gear rotary drive, and two-speed crowd cylinder.
More stable structure and stronger bearing capacity thanks to the 5th generation rotary drive, large supporting angle of the mast cylinder, lower center of gravity, and reinforced chassis.
One key for folding cathead, fixed mast support. Equipment can be transferred easily and quickly.
Version 2.0 power matching and limit load control technology, working efficiency increased by 10%.
New generation cab with better vision. More comfortable operation, new electrical controlpanel.360-degree full view monitoring.
Options: Crowd winch model ZR255D,spin-off, auto-lubrication.
