Product Feature

Strong construction capacity of large piles:

• A new generation of high-power countryIVEngine,Power is strong、Less emission、Low fuel consumption,Equipped with large-displacement power head motor、High flow pump valve,Both high speed and high torque,Surging performance,Powerful;

• Powerful main winch lifting capability,Safe、Efficient;

And that construction stability is high:

• Large section mast、High strength double boom、Large-section reinforced rotary table;

• Heavy-duty slewing bearing with large diameter、Low center of gravity design,The construction shaking is small、And that stability is high;

Sensitive control:

• Upgrade the main valve function and control program,The operation is smoother;

Convenient transportation:

• The mast is collapsible,One-key folding of hanging anchor frame、Dismantling-free mast support;

• The height of the whole machine is low,The transfer transportation is convenient;

Intelligent control:

• Pressurization self-adaption、Floating Pedal,Wire rope pre-tightening、720-degree full-viewing angle stereo monitoring、 Cell phone APP Detection function;

Quality appearance:

• Optimize product detail design:Combined guardrail、Pedal,Mast pipeline double-row arrangement、Improved pipeline bracket, etc.;

Convenient maintenance:

• Winding、Main Valve、Large space for slewing maintenance;

• Machine filter、Centralized maintenance of diesel filter;

• Add high precision bypass filter,Long-lasting cleaning of hydraulic system。
