- Engine Power:212-270kW/em>
- Max. Output Torque:210-240KN.m
Features
As a multi-functional machine,HFR70 can realize the quick switching of functions such as crowd cylinder, crowd winch to meet more different construction needs.
It adopts Isuzu electronically controlled turbocharged engine with lower fuel consumption and convenient service.
The rotary drive and main winch performance is increased by 20%, so the work efficiency is much higher.
The main and auxiliary winches both adopt the single-row rope technology.The service life of wire rope is 2-4 times longer than that of multi-layer rope, which makes the cost lowerThe double jib parallelogram luffing mechanism has a large support angle and a 16% increase in support range, which makes the operation more stable.
The hydraulic system adopts negative flow control technology which has a fast response and good handling performance.
High-power temperature-controlled independent hvdraulic oil cooler can meet the construction requirements of high-temperature areas and adiust the fan speed according to temperature changes to achieve energy saving.
The intelligent control system can achieve functions such as automatic adiustment and display of mast perpendicularity. automatic slew, automatic spin-off, automatic lifting & concrete pouring and pile type display, etc.
The bus panel design is adopted to prevent misoperation.The chassis can be equipped with transport legs (optional) and remote control operation to achieve easier and safer site transfer and transportation.
