Introduction:  In modern road construction, efficiency and cost control are top priorities for every project team. Traditional roadbed preparation requires multiple machines working in sequence, leading to coordination challenges and significant waste of time and resources. Hengwang Group's HW22DE bulldozer with ripper revolutionizes this process with its innovative multifunctional design. This equipment integrates three critical functions - soil loosening, grading, and preliminary compaction - into a single machine, truly achieving the concept of "one machine handles it all."  

1. Why Choose a Bulldozer with Ripper?   

Loosening Function: Conquering Hard Soil Layers

(1) Powerful Performance: Equipped with a 175kW high-power engine and heavy-duty hydraulic ripper, the HW22DE easily breaks through frozen ground, compacted roadbeds, and even rocky soil layers with a maximum loosening depth of 800mm.  

(2) Smart Adjustment: Operators can real-time adjust ripping angle and depth based on soil hardness, preventing overload and extending machine life.  

(3) Efficiency Comparison: In an Australian mining project, HW22DE improved soil-breaking efficiency by 60% compared to traditional excavator-dozer combinations, reducing project duration by 40%.  

Grading Function: Quick Transition, Seamless Operation

(4) One-Touch Conversion: Transition from ripping to grading mode in just 30 seconds without waiting for additional equipment.  

(5) Extra-Wide Blade: The 7.5m³ capacity blade covers 40% more area per pass than standard dozers, delivering more uniform grading results.  

(6) Intelligent Assistance: The cabin features an HD display for real-time surface level monitoring, reducing manual rechecking time.  

Compaction Function: The Hidden Advantage  

(1) Weight Benefit:At 24,600kg, the machine provides compaction force equivalent to small rollers.  

(2) Vibration Technology: High-frequency micro-vibrations during ripping help rearrange loose soil particles for better subgrade density.  

(3) Track Design: Special tracks maintain ground pressure at just 0.072MPa, preventing over-compaction and rework.  

2. Four Core Advantages of HW22DE  

1. Cost Savings  

(1) Single machine replaces multiple equipment, reducing rental and labor costs  

(2) Optimized fuel efficiency saves 15-20% compared to traditional methods   

2. Efficiency Boost  

(1) Eliminates equipment scheduling delays, improving productivity by over 50%  

(2) 450L fuel tank enables 10+ hours of continuous operation   

3. Superior Adaptability  

(1) CE certified for extreme conditions (-30°C to 50°C)  

(2) Modular design allows quick attachment changes (ripper teeth/blades)   

4. Intelligent Operation  

(1) ISO-certified cabin with noise reduction and dustproofing  

(2) Air purification and climate control ensure operator comfort  

3. Globally Proven Reliability  

As China's leading construction machinery manufacturer, Hengwang Group exports to 180+ countries. The HW22DE bulldozer with ripper has undergone rigorous testing:  

(1) 2,000+ hours endurance trials  

(2) ISO9001 and CE certified  

(3) Field-proven across Southeast Asia, Africa, and South America   

Client Testimonial:  

"We deployed 3 HW22DE units for a Kenya highway project. What previously took 2 weeks for roadbed preparation now finishes in 8 days, with 18% lower fuel costs." JMC Construction Project Manager, Kenya
