WALMACH 30 ton single drum vibratory roller for road projects in Iran’s mountainous terrain delivered superior compaction and 25% better gradeability, earning full client recognition for reliability.
I. Project Background
New city development in Tehran requiring large-scale earthwork compaction and base course treatment. The hilly and mountainous terrain demands equipment with superior climbing capability. As a professional road roller manufacturer, WALMACH provided the optimal roller for road construction in this challenging environment.
II. Client Background
The client is a leading Iranian construction conglomerate with over 25 years of specialized experience in large-scale infrastructure development. Holding the highest classification license from Iran’s Ministry of Roads and Urban Development, the company has successfully executed numerous national priority projects including the Tehran-Shomal freeway and multiple new city development initiatives.
III. Client Requirements
The client required a high-performance single drum vibratory roller exceeding 26 tons, capable of delivering high-density compaction on complex terrain while demonstrating exceptional gradeability for mountainous operations. Reliability and timely spare parts support were equally critical considerations given the challenging international supply chain environment.
IV. WALMACH Road Roller Solution
WALMACH WS265HD 26 ton fully hydraulic single drum vibratory roller
Following in-depth technical discussions with the client, ultimately confirmed the WALMACH WS265HD 26 ton fully hydraulic single drum vibratory roller (dual-drive & dual-vibration) as the optimal solution. Customized enhancements were implemented to address Iran’s specific operational challenges：
- Enhanced Dual-Drive Dual-Vibration System
The fully hydraulic dual-drive technology combined with a high-capacity vibration system ensures exceptional traction and compaction force on steep slopes, delivering a 25% improvement in gradeability for effective mountainous terrain operation.
WALMACH Road Roller Climbing Ability - Upgraded Cooling & Sealing System
Optimized heat dissipation for hydraulic and vibration systems, coupled with reinforced sealing at critical components, ensures reliable performance in Iran’s continental climate with its significant temperature variations and dusty conditions. - Improved Structural Durability
The reinforced frame and drum support structure enhance overall machine durability, guaranteeing extended service life and consistent performance during continuous high-intensity operations.
V. Cooperation Overview
During the project development phase, we presented the client with detailed case studies of our roller performance in challenging terrains, particularly highlighting successful applications in Guizhou’s mountainous regions in China. These case studies clearly demonstrated our hydraulic road roller exceptional climbing capability and reliable operation under complex geological conditions.
Following thorough on-site testing and comparative evaluation against other brands, the client confirmed that our roller’s gradeability and compaction performance met their stringent requirements for Tehran’s hilly terrain. This technical validation, combined with our competitive solution, ultimately led to their decision to select WALMACH as their equipment partner.
VI. Client Feedback
“The WALMACH WS265HD road roller has demonstrated exceptional compaction performance and reliability on slopes and under heavy loads. Its dual-drive system effectively solved construction challenges in complex terrain. The equipment runs stably with high availability, and the service team responds quickly. WALMACH is a key partner in advancing our new district project.”
