WALMACH’s roller in road construction tackles Iraq’s harsh rebuild. Engineered for 50°C+ heat and dust, this 33 ton single drum roller WS336HD delivers reliable compaction, ensuring infrastructure progress with strong support.
I. Project Background
During Iraq’s large-scale post-war reconstruction, the roller in road construction has become crucial for rebuilding critical infrastructure. The challenging conditions—dust storms and extreme heat—demand exceptional durability from every heavy road roller on site.
II. Client Background
The client is a prominent state-owned enterprise under the Iraqi Ministry of Construction and Housing, with over 40 years of experience in national infrastructure development. As the primary contractor for highway reconstruction projects, they are entrusted with rehabilitating the nation’s crucial transport corridors connecting major economic hubs.
III. Client Requirements
Their primary requirement is a large single drum vibratory roller weighing over 30 tons to meet the high-compaction standards for the subgrade and asphalt layers. The equipment needs to be able to withstand dusty environments and summer temperatures exceeding 50°C (122°F), while also being easy to maintain and having timely spare parts supply to maximize the chances of the project being completed on time.
IV. WALMACH Solution
To address Iraq’s extreme heat and dust, WALMACH tailored its solution with the heavy road roller – 33 Ton WS336HD single drum roller, incorporating key design enhancements:
- Enhanced Cooling & Heat Resistance: We upgraded the road roller machine with an oversized, composite cooling system, boosting the hydraulic oil and engine cooling capacity by 30%. This specifically counters extreme temperatures above 50°C, preventing hydraulic system shutdowns due to overheating.
- Superior Dust Protection: To combat pervasive sand and dust, we equipped the vibrating compactor roller with desert-grade heavy-duty air filters and multi-stage hydraulic oil filtration. This provides far greater protection for the core power and hydraulic systems than standard models, significantly reducing failure rates caused by dust ingress.
- Reinforced Structure for Heavy-Duty Use: Considering the potentially unstable subgrades on post-conflict sites, we reinforced critical stress points on the drum housings and machine frame. This ensures overall durability and high availability, even under harsh conditions like compacting broken or impacted surfaces.
V. Cooperation Overview – WS336HD Roller in Road Construction
Our collaboration began with an in-depth on-site assessment. The WALMACH technical team visited Iraq and, after confirming the local operating conditions, immediately provided a customized service plan. This plan included initial stock of key spare parts, localized operating manuals, and intensive on-site operator training, completely eliminating the customer’s concerns about after-sales support.
Subsequently, the first batch of WALMACH WS336HD road rollers was successfully delivered and immediately put into use on a highway project on the outskirts of Baghdad, where they have maintained stable and efficient operation ever since.
VI. Client Feedback
“The WALMACH WS336HD rollers have demonstrated outstanding performance. Their powerful compaction capability has significantly boosted our construction efficiency. In the extreme heat and dusty environment, the equipment has consistently maintained high availability, with no downtime attributed to high temperatures. WALMACH’s after-sales service is highly responsive, with timely technical support and parts supply. They are a trustworthy long-term partner for us.”
