HAMM compactors 311 lay foundations for NH-52 in Punjab


In recent months, HAMM compactors have been laying the foundations for a better road network in Punjab. One example of this is the construction of the new National Highway NH-52 from Moga to Shahkot. For compaction of the subbase, the construction firm Dilip Buildcon Ltd. employed several HAMM compactors 311. They are “made in India” – produced in WIRTGEN India’s own factory in Pune.

In the federal state of Punjab, a national highway, the new NH-52, is under construction with two lanes in each direction. The new road will provide many communities with better links to the national road network. In some parts, the existing carriageways are being refurbished and widened; in other sections, totally new roads are being constructed.

Earth work and asphalt construction on the almost 33 km long section was carried out by Dilip Buildcon Ltd., a construction firm from Bhopal (Madhya Pradesh). The company has been successfully working with WIRTGEN India for almost 10 years and has now assembled a fleet of more than 100 HAMM rollers. For compaction of the subbase for the new road around Moga, Dilip Buildcon employed a total of 8 type 311 compactors. For the asphalt compaction, a number of HAMM type HD 99 tandem rollers were used. HAMM produces both machine types in its own factory in India.

The 311 compactor with the unique HAMM 3-point articulation was developed especially for India in a joint German-Indian team of engineers and has been in production in Pune for some years. With an operating weight of 11 t and a 2.14 m wide vibration drum it brings high compaction force and a large static linear load of up to 30 kg/cm to the construction site. This enables the machine to perform a wide range of tasks with ease.


The environment-friendly engine in the 311 compactor is in accordance with CBV BS III and is remarkably quiet and economical. To take account of the often extremely high temperatures in India, the engine of the compactor has been specially designed to facilitate operation at up to 55°C.

Alongside the performance and reliability of the HAMM rollers, service quality is a decisive factor for Dilip Buildcon Ltd. This is where HAMM, that is to say WIRTGEN India, stands out with its competent staff, a dense network of service locations and prompt delivery of spare parts and wearing parts.
