Zoomlion Builds Excavator For Middle East Heat

25 Jun 2026 CW Team

Zoomlion Heavy Industry Science & Technology has developed a 21-tonne crawler hydraulic excavator designed for extreme heat, dusty worksites and prolonged breaker operations in the Middle East.

The excavator was developed by a team led by Wu Baoshuo, Deputy Director of the Medium and Large Excavator Research Institute at Zoomlion Earthmoving Machinery Company. The machine recently received the Outstanding Flagship Product Award at Zoomlion’s Seventh Science and Technology Innovation Conference.

Designed for municipal construction, utility projects and mining operations, the excavator is built to work in conditions where temperatures can exceed 50 degrees Celsius. It is also suited for sites where hydraulic breaker work may account for more than 70 per cent of operating time.

To address heat-related challenges, the engineering team redesigned the airflow layout and optimised the cooling core for improved heat dissipation. Key structural components were strengthened, while welds were refined to reduce stress during repeated impact operations.

The machine also includes improved dust protection through an enhanced air intake system and better cab sealing. The team tested the upgrades at customer worksites in the Middle East, using sensors to collect operating data and completing thousands of breaker cycles to refine the design.

Zoomlion said the project involved teams across product development, testing, manufacturing, technical support and overseas operations. Its testing centre at the company’s headquarters also supported three months of high-frequency breaker durability testing.

The development highlights Zoomlion’s focus on building construction equipment suited to demanding regional operating conditions.

Centre Prioritising Energy Security With Coal Gasification

Union minister for Coal and Mines G Kishan Reddy said the Centre is prioritising energy security through a strategic shift to coal gasification and has announced incentives totalling Rs 460 billion (bn) to support the effort. He said more than 35 companies will start coal gasification activities in India within two months and that the government is encouraging firms that bring technology to close the domestic technology gap. The minister described the initiative as aimed at reducing import dependence and developing indigenous capacity. India has the fifth-largest coal reserve in the world, and..

BHEL and Coal India Invest Rs 250 bn in Odisha Gasification

Bharat Heavy Electricals (BHEL) and Coal India (CIL) are jointly investing Rs 250 billion in a coal gasification project in Odisha, with the Prime Minister laying the foundation stone in Jharsuguda. Union Coal and Mines Minister G Kishan Reddy described the initiative as a transformative shift in coal utilisation that will open industrial avenues for the state. The project moves coal beyond conventional power generation to industrial feedstocks. Coal gasification will convert coal into synthesis gas, a versatile feedstock for chemicals, fertilisers and synthetic fuels, and the technology is ex..

BCCL Hands Over Dugdha Coal Washery To JSW Steel

Bharat Coking Coal has handed over the Dugdha Coal Washery to JSW Steel, marking the first coal washery asset monetisation under the Ministry of Coal's asset monetisation programme. The handover took place in the presence of senior officials from Bharat Coking Coal Ltd, JSW Steel and JSW Energy. The washery has a capacity of two million tonnes per annum (mn t per annum), and its transfer is intended to introduce private sector practices into coal beneficiation operations. The monetisation is aimed at modernising coal sector assets, improving operational efficiency and enhancing resource utilis..
