A key power transmission line project in West Asia is steadily advancing. The project focuses on upgrading the regional power transmission network, with the core construction work being the pouring of pile foundations for power towers along the entire line. The tower positions are scattered and cover a wide area, compounded by a short desert construction window and a tight schedule, resulting in enormous overall construction pressure. The project relies entirely on open-air field operations, placing extremely high demands on the all-weather capability, stability, and adaptability of construction equipment—making it a typical infrastructure project under harsh desert conditions.

The core difficulties of this construction are concentrated in the special desert geology and the shortcomings of field operations. The site is dominated by alternating layers of aeolian sand and gravel, interspersed with dense cemented sand layers, making hole walls highly prone to instability during drilling. Ordinary rotary drilling rigs lack sufficient power and penetrate slowly, seriously slowing construction progress. At the same time, frequent local sandstorms, extreme day-night temperature differences, rudimentary field maintenance conditions, and difficult equipment relocation all directly lead to schedule delays. After on-site comparison of multiple equipment types, the contractor ultimately selected the XCMG XR240E rotary drilling rig, whose high-torque power, high stability, dedicated desert-condition adaptability, and comprehensive overseas localized service became the core advantages for overcoming the construction challenges.

Targeting the project's pain points, the XCMG XR240E is precisely adapted for efficient tackling of challenges. The equipment is equipped with a 240kN·m high-torque power system, easily breaking through the drilling resistance of gravel strata and avoiding hole collapse, achieving excellent hole quality. On-site measured data is impressive: for standard power tower pile foundations with 1200mm diameter and 18m depth, the equipment can stably complete pile foundation construction in a single day, operating around the clock in shifts without failure or downtime, greatly shortening the single-pile operation cycle

The equipment is specially adapted to desert conditions with strong compatibility: it accommodates local diesel fuel, and the enlarged cooling assembly resists high-temperature exposure, preventing high-temperature breakdowns. In addition, the patented single-row rope winch, reinforced structural components, and dust-proof, high-temperature-resistant pipe design effectively reduce equipment wear and maintenance frequency

The on-site project manager highly praised the XCMG equipment:

The XCMG XR240E perfectly adapts to the local desert geology, with hole-forming efficiency exceeding expectations, extremely low equipment failure rates, and minimal field maintenance pressure. It has steadily guaranteed the progress of power tower pile foundation construction throughout, making it an excellent piece of equipment for desert power transmission infrastructure.At present, the project's pile foundation construction is steadily progressing, laying a solid foundation for the on-schedule completion of the entire transmission line and the improvement of the regional power grid. The XCMG XR240E's hard-core strength of high efficiency and strong adaptability has created an integrated solution for overseas desert power tower pile foundation construction, precisely solving the construction challenges of extreme working conditions. In the future, XCMG will continue to deepen its presence in overseas infrastructure markets, iterate and optimize the performance of piling equipment, and continue to empower global power infrastructure upgrades with high-quality intelligent manufacturing equipment, polishing the overseas image of Made in China.
