The Sheikh Saleh Al-Rajhi Mosque, a new architectural and spiritual landmark rising along the bustling King Abdullah Road in central Riyadh, is being constructed with the help of two high-performance WOLFF tower cranes. The project, led by contractor Rowad Al Riyadh, involves intricate planning due to its prime location and complex structural requirements.
To meet the demanding site conditions, Rowad Al Riyadh has deployed a WOLFF 6015.8 Clear and a WOLFF 7532.12 Cross. The WOLFF 6015.8 Clear features a hook height of 51 meters, a jib radius of 60 meters, and a maximum lifting capacity of 8 tons, while the WOLFF 7532.12 Cross offers a hook height of 41.6 meters, a 70-meter jib radius, and a 12-ton lifting capacity. Both cranes have been operating on-site since March 2025.
Spanning approximately 10,000 square meters, the mosque’s construction involves lifting large prefabricated façade panels and a complex roof structure, demanding exceptional precision and maximum reach coverage. The site’s proximity to King Abdullah Road and a metro station presents significant logistical challenges, requiring careful coordination and scheduling.
“The region’s high temperatures, dust, and occasional afternoon storms make crane operations highly time-sensitive,” explained Tariq Al-Sawaie, Managing Director, Wolffkran Ltd., Saudi Arabia. “To ensure safety and efficiency, most heavy lifts are conducted during early morning or late afternoon hours when conditions are most stable.”
Both cranes are equipped with anti-collision systems and WOLFF Link technology. The anti-collision system automatically slows or stops crane movement when obstacles or nearby cranes are detected, while WOLFF Link provides real-time activity monitoring and alerts for critical operational conditions.
During the planning phase, the Wolffkran engineering team conducted detailed reach and safety studies, optimizing jib positions and defining safety zones to ensure full site coverage with minimal disruption to surrounding public areas.
With the project scheduled for completion in the fourth quarter of 2026, the WOLFF cranes are playing a vital role in delivering one of Riyadh’s most significant new religious and community landmarks — a symbol of precision engineering and architectural excellence.
