Saudi Arabian contractor Rowad al Riyadh has rented two Wolff tower cranes to help build a new mosque in the centre of Riyadh.
The two cranes being used are: a Wolff 6015.8 Clear with a hook height of 51 metres, a jib radius of 60 metres, a lifting capacity of eight tonnes; and a Wolff 7532.12 Cross with a hook height of 41.6 metres, a 70-metre jib radius, and a lifting capacity of 12 tonnes. Both cranes have been on site since March 2025.
According to Wolffkran due to the construction site’s location the job requires extensive and detailed planning as it is located by the busy Abdullah Road and next to a metro station. The placing of the large, prefabricated facade elements and a complex roof design also requiring precise positioning.
The cranes need to utilise their maximum jib lengths in order to cover all areas of the construction site which is around 10,000 square metres in size.
The climate also presents challenges, says Wolffkran, due to heat, dust and afternoon storms. “As a result, many of the lifting operations are performed in the early morning or late afternoon hours for safety reasons, if the weather conditions are stable and traffic and pedestrian flows are low”, explains Tariq Al-Sawaie, managing director Wolffkran Saudi Arabia.
The cranes are equipped with anti-collision systems and Wolffkran’s Wolff Link technology. Wolff Link allows live activity monitoring and real-time alerts in case of critical operating conditions.
Early as in the planning phase the Wolffkran team conducted reach studies, defined safety zones, and adjusted jib and hook positions to enable maximum construction site coverage while minimally impacting public areas.
The cranes are expected to remain on site until the fourth quarter of 2026. Once completed the Sheikh Saleh Al-Rajhi Mosque will occupy an area of around 5,300 square metres, providing room for about 2,300 worshipers. This is the first mosque project on which Wolffkran has worked with Rowad al Riyadh.
