20 SANY cranes including 4 truck cranes and 16 crawler cranes were used to undertake the construction of Ibese cement plant in Nigeria.
A total of 20 SANY cranes including 4 truck cranes and 16 crawler cranes together with several concrete pumps and mixers were used to undertake the construction of Ibese cement plant, a major project of Dangote Group from 2008 to 2015.
Dangote Cement is West Africa's leading cement producer with 19 million tonnes of capacity at plants in Obajana, Ibese and Gboko in Nigeria. The newly built Ibese factory, located in Ogun state about 120km north-west of the Capital Lagos, has 6mt capacity.
The cranes fleet comprised of one 250t crawler crane, one 150t crawler crane, two 25t truck cranes, two 50t truck cranes, and fourteen 50t crawler cranes are mainly responsible for the installation of four 6000t cement production lines in Ibese cement plant project. Each model was put to good use on the worksite.
SANY crawler cranes adopt a variety of leading technologies to ensure easy transportation, quick set up, strong load capacity, safe and reliable operation. The SCC500 50t crawler cranes are equipped with a 13m-52m long lattice boom, 15.25m fixed jib, and 28m luffing jib, delivering maximum lifting capacity of 50t×3.7m, 185t·m. the maximum transportation width of the crane machine is only 3.3m as its track frame on both sides is telescopic. Besides, the telescopic crawler can be expanded / retracted to provide both stability and flexibility on site. The 150t crawler crane and 250t crawler cranes are mainly used to lift the loads much heavier such as concrete slabs, steel frames, large beam etc.
The truck cranes are more flexible in action. With crane width of 2.5m, turning diameter of 22.5m, and maximum gradeability of 40%, the 4-axle chassis STC500C truck crane provides great mobility on site. Meanwhile, the 50t truck crane is equipped with a five-section U-shaped boom that fully extended to 43.5m long, and a 16m jib. The maximum lifting height including jib is up to 59.2m.
Under such a complex working condition, the crane machines from SANY are designed for a safe operation, guaranteed by several safety technologies and devices including the load moment limiter with comprehensive intelligent protection system, tipping over early warning technologies, CAN- bus full-digital network control, emergency stop button, lightning protection.
