NHI spreader has advantages of simple structure, good movability, easy installation, operation and maintenance and stable and reliable service. The machine has a wind range of models with capacities ranging from 1500t/h to 10000t/h, length ranging from 30m to 300m and equipment working weight varying from 50 tons to 4000 tons. To suit the applications in special conditions, a mobile cross-pit spreader system is developed with discharging boom length as 200 meters. The spreaders of specific models and sizes can also be tailor-engineered for the application and built to order to meet the requirement of the client and the site conditions.
