Digger is a ship unloader with unique performance. It was designed and optimized for bulk cargo handling: coal and other raw materials. The advantage of the construction is the intelligent interaction of the main and auxiliary running trolleys with support of pre-stressed rope system. This feature makes possible to transfer more than 3,000 tons per hour. Such power throughout the working shift is conditioned by the use of modern technology: automation of the pendulum distribution and control of the programmed coordinate, complemented by progressive safety system SIS. Digger is always designed individually, including transportation conditions, dust protection and infrastructure requirements.
