With increasing awareness of environmental issues in recent years, Sumitomo Continuous Ship Unloader has contributed to zero emission.
We has taken the lead in the field of Continuous Unloading.
Our effort to improve the efficiency of unloading commenced in 1968, culminating in the delivery of our first machine in 1976.
Our line-up includes the Twin-belt type and the Vertical Screw type.
Our full line of Continuous Unloader gives you the freedom to select the optimum machine for you your material to be handled, vessel size and discharge capacity.
High Performance Handling, 3 Modes of Digging
The Sumitomo CSU minimizes unloading time with 3 modes of digging: Horizontal L-mode, Swing-Out Digging Mode and Catenary Bottom Clean-Up Mode. These modes allow our CSU to efficiently unload a wide range of vessel sizes.
The Swing-Out Digging Mode can incline the digging head to a maximum of 35 degrees, in order to reach deep into the ship hold.
The Catenary Bottom Clean-Up Mode allows the buckets to efficiently scoop up the last remaining material, even with the ship is moving from wave action, without damaging the hold bottom.
All main motions of the Sumitomo CSU, except for some secondary motions, are electrically powered. Compared to hydraulically powered CSU, the electrically powered Sumitomo CSU are much easier to maintain and operate.
Guide rails for the bucket chain have been eliminated on the Sumitomo CSU, which prevents excessive load on the digging head, resulting in less wear on the buckets.
High Safety and Reliability
All structural fatigue calculations of the Sumitomo CSU follow stringent JIS standards. During operation, the advanced overload protection system for the bucket elevator minimizes fatigue loads on the structure. The optional Fatigue Life Monitoring System will facilitate fatigue prediction to enhance fatigue life.
The fully enclosed material pathway allows the Sumitomo CSU to eliminate dust and spillage. All major motions are electrically powered, reducing vibration, noise, oil leaks and enables greater energy efficiency.
