JSW Steel Limited - Dolvi
JSW Steel Ltd is an Indian multinational steel producer. For their steel plant located at Dolvi near Mumbai JSW was using mobile harbour crane to handle cargo and was facing issue with reliability and high operation cost.
The operation was to unload from barges and feed it on to hoppers of above 10 meter height. Sennebogen offered 2 units of 880EQ crawler machine with 7 meter pylon, 430 kW electric motor, boomstick with 30 meter outreach, 6cbm clamshell grab for iron ore, limestone, pellets and dolomite handling and 14cmb clamshell grab for handling coal.
The two Sennebogen machines were chosen for their simplicity in maintenance & ability to operate non-stop in hot & dusty condition with fast cycle time for cargo handling. The machines are in operation for approximately 20 hours per day & the JSW machine operators had no difficulties in adjusting to the new machines.
The JSW management decided to opt for electric motor engine rather than diesel motor engine which resulted in reduction of Operation & Maintenance cost by more than 30 percent vis-à-vis its diesel engine model. The 880EQ has no complicated electronics and is a hydraulic material handling machine making it very operator friendly. The counterweights of the 880EQ are equally distributed so as to attain the center of gravity in such a way that the machine would have uniform load carrying capacity in complete 360 degrees. This means that only a small amount of energy is needed to drive the equipment - even when large operating ranges and heavy loads are involved.
Sennebogen 880EQ is in demand when there is a large work area to be covered and is ideally suited to the challenging work of unloading bulk cargo and general cargo from ships up to Handymax size.
These two giant units of Sennebogen are in operation since 2014.
