STOCKPILE MANAGEMENT 62 E&MJ • DECEMBER 2018 Tsurumi Manufacturing Co., Ltd. manufactures, supplies and sells pumps and related equipment. Submersible pumps are key prod- ucts. Since its foundation in 1924 in Japan, Tsurumi has driven the industry as a leading company in submersible pump fields. For the mining industry, we have pumps equipped with the impeller, casing, motor frame, outer cover, strainer stand and flange made of 316 stainless steel — all parts that come in con- tact with fluids are stainless steel. This is particularly important because runoff and discharge from mines and quarries in recent years has caused pollution in many countries. In fact, more than 40% of the discharge from mining operations is highly acidic with a pH value less than 4 and is requiring more and more operators to seek out drainage pumps to treat that wastewater. This is where Tsurumi can be of service, as we determinedly develop all stainless steel pumps to serve these needs. All Stainless steel pumps can handle chemical fluids of low pH value (e.g., corrosive acidic fluid). They also stand up to drainage that contains abrasive materials. In other words, they are durably designed and built for severe environments that cause aluminum and cast-iron pumps to break down in a matter of weeks if not days. COMPANY PROFILE-PAID ADVERTISEMENT Tsurumi Submersible All Stainless Steel Dewatering Pumps Tsurumi Manufacturing Co., Ltd. Moreover, all stainless steel pumps are applicable not only to mines and quarries but also to a wide range of fields such as waste- water treatment. Tsurumi also offers seawater-resistant pumps that employ unique technologies. We are here to serve you, so contact us no matter what your need. to be seen, but even major OEMs like Hita- chi, Komatsu and Caterpillar are spending money to establish a foothold in the sector, implementing drone-based hardware, soft- ware and services to add another dimen- sion to their connected-worksite scenarios Dominant players in the sector continue to offer and expand a variety of solutions that include drone models designed for profes- sional and "prosumer" users, tailored drone mapping and surveying software packages, and even fully automated drone operation, service and data analysis. Among the most recent developments, Propeller Aero, a cloud-based drone ana- lytics company, is partnering with drone builder DJI to create the Propeller PPK Solution based on DJI's new Phantom 4 RTK drone. Propeller also announced the startup of a partnership with Komatsu America in August, starting with a focus on construction-site management, but with the mining industry in mind as well. Propeller said its PPK Solution is a fully integrated software and hardware system that reliably provides photogrammetric model outputs in geodetic, projected or local coordinate systems. It provides ac- curacy of 3 cm from independent check- points across small and large survey areas (checkpoints up to 1 km from GCPs). To capture surveys of this accuracy, all that is needed is one "smart" control point on the ground, over a known point if working in local coordinates. Propeller claims its PPK Solution has been shown to reduce the time required to complete a drone survey by 70% compared with a traditional work- flow using multiple GCPs across a worksite. DJI launched the Phantom 4 RTK quad- copter in mid-October, featuring an RTK module integrated directly into the drone, providing real-time, centimeter-level posi- tioning data for improved absolute accu- racy on image metadata. Non-RTK drones require multiple ground control points per square kilometer, which take several hours to place. The DJI Phantom 4 RTK has a centimeter-accurate RTK navigation posi- tioning system and a high-performance im- aging system, and potentially reduces the number of GCPs needed to zero. Sitting just beneath the RTK receiver on the drone is a redundant GNSS module to maintain flight stability in signal-poor areas. An RTK module is integrated directly into DJI's new Phantom 4 RTK drone, providing real-time, centimeter-level positioning data for improved absolute accuracy on image metadata. The drone's new TimeSync feature continually aligns the flight controller, camera and RTK module.
