Page 36 of 55 June 2019 • 35 FEATURE BAUMA 2019 perform their normal operations without loss of productivity and free of emissions. The manufacturer's zero-emission series includes a wheel loader, track and wheel dumper and the two new mini-excavators, along with battery-powered rammer, plates and, in future, internal vibrator systems for concrete consolidation. While not entirely operated by electricity, CIFA showcased its current version Energya electric hybrid concrete delivery equipment. They tout that their rear discharge concrete mixer, concrete pump, and shotcrete sprayer delivers greater fuel efficiency and less emis- sions. The mixer was unveiled three years ago and continues to be upgraded in performance. Producers using the Energya 9 mixer can expect up to a 30 per- cent equivalent fuel savings under typical operating conditions. The chassis engine can be shut off during drum loading at the batch plant, unloading at the job site, and back in the yard. Electric power is used for drum rotation and is driven by an electric induction motor fueled by a lithium ion battery. Charging times vary depending on method: An hour using high speed plug-in or about eight hours from any 220v industrial outlet. Producers who have used the Energya 9 report an additional oper- ational benefit. The unit is much quieter during the batching and unloading process. This allows easier communication and increased job safety. CONNECTING THE WORK SITE Digitization is the process of changing data from analog to digital form. When this transformation is successful, the outcome isn't any different than its original form but provides greater transfer of data. Paperless receipts for concrete deliveries are a good example of the concept. At bauma 2019, several non-traditional players offered new tech- nologies to use digitization to bring about greater job sight efficiency. PERI, a formwork manufacturer, now offers a concrete maturity mon- itoring system. Its InSite Construction technology measures fresh concrete's consistency and temperature while in the form. The system provides guidance on formwork pressure and distribution of the con- crete in the formwork during placement. Doka, also a formwork manufacturer, unveiled a mobile app designed to optimize the entire concrete order and delivery process. The Smart-Pouring system monitors key order details such as required compressive strength, delivery time, delivery site, and placement method. The app follows the order through batching into the assigned concrete truck. The system then monitors the delivery using Blue- tooth beacons to ensure that the concrete ordered is placed in the correct location. Giatec, a Toronto-based provider of concrete quality control tech- nology, upped the concept of digitization with its unveiling of Roxi. Using a data-mining approach called machine mining, this software detects anomalies at various stages of the concrete life-cycle. Roxi was built specifically for Giatec's SmartRock wireless concrete sensor as it compares current sensor conditions to past measurements stored in the Giatec database. Roxi can detect any subtle variance from what should be the norm. The technology alerts users of a potential problem during production, delivery, placement, and hardening at a speed that is nearly impossible for humans. Digitization has also improved the operation of truck cranes. Pal- finger, an Austrian manufacturer of lifting devices unveiled their digital philosophy at bauma 2019. Their Smart Boom Control is a digital boom tip controller for loader cranes. A specially manufac- turer-developed electronic control system instantly calculates the necessary movement combination using its position and pressure sensors. The software and operator work as a team to comply with equipment parameters as provided in an operating manual load chart. Palfinger also added a second level of digitization with an enhanced stability control system feature. HPSC-Plus LOAD is a load detection system that uses inclination as an additional parameter for stability.
