of the easiest to use interfaces on the market, hoist speeds – up to a 6:1 speed ratio – can easily be set and saved using slider tabs on the tablet screen; optimum accelerations are automatically calculated accordingly. Upper and lower lift limits, decelerations to slow approach zones, additional overload protection and the like can all be set from on-screen tabs. Hoist status information, including start/stop cycles, motor run time, DC bus voltage, and over-temperature and over-current events and other fault information can be shown as well. The free mobile app stores the last ten faults, noting when they occurred. In the paid ‘Mobile+’ version of the app the last 50 faults are stored. With diagnostic information available instantly problems can be the more rapidly solved; planned and preventative
are smooth. The Lodestar VS also has Swift-Lift, which doubles the lifting speed at loads less than 20% of the rated load, thus halving the hook lifting time and increasing productivity. The hook automatically slows down when approaching a set location, say near the pick-up or drop-off point, which gives more precise control, improves operator safety and protects the load, and the hoist, from damage. Intelli-Connect is an option on all new Lodestar VS models. Intelli-Connect is also available in a retrofit kit for units that are already out in the field. These kits include the wireless operator, mounting bracket, wiring and the hardware needed to install it onto the hoist. Turkish-based manufacturers CMAK, who have offices also in Germany, have an advanced monitoring system called HoistSense+ that transforms any electric hoist or overhead crane into a smart, self-monitoring unit that tracks load, wear, safety status and performance around the clock, giving the real-time data that today is essential in high-intensity industrial production. Their latest upgrade introduces a sub-1GHz (433MHz) wireless module which gives improved signal penetration in industrial buildings and significantly less interference than traditional Wi- Fi; communication range is therefore extended. Installation is simple plug-and-play. Stability and range are claimed as outstanding. With it, new capabilities are possible. Advanced load sharing and multi-hoist synchronisation are just two of them. When two hoists are on a single crane HoistSense+ provides accurate load balancing between them, easing the handling of long or irregular loads. For still more complex lifts it can give equal weight distribution even between four hoists. It can similarly coordinate tandem or quad lifts when the hoists are mounted on separate bridges or gantries on four different cranes, to give synchronised movement over an extended area. There is an UltraSpeed mode for faster lifting under partial loads of up to 25% of SWL. It provides alerts for overload, brake wear and
slack rope. Automated service reminders and monthly performance reports are delivered by email: voltage issues, operator behaviour patterns and abnormal
