Investing in a reliable, accurate, and robust ultrasonic anemometer will take the guesswork out of knowing real-time wind conditions. It also tells you the temperature of the air, the compass heading relative to the device, the moisture borne in the wind, the density of the air, and dew point. The TriSonica Mini uses ultrasonic measurements to tell you exactly how fast the wind is moving-from the lightest breath to a stormy gale-and in what direction it moves: up, down, front, back or sideways. So how can an operator effectively and accurately track the atmospheric changes impacting their work environment? The answer can literally fit in the palm of your hand: the TriSonica Mini Wind & Weather Sensor. This means that a small increase in wind speed can severely threaten the safe performance of a tower crane.” Wind pressure varies as the square of the wind speed, so, as wind speed doubles, the wind pressure increases by a factor of four times. While being able to track wind speed is important, ANSI stresses, “…the primary concern related to the forces that wind exerts on a tower crane’s load is not the speed of the wind, but its pressure. One of the main culprits behind these tragedies was exposure to wind, which caused 23 percent of all accidents.” The American National Standards Institute (ANSI) reports that, “Between 20, there were 1,125 tower crane accidents reported worldwide, resulting in over 780 deaths. The fact is wind is the second most common cause for crane accidents worldwide. It’s a simple but profound statement for crane operators today. It’s great to see that even with small components a big impact can be made to improve safety and situation awareness.Know the wind. In many industrial and heavy duty/building sectors we see the use of 3D printing in small accessories like this. This project is definitely helpful for the application it serves, as it solves a tangible problem that involves usability and safety. To measure the wind Tobias uses a bike tachimeter in line with the main rotor shaft, so he can have a reading from an LCD, possibly even in the crane cockpit by extending the cable for a few meters. The anemometer is mounted on top of the crane, the highest point of the machinery, to avoid air currents and vortexes that normally generate near big structures and buildings. The wind, over a certain threshold, will make the anemometer arms spin. The user can monitor the wind situation in safe distance from the non-hazardous area to. Our device is certified as EX II 2 G EX ib IIB T4 by ATEX approvals for use in hazardous areas zone 1 and zone 2. Anemometer with alarm beacons and buzzer,commanded by 2 adjustable thresholds. Moreover, Scarlet’s WS-E10/WSD-E11 with its water-proof and Explosion-proof features make it capable to hold up to all extreme environment.

The anemometer is composed of a rotor, arms and cups that rotate thanks to an axle on a couple of bearings. ANEMOMETER Intergrated alarms for cranes and output pulse.

He Drew everything on Onshape, a free online CAD drawing tool, exported on STL and sliced as usual in Cura. Tower Crane Anemometer Weather Terminal Door Wind Speed Sensor Aluminum Alloy Cu(mounting Bracket) Test & Measurement Environmental Testers Anemometers. To do so he created a 3D printed anemometer with Red PLA filament. It is usually harder to keep track of wind when you work in a closed hull and you are focused on the task of moving extremely expensive and heay materials, so it made sense to Tobias to ease the measurement of the wind speed. It is obvious at this point that being alert about the wind situation is a major safety concern. The safety limit to operate a crane is 70km/h (around 43 mph or 38 knots).Ĭranes have suffered major damages and even complete failure damaging things and causing injuries or death. He’s also a passionate DIY hobbyist and a 3D printing enthusiast as you will soon discover.Īs any sensible Crane operator knows, wind can be a safety concern for the people around, the buildings surrounding the crane and the operator itself as it can exercise a decent force on the load being lifted and on the crane structure itself. His job is somewhat of a dream for most of the kids: he is a Crane operator! Tobias Innerbichler is from Tyrol, a lovely region in the European Alps.
