A wind speed sensor or anemometer plays an important role in measuring wind speed for crane safety. The risks associated with wind are often underestimated by the public. To ensure workforce safety and regulatory compliance on cranes as well as other industries, health and safety authority around the world such as OSHA sets standard regulation regarding wind speed. Anemometer has become a must-have tool for every crane operation, from tower crane to mobile crane.
For safe and smooth lifting operations, it is recommended to have accurate and detailed wind data readings. To get a reliable wind speed and sometimes also wind direction (depending on anemometer type) data measurement, you can use a handheld anemometer which is a portable wind data display. The other option is to apply an online wind monitoring system to monitor real-time wind conditions from smart devices such as PCs, laptop, tablet, and smart phone.
Which one to choose? handheld anemometer or online wind monitoring? Here is the breakdown of each type. To understand better, let’s first have a look.

Accuracy | The accuracy can vary greatly from device to device.locations. Recommended accuracy +/- 1-3 % for cups anemometer. | The accuracy can vary greatly from device to device. Recommended accuracy +/- 1-3 % for cups anemometer. |
Placement | Wireless=Cable free, can be placed anywhere according to needs. Usually placed at the boom tip of crane. For tower crane, a number of anemometers will be used and placed at different height levels. | Wireless=Cable free, can be placed anywhere according to needs.

Distance Transmission | Long range (±400m) | Long range (±500-1300m) |
Remote monitoring | No, only allows on-site monitoring. | Yes, data can be monitored on site or remotely at any time using a smart device(tablet, smart phone, or laptop) and internet connection. |
Alarm Warning for High Wind Speed | Yes, programmable and built-in alarm. | Yes, programmable and built-in alarm. |
Multiple Users | No, only user with device can receive data readings. | Yes, multiple users can receive synchronized real-time wind data on monitor display and web portal. |
Wind Conditions Reports | Only send real-time wind data to device. No auto report generation. | Auto report generation, sends and stores data to managers via cloud-based system. Data is accessible 24/7. |
Since both type of handheld anemometer and online wind monitoring are cable free, in general they come in handy and easy to be moved around. If you work in complex project where multiple people needs to get wind data readings simultaneously, it is recommended to opt for online wind monitoring system. However, if you only need a reliable data reading without auto report generation and multiple users access, then a handheld anemometer will fulfill your needs.
So between handheld anemometer and online wind monitoring, which one will you choose?
Each anemometer is designed to meet certain needs, all you need to do is to first understand what kind of anemometer will satisfy your own needs, then choose the one which suits you best.We hope the above table help you to understand better and smoothen your decision-making process, but if you still unsure and have some questions in mind, feel free to talk with us, we would be more than happy to discuss your needs.
