Harsh weather adds risk to lifting operations, and quick action may be needed to prevent accidents. To manage risk, the first step is knowing the exact wind conditions at all times. Based on crane specifications, operators and project managers can decide if a lift can proceed safely.
Having accurate wind data is important, but construction firms cannot ignore the role of human interpretation. Contractors need to ensure that crane operators, project managers and other staff members are provided with exactly the same data. Otherwise, they may reach different conclusions based on measurements from different sources.
Sword Construction required an accurate and reliable wind monitoring solution for the Devonshire Dock Hall expansion, where they used two Wolffkran luffing cranes. The facility is owned by BAE Systems, and the expansion will be used to assemble Royal Navy submarines.
Eduardo Estelles, Managing Director of UK-based Windcrane, will be speaking at the International Tower Cranes (ITC) conference on 2 December to highlight new approaches to the use of crane wind speed data, providing benefits for the entire supply chain, from crane rental companies to contractors and clients.
Why is the wind speed sometimes different on one or two of my cranes when they are all on the same site and within close proximity. The max (gust) values vary above and below each other. Often they are similar, but occasionally there are large differences, especially on days of high wind speeds like on Oct 31st. In the chart above we have one crane measuring a wind gust of 42.4mph and another crane measuring 27.2mph.
Dealing with weather-related claims in construction contracts and Extension of Time using site specific wind data at crane height. Weather is a critical factor in construction design, planning and execution has among the most varied and far-reaching effects on project outcome. It is one of the most frequent and harmful causes of project delays and weather claims are a frequent cause of dispute between contractors and owners. These disputes can escalate into legal action, extended delays and further economic losses.
BMUs are vulnerable to high winds and building managers must ensure safe working conditions for cleaning crews. Weather forecasts provide a general idea of what to expect but only a wind monitoring system can track outdoor conditions in real time. When a BMU is equipped with a wind monitoring system, it can detect the early warning signs of high wind and turbulence. This way, building managers can suspend any cleaning or maintenance activities before the wind threatens the crew.
Windcrane telematics wind monitoring relies on the real specific location and height to measure accurate wind data for construction cranes. Providing downtime wind reports and forecast from the exact crane wind speed measurements to justify a delay due to harsh weather conditions.
By developing and utilising the latest digital tools, we can receive crucial benefits like improved data output and greater connectivity between areas. Therefore, digital transformation is something that every business in the construction sector needs to be aware of. No more taking unnecessary risks, you can now adopt useful technology to evolve your business in a positive way.
Wind is the biggest cause of delays and downtime on a construction site and is becoming more erratic every year. For safe and successful lifting operations, it is recommended to have accurate and detailed wind forecasts suitable for your project to better plan your daily and weekly lifting. To measure the speed of wind an anemometer or wind speed sensor device is required.
We tend to think about wind mostly during crane operations, however there’s another side to it and it is when the cranes are parked or out of service. The news this week from Vertikal brought two stories of two crawler cranes collapsing due to wind gust and probably out of service.
To describe the wind in a specific site, you must know both its speed and direction. An anemometer is a weather instrument that measures wind speed, and its direction can be determined with a wind vane. Since wind speed and direction are closely related, weather monitoring systems normally include both instruments.
Construction is often perceived as a “traditional” industry, not commonly associated with modern information technologies or cloud connected services (IoT). However, the tools and equipment used in the construction process have experienced constant evolution over the past decades.
Wind monitoring is key during all life cycle stages of a bridge, from design and construction to operation and maintenance. Bridges are typically exposed to strong wind currents hitting them perpendicularly, and their sheer size results in very high mechanical loads induced by the wind. Even if a bridge is properly des
Being a construction manager involves taking quick decisions and reacting to unpredictable situations. When determining if weather conditions are suitable for construction work, there are many factors to consider: Preventing damage to property and construction equipment Ensuring safe working conditions Rescheduling mat
Anybody working in the construction industry knows that working at height is one of the most dangerous activities, with statistics showing that most cases of fatal injury or severe injury are as a result of a fall from height.

Tower cranes are exposed to a vast amount of hazards with one of the main hazards being wind. Between 2000 and 2010, there were 1125 tower crane accidents reported worldwide, resulting in over 780 deaths.
