How to choose the anti-collision system of the tower crane? In-depth analysis of three mainstream anti-collision technical solutions

In the construction process of modern smart construction sites, cross-operation of multiple tower cranes has become the norm. How to effectively avoid collisions between tower cranes and between tower cranes and obstacles?Anti-collision system for tower craneAs the core safety monitoring device, by monitoring the operation data of the tower crane in real time and calculating the three-dimensional spatial parameters, a “firewall” has been built for construction safety.

Weite (WTAU) has launched three representative models for different models and construction scenarios.Anti-collision system for tower craneplan.

Solution 1: Flat-arm tower crane anti-collision system-radar full-dimensional monitoring

The flat-arm tower crane (Hammerhead Crane) is the most common model on construction sites. In view of its operating characteristics, Weite developedAnti-collision system for tower craneFocus on the dynamic protection of the horizontal plane.

• Technical realization： Install high precision on both sides of the tower arm (big arm)Radar sensor, to achieve a comprehensive scan of the surrounding environment.

• Early warning logic： When the sensor detects that the distance between the tower arm and surrounding objects (such as adjacent tower cranes, building edges) reaches the set safety boundary, the system will automatically issue a sound and light alarm and remind the operator.

• Data interconnection： The monitoring data supports real-time transmission to the large screen of the central control room through a wireless network (4G/5G) to achieve remote supervision.

Solution 2: Boom tower crane anti-collision system-multi-dimensional coordinate real-time protection

The boom of the Luffing Jib Crane can move up and down with variable amplitude, the working space is spherical, and the trajectory is more complex. theAnti-collision system for tower craneAdded spatial calculation of vertical dimensions.

• Technical realization： In addition to the same radar sensor as the flat-arm tower crane, an additional radar sensor is installed at the root of the tower arm.Angle sensor (amplitude sensor).

• Core advantages： By monitoring the pitch angle and horizontal position of the tower boom in real time, the system dynamically restores the actual trajectory of the crane in three-dimensional space, and protects the operation safety of the boom tower crane in the complex lifting process in all directions.

Solution 3: Multi-tower crane collaborative active anti-collision-smart group tower solution

In the complex environment of ”multi-tower group" operations, stand-alone anti-collision can no longer meet safety requirements, and must be introduced.Active anti-collision system。 This system is not only suitable for tower cranes, but also can be extended to a variety of lifting equipment such as gantry cranes and bridge cranes.

• Full parameter perception：

  • Azimuth instrument： Monitor the precise orientation of the tower crane.

  • High precision encoder： Capture the rotation speed and hook height position in real time.

  • QXZ sensor： Detect the pitch angle of the boom.

• Active intervention function： The system pre-sets the coordinates of obstacles (electronic fences) on the construction site. When the boom or crane of the tower crane is close to the no-entry zone or other tower crane，Anti-collision system for tower craneWill triggerActive control, Forcibly stop the operation in the dangerous direction to ensure the absolute safety of hoisting.

• Dock/group versatility： The principle is the same asAnti-collision system for dock crane fleetSimilarly, it is the ultimate solution to the safety problems of large and complex construction sites.

Digital management: remote monitoring and data sharing

modernAnti-collision system for tower craneNo longer an isolated operation, it integrates powerful digital capabilities：

1. Remote access and storage： All historical operation trajectories and alarm records support cloud storage to facilitate accident traceability and safety audit.

2. Wireless large-screen linkage： On-site data is synchronized to the site smart center in real time, and management personnel can monitor the hoisting progress of multiple tower cranes globally in the central control room.

3. Efficient collaboration： Through the remote scheduling function, on-site communication interference is reduced, and the overall coordination efficiency of group tower operations is significantly improved.

Expert advice: How to choose the right system?

chooseAnti-collision system for tower craneWhen, the number of tower cranes on site, the spacing of tower bodies and the complexity of surrounding obstacles need to be considered comprehensively.

• Single operation： It is recommended to choose a radar sensing solution.

• Complex tower operations： It must be equipped with a multi-tower collaborative anti-collision system with “active braking” function.
