Tower cranes are widely used on many construction sites. Tower‑crane operation is high‑altitude hazardous work. Accidents such as overturning may easily lead to severe consequences. To enhance the safety system for tower cranes, it is essential to implement safety monitoring of full‑range tower‑crane operating parameters. The installation of our monitoring system can well satisfy on‑site construction requirements and make tower‑crane operations much safer.

Functions of the Tower‑crane Monitoring System

1. Data CollectionReal‑time collection of parameters including hook height, trolley travel distance, ambient wind speed, real‑time lifting weight, jib rotation angle, tower‑body inclination, torque and other relevant data.
2. Data DisplayThe main‑unit display screen presents monitoring data in real time. Tower‑crane operators can keep track of the working status at any time. Historical data is recorded, and system‑monitored data can be stored for several years.
3. Data UploadAdopting GPRS technology, powerful database capabilities and a complete remote monitoring and management platform to realize data upload. Managers can gain a clear overview of tower‑crane working conditions.
4. Anti‑collision for Multiple Tower CranesWhen multiple tower cranes operate within the same area, the system automatically identifies surrounding tower cranes and their working status via wireless communication modules. It calculates collision risks with adjacent units. Alarms will be triggered promptly and corresponding responses will be activated if collision hazards are detected.
5. Visualized OperationAn embedded intelligent video system is mounted on the trolley of the tower‑crane jib. Embedded high‑definition cameras capture dynamic information within the hoisting zone. Footage is transmitted wirelessly to visual smart terminals such as computers, mobile phones and tablets for real‑time display, realizing full‑process visualized operation. In addition, videos captured by cameras in the operator cabin and on the jib trolley can be transmitted back to the project‑department monitoring center for long‑term storage and playback. In case of accidents or disputes, evidence is available for clear liability identification.

To sum up, the tower‑crane monitoring system is designed to collect real‑time tower‑crane data, predict potential hazards in advance and reduce losses of personnel and equipment. Covering the full lifecycle of tower cranes from installation to complete dismantling, this integrated system applies information‑based technologies to record the whole operation process, prevent overturning during installation and dismantling, and avoid collisions among multiple tower cranes. By real‑time data monitoring throughout the equipment lifecycle, it achieves the fundamental goal of work‑site safety and delivers safer tower‑crane operations.
