The fatal hidden dangers of tower cranes in high-altitude operations
Risk of overloading and overturningTower collapse accidents caused by excessive torque account for 68% of major accidents (mandatory control item in GB 12602-2009).
Blind spot collision out of controlDuring high-altitude hoisting, the field of vision is limited, and the rotation may collide with surrounding structures or high-voltage lines.
Data silo problemParameters such as lifting capacity, amplitude and height are displayed independently, lacking real-time correlation protection.
It is difficult to trace illegal operationsAfter the accident, the operation records cannot be restored and the responsibility definition is ambiguous.
Note: The tower crane accident 90% was caused by torque over-limit, blind zone collision and limit failure (GB 5144-2006).
2. Solution
WTSM-T Tower Crane Intelligent Safety Monitoring System (National Standard Full Certification)
Four-layer protection closed-loop design：
Dynamic interlocking of core parameters→ Lifting capacity + amplitude + height + turning AngleReal-time calculation of actual torque: warning when exceeding 95% and cutting off power when exceeding 105% (in compliance with GB/T 5031-2008).
Three-dimensional anti-collision systemThe laser rangefinder can scan obstacles within the range, with dual response of sound and light alarm and automatic braking (accuracy ±0.5m).
Dual-channel braking redundancyThe main control PLC+ independent safety relay enables emergency shutdown in case of any fault.
Full-process black boxStore over 180 days of operation data and support accident traceability (with a resolution of 0.1 seconds).
3. Core Technologies
Hard-core barriers under the framework of national standards
Multi-sensor fusion algorithm
The lifting capacity sensor (accuracy ±1%) + amplitude encoder (±0.1°) + altimeter (±1cm) are integrated in real time to resist strong wind interference.
AI anti-collision model
Based on the GIS map, a no-entry zone is constructed. When the hook enters a dangerous area with a radius of 10 meters, it automatically decelerates.
Dual power supply disaster recovery design
Dual power supply of 220VAC for civilian use and 24VDC for electric control, maintaining 30-minute safety monitoring even in case of power failure.
4. Core advantages
Six values derived from national standard certification
① All items are covered by national standards
Strictly comply with five types of mandatory standards such as GB 5144/GB 6067.1, and pass the inspection at one time.
② Millisecond-level dual protection
The dual-channel processing of the main control system and independent safety relay results in a braking response of less than 100ms.
③ Intelligent early warning in advance
11 types of risks such as overloading prediction, wind speed exceeding limit, and wire rope hopping are warned 3 seconds in advance.
④ Industrial-grade compatibility
Directly read PLC data (supporting Ethernet /PROFIBUS) and seamlessly integrate with electronic control systems of various brands.
⑤ Judicial traceability
It encrypts and stores over 50,000 operation records and supports third-party authentication and retrieval.
⑥ Simplified operation and maintenance
Remote fault diagnosis +OTA program upgrade, maintenance efficiency improved 70%.
