How does the visual monitoring of anti-collision and anti-overturning for truck cranes make danger nowhere to hide

In the narrow corners of construction sites, above the city where high-voltage lines are densely packed, and on the mountain peaks where fierce winds howl - truck cranes (truck hoists) are like steel mantises, exerting tremendous power in a small space. The modern anti-collision and anti-overturning visual monitoring system is precisely what enables these "high-altitude dancers" to perform precisely at the edge of dangerGuardian of Life. When the boom rotates just 3 meters away from the high-voltage line and the outriggers slightly sag on the soft foundation, this system builds a safety barrier at a life-and-death speed of 0.3 seconds.

Double Danger: The Fatal Moment for Truck Cranes

Truck crane operations are like dancing on the tip of a knife, with two major risks always lurking:

Overturning trap
At a construction site in Zhengzhou, when a 32-ton truck crane was fully extended, it suddenly encountered a subsidence of the foundation.

• The instantaneous imbalance of outrigger pressure is greater than 40%

• The entire machine is tilted at 4.8° (with a critical point of 5°).

• The monitoring system completes the process within 0.8 seconds: alarm → lock arm → start auxiliary support
  Prevent a 2-ton prefabricated slab from falling from a height of 15 meters

Collision crisis
A thrilling scene at a Shenzhen Metro construction site:

• The boom is only 2.3 meters away from the 10-kilovolt high-voltage line

• The driver's field of vision was blocked by the building

• Millimeter-wave radar can detect danger 15 meters in advance

• Automatically cut off the rotary power supply and issue a shrill alarm

According to statistics, the 70% truck crane accident was caused by the combined effect of overturning and collision

Technical Deconstruction: How does the Triple Protection Net Work

1️⃣ Overturning protection: Sensing the pulse of the Earth

• Outrigger pressure matrix：
  Each outrigger is equipped with 8 sensors to monitor pressure changes in real time
  The accuracy reaches 0.1 tons, equivalent to detecting the weight difference of a bucket of water.

• Three-dimensional attitude instrument：
  0.01° tilt perception +GNSS displacement monitoring

• Intelligent decision-making：
  When the pressure difference is greater than 15% or the tilt is greater than 3°, the range of motion will be automatically limited

Practical case studies：
A wind farm in Qinghai suddenly encountered a crosswind of force 8. The system automatically:

1. Calculate the wind load moment

2. Retract the boom to a safe range

3. Lowering the counterweight blocks increases stability

2️⃣ Collision protection: Transparency of space

• Lidar scanning：
  Build a three-dimensional protective net with a radius of 30 meters (accuracy ±2cm)

• High-voltage electricity early warning：
  The non-contact electric field sensor detects cables within 50 meters

• Three-level response mechanism：
  10-meter sound and light warning → 5-meter deceleration → 2-meter emergency stop

The speed of life and death：
At a construction site in Guangzhou, when the hook was only 1.7 meters away from the top of the underground garage, the system automatically stopped lifting - the driver could not see the obstacles above at all.

3️⃣ Visualization hub: The driver's third eye

The smart terminal in the driver's cabin is like a transparent mirror:

• Panoramic splicing picture：
  It integrates six cameras to achieve 360° coverage without blind spots

• Dynamic safe zone display：
  Real-time marking of the sweeping range of the boom (automatically changing with amplitude)

• Risk heat map：
  Mark the risk level with red/yellow/green

Zoomlion's actual test shows that drivers can reduce operational errors in the blind spots of 80% through the screen

Policy pressure: The safety red line continues to tighten

Upgrading regulations promotes the popularization of technology

• The new national standard in 2023：
  Torque limiters must be installed on truck cranes with a capacity of over 12 tons

• Mandatory Clause 2024：
  New requirements for outrigger pressure monitoring and obstacle early warning have been added

• Eu CE certification：
  It needs to pass the EN 13000 anti-overturning test

Selection core: Five key indicators

Five essential capabilities to verify when choosing a system:

1. Fully integrated perceptionThe outrigger pressure, three-dimensional posture and spatial scanning are integrated into one

2. Millisecond-level responseFrom risk identification to execution, it takes no more than 0.3 seconds (1.5 seconds for human response).

3. Intelligent risk reductionIt not only alarms but also automatically switches to safe mode

4. Extreme adaptationStable operation: -30℃ cold zone /50℃ high temperature

5. Intuitive displayReal-time rendering of risk heat maps on a 10-inch screen

Intelligent Evolution: A Revolution from Defense to Anticipation

Cutting-edge technologies are reshaping the boundaries of security:

• Digital rehearsal system：
  Input site parameters to predict hoisting collision points (After application by Shanghai Construction Group, the number of accidents decreased by 60%)

• AR X-ray eye：
  Drivers wearing helmets can "see through" buildings (pilot project by China Railway Construction Corporation)

• Group protection net：
  The data of multiple truck cranes are interconnected to automatically avoid the risk of cross-operation

The guardian of life in a small space

When the truck crane bypasses the dense high-voltage power line network in the busy downtown area, and when it stabilizes the swaying steel box girder at the construction site of the cross-river bridge -Behind every precise avoidance lies 500 environmental scans per second, a 0.01° tilt perception, and a spatial insight more acute than that of an eagle's eye。

According to statistics from the Ministry of Emergency Management, the accident rate of truck cranes equipped with intelligent monitoring systems has decreased by 761 tons over the past three years. But more astonishing than the data is that the young operators at the Beijing CBD construction site are no longer sweating profusely, the wind power installation teams on the Qinghai-Xizang Plateau dare to challenge higher wind speeds, and the elderly at the renovation site of old residential areas walk safely under the cranes.

Truck crane monitoring systemNo longer relying on the "intuitive mysticism" of the master, every extension of its boom is calibrated by algorithms, and every landing of its outriggers is protected by data. The anti-collision and anti-overturning system for truck cranes is redefining high-altitude safetyLet the most dangerous dance steps be elegant and composed, and let the most limited space still be handled with ease。
