Inherent defects and safety challenges of mast cranes
High-risk control of guy ropes8 to 16 guy ropes need to be set up. Manual adjustment is inefficient and uneven force distribution can easily cause overturning (accounting for 35%+ of accident rates).
Dynamic blind spot riskWhen hoisting large components, the field of vision is limited, making it easy to collide with obstacles or misjudge the moment (especially in narrow Spaces).
Low migration efficiencyThe disassembly and reinstallation of the guy ropes take 2 to 3 days, which delays the construction period.
National standard compliance gapMost of the equipment failed to meet the mandatory requirements for real-time monitoring as stipulated in JT/T 1277-2019.
Note: Although mast cranes have a large lifting capacity, they are only limited to specific scenarios due to their poor flexibility. Technical measures are needed to compensate for their shortcomings.
2. Solution
Weite WISP Intelligent Monitoring System (Exclusively designed by the drafting unit of the national standard)
A fully closed-loop protection system：
Intelligent stable control of guy ropesThe high-precision force measurement ring monitors the tension of each rope in real time. When the deviation exceeds 15%, an audible and visual alarm is triggered. The tilt sensor is linked to calculate the balance state of the mast to prevent the risk of foundation settlement.
Three-dimensional job protectionThe laser rangefinder can scan obstacles within a radius of 20 meters (with an accuracy of ±10cm). The main/auxiliary hook independent overload cut-off module, with dual-channel guarantee.
Ultra-fast relocation and loading technologyPre-integrated sensor group, disassembled for reuse without calibration (migration time < 4 hours).
National standard data cloud archivingThe operation records are encrypted and stored for more than 5 years, meeting the inspection requirements of JT/T 1277-2019.
3. Core technology
The three technical barriers under the framework of national standards
Dynamic load compensation algorithm
Real-time calibration of inclination-moment based on ANSYS model, resistant to strong wind interference (accuracy 99.5%).
Multi-rope cooperative control system
16-channel parallel cable tension analysis, generating heat maps to warn of imbalance risks.
Contactless operation and maintenance of the kernel
OTA remote program upgrade, automatic fault diagnosis and push repair solutions.
4. Core advantages
The seven core competencies of micro and Special systems
① National standard compliance certification
It fully complies with the requirements of "JT/T 1277-2019", independently records 48 parameters and displays them in real time.
② Full interface compatibility
It is standardly equipped with passive switch quantities, 4-20mA analog quantities, and pulse interfaces, and supports Modbus/Profibus expansion.
③ Judicial traceability
The cloud stores operation records, and the background analyzes the compliance of operations (with an accuracy of 0.1 seconds).
④ Full-domain visual management
Remotely view the GPS location of the equipment and real-time working condition data (4G transparent transmission).
⑤ Predictive Protection
Warn of common faults (such as wire rope overload) and save the fault feature library.
⑥ Digital operation and maintenance
Remotely repair system malfunctions and manage historical operation reports.
⑦ Seamless integration with PLC
Read the PLC data directly and display it dynamically on the monitoring terminal.
