Gantry crane safety monitoring system

1. Introduction and purpose

Model: WTSM-A-06
The gantry crane safety monitoring and management system is designed and manufactured for cranes in the shipbuilding and repair industryEnhanced security monitoring equipment. The system is specifically designed for the construction and repair of cranes in shipsLong-term operation, frequent vibration, high temperature, and high dustOptimized for extreme working conditions, it provides comprehensive and reliable safety monitoring and management functions. The core functions include operation status recording, in-depth data analysis, fault diagnosis and early warning of the lifespan of key components, meeting the requirementsNational Standard GB/T 28264-2017 "Crane Safety Monitoring and Management SystemRequirements.

2. Main application scenarios

Specifically designed for unloading and handling industries such as port terminals and shipyards
- It is applicable to large lifting equipment such as gantry cranes and portal cranes in shipyards.
- RegardingHigh temperature, high dust, continuous vibrationEnvironmental protection design is strengthened to ensure the stable operation of the system under harsh working conditions.

3. Relevant configuration

List of core acquisition modules
① Lifting capacity sensor (needs to be compatible with overload limiter signal output)
② Absolute encoder (lifting/lowering height monitoring)
③ Absolute encoder (Large/Small car travel monitoring)
④ Wind speed sensor (automatically triggers shutdown protection)
⑤ PLC/ Operation Instruction Acquisition Module (linkage console or operation button)
⑥ Lifting brake status sensor
⑦ Run the interlock state collection module
⑧ Wind-resistant and anti-slip device sensors (rail clamps, anchoring states, etc.)
> noteEquipment without a signal output device needs to be upgraded or equipped with corresponding sensors.

4. Core Functions and performance features

Intelligent monitoring and analysis
– Hook slip monitoring and early warningReal-time diagnosis of abnormal lifting brakes.
– Fault logic diagnosisAutomatically analyze and control the root cause of faults.
– Life expectancy warningPrediction of the remaining life of key components (such as brakes).

High-reliability design
– Multi-environmental adaptabilityHigh-temperature resistant, dust-proof and vibration-resistant structure.
– Real-time data deep processingBeyond the basic recording function, it provides decision support.

Compliance guarantee
- Fully compliantGB/T 28264-2017National standard monitoring requirements.

5. Applicable Specifications

– GB 12602-1990Safety Technical Specification for Overload Protection Devices of Lifting Machinery
– GB 6067.1Safety Regulations for Lifting Machinery
– GB/T 28264-2017"Safety Monitoring and Management System for Lifting Machinery"

6. Instructions for Data collection and processing

Monitoring items                           Implementation method                         Functional value
The overload limiter for lifting capacity collects signals for immediate protection in case of overload. Devices that do not output signals need to be replaced
The absolute type encoder for lifting/lowering height can keep track of the hook position in real time. Unmonitored equipment needs to be installed
Large/car schedule type absolute encoder accurate positioning movement distance
Wind speed standard automatic stop wind speed wind speed sensor
The PLC/ control console signal acquisition provides real-time feedback on the operation status
Brake condition special sensor fault fast positioning, to ensure the safety of operation
Anti-wind and anti-slip device, rail clamp/anchoring status sensor, wind prevention measure status visualization

7. Conclusion

The WTSM-A-06 system not only meets the requirements of national standards for the recording and display of crane operation data, but also passesDeep data analysisRealize active safety protection (such as hook slip warning, fault diagnosis, and life prediction), significantly enhancing the safety management level and accident prevention capability of gantry cranes in ship repair and construction scenarios.
