Freight monitoring system for power construction and transportation cableway

In complex terrain, freight cableways are widely used in power construction, mining transportation and other fields as an efficient mode of transportation. However, there are safety risks such as blind spots in supervision, difficulties in positioning, and risks of overload on traditional freight cableways. In response to these problems, Weite Safety Technology has launched a freight cableway monitoring solution to ensure the safe and efficient operation of the freight cableway through high-precision positioning and real-time weighing technology.

Safety challenges facing freight cableways

The freight cableway is a special transportation system that erects wire ropes on the support structure as a running track for the construction and transportation of materials for overhead power transmission lines. However, there are many problems in practical applications.：

​Regulatory blind spot​: The cableway has a large span and long spacing between brackets, making it difficult for traditional methods to achieve effective supervision and real-time monitoring.

​Difficult to locate​: The lack of positioning equipment that can monitor the whole process of cableway operation makes it difficult for managers to understand the transportation location in real time.

​Overload risk​: Simple freight cableways generally lack weighing devices, and overload operations occur from time to time.

​Security risks​:Overloading operations exacerbate equipment wear and tear, increasing the possibility of safety accidents.

Overview of micro-special transport cableway monitoring system

The micro-special transportation cableway monitoring system integrates positioning and weighing functions, and provides a comprehensive guarantee for the safe operation of the freight cableway by tracking the position of the trolley in real time and monitoring the load.

System core functions

​High-precision positioning​: Beidou RTK technology is used to achieve precise indoor and outdoor positioning of the trolley, with a positioning accuracy of 30 cm.

​Real-time weighing​: Accurately measure the load of the trolley, prevent overloading operations, and ensure transportation safety.

​Video surveillance​: Equipped with a comprehensive video surveillance system to grasp the situation on the transportation site in real time.

​Safety and security​: Through real-time monitoring and early warning, the risk of safety accidents is significantly reduced.

Detailed system functions

All along, the safety management of cableway transportation between hills, mountains, and high mountains has been very strict. In response to this difficult problem, Weite has developed an intelligent monitoring and management system for cableway transportation, which effectively improves construction efficiency on the basis of ensuring safety, and has been successfully applied in a number of power construction projects.

High-precision positioning module

​Centimeter-level positioning​: Beidou RTK technology is used to achieve real-time tracking with an accuracy of 3 cm to ensure that the position of the trolley is accurate and controllable.

​Wide area coverage​: A single base station covers a range of 20 kilometers, and the IP67 protection level is suitable for harsh outdoor environments.

​Portable terminal​: Maintain stable positioning and data transmission in a dynamic environment to meet the needs of complex working conditions.

Intelligent weighing module

​Real-time weight measurement​: Accurately monitor the load and effectively prevent overloading operations.

​Scientific distribution​: Rationally allocate the distance between the trolleys and control the number of cableway trolleys between the door frames.

​Loading and unloading reminder​: Intelligent reminder of operators to load and unload materials, greatly improving the efficiency of cableway transportation.

Successful application cases

The transportation cableway monitoring system provided by Weite for a power construction project in Hainan has been well received by customers. The system has the following characteristics：

• Real-time monitoring and accurate display of cargo weight
• Significantly improve the efficiency of cargo transportation
