Imagine a construction site where only the excavator operator is required to work in the cab and no more workers are needed to perform tedious auxiliary calibrations, pile preparation, wire pulling, etc. in the harsh construction environment. FJD G31 Excavator Guidance System is making this scenario a reality.FJD G31 Excavator Guidance System is excavator guidance that integrates self-developed 3D modeling algorithms, inertial measurement sensing technology, and RTK (Realtime kinematic) centimeter-level positioning, aiming to transform excavation projects into more accurate and efficient processes with less labor cost. FJD G31 can be applied in varieties of complex construction scenarios like land leveling, wading operation, deep excavation, and slope cutting,making operators no longer check the depth and slope repetitively. FJD G31 can help you reduce fuel consumption by 45% and labor hours by 35% through innovative digital construction.

FJD G31 contributes to digital excavation construction

Advanced Sensor Modules Improve Accuracy

FJD G31 achieves operation accuracy of ±3cm by combining with self-developed multi-type sensor modules, which greatly provides construction accuracy and meets the accuracy requirements of most construction sites. These sensors are mounted on the boom, bucket and the vehicle body to obtain precise data on the position and movement of the bucket, thus enabling precise maneuvering of the bucket. Meanwhile, combined with the tilt sensor to detect the tilt and position change of the bucket, it can maximize the accuracy of the construction operation and reduce the number of reworks caused by the accuracy error, thus enhancing the operation efficiency of the excavator and reducing the construction cost.

Visual Operating System Contributes to Efficient Construction

Based on HMI platform, FJD G31 applies visual operating system to the working scene with 3D visual guidance, virtual datum line, etc. to achieve real time monitoring. It presents every step of the project from design to construction in front of operators to accurately complete each excavation action and ensure the construction quality and progress. Therefore, the visual system is quite conducive to operate excavator. There are three task generation modes to help manage tasks in the visual system. Operators can choose different modes according to different work scenarios, set the slope and height, or import CAD files, or even design on site. Flexible and easy-to-operate, the visualization system eliminates a lot of repeated checking and a large number of personnel to assist the design on the ground, so that the workflow is more efficient and saves more time and labor costs.


Based on RTK & GNSS, Achieving Efficient Construction

In the conventional construction process,surveyors are supposed to work repeatedly with RTK devices to adjust excavation data on survey points, which is not only time-consuming but labor-intensive. FJD G31 is the game-changer to this situation. FJD G31 can provide accurate positioning based on RTK and most advanced GNSS for operators, meanwhile showcase Real-time access to the coordinates of stick and bucket to help operators precisely navigate bucket teeth, which can improve project efficiency and eliminate tedious surveying works.
