Case 1: Paris Inland Water Ecological Renovation – Intelligent Crawler Robot Solves Urban River Sediment Blockage
1. Client Full Background
This client is a medium-sized municipal environmental engineering enterprise headquartered in central Paris, with 42 full-time construction personnel and fixed cooperative relations with 7 local municipal governments. Its core market covers small and medium inland rivers, landscape water bodies, and marina auxiliary water areas in the Paris metropolitan area. The main business includes river dredging, water ecological restoration, floating garbage cleaning, and post-dredging sediment harmless treatment. For a long time, the company rented traditional floating dredging vessels and adopted diver-assisted manual dredging to complete annual river governance bidding projects.
2. Core Pain Points Faced by the French Team
- Small urban rivers have narrow water surfaces and many underwater hidden obstacles such as abandoned steel bars and stones; large floating dredge equipment cannot navigate normally, resulting in low actual dredging coverage.
- French environmental supervision standards are extremely strict; traditional dredging vessels will stir up bottom sediment in the construction process, causing water turbidity exceeding the standard and triggering administrative rectification orders many times.
- Manual diving operation faces great safety hazards, and the company has to pay high occupational injury insurance premiums every year.
- The original construction mode requires 7 working days to complete a 1,200-meter river dredging task, often failing to meet the rigid delivery time of municipal bidding projects.
3. Targeted Matching Solution
Combined with the client’s construction water depth of 0.3–3 meters and sludge containing a small amount of hard sundries, we recommended the standard version of the underwater crawler cleaning robot. The equipment is equipped with a wear-resistant alloy cutting head to break solid impurities in sludge, a closed suction pipeline to prevent water body disturbance, and a 200-meter remote control cable to realize shore-based unmanned operation. Meanwhile, we provided a complete set of French operation manuals and 3 days of one-on-one online technical training, with a transparent quotation of dredging machine for sale without any additional charges for standard supporting hoses and monitoring screens.
4. Emergent Problems During On-Site Commissioning & Resolutions
On-site problem 1: The river contains a large amount of fallen branches and plant rhizomes, which are easy to block the suction inlet of the crawler robot during continuous operation
Solution: We delivered detachable anti-winding cutting blades as free accessories, and sorted out a set of regular inlet cleaning operation specifications for operators to conduct simple cleaning every 2 hours of continuous work, thoroughly solving the pipeline blockage failure.
On-site problem 2: Local municipal power supply voltage fluctuates in suburban river sections, leading to unstable power supply of the robot’s monitoring system
Solution: We sent matched voltage-stabilizing power supply modules free of charge, ensuring stable operation of the camera and walking system under unstable grid conditions.
5. Project Optimization Effects
- The overall dredging work efficiency is increased by 72%; the original 7-day river governance project is completed in only 2 days, shortening the overall project delivery period by 5 working days for each single river bidding project.
- Unmanned operation replaces 3 divers and 2 ground auxiliary workers, cutting monthly comprehensive labor expenditure by 3,100 Euros for the enterprise.
- Closed suction construction avoids water turbidity exceeding the standard, eliminating the risk of administrative fines, with annual fine loss reduced to zero.
- The service life of the crawler cleaning robot is more than 8 years, and the monthly maintenance cost is only 18% of the previous floating dredge rental cost.
6. Authentic Customer Feedback
“We spent nearly two months comparing multiple suppliers’ dredging machine for sale products and finally chose YG’s crawler dredging robot after field understanding of parameter performance. It perfectly adapts to the narrow urban rivers in the Paris area, the closed suction design helps us smoothly pass all municipal environmental inspections, and the remote operation eliminates the safety risks of divers. The shortened construction cycle enables us to successfully win 3 additional municipal river bidding projects this year. The technical team responds quickly to after-sales problems, and we plan to purchase one more device for our Lyon branch before the flood season arrives.”

Case 2: Bangkok Agricultural Irrigation Canal & River Sand Recovery – Crawler Dredging Robot Improves Farmland Water Supply Capacity
1. Client Full Background
This buyer is a large local water conservancy service contractor in Bangkok, Thailand, with 56 construction employees, covering most irrigation canal maintenance and shallow river sand collection businesses in central Thailand’s agricultural areas. Its main market is farmland water conservancy facilities, rural seasonal flood drainage channels, and shallow river sand raw material recovery for local building material factories. The enterprise used small manual sludge pumps and simple river sand grab buckets for a long time to complete dual tasks of canal desilting and river sand collection.
2. Practical Difficulties Encountered in Daily Construction
- Thailand has a long rainy season with high sludge viscosity in irrigation canals; manual pumps cannot completely clean hardened silt at the canal bottom, leading to insufficient water flow in farmland irrigation and frequent complaints from local farmers.
- Traditional grab bucket equipment has low precision for river sand collection, mixing a large amount of silt into finished river sand, resulting in low sales prices of sand materials for building materials factories.
- Scattered farmland canals are widely distributed with scattered construction points; the transportation and deployment efficiency of original equipment is low, consuming a great deal of vehicle transportation costs every month.
- The original manual centralized operation mode has slow progress, and the annual concentrated canal dredging work needs to invest a large amount of temporary seasonal labor resources.
3. Customized Matching Solution
Considering the client’s dual demands of canal dredging and river sand recovery, we configured a multi-functional crawler dredging robot integrated with dredging and sand extraction, belonging to our mature river sand dredging machine product line. The equipment is equipped with a graded screening structure inside the conveying pipeline to separate river sand and silt automatically during extraction. The lightweight crawler chassis is convenient for truck transfer between scattered farmland canals. We equipped English-Thai bilingual operation videos and provided a 12-month global spare parts supply guarantee for all dredging equipment for sale products.
4. Actual Difficulties During Equipment Deployment & Corresponding Solutions
Difficulty 1: The farmland canal bottom is covered with thick aquatic weeds, which are easy to wrap around the crawler walking wheels and cause walking jamming
Solution: We provided wear-resistant anti-winding wheel protective baffles as free supporting parts, and compiled operation steps for regular weed cleaning during equipment movement to guarantee smooth walking on complex canal bottoms.
Difficulty 2: The local ambient temperature is as high as 40℃ in the dry season, and the hydraulic pipeline of the robot is prone to high-temperature heating during long-time continuous operation
Solution: We upgraded the hydraulic heat dissipation structure for free and matched external auxiliary heat dissipation fans to ensure the robot can work continuously for 10 hours under a high-temperature outdoor environment.
5. Visible Improvement Benefits
- The canal dredging efficiency is increased by 65%, and the original 10-day centralized dredging task of regional irrigation canals is completed within 3.5 days, shortening the overall project period by 6.5 days each year.
- The built-in sand-silt separation structure improves the purity of recovered river sand by 43%, and the unit sales income of river sand products increases by 28% correspondingly.
- One set of crawler equipment replaces 5 seasonal temporary workers, reducing annual labor expenditure by 5,600 Thai Baht.
- The integrated equipment is easy to transport and deploy, cutting the monthly vehicle fuel and transportation cost by 42%.
6. Real Customer Feedback
“Our business includes both farmland canal cleaning and river sand collection for building materials. After comparing multiple floating gold dredges for sale and crawler dredging devices on the market, YG’s multifunctional crawler robot perfectly meets our two construction needs at the same time. The equipment runs stably under Thailand’s high temperature and muddy canal environment; the sand screening effect is very ideal, and our cooperation with local building material factories is more stable.
