Project Name: 2025 Truck Scale Maintenance, Repair, Maintenance, and Calibration 3. Procurement Category: Maintenance and Overhaul Project 4. Project Content and Requirements: 4.1 Project Main Content: The client entrusts the contractor to undertake the daily maintenance work of seven truck scales located at the Lotus Pond and Baguan River sites, three belt scales on the production line, and one truck scale for Ruizheng Commercial Concrete, as well as several batching scales on the Ruizheng and Ruiding production lines. The specific content is as follows: (1) Maintenance Content: The contractor needs to maintain 24-hour communication. The client shall notify the contractor of any problems or equipment malfunctions that occur during the use of the truck scale within the scope of the agreement.

After the inspection is completed, a written inspection and maintenance report shall be submitted to Party A, which shall include routine inspection items, problems found, and equipment status analysis. (3) Verification content: Each truck scale shall be verified at least twice a year, and the designated verification unit shall be Panxi Vanadium and Titanium Inspection and Testing Institute. After each verification is completed, a testing report shall be provided in a timely manner. At the same time, due to the need for weights in the verification process, Panxi Vanadium Titanium Inspection and Testing Institute does not provide weight transportation services and needs to hire vehicles and personnel from third-party companies to transport weights. Therefore, the weight transportation business will be merged into the verification business, and the contractor will be responsible for it together. The weight transportation vehicles and personnel responsible for the contractor shall comply with the on-site safety management of the commissioning party. If any safety accidents occur during the weight transportation process, the contractor shall be fully responsible. (4) Maintenance plan for a total of 3 car scales: Due to the high usage of the company's car scales, the beam of the scale body has deformed to varying degrees, and there is a phenomenon of welding deformation at the connection joints. Using the scale body with defects is prone to breakage, and in severe cases, it can cause the vehicle to roll over, resulting in casualties. Urgent maintenance is needed; At the same time, the weighing sensor has severe attenuation and inaccurate measurement, requiring maintenance and replacement. The specific requirements are as follows: ① Repair a truck scale for Baguan River gravel, lift out the scale body, correct and reinforce the main beam through welding, and at the same time reinforce and weld the joints at the connection points and install them. ② Repair one lotus pond slag factory slag sand and one gravel truck scale, a total of two. After lifting out the scale body, correct and reinforce the beam by welding, and at the same time reinforce and weld the joints at the connection points and install them Replace 30 sets of weighing digital sensors. Sensor requirements: 50t, accuracy OIMLC3, IP protection level IP68, waterproof and dustproof, using column and plug-in cable series connection, no junction box form, with automatic diagnosis, automatic warning and lightning protection functions Replace 3 weighing digital instruments. Instrument requirements: Protection level IP
