In recent years, unattended weighbridges have become a "cost reduction artifact" in the logistics, building materials, and mining industries, but many companies still question their actual value. Today, we combine the case of a building materials factory we served, and use real data to disassemble the cost saving logic of unattended weighbridges.
1. Labor costs: directly cut off the full-time weighing post
The building materials factory was previously equipped with 2 weighers, with an average monthly salary of 6,000 yuan, plus social security and other benefits, and the annual labor cost exceeded 150,000 yuan. After the 150-ton unattended weighbridge is activated, there is no need for special personnel to be on duty, and only one part-time person is required to regularly inspect the equipment, which directly saves more than 120,000 yuan in labor costs every year, and avoids the risk of scheduling gaps and mistakes in manual operation.
2. Efficiency cost: Bicycle weighing speed is increased by 80%, reducing site congestion loss
When weighing manually, it takes more than 5 minutes for a bicycle to go down through the process of vehicle registration, data entry, and document printing, and there is often a long queue at the entrance of the factory during peak periods, which not only affects transportation efficiency, but also may lead to delays in the supply of raw materials. The unattended weighbridge compresses the weighing time of a single vehicle to 30 seconds, increases the average number of weighing trips per day from 200 to 350, increases the feeding efficiency of raw materials by 75%, and reduces production delays due to congestion to almost zero.
3. Cheating loss: from 50,000 yuan to almost no loss per month
Manual weighing is prone to cheating behaviors such as "favor weighing" and "edge weighing", and the building materials factory previously lost more than 50,000 yuan per month due to data deviation and cheating. The unattended weighbridge is equipped with infrared positioning, video capture and sensor encryption functions, without manual intervention throughout the process, the data is automatically uploaded and cannot be tampered with, and the monthly loss is reduced to less than 1,000 yuan after activation, and the annual loss is recovered by more than 500,000 yuan.
On the whole, the unattended weighbridge investment of the building materials factory has paid back in less than 10 months, and it can also stably create cost savings of more than 600,000 yuan every year, and its cost reduction value far exceeds the initial investment.
