Case

Case of Claim for Non – Standard Vehicle Tires

On April 29, 2017, Ms. Xu spent 247,000 yuan to buy a car at a 4S store in Shanghai. On March 7, 2018, her daughter had a tire blowout while driving. During maintenance, she learned that the tire was not the official standard run – flat tire for that model. Ms. Xu believed that the 4S store was fraudulent and demanded a refund plus triple compensation. The 4S store said it was a defect in the original factory assembly, not fraud. The court held that the 4S store had no fraudulent intent but had a performance defect, and awarded 50,000 yuan in compensation, rejecting other claims.

Shanghai Tire Detachment Fatal Case

On May 14, 2001, a Golden Dragon van owned by Shanghai Xiangsheng Medical Device Factory was driving on the Inner Ring Elevated Road in Shanghai. During the journey, the left rear wheel, along with the half – shaft, suddenly flew off. The wheel rolled over the road guardrail and fell from a height of 5 meters, hitting the head of Zhou Lei, a young man walking normally on the sidewalk under the viaduct. Zhou Lei died of craniocerebral hemorrhage despite full rescue efforts by the hospital. After the accident, the Shanghai Traffic Police Corps launched an investigation and commissioned relevant departments to conduct a technical appraisal of the involved vehicle. The appraisal conclusion showed that the deterioration of the lubrication condition of the left rear wheel half – shaft bearing was the cause of the accident. Zhou Lei’s relatives claimed 5 million yuan in compensation from the vehicle owner, the maintenance unit and the manufacturer, believing they all had unshirkable responsibilities. The three parties shifted blame to each other, and the case was difficult to handle due to the lack of authoritative appraisal institutions and industry standards.

Mercedes – Benz Tire Reversal Claim Case

In 2012, Ms. Yu spent 444,000 yuan to buy a Mercedes Benz at a 4S store. During maintenance in 2015, she found that the left front tire was reversed. During the annual inspection in 2018, it was found that the models and sizes of the two front wheel hubs were inconsistent, making the vehicle fail to pass the inspection.Ms. Yu believed that the 4S store was guilty of sales fraud and demanded a refund plus triple compensation, totaling 1.81 million yuan. The 4S store stated that the vehicle passed the inspection when delivered, there was no evidence of problems at that time, and Ms. Yu continued to use the vehicle afterwards, so it should not be held responsible.

A 66-ton electric mining truck has begun a six-month trial at the Granny Smith mine, aiming to improve energy efficiency and safety by combining the advantages of both

Goldfields’ Granny Smith gold mine recently introduced an Epiroc 66-ton electric mining truck for a six-month performance trial. This truck combines the performance of electric vehicles with the practicality of diesel engines, increasing climbing speed by up to 11%, reducing fuel consumption by approximately 7%, and incorporating multiple safety features. The trial will comprehensively collect operational data to support the mine’s transition to safer, cleaner, and more efficient underground transportation. The mine currently has 19 megawatts of solar power installed capacity, and by September 2025, approximately 20% of its electricity will come from solar energy.

Born for extreme cold and complex terrain: How BEEZONE customized construction machinery for harsh working conditions in Russia

The bulldozer production project, led by the Sino-Russian joint venture BEEZONE, has moved beyond simple assembly. Currently, two Russian factories are deeply customizing and modifying the Chinese-made construction machinery to adapt it to the complex operating environments of different regions in Russia. This has enabled BEEZONE bulldozers to be successfully applied in Russia’s mining, oil and gas extraction, and various large-scale infrastructure construction sectors. Qiu Rong, Technical Director of Bizhuo Construction Machinery Co., Ltd., said: “Multiple advantages have enabled us to gain a foothold in the Russian market. First, we have continuously optimized the structure and adaptability of our equipment and improved operational efficiency by deepening cooperation with local factories. Second, we have been constantly updating our product line and launching new products such as high-power and fully hydraulic bulldozers. In addition, we have been steadily improving our after-sales service system to drive secondary sales with high-quality service. These factors together constitute our market competitiveness.”
