The newly launched 6-tonne electric drive wheel loader 669G (423.9 kWh) is an important step for SEM in responding to energy changes and better supporting customers. The machine is equipped with an 8-tonne-class manual-automatic fixed-shaft transmission and heavy-duty axles, delivering strong traction and excellent durability to easily handle various demanding working conditions. The electronic control system precisely allocates power output, fully unleashing motor efficiency, effectively reducing energy consumption, and comprehensively improving operating performance to bring customers higher operational efficiency. In addition, the 5-tonne electric drive wheel loader 659G (350.2 kWh and 282 kWh) has already been launched in China to meet customers' diverse needs.

As an 8-tonne high-efficiency wheel loader combining power and energy-saving advantages, the 688G features hydrostatic transmission and a dual-variable hydraulic system, delivering high traction at low throttle, saving fuel and improving efficiency, and easily handling a variety of working conditions. A comfortable driving experience, excellent handling performance, and reliable, durable core components fully meet customers' expectations for high efficiency, low consumption, and comfort.

The SEM 656G is a 5-tonne diesel wheel loader built specifically for heavy-duty working conditions, with strong power and a robust structure to easily handle high-intensity loading tasks. The extra-long wheelbase design effectively improves machine stability; the fixed-shaft transmission supports shifting without stopping, making operation convenient and efficient; and an optional electronically controlled automatic transmission system enhances adaptability to various working conditions, making it widely suitable for heavy-duty applications such as ports, mines, earthworks, sand and gravel, and tunnels.

Adhering to SEM's consistent design philosophy of high efficiency, reliability, and user-friendliness, the 3110F wide-body dump truck is equipped with a mature, industry-mainstream engine, paired with a mining transmission and mining-specific axles to form a golden powertrain, giving the machine strong power and higher operating efficiency. The product has a flat-load body capacity of 43 m³ and a maximum payload of 80 tonnes. It adopts a mining-specific integrated flexible frame with strong bending and torsional resistance, and is highly adaptable to high-temperature, severe-cold, and high-dust working conditions, easily meeting the challenges of various extreme operating conditions.

A key customer handover ceremony was held simultaneously at the launch event. SEM Product Manager Xie Shuyin and SEM Global Marketing Manager Shi Yafei personally presented the new vehicle keys to the customer, symbolizing that the cooperation between the two parties has entered a new stage.
