Caterpillar has launched new tracked and wheeled excavators, as well as a wheeled loader at BICES exhibition in Beijing, specifically designed for the Chinese market. These included the 3.1 cu m class 950 GC wheeled loader, two new wheeled excavators  the 33 tonne class M315D2 and 38 tonne class M317D2  as well as the 36 tonne class tracked 336D2 excavator and 22 tonne class 320D tracked excavator. Key trends in the new launches include a robust and heavy-duty design and a focus on advanced hydraulics and fuel efficiency. The 320D, for instance, features a boom and stick regeneration system that is said to save energy during boom-down and stick-in operations, reducing cycle times and adding to overall fuel efficiency.

Meanwhile, the 336D2?s US Tier 2/EU Stage II-compliant Caterpillar C9 Acert engine boasts a new three-stage fuel filtration system designed to remove harmful contaminants from potentially low-quality fuel. The aim is to improve the machine?s uptime and the service life of fuel system components. The 950 GC wheeled loader features a 168 kW C7.1 engine that meets US Tier 3/EU Stage IIIA emissions standards.
