PRODUCT INTRODUCTION
The LG220E tracked excavator was launched three years ago and is known for its reliable operation under harsh conditions. In addition, market feedback indicates that users are impressed by the engine power of 223 kilowatts and bucket capacity of 1.8-3.28 cubic meters at 2000 revolutions per minute of this machine.
The LG220E crawler excavator series has a working weight of 52200 kilograms and advanced features such as higher productivity, greater on-site stability, and lower operating costs compared to previous machines.
The LG220E excavator adopts an environmentally friendly diesel mechanical engine, which integrates the constantly developing engine technology of Laigong. Various system improvements ensure greater maximum engine output, thereby reducing the workload of the engine during machine operation. Lai Gong also improved the components of the engine to eliminate the possibility of on-site malfunctions. The improved design and materials of key components including the engine cylinder block, cylinder head, and piston have significantly extended the service life of the engine.
The large fan size improves the efficiency of air, hydraulic oil, and fuel filters, enhances cooling performance, and thus reduces fuel consumption.
The new design features adopt the latest ergonomics, improving safety and comfort, ensuring that operators work under conditions conducive to high productivity. The spacious all-weather soundproof cab provides a clear on-site view, effective air conditioning and adjustable seats, as well as an optional air suspension system to reduce vibration and improve comfort.
The control panel is conveniently located, easy to use, and easy to read. To improve safety, there are large handrails and wide steps with anti slip plates, left and right rearview mirrors, travel alarms, and safety glass.
