Welcome to ZHONGMEI ! ☺

We specialize in manufacturing superior crawler excavators to bring you peace of mind in construction equipment.We understand the importance of having reliable and efficient machinery that can tackle any task with ease.

Super large excavators are commonly used in mining operations, large-scale construction projects, and other heavy-duty applications where massive amounts of earthmoving are required. They can efficiently excavate and load materials such as soil, rocks, and ores, making them essential machines in industries that require extensive earthwork.

Ultra large excavators typically consist of chassis, upper structure, excavation device, and control system components. The chassis is the foundation of an excavator, carrying the weight and excavation force of the entire machine. It is usually composed of tracks and track chains to ensure stable operation of the machine on uneven ground. The upper structure includes parts such as the engine, cab, hydraulic system, etc.

The engine is the power source of the excavator, usually using a diesel engine, with a power of several hundred to thousands of horsepower. The cab is the operator's work area, equipped with various control devices and displays, making it convenient for the operator to control and monitor the machine. The hydraulic system is the power transmission system of an excavator, which sends hydraulic oil to each hydraulic cylinder through a hydraulic pump to achieve various actions of the machine.

The excavation device is the core part of an excavator, mainly composed of a boom, a bucket, and a bucket. The boom is a component that connects the upper structure and the bucket, usually consisting of multiple telescopic arms that can be adjusted according to the depth of excavation and the scope of operation. The bucket rod is a component that connects the boom and bucket, usually composed of multiple telescopic rods, which can be adjusted according to different excavation heights and operating ranges. Bucket is the working device of an excavator, usually composed of shovel teeth and bucket body, which can be used for excavating, loading, and unloading various materials.
