The main features of excavators include the following aspects:
High technical performance: Compared with mechanical excavators, hydraulic excavators can increase digging force by 30%, reduce the weight of the whole machine by 30%, and improve walking speed and climbing ability. In addition, the hydraulic transmission device can achieve stepless speed regulation, a large speed regulation range, smooth movement, and small impact.
Simplified structure: Hydraulic transmission eliminates complex intermediate transmission parts, is easy to maintain, and the movement inertia of hydraulic components is small, which is suitable for frequent reversing operations.
Strong adaptability: Various safety overflow valves are provided in the hydraulic system to reduce mechanical damage caused by overload or misoperation. In addition, the widening and lengthening of the crawler device makes the excavator adapt to complex terrains such as wetlands and swamps.
Simple operation: The use of hydraulic servo mechanism makes the operating force small and the movement flexible, which improves the working conditions of the driver.
Versatility: The excavator can realize a variety of operating functions by replacing different working devices, such as loading, lifting, bulldozing, etc.
High efficiency: The high efficiency transmission and control system of the hydraulic system enables the excavator to maintain high working efficiency under various working conditions.
These characteristics make the excavator one of the main construction machinery in engineering construction, and it is widely used in the excavation and loading of materials such as soil, coal, and mud.
