AI Technical Summary
Technical Problem
The existing excavator's counterweight cannot be adjusted during use, causing instability in the entire vehicle, especially when the front load changes, making it prone to shaking or tipping over.
Method used
It adopts a hydraulic cylinder and linkage mechanism with hydraulic lock, and realizes the front and rear adjustment of the counterweight through the track and limit groove structure. The hydraulic locking position is used, which makes the structure stable and occupies little space.
Benefits of technology
This allows for flexible adjustment of the excavator's center of gravity, improving the overall stability and safety of the vehicle and avoiding the risks of swaying and tipping over.
