The main function of the locking pin on an excavator is to prevent unnecessary rotation or swinging of the excavator during operation, thereby maintaining stability and safety in work.

The locking pin on an excavator is a mechanical component designed to quickly position and secure workpieces by locking and unlocking support rods or balls. This type of locking pin is typically controlled through a head button, allowing the excavator to remain stable in specific working conditions such as digging, loading, etc., without moving or rotating due to vibrations or external forces during operation. Particularly in situations requiring precision operations or working in high-risk environments, the role of the locking pin is crucial in ensuring the stable operation of the excavator, avoiding operational errors or equipment damage caused by unnecessary movement or rotation.

Additionally, the use of locking pins on excavators also involves the positioning and securing of workpieces, which can be quickly achieved through insertion and removal operations. This design not only improves work efficiency but also enhances safety. In specific working modes such as digging, loading, etc., the locking pin ensures that the excavator remains in a fixed position, preventing movement due to external forces or operational errors, thus ensuring precision and safety in work.

In conclusion, the locking pin on excavators, with its simple and effective design and operation, provides stability and safety in excavator operations, making it an indispensable part of modern excavator design.
