AI Technical Summary
The existing crane grab bucket lacks a mechanical locking mechanism, which may cause the mechanical claw to open unexpectedly during the lifting process, resulting in material falling and reducing the practicality of the device.
A crane garbage grab assembly was designed, which uses a drive cylinder to drive the lifting hinge seat and hinge rod to rotate the grab rod. Combined with the drive motor to drive the turntable and locking slide, the grab is locked to prevent accidental opening. A shearing blade is set on the grab to facilitate cutting garbage. A high-performance drive cylinder is equipped to ensure that the grab opens and closes synchronously.
This effectively prevents the grab bucket from opening accidentally during the lifting process, improving the practicality and applicability of the device, while also increasing work efficiency and operational stability.
