[0087] Additional notes:

[0088] Roller weldment 6: Flipping device frame, with rotating shaft 3 installed in the center, and the center of mass designed on the axis of the rotating shaft to reduce the torque during flipping.

[0089] Rotation limit block 2011: Set the rotation limit block. When the rotation is in place, if the soft limit fails, the hard limit will be forced to stop to improve safety.

[0090] Fork arm 4: used for docking and picking up materials.

[0091] Fork roller 401: After docking the material, the operator needs to push the material to the limit position of the turning roller. The roller setting makes the operator's work more convenient.

[0092] Material holder lifting and locking plate 5: It moves up and down under the locking motor to lift and press the material.

[0093] Material Holder Buffer Anti-Slider 2041: This provides a buffering effect when the material holder's lifting plate is raised and locked, protecting the material from damage. Furthermore, it increases friction during the rollover process, preventing the material from sliding and improving safety.

[0094] Rotating shaft 3: When loaded with materials, the center of gravity is set at the axis of the rotating shaft. This effectively reduces the torque required for the turning mechanism.

[0095] Rotating pull pin 2042: When the material is loaded into place, the rotating pull pin is reset (manually) to prevent the material from sliding back. Safety precautions.

[0096] Rotation limit sensor 601: Soft limit. When the roller is turned into position, the sensor is triggered and the turning action stops. This ensures that the mechanism moves accurately when the button is manually operated.

[0097] Lifting welding frame 6: supports the frame, the flip module is installed in the lifting frame, and the drum flipping action is separated from the lifting frame. At the same time, it collects sand and gravel brought by wet materials.

[0098] Driving unit 8: It is composed of a worm gear, which increases the torque of the motor on the one hand and maintains the self-locking force on the other hand. When there is a power outage or other faults, the flip drum can maintain the current position, improving safety and preventing accidents.

[0099] Auxiliary wheel 7: balances the torque in all directions of the lifting system to make the movement of the mechanism more stable and safe.

[0100] The trolley handle 102 is ergonomically positioned for easy handling by the operator. The handles are located at both the front and rear for easy flipping and reversing of the trolley.

[0101] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
