L-shaped frame carrying system and method

The invention discloses an L-shaped frame carrying system and method.The L-shaped frame carrying system comprises a temporary storage frame and an AVG transfer trolley, the AVG transfer trolley comprises a trolley body frame, trundles and a clamping assembly, and the trundles and the clamping assembly are located in the trolley body frame; the trundles are symmetrically arranged on the two sides of the bottom of the trolley body frame. The trundles on the two sides of the bottom are located on the two sides of the temporary storage frame correspondingly, and the clamping assembly is located above the temporary storage frame. The clamping assembly is connected with a lifting driving piece, and the lifting driving piece can drive the clamping assembly to ascend and descend in the direction close to or away from the temporary storage frame. According to the L-shaped frame carrying system and method, the vehicle body frame stretches across the temporary storage frames, so that the width of a channel between the t
