The invention discloses a crawler crane boom structure and a crawler crane, and belongs to the crawler crane boom structure technology field. The crawler crane boom structure comprises a fixed auxiliary boom front pulling plate (3) connecting a main boom (1) with a fixed auxiliary boom (2), a single support (4) and a fixed auxiliary boom rear pulling plate (5). The fixed auxiliary boom front pulling plate (3) and/or the fixed auxiliary boom rear pulling plate (5) are connected with the single support (4) through an amplitude variation pulley block (11). A guiding pulley (12) is installed on the main boom (1) and an amplitude variation hoisting mechanism (13). The amplitude variation hoisting mechanism (13) is connected with the guiding pulley (12) and the amplitude variation pulley block (11) through a wire rope. The crawler crane boom structure can widen a working scope of an original single support fixed auxiliary boom and can achieve functions of a double-support tower-type auxiliary arm, the requirement of small-tonnage products for boom addition is met, the usage cost is lowered, a movable-type tower crane working mode can be evolved, and multiple functions of one machine are achieved.
