The invention relates to a crane landing leg supporting device and a crane, the crane landing leg supporting device comprises a fixed supporting component (2) and a movable supporting component (3), the fixed supporting component (2) comprises a first plate-shaped component (21) and a slideway (25) which is arranged on the plate-shaped component (21) and extends along a first direction perpendicular to the thickness direction of the plate-shaped component (21); the movable supporting component (3) is arranged in the sliding way (25) in a sliding mode in the first direction so as to extend out of the fixed supporting component (2) or retract into the fixed supporting component (2), and the movable supporting component (3) is arranged in the sliding way (25) of the fixed supporting component (2) in a telescopic mode. Therefore, the supporting leg supporting device can change the length of the movable supporting part (3) extending out of the fixed supporting part (2) according to different working sites, and the problem that an existing supporting leg supporting device of the crane cannot be suitable for various complex working environments is solved.
本发明涉及一种起重机支腿支撑装置和起重机,起重机支腿支撑装置包括固定支撑部件(2)和活动支撑部件(3),固定支撑部件(2)包括第一板状部件(21)和设在板状部件(21)上且沿垂直于板状部件(21)的厚度方向的第一方向延伸的滑道(25);活动支撑部件(3)可沿第一方向滑动地设置在滑道(25)中,以向固定支撑部件(2)的外部伸出或向固定支撑部件(2)的内部缩回,活动支撑部件(3)可伸缩地设置在固定支撑部件(2)的滑道(25)中,因此支腿支撑装置可根据工作场地的不同改变活动支撑部件(3)伸出固定支撑部件(2)的长度,解决了现有起重机的支腿支撑装置无法适用于多种复杂作业环境的问题。
