起重机及其旋转伸缩踏梯
摘要：
一种起重机及其旋转伸缩踏梯,其中旋转伸缩踏梯，包括中空的固定座及楼梯主体，该楼梯主体可在该固定座内滑动，该楼梯主体的底部设有踏板，该旋转伸缩踏梯对应有全伸与全缩两种状态，且在全伸与全缩两种状态该踏板具有不同的朝向，该旋转伸缩踏梯处于全缩状态时，该楼梯主体收起在该固定座内且该固定座与该楼梯主体固定，该旋转伸缩踏梯处于全伸状态时，该楼梯主体伸出该固定座外且该楼梯主体相对于该固定座不可转动，该旋转伸缩踏梯在全伸与全缩两种状态之间进行变换时，该楼梯主体上提至使该楼梯主体的顶端超出该固定座的顶端，该楼梯主体此时可相对于该固定座旋转以改变该踏板的朝向。
摘要（英）：

The utility model discloses a crane and a rotary flexible step ladder thereof. The rotary flexible step ladder comprises a hollow fixed seat and a stair main body, wherein the stair main body can slide in the fixed seat; the bottom of the stair main body is provided with a pedal; the rotary flexible step ladder has a full extension state and a full retraction state correspondingly, and the pedal has different directions in the full extension state and the full retraction state; when the rotary flexible step ladder is in the full retraction state, the stair main body is folded in the fixed seat and the fixed seat is fixed with the stair main body; when the rotary flexible step ladder is in the full extension state, the stair main body extends out of the fixed seat and the stair main body cannot rotate relative to the fixed seat; and when the rotary flexible step ladder is switched between the full extension state and the full retraction state, the stair main body is lifted until the top of the stair main body higher than the top of the fixed seat, and the stair main body can rotate relative to the fixed seat to change the direction of the pedal.
