The invention relates to a support device for a mobile crane, comprising a first support part, a second support part and a fixing device for preventing the second support part from moving in a moving direction and in any relative position between the first support part and the second support part, the fixing device comprising a fixing body, and a fixed body held in abutment with a slope formed between the first support portion and the second support portion by a holding device, and mounted relative to the first support portion and the second support portion such that a travel movement of the second support portion in a direction away from the support foot causes an increase in a force exerted by the fixed body on the slope, and thus the second support portion is fixed relative to the first support portion. The invention also relates to a mobile crane comprising such a support device.
本发明涉及一种移动式起重机的支撑装置,包括第一支撑部分、第二支撑部分和固定装置,该固定装置用于防止第二支撑部分在移动方向上以及在第一支撑部分和第二支撑部分之间的任何相对位置中移动,其中,固定装置包括固定体,该固定体通过保持装置与形成在第一支撑部分和第二支撑部分之间的斜坡保持抵接,并且相对于第一支撑部分和第二支撑部分安装成使得第二支撑部分在背离支撑脚的方向上的行进移动引起由固定体施加到斜坡上的力的增加,并且因此相对于第一支撑部分固定第二支撑部分。本发明还涉及一种包括这种支撑装置的移动式起重机。
