PROBLEM TO BE SOLVED: To provide a movable crane including a slewing upper structure which may be used for a latticed boom and a telescopic boom.SOLUTION: A main hydraulic oil tank storage part 34 for storing a main hydraulic oil tank 33 is formed at a rearmost part of an engine storage house 20 provided at the left side of a slewing upper structure. A sub hydraulic oil tank storage part 36 for storing a sub hydraulic oil tank 52 is formed at a rearmost part of a device storage house 21 provided at the right side of the slewing upper structure. In a state where a latticed boom is attached to the slewing upper structure, only the main hydraulic oil tank is installed. When a telescopic boom is attached to the slewing upper structure, the sub hydraulic oil tank is stored in the sub hydraulic oil tank storage part and the main hydraulic oil tank communicates with the sub hydraulic oil tank through a hydraulic oil circulation pipe at a lower part and an air hose at an upper part.
【課題】ラチスブーム用とテレスコピックブーム用とに共通化できる上部旋回体を備えた移動式クレーンを提供する。【解決手段】上部旋回体の左側に設けられたエンジン収納ハウス20の最後部に、主作動油タンク33を収納する主作動油タンク収納部34を形成し、上部旋回体の右側に設けられた機器収納ハウス21の最後部に、サブ作動油タンク52を収納可能なサブ作動油タンク収納部36を形成する。上部旋回体にラチスブームを装着した状態では、主作動油タンクのみを設置し、上部旋回体にテレスコピックブームを装着したときには、サブ作動油タンク収納部にサブ作動油タンクを収納し、主作動油タンクとサブ作動油タンクとを下部の作動油流通管と上部のエアホースとで連通させる。【選択図】 図8
