To provide a crane, especially a mobile crane.SOLUTION: A crane includes a crane base (2), a crane boom (6) that can swivel around a swivel axis (12) perpendicular to the crane base (2), and a counterweight support unit (10) that can swivel together with the crane boom (6) and has a predetermined number of counterweight modules (18) arranged. The crane has an anti-collision sensor system that monitors whether an object is present or not in a swivel area (32) through which the counterweight support unit (10) and/or the counterweight module (18) passes when the crane boom swivels. The crane also has a control unit (20) that is coupled with the anti-collision sensor system on the basis of signal transmission technology and determines whether the object is present in the swivel area (32) based on the signal from the anti-collision sensor system, and determines whether the object may collide with the counterweight support unit (10) or one of the plurality of counterweight modules and takes measures if there is a possibility of collision.SELECTED DRAWING: Figure 1

    【課題】クレーン、特に移動式クレーンを提供する。【解決手段】クレーンベース(2)と、クレーンベース(2)に対して垂直な旋回軸(12)を中心に旋回可能なクレーンブーム(6)と、クレーンブーム(6)に共に旋回可能で、所定数のカウンタウエイトモジュール(18)が配置されたカウンタウエイト支持部(10)を備える。旋回時、カウンタウエイト支持部(10)及び/又はカウンタウエイトモジュール(18)が通る旋回領域(32)に、物体が存在するか否か監視する衝突防止センサシステムを備え、衝突防止センサシステムと信号伝送技術的に結合され、衝突防止センサシステムからの信号に基づき、旋回領域(32)に物体が存在するか否かを判定し、物体がカウンタウエイト支持部(10)と又は複数のカウンタウエイトモジュールの1つと衝突する可能性があるか否かを判定し、衝突の可能性がある場合には対策を講じる制御装置(20)を備える。【選択図】図1
