Mobile concrete pump with distributing boom
摘要：
A mobile concrete pump comprising a structural frame (14) mounted on the undercarriage (10) of a truck chassis (12), a boom stand (22) that is provided on the structural frame (14) and that is rotatable about a vertical axis (20) and a concrete distribution boom (24) configured in the form of multi-arm articulated boom (24). The concrete distributing boom consisting, for example, of six arms, which arms can rotate with respect to one another. In order to make possible the use of a distributing boom with a longer reach, a trailer (32) having its own undercarriage (34) is provided, said trailer being connected to the truck undercarriage (10) by a coupling member (36) in the transport condition. The trailer (32) has a pivot member (40) rotatable about a vertical axis (38) for receiving an arm set (42) that projects beyond the rear end of the truck undercarriage (10) in the transport condition.
摘要（中）：

一种可移动混凝土泵，包括安装在卡车底盘（12）的底架（10）上的结构框架（14），设置在结构框架（14）上并且可绕垂直轴线 （20）和以多臂铰接吊杆（24）的形式构造的混凝土分配吊杆（24）。 混凝土分配臂由例如六个臂构成，臂可相对于彼此旋转。 为了使得可能使用具有较长距离的分配吊臂，提供具有其自己的底架（34）的拖车（32），所述拖车通过联接构件（36）连接到卡车底盘（10） 运输条件。 拖车（32）具有可围绕垂直轴线（38）旋转的枢转构件（40），用于接收在运输状态下突出超过卡车起落架（10）的后端的臂组件（42）。
