ABSTRACT:
An attachment jib for supporting various working devices, such as a pipe manipulator, includes a support base which can be rigidly coupled removably with existing elements on the nose block of a telescopic crane boom. The jib includes telescopic sections and its base section is pivotally mounted on the support base and is luffed by power cylinders on such base through a wide angle. The jib contains another power cylinder to control extension and retraction of its fly section carrying the working device. An optional work support platform pivotally connected to the support base may be used either with or without the jib.
