3.5 Safety measures and instructions<br />
3.5.1 Control devices<br />
§ The manually rotated jib cranes with articulated arm, in the CBB column-mounted version and the<br />
MBB wall-mounted version can be controlled in the following ways:<br />
1 If fitted with an electric hoist the movements are activated:<br />
*by a push-button panel with ascent and descent buttons to control the lifting movement.<br />
2 If fitted with a manual hoist the movements are activated:<br />
*by mechanical working of the chain of the hoist for the lifting movement.<br />
3 In all cases the rotation movement of the jib crane arm, both in a clockwise and anti-clockwise<br />
direction, is activated manually, with a pushing flexing of the load.<br />
3.5.2 Safety and emergency devices<br />
§ The manually rotated jib cranes with articulated arm in the CBB column-mounted version and the<br />
MBB wall-mounted version, are fitted with the following safety and emergency devices:<br />
1. Rotating brake, by friction, which allows the regulation of the arm’s rotating force and ensures the<br />
stability of positioning.<br />
2. Anti-collision device, available on request, to avoid the telescoping of two or more arms which,<br />
operating in the same area, can interfere with each other; or to avoid the collision of the arm with<br />
surrounding structures.<br />
