Abstract: A manipulator designed to handle loads on construction or public works si is shown and described. A motorized carrier (1) has an orientable pole (9) and an arm that can be folded and unfolded (16) hinged to the top of the pole and made of several elements (17, 18, 19) hinged together. The end of arm (16) is connected by a motorized link (29) to a telescopic and orientable motorized compensator arm (2) having at least one degree of redundant clearance and endowed with a stress-detecting active-compliance gripper carrier (36) supporting a gripper (3). Adjustment and control mechanisms are provided for the motorization of carrier (1), compensator arm (2) and link (29), while other means supply energy to and adjust and control gripper (3).
