Control monitoring device for tower cranes

Abstract

The invention relates to a control monitoring device for tower cranes, in particular for small cranes, with integration of functions, and adapted for radio control. The device comprises, in respect of all the movements of the crane, such as hoisting, rotation, distribution and translation, a monitoring/control electronic unit (2) receiving at its inputs and processing the control signal (4) originating from the radio control box (3), and also receiving signals (5, 8, 9, 13, 15, 17, 19, 21) originating from sensors (6, 8, 11, 18, 20, 22, 23, 24) and from switches (14, 16). The electronic unit (2) delivers start and stop commands (27, 30, 31, 33, 34) at its outputs, while monitoring the action of the speed regulators (28) or other control members (35, 36) assigned to the movements, as well as the action of the crane's safety devices (32).
