STABILITY CONTROL DEVICE OF A LADDER OR MOBILE SCAFFOLD

摘要

The present invention relates to an electronic stability- control device of a lift apparatus able to allow a person to raise him/herself in relation to a support surface, such as a ladder or mobile scaffold, he device comprises at least one inclination sensor able to detect the inclination of the apparatus at least in relation to two orthogonal axes (X, Y) defining a horizontal reference plane and to provide in output at least one digital control signal showing the value of such inclination detected, a microprocessor control unit able to receive said control signal from the inclination sensor, compare said control signal with at least one predefined reference value and provide in output a stability indicator signal showing said comparison, and at least one visual and/or audio indicator which can be activated by said stability indicator signal.
