A residual capacity indicator and load measuring system for aerial lifts of the type having a pair of articulated arms mounted on a revolving turret and having a jib and a bucket provided at a free end of the upper one of the two articulated arms comprises first and second protractors for measuring the respective angles of the upper and lower arms, an angle measuring device for measuring, in any given position of the aerial lift, the angle of the jib, and a reach measuring device for measuring the extension of the jib, all of the data obtained thereby being fed to a micro-processor which determines the load capacity of the lift in a given position thereof. The system also uses strain-gauges to measure the load on the jib. The micro-processor determines by way of the capacity and jib loads a residual load of the lift. A display device displays the residual load to the lift operator and an alarm informs the operator of an overload of the lift. The measurements are transmitted to the micro-processor by fiber optic or radio wave technologies and the micro-processor records high residual loads and residual overloads. The present invention also proposes a method for determining the residual load of the aerial lift.
