Abstract
An load moment indicator, in a crane provided with hoist means of a main side and an auxiliary side, including a calculator in which a reference value if a rated load determined by the stability of a crane or the like is preset, a hoist load of the other side is converted into a load component of its own side, and the converted value is subtracted from a reference value of its own side to thereby obtain a rated load of own side, or in which a tolerant load that can be suspended by the other side is converted into a load component of its own side on the basis of a base of a reference value of the other side, and the converted value is compared with the reference value of its own side to select a lower value. Thereby, it is possible to make the most of the suspending ability of the main side and the auxiliary side and for an operator to grasp clearly a tolerance of the hoist load.
