METHOD FOR INDIRECTLY DETERMINING AN EXTENSION LENGTH OF AT LEAST ONE TELESCOPIC PUSH ARM OF A TELESCOPIC JIB

A method for indirectly determining an extension length of a telescopic push arm of a telescopic jib relative to a further telescopic push arm or to a main arm of the telescopic jib of a hoist includes a first sensor ascertaining a first parameter of the telescopic push arm and/or telescopic jib. On the basis of the first parameter, a first virtual extension length is determined and/or calculated. The first sensor and/or at least one further sensor ascertains a further parameter of the telescopic push arm and/or telescopic jib. On the basis of the further parameter, a further virtual extension length is determined and/or calculated. The extension length of the telescopic push arm or the telescopic jib is determined and/or calculated by the first virtual extension length and the further virtual extension length.
