A hoist trolley assembly includes first and second hoist trolleys, electric motors to drive the trolleys and a control system. The control system receives a preliminary speed reference for the trolleys and forms a final speed reference for the first hoist trolley by using initial data including the preliminary speed reference. The control system is adapted to use a hoist trolley coefficient Krb that is calculated by k rb = T A_nom T B_nom · v B_nom v A_nom · m TB + m LB m TA + m LA , wherein TA—nom=the rated torque of the electric motor of the first hoist trolley, TB—nom=the rated torque of the electric motor of the second hoist trolley, vA—nom=nominal speed of the first hoist trolley, vB—nom=nominal speed of the second hoist trolley, mTA=dead weight of the first hoist trolley, mTB=dead weight of the second hoist trolley mLA=load of the first hoist trolley, and mLB=load of the second hoist trolley.
