Since lateral stiffness of existing wire ropes used as guide cables is difficult to achieve reliable guidance for conveyances in deep shaft wall, deflection-suppressed system is designed to reduce lateral displacement and enhance stiffness of guide cables. Theoretical method about cable stiffness is offered with multi-boundary constraints and validated by finite element method. With application analysis, the results show the lateral displacement and stiffness regulation under different boundary conditions. When guide cable tensions increase, the minimum lateral stiffness increases rapidly and later tends to vary linearly with two boundaries constrained, and its situation gradually moves to the middle. Besides, the increased boundaries lead to an increase in the minimum lateral stiffness by a certain linear ratio and the move of its position to the middle on the cable. The required minimum tensions at different boundaries are accordingly obtained. When the guide cables are arranged in different directions of the conveyance, their stiffness characteristics are revealed. Therefore, the arrangement of the two guide cables is proposed under multi-boundary constraints. The above study can be useful for reducing the conveyance deflection in cable-guided system and provide reference when selecting guide cable with multi-boundary constraints.
