TENSION FORCE EQUALIZER IN A ROPE SYSTEM USING A PROXIMITY SENSOR [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2021 Different values of tension forces in the load-bearing ropes of elevators, which push the rope into the grooves of the traction discs with different pressure, are the cause of uneven wear of the grooves of the traction discs under operating conditions ...

Computational fluid dynamics modeling of rope-guided conveyances in two typical kinds of shaft layouts. [PDF]
PLoS ONE, 2015 The behavior of rope-guided conveyances is so complicated that the rope-guided hoisting system hasn't been understood thoroughly so far. In this paper, with user-defined functions loaded, ANSYS FLUENT 14.5 was employed to simulate lateral motion of rope ...
