  We present a model system for objects, climbers, which have the ability to
move as ASEP particles with non-uniform forward and backward jumping rate
dynamics. These climbers are implemented as Mandal-Quan-Jarzynski [1] machines.
Climbers on a number of neighboring columns are considered. The low entropy
resource is provided abundantly to the first column, the unused part of this
resource is consecutively passed over to objects in neighboring columns. This
results in a hierarchy among the lanes. The system displays interesting
steady-states. Both open and periodic boundary conditions are considered and
results from Monte Carlo simulations of the system will be reported.
