乗手

乗, ride:        I think of this as a cable car (see the line overhead; the compartment in the middle; and the single guiding rail with flanges to keep your feet away underneath).
剰, surplus:   Cut that ride off -- you've gone too far!
棄, abandon:  I personally 厶 am blowing the lid 亠 off that cable car, abandoning it in mid-ride.
