Postural constraint

G = 0

Steps are just wide enough to allow unrestricted passage.

Grip on load

A = 1 or
R = 2

Bulky tub with grips provided. Notice how the grips bend outwards when the tub is lifted up. Also, to climb the steps the operative must lift the tub high to clear his legs. This reduces the effectiveness of the grip from the handle.
