Everything that touches the steps with the Escalera is soft
rubber. We have rubber wheels, rubber V-belt glide belts, and soft polyurethane lifting
feet. The V-belts maintain contact with the step, although they do no lifting they prevent
the Escalera from scratching the steps. The dual lifting feet on the Escalera stairclimber
put the same amount of pressure on the steps as the large six inch wheels do. This is
because they are the same width as the wheels and have the same amount of surface area. It
is interesting to note that some of the older Escalera's only had a single lifting foot in
the middle rather than the two that we have now. The reason that we changed is so that the
operator wouldn't have to balance the load in a sideways direction. However, there are
still a lot of these older units still in use and they still work fine with no damage to
the steps.
