An architectural environment in which people cannot move freely is an act of discrimination. We at TREZ have developed a set of products that will allow all people access to the building levels, whether in a wheelchair, do not see or hear well, or are mothers with babies in strollers. All TREZ passenger lifts comply with EN 81-70 European standards for an accessible environment in an elevator. However, a passenger elevator is more difficult to complete in a new building up to 3 floors. It is quite difficult to build an external passenger elevator to an existing building, so we created the PDS Lift and the PDS A Lift. Their main difference with passenger lifts is that they are designed under the machinery directive, while passenger lifts are designed under the elevator directive. This gives a certain freedom to TREZ engineers. As a result, PDS is lighter, quieter, more economical, does not load the walls and tiles of the building, can be installed directly on the finished floor, its shaft can be from bricks, no engine room, no pit, and no headroom of the lift shaft.
