A passenger winch is a lifting system often used on construction sites to lift personnel and materials to the upper levels of unfinished buildings. The passenger elevator itself consists of a cage or cabin in which people will stand during transportation and a rail that is mounted to the building. The car or cage will travel along this track via a rack and pinion drive system, and the car can be stopped at various places along the track. This allows people to load or unload at any floor along the track.
The track itself is usually made of steel and constructed of various lengths fastened together. This provides stability and makes the passenger elevator construction process much faster and easier. These structures are usually temporary, so the smaller sections of track will also make deconstructing and transporting the pieces much easier to manage. The height of the passenger elevator varies depending on the number of road sections that join the building. In most cases, track pieces come in 25-foot (7.62-meter) sections, so the height of the finished track is usually a multiple of 25.
Once the track is in place, a cart or cage can be attached to it. This will be the main support structure for the goods or people being transported and is usually an open-air structure surrounded on all sides by a wall or gate. In some cases, the cage can be closed to prevent injury from falling debris or other items. The cage is driven along the passenger lift system by a motor that drives a rack and pinion system; this means that two or more gears will work together to raise or lower the cage. The specific system design will vary depending on the size and application of the passenger elevator.
Often the entire system is mounted on the outside of a building, although in some cases it is possible to mount the system within the building structure. However, this is a much more difficult process, as the rails often have to be placed using a large crane. Sometimes the passenger winch is a stand-alone unit that does not need to be attached to a building; This type of elevator typically features a platform at the top that allows passengers to walk from the hoist system to the structure being built.
