Types of curved rail lift
There are three types of curved rail stair lift- hollow tube rail, modular flat rail and custom flat rail.
Hollow tube rail: One or two tube rails are present in hollow tube rail that are curved using a pipe bender. This type of rails has less flexibility and smaller weight capacity than custom flat rail track. The gear rack of these rails are exposed which can get a limb or piece of clothing and hence are capable of causing accidents. Hollow tube rail gives smoother and faster ride than modular flat rail and it is cheaper than custom flat rail.
Modular flat rail: This rail uses many smaller modular pieces of track which are assembled on site. The chair travels over many modular joints resulting in slow rides.
