ThyssenKrupp’s Stair-Glide has advanced features, the most significant of which is the hand pendant control; fold up arms and the foot obstruction sensors. In addition to these features, the stair lift also has over speed brake and a joystick control on the arm, which makes the control easier even for people who are not able to use their hands properly. Stairs are composed of stringers, stair treads and stair risers. The stringers are the slanted members on the sides of the stairs which sit on the floor and are tightly attached at the top of the staircase. In most stair construction, there are two stringers installed on each set of steps. The stair treads are the sections in which you step on to travel up and down the stairs. Stair treads are usually made of wood.
Finished interior stairs are perhaps the toughest challenge that a wood worker will face and are often the exclusive domain of the "stair specialist". This is particularly true with the more complicated systems such as circular stairs. However, when it comes to straight runs, adjustable bracket systems greatly simplify the process. Using adjustable bracket systems allow a person with only basic skills to build a well finished interior stair with a high degree of accuracy and elegance.
Curved stairs are not as safe as a strait set of stairs. Curved stairs get very narrow on one side. A curved set of steps may be difficult to negotiate in an emergency or fire situation. Handrails should be installed on at least one side of the stairs that has two or more risers. Properly configured stair handrails should 34 inches high and they should be designed to comfortably accommodate a person wrapping their hand around the rail. Guardrails also should accompany a handrail system on a properly configured set of steps. The gaps should be only 4 inches wide so that the body of a child can not fit though the openings.
