The first stringer can be laid on the floor using blocks and one end of each riser is attached to each bracket so that the risers are in a vertical position in relation to the stringer. The risers are attached to each bracket using blind screws through the holes in the brackets. The second stringer is then positioned over the opposite ends of the risers and attached. A clamp may be used to pull the stringers tight against the riser ends. This one step will eliminate up to 80% of the custom fitting normally required for conventional stairs.
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.
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.
