A ramp is a sloped pathway that provides access between two vertical levels. It enables the movement of wheelchairs, bicycles, and other wheeled vehicles. They are widely used in public buildings, railroad stations, stadiums, hospitals, and exhibition halls. Ramps are highly desirable for all buildings, especially to accommodate persons in wheelchairs. The slope of the ramp is called a gradient or steepness and, it can be expressed in ratio or percentage.
Generally, a clearance space of 120 to 180 cm between the handrails is recommended to allow comfortable and easy passage of the wheelchair through the ramp. An intermediate handrail can be provided for ramps designed for a width greater than 180 cm. The finishing material of the ramp must give a hard non-slip surface. This surface must work safely both in dry and wet conditions.
The design considerations for handrails for ramps are as follows:
- Handrails for ramps are continuously provided without any interruption along the length on either side.
- Handrails are built in a fixed position.
- The handrails are made using smooth materials that do not change with temperature variations.
