Equine Assisted Therapy for disabled individuals has been popular for over 40 years.
The challenge has always been finding a safe and effective way to allow people with mobility issues to mount a horse.
Weight - A ramp system large enough to support a wheelchair and helpers is going to be very heavy.
Portability - A wooden system is a permanent installation. You had better be very sure of where you want the ramp when you build it.
Walking surface - Wood ramps have a tendency to offer poor traction. Conventional enhancements such as grip tape or special paints lose their effectiveness almost immediately as they get covered with dirt and other foreign matter from the mounting area. Wood surfaces are also almost impossible to clean.
Weight - Weight isn't an issue with an aluminum ramp. They are modular in nature, so each part can be easily handled by 2 people working together.
Portability - An aluminum mounting ramp can be stored in pieces and transported in the back of a pickup truck. It can be assembled wherever it is needed in 3 minutes by 2 people without any tools or special skills.
Walking surface - An aluminum mounting ramp has the same non-slip walking surface used in ramp systems for homes and businesses. The surface requires no special treatment or maintenance and can be cleaned completely with a garden hose.
