Manufacturing the donkey cart and ambulance
Practical Action
manufacturers in both North Darfur and Damazin. Many people living in rural
areas find it very difficult to access health centers or hospitals when they are ill.
It is hoped that the donkey cart ambulance can act as a means of safe transport
to these facilities when no motorized vehicles are available.
This manual aims to give useful information to local fabricators and
organizations that support them to help them make these intermediate means of
transport. Although we have tried to give accurate information there is more
than one way of making some of these components and their dimensions may
need to change depending on what is available in the local markets.
2. The Wheel Jig
2.1 Background
Access to wheel manufacturing technology enables
workshops to set up their own facilities to produce a
range of good quality wheels from standard steel
sections. Wheels can be made to take bicycle,
motorcycle, car and solid rubber tires and to suit a
range of low-speed vehicles such as handcarts, bicycle
trailers, wheelbarrows and animal drawn carts.
An assembly jig technology has been introduced by
Practical Action Technology to ensure that the wheels
can be made to a consistent quality. The equipment
can be made in a workshop that has competent
metalworking skills and basic tools for cutting,
welding, drilling and grinding steel. It can be readily
adopted and used by other workshops with basic
metal working facilities to produce good quality
wheels at low cost and on reach a small to medium
scale of production.
