Bicycle ambulance
Practical Action
Its construction is uncomplicated as the required equipments are easily available in the
markets of Terai.
It can be constructed easily even at local level.
The technique is very easy for its handover.
There is no requirement of any fuel and uses high number of local labours.
3. Essential equipments for bicycle ambulance
3.1 Clamp system
Front part of the cycle and the lower frame of the bicycle
ambulance is joined with the help of clamp. Two M.S. Flat is
attached with the carrier of cycle and is tightened using a knot
bolt. To avoid any difficulty for the patient while turning the
handle of the cycle, a ball joint is used in the upper clamp
which makes it easy to turn the cycle. Ball joint of cylinder
shape with 40 mm radius is joined by welding it to M.S. Flat.
Following are the elements required to construct a clamp
system:
Knot bolt of 10 × 60 mm- 2 pieces
M.S. Flat of 215 × 40 × 40 × 5 mm- 1 number
M.S. Flat of 190 × 40 × 5 mm- 1 piece
Ball joining system of 117 mm height
Knot bolt of 12 mm
3.2 Braking System
Braking system is used to balance the speed and to have complete control at the time of
emergency. It uses a cylindrical pipe of 45 mm radius. At the later end of the pipe, a 25 mm
knot bolt is used to fix a spring inside the pipe. In the middle of a spring of size 3×22×50 mm, a
4 mm thick M.S. Flat is used to avoid it from losing its working capacity. When a driver uses a
break, the Guide shaft enters into the cylinder which causes the brake wire to stretch. This leads
to the contraction of brake lever. And finally, the break shoe holds the ring of the wheel which
eventually controls the speed.
