Ch Check eck

  • Prototype with headrest and

ergonomically tested. Check:

  • Makes the piligrim sleep.
  • Increased weight
  • Hits the porter when bringing the

palki down

slide-39

Co Comprehensi mprehension

  • n
  • Weights- ranging from 38 kg to 70 kg.
  • Porters are required to trek for 28 kms in a day uphill

and downhill

  • They usually take 4.5 hours for one way taking breaks

in between.

  • Due to heavy load on shoulder, they shift the

palanquin bar from right to left shoulder and vice versa after every 2-3 mins.

  • After every 5-6 km, the porters change their respective

positions

slide-40
SLIDE 40

Co Comprehensi mprehension

  • n
  • Should reduce physical strain on the

porters

  • Should increase porter comfort and safety
  • System should not destroy the current

livelihood of porters
