This document presents a project proposal on gravity ropeways. A group of 4 students will study gravity ropeways under the supervision of Mr. Hemant Chauhan. Gravity ropeways use gravitational force and pulley systems to transport goods and people up and down slopes. The presentation will cover the objectives, introduction, terminology, operation principles, calculations, applications, features, impacts, and recommendations of gravity ropeway systems. It will rely on references from previous studies on aerial ropeway technologies and experiences.

 Objective
 Introduction to Gravity Ropeway
 Why it is Important?
 Major Terminologies
 Operation
 Working principle
 Calculation
 Applications
 Features
 Impacts

3. Gravity Ropeway
 Gravity ropeway is simple mechanism of rope and wheel.
 Rare and restricted to unique and often challenging context, but an
effective solution.
 Gravitational force is most reliable, spontaneous and never ending source
of energy and it’s free.
 Gravity ropeway operates under principal of gravitational force without
any external power.

5. NEED?
Rare and restricted to unique and often challenging context, but an effective solution.

6. Major Terminologies
Support cables or track ropes:
o Provides support to trollies
o Attached in two different towers
 Supporting tower:
o Steel or concrete structure at upper or bottom station
. o Absorbs possible thrusts
 Pulley :
o Provides motion to load

7. Major Terminologies
Station or platform:
o To land trolley and goods
o To place supporting parts
Hand brakes:
o Wooden brakes at bottom of station to control velocity of moving trolleys.
OR
o Manual brakes using safety rope within trolley

8. Operation of Gravity Ropeway
 It is a pulley system, simply ropes and wheel.
 A trolley , rolling over two separate supporting steel wire ropes suspended from
two separate towers (different altitude).
Reload wire ties around a pully system at higher altitude extremity to bring back
the trolley.
 A hand brake can be integrated with flywheel or a manual speed control rope can
be attached to control the landing speed of the trolley at the bottom-station.
 Loaded trollies at up-station is pulled downward by force of gravity.

9. WORKING PRINCIPLE
Fig 03 : Forces on inclined plane

10. Air Drag (Friction here)
In aerodynamics, drag refers to forces that oppose the relative motion of an object
through the air.
Drag always opposes the motion of the object and, in an aircraft, is overcome by thrust.

11. CALCULATION
Using Pythagoras theorem
𝑎2
+ 𝑏2
= 𝑐2
15.39 cm 41cm (41)2
= (38)2
+ (15.39)2
Now using 𝑡𝑎𝑛𝜃 = 15.39 ÷ 38
𝜃 = 22.09°
38 cm

12. APPLICATIONS

14. Features
 Cost effectiveness
 Time saving
 Short route
 Energy efficient
 Environmental friendly
 Simple technology
 Nominal operation
 Employment
 Low transportation cost
 Community involvement

15. Impacts
 One step financial solution.
 Income of villagers increased 3 times.
 Linking opportunities.
 Escalates school attendance.
Transportation cost reduced to 85% (data).
 Time saving.
 Increase market capacity.
 Direct and indirect employment opportunities.

16. Recommendations
 More research and development required to improve the technology.
 Involvement of local community, private sector, local as well as central government.
 Development of national policy about the technology.
 Introduce insurance policy in ropeway.
 Emergency treatment services and safety considerations.
 More participation from development partners required.
