Mechanical Projects Abstracts
This Mechanical projects presentation is a model and a simplified version of Kattwyk Bridge and has been made under the constraints of space, time and resources available in the lab.The Bridge mechanism has been divided in three sections.The central section lifts above,while the two side parts remain intact with the supporting angles. The lift mechanism used for the bridge is based on the pulley system involving three pulleys. A string is passed through the two pulleys on either side of middle section and the pulley at the center synchronizes the motion of two pulleys and makes the motion centralized.

The angles are used to restrict the motion of central section allowing only the motion in vertical direction to occur and provide the stability to the bridge structure. A chain is also used to stop the central section at any desired height depending on the height of ship assuming a real case situation thus saving the power. The mechanism used to lift the central section is due to the constraint of not using any electric motor or gears. In real case situation, the power can be given by electric motors and cables can be used. The four bridge supporting angles that connect the three sections of the bridge will actually go till the bottom surface of the river.
Motivation behind the Mechanical Projects
The motivation behind this Mechanical projects Presentation Topics is the KATTWYK BRIDGE, HAMSBERG, GERMANY. The bridge was built in 1972. The bridge has a unique feature that it based on the “Vertical Lif t Mechanism”, its middle (movable)part lifts to give way to the ship passing by thus maintaining waterways transport. Till now no bridge such has been built in India.

HI sir i am impressed with this this project i would like to take this project for my 3rd yr mini project the oly doubt is wats the use of the chain hanging over there and is there any other way to contact u…..
its bridge and the bridge can be lift upwards for the passage of ships…thats the use of chains…when the ship moves under the bridge,with the help of chains the bridge again making passage for the road vehicles..hope you understood..
sir i hav also interested to do this as my nini project…………. and pls tell me wats the exact working principle and is the pictur that shown above gv me sme dbt sir the part behind the bridge that shown in the pictr is in working???????? pls gv me the solution
admin,im doing 3rd mech …im interesting in doin tis project. can yo send me all info and fabrication abt tis project to my id pls i want it soon…..18logesh@gmail.com
hi sir..can u post photos of this model in various angles?
I have done this one as my Engineering mini projects and i got a very good remarks from my professor..Thanx to Site admin
I’ll immediately clutch your rss as I can’t in finding your e-mail subscription link or newsletter service. Do you have any? Kindly allow me know so that I may subscribe. Thanks.
Airline valves available sizes are M5, 1/8, 1/4, 3/8, 1/2.
sir..i just want to know the pulley is hand operated or automatic………and can we use ball bearing mechanism for this ….and how does the pulley exactly works
This is an extremely well written article. I’ll make sure to bookmark it and return to read more of your useful information. Thanks for the post. I will definitely comeback.
sir can i get the full report ??? iam so impressed sir…….. can i get a detailed report???……… please sir its urgent………… hoping good from you !!!
sir, what type of cables used in this project and what type of pulley is used for this project
if you don’t mind please tell the full details about your project ( material name and dimensions,pulley size )
