Heyl & Patterson used to have a brochure with some vintage waggon tipplers and similar illustrated by photographs and excellent pen or charcoal drawings.

They might still have a few lying around; the one I had was printed in the 1970's at the latest.

If you are near a port there might be a maritime museum you can search in. Much of our business involves port works and it is surprising what shows up in libraries attached to maritime museums.

Not much but it might provide a couple of pointers. ■

At Heyl & Patterson we have some old literature in our achieves, but do not have enough available to provide copies. Heyl & Patterson was founded in 1887 and has been making various railcar unloading systems for a long time. Some of our earliest dumpers were for the mine industry and dumped mine cars.

For a fun video of an 1897 railcar dumper you can view it at http://www.youtube.com/watch?v=Z0br89U8K-U. I do not know if this is a Heyl & Patterson machine. This was an early design.

Something old, something new, something borrowed, something blue.

Well here's something old

Dear Shri A. K. Banerjee,

You have stated about the history of development of wagon tippler. This is a very big question and I think it would be difficult to get the information readily about this from A to Z. It seems this equipment might have originated in U.K. and in that case British railway very old document might have information about the who asked the permission first to install such equipment, and thereafter there must have been development about technical rules and regulations for such item.

As far as India is concerned, people were using this equipment at least before 50 years. In those days buyers were readily accepting Strachen and Henshaw make wagon tipplers. This equipment started getting introduced in power stations and other industries in a big way after Elecon entered into collaboration with them. This is evident from the number of installations in this country till today. In those days, wagon tippler of mechanical clamping type were common. The side discharge type wagon tippler having about 8 to 10 tips per hour became very popular. The rotary discharge type tipplers were used less frequently. Those were the hay-days for side discharge type tippler in-haul beetle marshalling, out-haul beetle marshalling etc.

In those days the aforesaid unloading rates were matching to the need for the power station capacities (coal based). Subsequently number of tips per hour, continued to increase in pace with the bigger size of power station.

In those days large steel plants came up with the help from Russia, Germany etc. These steel plant were possibly having wagon tippler system as per the original source. Thereby people in material handling also became familiar with such systems and their comparative application, values and performance.

The aforesaid information is as per general observation and inferences. It need not be construed as an formal documentary type of data. Other people can add information from their side. The other countries in those days will have popular type and make as per their industrial setup and other reasons. As for the recent history, you will be well familiar with the subject.

Hi every body

as i am student of ME Mechanical Machine Design and now days i started my project on design or optimization or modification or analysis of wagon tippler

please help form where i can get referance of use full books for further reading or kindly person who can help me for my project work

Dear Shri Nikhil,

I have a good experience about wagon tippler installation however, it would not be convenient for me to involve in your project because it will be too demanding and time consuming.

I suggest you to write to wagon tippler manufacturers to obtain their marketing literature which will provide all the basic information about the type of wagon tipplers, their basic operations, the product application range and other important information about such installation. Their names you might be knowing. Subsequently, you have to convert this information into your project need which can have a stress on different aspects such as design oriented or application oriented or commercial oriented etc.

Trust the information might be of use to you.

Regards,

Ishwar G Mulani

==========================================================

As a previous seasonal laborer in a power plant I can recall an incident where a permanent employee was crushed between the car couplers due to carelessness of the remote control locomotive operator. The young boy died a few hours later from the injuries and to this day 32 years latter the operator denies any responsibility for the accident.

The way the rotary dumper was installed due to the systems location being next to the main rail line at the time being 1945 was a problem that was recognized and not addressed prior to construction by simply moving the rotary dumper /tippler building closer to the the hill side and moving the passing track inland in relation to the movement of the tippler building.

Moving the location of the rotary dumper tippler building would have allowed the linear movement of empty coal cars after dumping rather than the current practice being one of

constantly manually repositioning the individual rail car knuckle to connect with the previous empty coal car due to the curvature of the exit track which paralleled the main track which at any speed did not allow the cars to reconnect and quite often derailed them due to the radius of the curve exiting the rotary dumper/tippler building.

If the system had been designed as a multiple car dumper the curve would not have been placed behind the car dumper due to the main line and been linear in its path

There is not much modifying, optimizing or improving the design of a wagon tippler as it uses gravity to its full advantage- if the cargo is not frozen to the hopper car. Hence the reason for warming sheds using resistance heaters to heat the cars and payloads prior to dumping them.

The bathtub gondola cars we today have rotary knuckle connectors on one end and allow the car to be swiftly dumped and returned to vertical while still connected to one end of the rake/unit train-but that only works with the more modern car dumpers designed around the rotary coupler system to use them due to the car design and longer length-and you cannot use the rotary knuckles on these cars with the short length dumpers designed for the 80-100 ton-forty to fifty foot gondola cars.

=========================================================

Belly dump cars are no different as they are shook, and flame heated to break up the coal to drop it to a plow conveyor and have to have the coal pushed through /jack hammered through the dumping doors.

==========================================================

Even still the the coal has to be jack hammered to pass through the grizzly

under the rotary dumper to the belt feeder and transfer point and still does simply from the nature of the material, weather, moisture and temperature.

Improvements have been made in regard to car movers such as the WR Stamler rail car mover which utilizes a hydraulic drive system with sheave blocks, wire rope, and pusher blocks attached to the sled to move the rail cars individually or in unit trains in position for what ever purpose be it loading, unloading etc The pusher blocks drop down to allow passage of the rail cars and the timing of the wire rope and sheave blocks and pusher block allow it to drop down retract and raise back up in the area of the next wheel set to continue pushing the car or cars forward. The in rail bed car mover is properly situated to travel the length of a rail cars wheel sets to move it in position for loading and unloading and is either remotely controlled or manually controlled reducing human contact to a bare minimum.
