Saline Salt Tram November 9-10, 2007

[teotwaki]

Four hardy souls signed up for this trip and have come back with a shared experience that I will attempt to chronicle here. We ventured high into the mountains, braving high winds, 30 degree temps and steep scree covered slopes in search of the history of the Saline Salt Tram.

Rich and I met up Friday morning at the start of the trail, planning to hike to various portions of the Salt Tram that are not accessible by vehicle. Mike and Alan planned to meet us in the evening.

Here is an example of the rugged terrain we hiked that is just part of the 13 mile long tramway


Look at the size of this tower! Almost all materials were hauled by mules, there was no electricity and no power tools.

Note the makeshift ladder on the vertical post consisting of 2 foot wide slats nailed upwards to the top.

Here is Rich near the middle towers of the first photo.

You can see the road we drove down below. Many branches of the road have been blocked by the BLM.

This was a Holy Grail of sorts as we had only seen the shattered remains of these carriers up until now. Realize that this has been hanging here for about 80 years, untouched by vandals. It is fully functional!


The lid can be lifted and latched, the whole drum will rotate to dump its load and the wheeled assembly still rolls on the cable.

Detail of the latching mechanism that pulled the cart along drive cable.

This is how it clamped onto the cable.

Here is the lever side of the mechanism. The large ball on the end of the handle allowed a kick out bar to engage or disengage the clamp. The whole mechanism can rotate within the clamp to allow for steep cables where the weight of the barrel would orient the frame vertically.


End points for mounting that allowed the barrel to rotate.


The end points fit into the mounting points on the hanging frame

It appears that all of the tramway's iron work was built in New Jersey

This label was on one of the barrels that fell off of the cable and we saw similar markers on other hardware. Apparently barrels and frames fell off fairly often, plummeting hundreds of feet.

Cables of the type used on the tramway were called wire rope and Trenton was a very large manufacturing area.

From http://www.wireropedistrict.com/

Iron and steel manufacturing began in the Trenton area around the mid 1700s, providing armament for the Continental Army during the American Revolution.

It was not until 1847 that the Trenton Iron Company (founded by Peter Cooper and his son, Edward, and Abram Hewitt) was functioning, and included a wire mill on Hamilton and South Broad Streets.

In 1831 John A. Roebling migrated from Germany, moving to Trenton in about 1848, when he purchased some acres of land on South Broad Street where his new wire plant would be located.

His main focus was in producing wire for the telegraph, telephones, electric power lines, the newly invented elevator by the Otis brothers and the massive twisted cable for suspension bridges, the most famous being the Brooklyn Bridge, which he did not live to see completed in 1883.

The WIRE ROPE DISTRICT occupies the area immediately surrounding the now defunct John A. Roebling's Sons Company complex. It borders the Chambersberg Italian District, famous for its fine Continental and American cuisine, on the east the East State Street Redevelopment District, on the south, the Mill Hill District and the Capital South District on the north, and the Riverfront District along the Delaware River on the west comprising the area between South Broad Street, Hamilton Avenue, South Clinton Avenue and Dye Street, roughly an eight block parcel of land which was the site of some 44 Roebling industry buildings.

It is now the hub of a major area redevelopment effort, retaining as much of its vintage mileau and charm, yet in a somewhat more modern setting

By the time Rich and I finished checking out the western tram towers it was getting dark and we headed up to the top to stay in the old tramkeeper's cabin. See pictures and details from a previous trip

Rich's wife had prepared some super carnitas, salsa and salad for us. As the wind howled outside we enjoyed a hot meal and Sam Adam's bottled beer along with chocolate cake. By 8 PM we had turned in. Around 10:30 Alan and Mike made it up safely having traversed the ridge route in the dark. By then the temps in the cabin were 34 degrees. My Engel Fridge readout said that inside the truck it dipped to 31 degrees.

Saturday morning was the start of the long hike to the more remote towers.
Here is Rich pointing out the finer details of the first one that we hiked to.


This hike would include descending 2500 feet, bushwhacking and trailfinding, dry rocky waterfall climbing and a few surprises.

Here is Mike inspecting the timbers


While Alan climbs up for a closer view of a grease bucket hanging on a nail just as it was left when the tram shut down.

Note the large box of rocks used to counterweight the cables

Got it!

Using rock quarried nearby these large boxes provided the necessary tension for the cables. Made of timber, they had large iron rods that fitted to large hooks at the end of a massive chain that was in turn fastened to the cable that ran across a wheel.







There were a number of these counterweight stations in the tramway with one box for tensioning cables in each direction of travel


We saw places where the box needed more room to pull downward so the workers had to excavate large holes beneath the boxes.

Incredible shots!!! What a great adventure! You were just in that general area last month right? Life is good for you Jim!

[Willman]

Sweet old place!

Love the pictures and the write up!

Here it is, the mid control station at 6000 feet. The view is looking back up to where we started at 8700 feet. To the left are the heavy gauge power lines that were installed later when the gasoline engines were replaced. On the slope to the right are the remains of the living quarters.





This control station was only missing the large leather drive belt but the motor, gears, clutch, speed governor and disc brake were all there.

Mike in contrast to the size of the 5 to 1 gear set


Behind the large output gear is a manually applied brake made of a large leather band tensioned around a drum by a lever up above the planks


The large clutch assembly that applied curved wooden pads to the inside and outside of a drum.

Behind the clutch can be seen the large disc brake that was controlled by a mechanical governor assembly.

Spare clutch pads!

[teotwaki]

The governor that controlled the disc brake below it in the motor drive pit. The rods that go down through the planks applied the brake pads


Alarm or Signaling Bell?


Large cable drive wheels were spun by the cable seen to the right of the large gear set in the drive pit photos in the previous message


Tools everywhere, some still neatly hung on nails

Jim,, excellent write-up, and history lesson. Thanks
