BUCYRUS ERIE 50-B

STEAM SHOVEL

Conclusion - by Alberto Celot

I built a cage to lift the revolving frame, which weighs 54kg.

Then I finally got to see the result of my work.

We begin with a series of views with the cab removed so you can see all the mechanisms:

The ‘Boom’ has two ties on both sides laterally to stiffen the structure; one is rigid and the other is made with steel cable. The first picture below shows the connection of the cable at the upper end of the Boom; after passing into the throat of the support, the cable through the Boom and is fixed on the opposite side. Under the two pulleys you can also see the connection of the cable for lifting the bucket.

The second photo shows a front view where it can be noted that the axis of the pulley of the bucket is rotated to ensure that the two ends of the rope are spaced at the same pitch as the two upper pulleys:




















































More views:

The first of the following photos shows the winding drum of the hoist rope and bucket, bottom left, winch for lifting and lowering of the Boom. The other two photos show the operator’s position with all levers and foot pedals.

With reference to the last photo, the commands available to the operator sitting on the seat are:

A - Lever's Main Engine (pushing forward) and steam clutch (inserted with lever upright and off with lever moved laterally inward

B - reversing lever of the Main Engine

C - control lever of the Swinging Engine. With lever in the centre the engine  is stopped, pushing forward the Revolving Frame rotates counterclockwise, while pulling back rotates clockwise

D - control lever of Thrusting Engine. With lever in the centre with the engine stopped, pushing forward the sliding arm Dipper Handle moves forward, while pulling back the arm moves backwards

E - lever for engaging the winch for lifting and lowering of the Boom, actuated by the Main Engine

F - Lever for the insertion of tracks traction, actuated by the Main Engine

G - Brake pedal of the winding drum of the rope for lifting of the bucket

H - Blocking of the brake pedal when it is in the braking position

I - Pedal to control opening Bucket door

L - Shut-off valve of  Swinging Engine

M - Shut-off steam valve Thrusting Engine

Also behind the operator is a valve to shut off the steam to the clutch.

And now two photos of the transmission to the tracks and the combustion chamber with the burner.


Gears and the support carriages for the rotation:
And finally with the cab in place.
