P&H 2355

Machinery house of the P&H 2355 Crawler Dragline in 1:28.5 scale.

 

All those of you who think that the machinery house of such a large model mainly features Technic beams, gears and motors, I have to disapoint.

 

The dimensions of 38 studs across and over 60 studs in lenght rather allowed me to include a bunch of details that can be found on the machinery deck of the real dragline.

 

First of all there are two large drums for the hoist and drag cable with their respective motors. Furthermore the two swing transmissions with their motors and finally the boom hoist with its double drum.

 

All the remaining components are without a function for the operation of the model but add the necessary bit of realism:

 

- Two Caterpillar 3512 12-cylinder engines, complete with coolers, air intake and exhaust pipes, each powering generators for the hoist, drag and swing motors as well as for the auxiliary electrical comsumers.

- Various electrical cabinets

- Central lubrication unit

- Refuelling unit

- Air compressor

 

There are four openable access doors to the machinery house, two on each side. Large wall panels in front of the hoist and drag motors as well as on the back give access for maintenance duties.
