Chapitre 95: Installing the turbine (3

Just like that, the fasteners continued to connect the round steel one after another and when they reached at a distance of 20 metres horizontally, the falling waters were so powerful and this was the moment when the turbine was let down.

Slowly by slowly the fasteners had to pull the huge turbine across the railings to that they could fix it where it was needed.

Nonetheless, before the turbine could be set up, Virtya had asked the fasteners to substitute the single strand sprocket of the turbine with the spur gear. A sprocket would not be effective when it came to the gear system and that was why Virtya had to make this last minute decision even if he knew that doing that might not be possible especially where the turbine was at the moment.

But the fasteners showed Virtya that they were not there for show as they quickly unfastened the sprocket and in its place, a spur gear was set up. This spur gear connected perfectly with the hub of the turbine so that when the turbine moved, it would move this gear.

One should know that the diameter of the newly set up spur gear was simply the same as that of the previously set up single strand sprocket.

Anyway, it was not easy to fix the turbine and the fasteners were needed to be helped by the other workers to hold the turbine in place so that it didn't got pulled away by the forceful waters.

Painstakingly, just like how the fasteners did with the round steels that they were fixing across, they installed the smaller end of the axle onto the bigger end of the round steel on the left and then the nuts and bolts were used to fasten these ends together.

However, due to the presence of the steel blades, the workers were not able to use a tee shaped round steel to hold the turbine onto the horizontal H beam that lay accross the undercutting, therefore, the fasteners opted for using steel plates which had a semi- circular shape. When two of these semi circular steel plates were placed around the end of the axle beside the spur gear, they wrapped around the axle perfectly. It was the presence of these steel plates that enabled a round steel to be fastened onto the axle and then the other end was connected onto the horizontal H beam.

Just like that, the other end of the turbine was also connected to the horizontal H beam.

At this point, the fasteners faces were pale and some red marks could be seen on there skin because installing this huge turbine was not a joke.

If not for the presence of a braking system that stopped the movement of the turbine when it was being installed, the fasteners wouldn't have installed this mechanism because the pulling force of the waterfall would have rotated the blades and pulled the turbine towards the plunge pool.

The fasteners didn't release the brake of the turbine but instead, they continued to fix the rest of the round steel that connected the axle of the turbine onto the horizontal H beam and the exposed vertical H beams on both sides of the bank.

Lastly, the fasteners had to firmly and perfectly fasten a slightly smaller spur gear under the bigger spur gear of the turbine. This smaller spur gear fit perfectly to the teeth of the bigger spur gear and when the turbine would rotate, it would basically transmit the rotation motion to the smaller spur gear through the bigger spur gear. This smaller spur gear would be rotating a long round steel bar that was held in place by T shaped steel. Of course, the holders of the round steel bar were fitted with bearings so that they didn't hamper the rotation of the round steel bar. The round steel bar ensured that the rotation motion was transferred horizontally to the west at the bank of the waterfall.

The rotational motion was transmit through the round steel bar of to a sprocket which was fixed upon an I beam at the bank of the waterfall this morning.

Now, the foreman asked the workers to take out the extra long and heavy round chain.

This chain was then fixed around the teeth of the sprocket and then the other end of the chain was wrapped around another single strand sprocket that was installed at the steep surface of the rift valley.

The foremen had to use three roller chains until the last chain fixed upon the duplex sprocket that was at the cement plant.
