Up on the Black Birch Range (1700m) Telecom have a hut containing various radio telephone (RT) equipment for other companies including service for police, ambulance, DOC etc. With the unusual snowfall on Monday night, the overhead powerline, much lower down the hill, couldn't handle the ice load, breaking some of the lines and cross arms on the poles, thus mains power was lost. The battery capacity is only designed for short term mains outages as there is a diesel generator on-site which should start automatically. It didn't.
Further down the hill at 1400m is another Telecom site for telephone service for most of the Awatere Valley. This also lost mains power and the batteries failed shortly afterwards. They should have lasted more than 24hrs. Their mission, should they accept it, was to fix it!
They first tried to drive up but got stuck in snow at only 500m up :-? .
Next, they got to fly in a helicopter to the lower site but it coould not shut down as the weather was likely to change and the cloud ceiling was almost at that level. It lifted 4 batteries weighing more than 80kg each close to the site for them, along with tools, so they could temporarily connect them to the system to get it operational. The pilot warned them that if they heard the helicopter rev, to stop everything and run because as soon as he got the engine up to speed he was lifting off whether they were on board or not! :lol:
The first problem was opening the door of the hut as the locks were frozen. They couldn't get to the higher site due to low cloud so went home.
Next day was too cloudy for choppers so they got a digger to break a path up the Mt. It took them 4 hours to do 8km :roll:
Then it was too dark to see the road so they had to return home until next day.
Today they headed up again and eventually got to the top site about midday. It only took 2hrs to do the final 3km.
There are more shots here
This is ice formed on a waratah
