Hydraulic Silhouettes

I've noticed this a lot on my travel around Taiwan and every construction site or builders yard I go past all have the Cranes, Cherry Pickers or Fork lifts, with the hydraulic arms extended out all the way. Which is an odd thing to do, because over time the pressure naturally weakens from the hydraulics forcing the arm to come down any way.

Plus for a country which received a lot of rain, especially in Taipei it would make sense to cover as much of hydraulic arm from the natural elements as you can, maybe it is an odd safe saving technique.

When I find the correct photo I'll change it!

It is quite an interesting site when the sun goes down as and all you can see are the silhouettes of platforms or digger buckets behind an orange sun, not that this photo is the best example above as these are cable Cranes.
