I must forewarn you that this model is the crane I first learnt to operate in and got my licence on, an maybe I am a bit bias but they are great!
Most of these cranes are set up without the cabin for remote operation only and for good reason. Only a lunatic would drive a 5t crane from a cabin, they deflect so much you would be sick in no time.
It has a few shortfalls I must admit: max lift at 50m is about 1 tonne, the hoist is fairly slow, it needs a slower speed for the trolley and it has the worlds worst hook block; it is a kite. Its flat and wide and catches every bit of wind, I don't know what they were thinking going with such a terrible design.
The hetronic remote control is just to big, its about 4 times larger than the standard remote controls used by most of the other tower cranes, expect to bang into things constantly with it.
But faults aside its a good machine for the right job.
The crane is very responsive, much more than the other popular 5t remote out there from Comadil (and wont break down:) They are very durable, most are rentals and they can cope with not being treated properly and keep on going. Also for a small crane it performs quite well in the wind... well except for the hook block.
The Potain MC 88 is a good remote control crane for the very common smaller jobs that are all over Sydney at the moment, which explains the cranes popularity.
I give this crane 4 out of 5.
