New timber trailer advice

[Brushcutter]

I haven't used a forwarding trailer before. Could you tell me what makes the standard timber cranes more versatile than the parallel ones?

 

Parallel cranes work well in clear fell where the movements are limited because its clear. So they're very quick because the parallel action keeps it smooth and quick. The actions are kept parallel by the extra boom part. As you lift higher it dips in saving time and effort.

In thinnings especially where there are lots of trees staying behind its easier to do more of the actions yourself ie as you lift the crane doesn't extend it self. Makes it easier to thread past and around trees and past anything that maybe in the way.

 

Obviously you get use to what you use. I've used both and prefer a non parallel crane for forwarding but wouldn't be without one on a harvester. There is a weird telescopic crane that is neither one or other that i'm also not to keen on.

 

Poorly laied out timber that takes a lot of headboard/load bumping to square up works better with a parallel, however penciling works better with a standard. I'd imagine chipper feeding would be easier parallel too.

 

Mowi i think do exclusively parallel cranes, Kelsa,Vreten all have one in the range from memory. You mainly see non parallel cranes though.

 

It's really just a preference thing at the end of the day.

Thanks Brushcutter, that's very helpful:)

An important and often missed out point is matching the trailer wheel space/width to that of the tractor pulling it. You will need considerably more power and make some horrible tram-lines when they don't run easily behind.
