Hello everybody.

My name is Nestor Salazar. Am a new operator from Sweden. Am gonna finally purchase my first rig :D and I been looking for an arm. I have seen one but I heard thats something wrong with it. I just dont now how much problem that is.
I have attached some pics for you to look at. Hope you guys can see in the middle of the picture, inside the springs. like something is stuck.

My question is

- Is this a problem / can it be fixed, were and how much will it cost.??

Ive heard that they have tested it and it works fine. But it makes a clocking sound when you boom up or down.!!

- Another question that I have is how much this arm carries.?? As far as I now its a master arm.??

Hope somebody can Answer my questions.

Kind Regards

Nestor Salazar Manriquez

Looks like a collar from a spring got dislocated, it scratches against other parts and also I see a strange curve in the spring........ I suggest a serious check by an experienced operator and then very likely a good check/repair at Tiffen.

This might be not the only thing wrong with it, depending on the age. This Master arm can have other issues as well (hair-cracks)

The scratched part looks like a Delrin (plastic) collar/guard and guide that should be clamped around the chome ring on the right of your pix. It's a pain to do this, BTW, so I suggest you contact Hofmann Technik and have someone there take a look at it.

Most likely it's not a big deal, but since someone used it like this, it should be examined, along with the springs, cables,... well, everything.

I suspect you have an arm that lifts between 40 and 65 lbs (20 - 45lbs "payload" with a 20 lb sled).

The curve in the spring is probably from the collar being displaced and the arm collapsing more than normal.
