last weekend, I found a toy which is belong to my brother’s son in my grandmother’ house. It is a Fire engines, and it has a adjustable Fire ladder，then I want build this things with maya, so bra bra bra ......the modeling is done, and then the problem comes out when I ready to rig the fire ladder, please look at the pic below, let me explain:

1.there are three axle in red : A B C , blue things is base of axle
2.the green thing is the fire ladder
3.the yellow thing is a hydraulic push-rod which can be adjustable
4.the pink thing looks like a Skateboard, and hydraulic push-rod base on it.
5.the gray thing is a part of fire engines’ body.

there is no problem if it has a fixed pole instead hydraulic push-rod, because I can just use a IK handle link A & C, but now....it doesn’t work

is there anyone can help me?
