Hi, I'm wondering if NCARB distinguishes between a "Hole-less Hydraulic" and a "Telescoping Hole-less Hydraulic". This practice exam question would lead me to believe that no but theres been so many errors in their practice exams I'm not sure if I should take it at face value. Should I always assume Hole-less is telescoping unless it says otherwise? Thanks!
My understanding is:
Conventional hydraulic - Max 60' travel
Hole-less hydraulic (no telescoping piston) - Max 20' travel
Hole-less hydraulic (with telescoping piston) - Max 40'-50' travel (different references have different travel distances and I'm not sure where NCARB is getting 40' from)
Roped hydraulic- max 60' travel
