Thanks so much for posting that information I have a 1970 HI LO gave to me and i am learning. I am a green horn at this. Thanks so much
HiLo trailers are made to collapse and should never be towed in the up position. It is okay to use 2x4s to support the unit on the outside if it will be in the up position for long periods of time. This takes the slack off the cables. It should lower gradually and will not collapse on you unless a cable is broken. Other with 70s HiLo can explain how to lower it.
Hi Sam,
What would you consider being up a long period of time? I've had mine up since I purchased it about 6 weeks ago. Is that a problem? Doesn't dropping the top half onto the locking pin relieve the pressure on the cables?
Thanks,
They were designed to stay up. The safety catch is for when something happens to the lift system, such as, cable breakage or the hydraulics fail. If properly maintained it shouldn't be a problem. I would say that if you aren't using the trailer it probably is be better to put it down to relieve the weight off the components.
