    Help
    I am still in bed after my 3rd back operation
    I have been caravaning since 1997 and have a 2016 Sprite SW
    It became extremely difficult for me to lift the roof befor my operation
    Is their any “cadget” availzble to assist in this matter or must i kiss my pop roof caravaning goodbye

    Maybe replace the gas struts with stronger one’s. I’m going to replace mine with 500 nm strength. This is for a Gypsey Regal. Sourced from McNaughton’s in Pinetown.

    Hi

    What is the strength (KPA) needed to lift the pop up roof ?

    Will 10 KPA do the job or to strong?

    Hi, See my earlier comments. I think this depends on the size and weight of your roof. I have a Gypsey Regal and first tried 450nm which was to weak, I then took them back to McNaughtons and had them pumped to 500nm. I feel I could have gone to 550nm. But 500 is working fine. I hope this helps.

    Hi Jannie,

    This is a very old post but do you perhaps have the size you bought for your Regal. I also have a 2001 and need to replace the struts.

    Thanks

    I notice the force of the gas struts being quoted here in ‘nm’. This is incorrect. The force from gas struts is a linear or straight line force and is measured in Newtons.

    Nm is a rotational force or torque measured at the end of an imaginary 1 metre shaft set perpendicular to a rotating axle such as a crankshaft

    To find the gas strut force required to raise the roof you need to know the weight of the roof.

    Since there are 4 struts that will share the weight equally you can then divide the weight by 4.

    Since the struts will only rise to an angle of about 45 degrees you multiply this weight by 1.414 ( sin45).

    Since there are 9.8 Newtons required to lift a single kilogram you now multiply by 9.8.

    Since you need to build in a margin for under performing struts you now multiply by 1.2.

    Now you know what to get your struts pumped to in Newtons not nm.

    Good morning Barend

    Our company supplies to the manufactures in this sector a product called Linear Actuators. This in many cases can replace the actual gas struts/ gas lifts in the caravan setup and assist the client to automate many functions [ example: roof lift system, roof tent lift, caravan bed lift or slide, leveling of caravan].

    These actuators works either on 12Vdc or 24dc.

    We do require some information from you regarding the weight of the roof, the lengths required to open etc…

    Unfortunately we as Linear Actuators South Africa only supplies to the market and is based here in S.A. You would then need to get your manufacturer or a service repair agent to install/modify it for you.

    Please do visit our webpage: http://www.linact.co.za for more information.

    What would be the approximate cost of each linear actuator, say the 12V job with a stroke of 300mm and a force of 600N?

    The units suggested by Mr Erasmus look abit like the Duff-Norton LT series from North Carolina, USA, which retail there for about $220.

    Experience tells me that $220 becomes R5000 to R6000 once the import and local markup are factored in.

    Which makes them a bit of a hard sell when the gas strut they replace costs about R200.

    Also, the gas struts are housed under the fringe of the pop-top, between it and the hard shell. A linear actuator would not fit there even if it didn’t have a motor making it even wider at one end. So huge radical surgery would have to be performed.

    And then there’s all the wiring and control switchgear to consider…..
