Engine hatch rams

[stefan_r]

I have some Ultraflex Control Systems hatch rams to lift my engine hatch on my Sunseeker Superhawk 34.

They have failed and I am now after something new, as these rams seem to fail every four to five years.

I have no idea what the hatch weighs....but it is heavy, almost too heavy to lift by hand.

Any recommendations?

Bennetts (as in trim tabs) do a range of rams for this application - trying searching for Bennett hatch lifter rams, that should get you started.

Lenco do an electric ram just a longer version of their trim tab ram (except this one works for more than two years!)

Just a thought.......

Some years ago I wanted similar things & managed to get some from a local car scrapyard at a couple of pounds each. I'd guess the weight of a car tailgate might be similar so if you're lucky...

The Bennetts ones use the existing hydraulic pump from the trim tabs and are an easy modification.

Unfortunately not....suspect the hatch weighs about 100kg....maybe more....

If you don't mind the cost, these actuators are the best you can find.

Niiiiice. And not that expensive compared to Bennett which is current favourite.

More investigation needed...

Does anyone have a non working lenco trim tab? I am looking for a cog for one.

Thanks

I'm sure I will change another set soon.

Any good?

Start by checking if the original data is stille visible on the old ones. They do come in many sizes, specs and materials (even stainless).

Go for the same force as the original unless you want to alter the geometric design.

I used Alrose Products - www.gas-springs.com recently, very good. They had supplied the originals on my Fairline Phantom.
