winch for rib, what is the calculation for the approx weight up a slope? - Page 2

found this, seems useful

Have a look at T Max there seem a lot about and they are cheap, however, I have no idea how good they are.

T-Max

Been thinking of one for my landy, I liked the crossmember job in the picture so elecy one at the back and hydraulic at front - that should do it - for a price!

How about going for a Powrlaunch instead? www.powrlaunch.co.uk

I reckon that a winch on the motorhome would be a cool toy, but a complete pain to use in practice!

40 deg slipway

Wouldn't fancy anyone's chances on one of those.

Try winching at full load with an electric winch with a dead engine and see how far you get

anyway as already commented, relevant only to 4x4s parked in the middle of a river

yes an electric winch will be perfectly capable, bearing in mind my comments on ratings though. I have had 2 electric winches before I switched to hydraulic and they have all had a thorough work out, each had their pros and cons.

The link Hugh just posted reminded me of something else to bear in mind: most winches "rated load" is with the wire on the first layer of the drum and it decreases considerably when there are three or four layers on the drum, so with the drum full the pulling power is considerably less. Another reason for slightly over-specifying the thing in the first place.

Hand friendly rope: magic stuff, I use that on mine. I'd never go back to wire again

even if the price is a bit

Powrlaunch hmm interesting and novel idea but I do wonder how long an electric motor will last operating in salt water?

T-max are ok but apparently (the 4x4 ones anyway) very hard to get bits for if you break it. Warn and Superwinch on the other hand, easy to get bits for even old ones. I've got a T-max hand winch for a backup, it works fine but its a bit like rowing a RIB with oars, you will get there in the end but it takes forever and it's #kin hard work!

I doubt whether any slipway would be more than about 20 degrees, it doesn't sound much but it is quite steep!

I am in the process of fitting a capstan winch to the front of my Defender. Has a nice 250hp V8 to power it direct. Great if you need to drag a trailer across a sandy beach - you are only limited by the length of rope you have - 300' in my case.

For self recovery I still swear by my Tirfors - awesome power and so much control - just VERY slow!!!

How many slipways are actually that steep?

My guess is that most are no more than a 1 in 5 slope (20%), which is less than 10 degrees.

Might be worth actually checking some before making a complicated calculation based on worthless base data!

40 DEGREES!

Five more and it would be 1 in 1, thats "seeing sky" steep!

Hugh Jardon · 06 September 2006, 15:21

some slips have various angles on them so for me the assume the very worst case of 40 degrees and get a winch that could handle that and we are home and dry, also if a 20 degree slip but over rocks and awkward surfaces then the load would equate to more

i prefer to use the mh where we can, then to use ropes as an alternative but also a winch may be good where a rope would not work, all very tricky with the size of mh but we will see

easy thing would be to have beer chits ready and tap a 4x4 owner on the shoulder and ask afavor

I fail to see where the 'pain' factor comes in. The main problem with recovering with the motorhome will be traction. If you were having problems, you would be able to position the motorhome above the slippery section of the slip, hook the winch to the boat trailer and winch it up above the green shit. Chock and brake the trailer, drop the van back and hook the boat on. Pulling a Rib up a made slip is gonna be a doddle compared to dragging a Landie out of the mire, so a half decent electric winch should suffice.

Just get a peice of rope and stop this bickering at once!: http://www.jimmygreen.co.uk/

Hugh Jardon · 07 September 2006, 22:13

getting some nice 7.5 tonne ropes made up by that nice man on ebay, and will get different lengths for different situations. i think the 4.5 tonne winch i identified below is the best one and ample for the job but we will see on that

thanks for the feedback and advice....much appreciated

Rogue Wave · 07 September 2006, 23:00

I have a husky 8 it's pretty robust but needs to have it's own battery but to be honest I nearly always use a rope

250bhp? You've done some serious work on that V8 to get it to that power output!

Yup - am hoping for 300 though!!!

ok took delivery of me new tow ropes today,
they are all 7.5 tonne with galvanised steel thimbles on each end with 10.5 tonne steel shackles
one rope 5m, the next is 10m and the third is 20m giving me rope combinations of 5,10,15,20,25,30,35m on a slip which should be perfect

they are also for the motorhome if that should get stuck somewhere and for the 4x4 etc

got a great deal from dave at euroropesuk on 0191 296 5895

the whole lot delivered was 75quid which is a bargain in my book

the thimbles slip over the tow eye just nice
