Outer Limits 4x4 Board

Do we think a 79 series turbo diesel ute will be able to pull a 6 tonne boat and trailer in and out of a boat ramp in low range? Or will it end up in a watery grave? 2tonne car pulling 6 tonne boat up a wet ramp...Is it possible?

Are they R or H series g/boxes?

4wd, Low range, second/first would be your answer there... Landcruisers are only graded to tow up to aproximately 4 tonnes think it was.

Could also result in lots of wheel spin and slide down hill

legally tow capacity is 3.5 tonne on cruisers. But boat won't be towed on road by landcruiser. It will be towed on road once prior to fit out when it should be approx 3.8T. Once its fitted out it will sit on hardstand at a club and will only need to be dragged in and out of ramp.

as a surgestion take it offroad or somthing get a steep hill n see what happens just as a slight insight to if you got enough power ofcourse you dont have to water and slip n slide but just an idea..

depends if it can get traction.

if its a slimy boat ramp then it will probably become a submarine.

if its a nice rough concrete and the boat ramp isnt too steep it should do it easy.

Id be worried about the drivetrain though.

6 tonne is alot of weight, and in low range thats a crapload of force

Thats a point... if the boat ramps slippery your a boat.

How about get a second cruiser in front of u off the ramp with a cable attached to take the load if u lose traction? or a "tree trunk winch" or... a Truck hehe lol

I've seen F trucks tow 5 - 6 tonne gooseneck horse floats threw mud. They did it now worries but they did slip and slide around lots.

I think it will be fine in low range and tyres aired down.

Just make certain your insured and its up to date first hehe

excelent point tires down

i dont see why it would be a problem in low range
if it slips back down the ramp it shouldnt go too far... rememeber when the boat hits the water it will become bouyant and float thus having less "pull" on the cruiser down the ramp.
if your really worried id just tie a strap to a second vehicle just in case....
preferably not an excell or any other tin can

Unless the boat is still tied down

Yer your exactly right. The worry is not so much the car slipping back, but rather just will it have the balls to pull it out without doing a g/box etc. The ramp is actually well used so isn't too slimy and compared to other ramps actually isnt as steep.

Just got to try and make the right decision at the start, i.e. cruiser ute which has more every day advantages for getting around and doing other 4wding and camping trips, or pickup a small older 4wd truck i.e. canter etc purely for launching and retrieving the boat.

Boat should have enough buoyancy to float even with the trailer strapped to it lol.

Was an incident at a local ramp recently where some blokes trailer popped off the hitch whilst he was launching. Jumped out to chek what was going on without putting on the handbrake or parking in gear etc, and he ended up loosing the whole lot down the ramp. hahaha

Turbo Diesel, Non turbo diesel or petrol model...? if its a turbo diesel or petrol then you will have the h151f gearbox, no strength issues... even the R series box should be ok in 1st and 2nd as they are well supported on the shafts they run on....

6 Tonne is heavy.... especially from a standing start, on a slippery incline...

Low range, tyre pressure dropped, and another car acting as a safety, and a good supply of clutch plates...

If its not going very far, as you have said, why not extend the drawbar on the trailer. It will get the 4wd onto the flat section sooner, and less chance of getting saltwater near the vehicle.

Ability will only be limited by the available traction.

Trailer is being built with an extendable draw bar...but it is also being built relatively low due to the height of the boat on the trailer. So we're not exactly sure yet if it will bottom out (ramp over) on the ramp whilst the trailer is on the ramp and the car is on the flat.

First launch is going to be soo much fun...could be two very red faces lol.

it will do it easy, heaps of prfessional fisho's use cruiser utes to put 8 or 9 meter boats in and out of the water all the time. but do it at high tide as there is less sand and slime at the top of the ramp. also heaps of revs is not the answer, slow and steady take off is the key.

iv launched and retreaved a 5 ton boat with a 80 series and had no issues.

another point... if you stop and get out to put boat on trailer might be a point to leave the car in first for a bit of extra "braking power" seen as how your not acturaly graded to anywhere near that much. Cause it could put a fair bit of stress on handbrake...

I got a 60 series petrol and tow a 27 foot Regal in and out of the water all the time. bout 5t worth
I just use low range 1st lock both my diffs and virtually idle out, bout 1000-1200 rpm

No issues with the cruiser copeing with the load, but you have all looked past what is clearly hitting you in the face.

Cruiser (RATED) towing capacity = 3.5t
Cruiser + 5-6t boat (cruiser is overloaded) = Insurance will not pay in the event something does happen as you have blattenly gone over the maximum legal rated towing weight of that vehicle.

And we all know with our own life experiences that the insurance company does not want to pay it will find a loophole for sure.

Ben

Good point, wow this got pulled from the depths

very true...however as I said above though the cruiser would only be used to launch and retrieve the boat at the ramp, so no onroad work as the boat will be parked on hardstand next to ramp. So the only time insurance would be needed is if the whole lot ended up in the drink which as you stated, they're most probably not going to be interested in.

Get a 9 tonne electric or manual winch and tie it to a tree (preferrably a strong tree) Use that If you spin wheels

I dont think the 'full of their own importance - dressed in whites, brass and top hats' yachties at the yacht club would appreciate that. Not even allowed to drive the boat on the trailer, let alone winch off of their trees.

Certainly is...not one of the board members, or the 'Commodore' etc etc are you? lol

Nah man i do some work there and put boats in and out fairly regularly.
lol

LOL ok I hadnt thought about that

The way i see it is that even though the boat may weigh 6t doesnt mean that the towing vehicle in question will "directly" be pulling 6t as the load is technically lightened by the quantity of trailer tyres involved - bit like a pulley system.

It would be more realistic to be pulling 6t "realistically" if you had to skull drag it out without the trailer as it would be a dead load

Its like me sitting my cruiser on the flat and pushing it along with 1 hand- doesnt mean im real strong and can push 2.5t single handedly just means that the load resistance is is much less while it has tyres under it.

bit off topic but thats one of the reasons why engineers are concerned about increased tyre width. this is because the facory tyres are designed to take a certian amount of point load per corner. by fitting wider tyres you technically lighted the vehicles downward pressure as the load is now distributed over a larger surface area.

Back on topic - you will be sweet with your boat launch regarding the weight.

um, wtf....

A vehicles rated towing capacity is based on a rolling load, not 3tonne of metal sitting on bitumen.

Its 6 tonne of weight, its double the rated towing capacity of the vehicle.


And as for your point about tyres, just wtf.

seen a place up here that has a tractor for doing this don't know what it cost to get launched or retived but it's not a big tractor and they launch some decent size stuff. might be something for the club to look at.
