Does this apply to trailers also?

Procedure for Registration of new vehicle

The page reads "Bonafide agriculture certificate issued by the Tahasildar in case of registration of Tractor-Trailor unit used for agriculture. In case of new trailor, design approval proceedings issued by Commissioner for Transport to be produced."

so if I build a trailer I need design Approval by the CoT - now who is this and what the right way to do it?

(mod's kindly merge this with previous post)

Well actually reversing is a big pain especially in jeeps. Tractors with trailers tend to behave and moves in the direction you want it to but the jeep trailiers really need you to practise.

@dirtydan
What does this term refer "Drive Terrain Windup"
Is this harmful for the engine. I remember reading somewhere that if this happens then the 4x4 does not work. How does one know that this has happened! And what is the wauy to rectify this???

think for a Jeep - it would be better to tow it right away like this

I have already got the ball and cup for the trailer.

Corbett is just an example!!!

Actually, you can. But you need to get it fabricated with a registered trailer manufacturers. Many of the tractor trailer manufacturers will know the process, however the tonnage that they are permitted needs to be cross checked.

Yes, this is the same trailer I got.

I have seen army CJ3Bs getting dispatched from Kandivli plant with these trailers attached.

I have driven Jeeps fitted with the trailer. For towing the trailer, pintle hook and "K" member on the chassis are a must otherwise the chassis will get damaged. For vehicles with back mounted fuel tank, a reinforcing member is added behind the chassis to provide section modulus equivalent to the "K" member. Reversing is a big pain and requires special skills to negotiate otherwise the trailer will just about go anywhere.

Best regards,

I was thinking these trailers were made by (collaboration?) with Dunlop, is it not ?

[Irfanulla]

Thank you Trammway - I will chk the manufacturers building the tractor trailers -

Think Satrac is one such builder - does anyone know - anybody else operating at a much smaller scale?

Folks, finally I collected my Trailer out from the scrap vendor along with new registration papers.

It is a real new experience with my jeep, found myself in trouble few times while driving through the heavy traffic roads, as i took the trailer in around 4:30pm today and tow it straight to my sand blasting workshop. It was around 30kms drive and couple of places I really had big time in trying to reverse the trailer with no big success. Finally had to remove it from the jeep and manually reverse etc.

while taking the trailer delivery, I saw a 1ton trailer up for sale with the vendor. I think it is too big for a jeep. In the 1 ton trailer, I also noticed the power plug used for tail light setup. You know what, not the plug setup is in my custody. Hope to fix them in my trailer soon. Here are the pictures:

Here are some pics illustrating the uses of the Jeep Trailer 1/4 ton capacity. Can be loaded upto 1.25tons

Reversing the mahindra oven trailer is easy provided the trailer brake is disengaged by placing the U between the hook and the yoke..

Tramway as seen in the pic the clamp is in place and the trailer brakes are disengaged so U must not have a problem of brakes holding when backing up.

Imagine you are manually pushing the trailer back, keeping in mind this principle the jeep also has to be steered i.e., to reverse the trailer left the steering has to initially be turned almost right end and as you move back return to almost left end. to reverse right its vice versa. A little bit of practise will get you the skill.

It was mahindra oven manufacturing the trailer when my grand father bought the trailer in 1978 it costed Rs.6000/- for a brand new one.

I did notice the U clamp which is attached to a chain and I guessed it right. However I removed it when I was driving forward as I heard lots of noise as every time I applied break in the jeep. But I really forgot to engage the U clamp while reversing. It's a good tip, however I did notice another issue when I could do the reverse I manage to reverse the trailer at the desired direction but after that the one edge of the trailer hits the rear bumper of my jeep, not sure how to handle it.

my next question is regarding the angle in which the trailer is fixed. I could see your MM540 and Trailer combination is on a straight line. But looking at my 15 inch Mahindra Classic wheels with 16 inch Jeep wheels on the trailer

[Timson]

Ya getting back to your query.

1. The noises you heard when you applied breaks are probably from the trailer brake drums, liners must be hard/rough and the drums might also require polishing. Ask your service chap to redo the brakes and adjust it properly. Fix the U-clamp drive and check if you still hear the noise when you brake, if you don’t then it’s the brake drums.

2. When you start reversing try not to get the jeep locked in a V position with respect to the trailer, as the trailer moves to the required direction be quick to turn the steering to the same direction, wish I could give you a demo. To experiment better put the jeep transmission in low and try backing up so you will have time to react and steer accordingly.

3. For the Jeep and Trailer combination to be in a straight line. In your case I suggest to reduce the arch of the trailer spring set(i.e., the rear of the trailer will sink) and increase the arch of your CL-340 rear spring set(i.e., the rear of the jeep will rise) hence levelling the combination to a straight line. The 16” tyre of the trailer and 15” tyre of your CL-340 wont make much difference to the inclination.

Have a great time towing..

@Timson
Do long downhill drives cook trailer brakes? I suppose there should be mild pressure on the brakes if the slope is steep enough.

[Brutus]

The mm540 trailer has some load on it. When you load your trailer it too would be level. If you try getting it level with the jeep when its empty(by re-aching), then you better watch out for the mudguards rubbing with the tires whenever you would load it. My cousin did just that, and now if he has like 20 sacks of field produce in his trailer, he's already rubbing the mudguards, whereas mine still works perfectly.

[Parm]

i think the towed trailers in india should have adequate tail lights and rear reflectors for safety reasons, which i think are missing on most of them in the photos posted.

from day 1, i have never seen any tractor-trolley combo on indian roads with tail-light for the trolley behind the tractor, and no one is bothered about enforcing it!

Excellent inputs, I will sure try them in a week after the trailer body work gettting finished. Break drum idea also interesting.

I was exactly meaning the V locked position. I have found myself having the trailer edges and jeep's bumper edges are kissing. As you said the practice works better, I will try them hard after getting the trailer back at my hands.

Do you have any pics to illustrate ?

I have observed it too, the problem is that availability of proper equipment. See in my previuos posts, I was talking about the plug point from 1 ton trailer to my trailer however I still needs to find the plug itself.

I have a question for Army men here, why did the Army trailers (1/4 ton) didn't come with rear door ? I could see Chengappa's (Timson) trailer got a rear door. Not sure if the Army supply and what Chengappa owns are same makes because the hook setup, rear door and body support frames on the side walls are all different.

[Timson]

Trailer back door..
Ya the trailer with the MM-540 is not a army supply nor its an mahindra product, it was custom built by a trailer building company by name Kaveri Trailer works at kushalnagar, kodagu.
The reason for not providing the door for the army trailers is that it had to be water tight for carrying ammunition and other stuff. You will notice that there are no water drain holes on the bottom bed too if water filled in the tub. The door was eliminated also to provide collective strength to the side walls as it’s made of thin pressed sheet metal.. In my trailer the sides are made of 12gauge folded sheets and also reinforced at the ends. See the pic attached below a trailer with army men crossing a river, the jeep here is a Ford GPA.

Long downhill drives..
It will not cook the trailer brakes provided the brakes are adjusted properly. Trailer brakes give a good assistance to the jeep brakes down hill or wen applying brakes. Ya a mild/sufficient pressure on the trailer brakes is required.

tail lights and rear reflectors..
You can see reflectors fixed on my trailer. I agree with (trammway) that’s ‘the problem is that availability of proper equipment’ It’s been a long time hunting for a proper setup, as quoted before only the female connector end is available. TAFE tractors are being provided with the trailer light wiring provision. But I haven’t been able to procure the setup. Also a capital T has to be painted on the rear to inform the driver behind.. In one of the pics posted by trammway, a reflector T can be seen on the tool box of the army trailer.
