70 series towing capacity

[Glenn-BJ74]

BC regs

[FONT=Arial, Helvetica, sans-serif]
[/FONT] In BC (mountainous terrain) we are allowed to tow up to 1/2 the net weight of the tow vehicle before brakes are required. So if the net weight on your vehicle registration says 1870 kg (4120 lbs), which is what my BJ74 is, then the towed weight cannot exceed 935 kg (2,100) without brakes.

I can pull 3,500 lbs my BJ74 for short distance in town but the brakes and 13BT are really not up to it. Car makers often say you can tow more, but 1/2 net weight of the pulling vehicle seems very sensible to me for a trailer without brakes

Once the total weight of the trailer exceeds 1400 kg (3100 lbs.) then brakes are required on the trailer no matter what the tow vehicle.

Once the total towed weight exceeds 2800 kg (6160 lbs. then " operator controlled" brakes are required.

If you get in an accident without an overloaded trailer in BC, I believe these regs supercede what the car makers may claim as the safe towing weights.

That is great information to know about BC. Thanks Glen-BJ74. Having individually controlled trailer braking capabilities is a must and the only thing that saved my ass last year when 80km/h winds heading into the pass sent my truck and trailer fishtailing back and forth across two lanes. A heavy application of just trailer brakes straightened things out real fast. No doubt I was overloaded but thought I was OK with my experience as a heavy hauler. Big mistake. This set up was harder to control then anything else I have ever pulled including drilling rigs on 48 wheel trailer combination's grossing up to 100 000KG's. Don't make the mistake of letting your ego dictate what is a safe load capacity.

When I had my BJ74, I thought that it did fairly well for towing...until I put a pyrometer on it. I noticed that the EGT's went up very quickly into the red zone on slight hills, and even though the engine felt like it wanted to put out more, I had to back off on my throttle foot because I didn't want any problems with the engine later.

Makes one wonder how engines that don't have pyrometers fare over the long run, and if the 1250*F pre-turbo that most of us use as the upper limit is a realistic number or if it's too conservative?

Yeah crushers, here in Oz, any trailer over 750kg (trailer + load) MUST have brakes. Once it gets past 3000kg i think it has to have electric brakes. Either way, I use electric brakes on a tandem trailer... i think it's safer.

Yeah, it's slower, but suprisingly enough, once you get a heavily loaded trailer on the back on the cruiser it's as smooth as... like driving in a mercedes. The ball weight must compress the leaves just enough to make them really absorb the damage. Of course it's an absolute ARSE when it's not loaded. I also have a 600kg steel tray on the back of my ute, if you had an alum tray... well, omg.

I'm pretty sure my HZJ75 doesn't have a plate for the GVM upgrade. It was just the suspension and some welding, then you take it to the rego authorities who inspect it and relabel your rego sticker. Probably different in Canada.
