As for the permits, they are there for operators who need them, not for anybody out there. Also a permit does not mean they can legally overload or anything. The permit allows them to go where they normally would not, but would need to in special circumstances. |
Payment of more road tax does not "entitle" anyone to "damage" the road. Just because a person pays more road tax does not mean that person can run amok all over the city with his vehicle. Usage of the road is a privilege that is granted by the government, not a right.
The permits allow them to go where "they are normally
not allowed to go", for example in a crowded business district area at peak hours. Similarly, they are
not allowed in certain residential areas.

Also I have not yet heard of any law in any area that states heavy vehicles are banned from "residential areas". I know many cities implement not to allow heavy vehicles, some within certain time limits, some only on the main roads etc etc. But sometimes you need those big trucks to come along and do their job. Thus the permit system, after paying an extra fee of sorts.

I gave you verifiable real life examples. Even I am not aware of the exact law, but I'm sure the cops wouldn't implement such bans without any legal foundation to back it up, like a section under IPC or CrPC or something like that under which they can "charge" an offender.
Any Indian who has never been to Mumbai in his life will never believe that autorickshaws are not allowed to enter half of the city area. You may very well say that you haven't heard of any law which states that autos are banned from a certain part of the city. For that matter, neither have I. But that doesn't mean it's not true. Any Mumbaikar will tell you that.

As for roads getting damaged, it doesnt take a few hundred trip, it takes more like millions. And a new road properly made local road would have to be abused for months on end for it to be seriously damaged.

Have you ever been to a mining affected area? You greatly under-estimate the destructive power of tippers. I have seen a brand-new state highway get damaged in a matter of days due mining tippers. It's not a pleasant sight.

As for a bridge falling even when one heavy vehicle strays on to it, is obviously not designed to take such loads. But I have not yet seen any such bridge on the roads. The bridges which prevent heavy vehicles from entering will not exactly fall apart the moment one does. But because they are old and have already taken a beating over the years, thus putting it through more beating under heavy vehicles may cause failure at any point of time. You wont find a new bridge which will not allow heavy vehicles, unless they are temporary bridges which cant take that high a load.

There is a narrow bridge over a river, just 500 mts away from my house. It allows access to a crowded old-city residential area with very narrow lanes. No heavy vehicles are allowed on it. And no, it's not older than 15 years.
There are 2 "new" bridges in Pune's prime "Deccan" area classified as 2-wheeler bridges. Again, no 4-wheelers allowed. That includes trucks.
The old bridges you refer to are a different story altogether, most of them were built during the British era. Even they wont fall apart when a heavy vehicle comes in, but you never really know right? Nobody wants to take that risk. Ditto for these new bridges too.
I don't see why its so hard to believe that a residential street is not designed to take the load of tippers.

At this point, I doubt the tipper would be in one piece let alone move.
A 25ton tipper would probably be able to go upto about 40-45tons at best. And that too not on a regular basis, may be once in a while. Even doing it once will cause pretty serious damage to the truck. Like I mentioned before, 30% overloading is the kind you see regularly. At times close to 50-60% is done, but not more than that. So a 3-axle tipper would at best be loaded regularly upto 30-33tons and no more, unless the operator plans to replace his trucks every year. |
My father worked with the Tata Motors CV division for 43 years, the last 10 of which he spent closely interacting with dealers and fleet operators. From all that I have heard from him, I can say that what Pri2 is saying is true, atleast for long distance freight trucks. I won't be surprised if the same practices are used for tippers.
Fleet operators are known to dismantle the complete suspension of the vehicle and add more than twice the number of torsion bars at the back to enable the vehicle to take the load. Even the entire ladder chassis is welded with strengthening bars to prevent it from collapsing. The trucks are then used regularly to haul 3x loads on long distance routes, typically covering more than a thousand kms. And no, they don't fall apart.
But fried clutches are common, and so are bald tyres. Clutch replacement and tyre retreading is the norm after every trip. Because of the money involved, these trucks typically pay themselves back and make a decent profit in an year or so, after which they are replaced with new ones.
The next time you see a freight truck on a highway crawling at 10-15 kmph, its probably because of the reasons mentioned above.
