Why we stuck in a 4 axle truck!
-The modern buildings in the cities are all going vertical and readymix companies need to big pumps. However the use of these truck mounted big boom pumps have some problems.
-First of all the ROI of high cost of the big boom pumps are not easy as the ones used in projects which can compensate this in the total budget of the construction.
-In the readymix business each pouring operation should deserve the machine on its own. Therefore the amortization period could not be short as 40-30m boom pumps. Because it is obvious that you can not everyday find a job for these big boom pumps.
-There is also operator problem. Because another guy may be the third one should assist him, in any case, to check the pumping units and outriggers while the operator following the boom-end at a close distance. Cleaning is also another issue…
-The operator of big boom pump should be paid more than the other operators using 30-40m pumps. But when you can not find a job for this pump and send the operator with a standard pump what will happen in terms of salary and income justice for pump operators within the company?
-But the main problem for the big pumps used in readymix is another subject. The design limitations*. These machines are considered as truck-mounted equipment and the GVW cannot exceed 32 tons for 4-axle truck on the roads. In some countries highways do not allow five-axle rigid trucks.
-There is a clear need for 5 axle rigid trucks not only for concrete equipment also for municipal and some other vehicles. There are even 6 axle chassis working with special permits supplying safe, economical furthermore functional in the countries where that this truth is seen.
-It is said that this was prevented in Turkey years ago in order to stimulate the use and accordingly sales of truck tractors. It is certain that maneuverability of truck tractor + trailer combination is better. But the need for 5-axle rigid chassis is also obvious.
-To solve this weight problems, manufacturers are constantly looking for lighter but stronger steels. This causes the material to be resistant to longitudinal loads, but to be weak in transverse and breakage.
-On the other hand manufacturers competing in the cheap segment use the lowest level of steel in its class. That means the price difference** which cannot be ignored starts with the boom material from the very beginning. In this point we must say that these pumps visits the workshop more often. And it goes without saying that this shortens the life cycle of the machine.
*This limitation is for on-road and not for off-road trucks.
**Price difference is at least 30-40 pc of the total cost.
