Transport of a transformer by Bok Seng
At the end of 2021, Bok Seng from Singapore (SG) carried out a heavy and large transport on public roads. A very heavy transformer had to be transported from the port to a construction site.
Here the transport has left the port area and the final checks are carried out before continuing on public roads. The attentive viewer has probably already noticed that the trailer operates very wide. That is correct, as two 12-axle modules are connected in parallel configuration. The width of the trailer is 6.3 metres.
Under escort of the Auxiliary Police, the transport starts moving at approximately 9:45 PM. Due to its width, the transport cannot take tight turns directly and has to manoeuvre several times. Here the transport enters the first busy intersection.
The Scania R 620 is deployed to move the transport. This is the most powerful truck in the fleet of Bok Seng.
Here the transport has moved into the opposite lane, the entrance to the port area. Shortly it will become easier to take the turn. Meanwhile, the auxiliary police keep the intersection closed, and traffic is already becoming quite busy.
Then it drives diagonally forward again...
... followed by reversing diagonally into the adjacent lane. From there, the transport can continue its route and completes the first 90-degree turn in 15 minutes.
Not only the width, weight and length present challenges. The rainy weather also makes it difficult; the Scania adjusts its speed to the conditions.
A two-lane curve is normally easy to take, but not when the trailer is 18 metres long and 6.3 metres wide.
The load is a transformer that is 9.7 metres long and 3.3 metres wide. The weight of the transformer is 181.3 tonnes.
The double 12-axle trailer not only provides better stability but was also necessary to distribute the total weight more effectively. The trailer weighs approximately 75 tonnes, so the Scania is moving around 255 tonnes in this case.
The ballast box mounted above the driven rear axles of the Scania now weighs 25 tonnes. The box itself weighs 5 tonnes, containing two ballast plates from the Kobelco SL6000.
The load capacity per axle line is 45 tonnes, with a dead weight of 3 tonnes per axle line. Theoretically, this trailer could be loaded with 1,008 tonnes of cargo, but only at a maximum speed of 1 km/h.
It is now already 11:15 PM and the transport continues through the industrial area south of Singapore.
The trailer is operated manually.
The next difficult intersection requiring a 90-degree turn has been reached.
Here again, the intersection is crossed...
... followed by reversing diagonally once more.
The construction site is now almost reached; the transport took almost exactly two hours for the route of approximately 22 km. The bridge still ahead of the Scania is the main reason for using the parallel-coupled trailer. Unfortunately, this could not be documented due to a photography restriction. Nevertheless, a very impressive and unique transport carried out by the specialists of Bok Seng!
