How to maintain the “2axle lowbed semi trailer”?

2axle lowbed semi trailer transporter, also known as construction machinery transporter, is mainly used to transport some non-removable objects like excavators, loaders, and harvesters.

The loaded goods are from 3 tons to 30 tons, suitable for long-distance transportation of construction machinery and some non-removable goods. The modified part adopts plate thickness: 5mm checker plate, climbing ladder: 120mm set of 100mm channel steel, beam: 100mm national standard square steel, flat plate The ground height is 850mm-900mm. The cargo platform is 6 meters long and 2.5 meters wide. It is the most ideal model for transporting 8-12 tons of small excavators, bulldozers and harvesters. The cargo platform is only 0.85 meters above the ground, which is suitable for transportation in various road conditions.

In addition to the whole vehicle, there are also 2axle lowbed semi trailer transport vehicles, also known as semi-trailer construction machinery transport vehicles, which usually use a concave beam (or well-type) frame. It is connected to the traction saddle on the tractor, the rear end of the gooseneck is connected to the 2axle lowbed semi trailer frame), the middle section is the cargo platform (the lowest part of the frame), and the rear end is the wheel frame (including wheels). When loading machinery and equipment on the semi-trailer construction machinery transporter, the machinery and equipment are usually loaded from the rear end of the 2axle lowbed semi trailer, that is, the machinery and equipment are moved from the rear wheel frame or the wheels are removed, and then the machinery and equipment are fixed on the on a 2axle lowbed semi trailer.

Maintenance 2axle lowbed semi trailer should pay attention to the following points:

  1. The connection between the supercharger of the 2axle lowbed semi trailer and the intake and exhaust pipes must be tight and cannot leak air. If 2axle lowbed semi trailer is air leakage between the exhaust pipe and the exhaust gas turbine, the efficiency of the supercharger will be greatly reduced, and the exhaust temperature of the diesel engine will rise sharply and be damaged. Valves and superchargers.
  2. Before starting the new engine, the supercharger and supercharger oil filter must be filled with clean oil to ensure that the diesel engine starts together and the supercharger bearings can be lubricated. After the car travels 8,000 to 10,000 km, the oil filter element of the supercharger must be replaced.
  3. Before the diesel engine stops, the 2axle lowbed semi trailer should run for 3 to 5 minutes at idle speed, so that the speed of the supercharger is lowered, the temperature is lowered, and the running sound of the supercharger is monitored. If any abnormality is found, 2axle lowbed semi trailer should be stopped for inspection. If the rotor of the turbocharger is inflexible, there is sticking or wear noise, it must be sent to a qualified repair station for repair.
  4. For the 2axle lowbed semi trailer, after every 500h or 30,000km of operation, the clearance on the supercharger rotor shaft should be checked, and the dust and carbon deposits on the compressor turbine casing and rotor blades should be removed. At this point, the turbocharger should be removed from the diesel engine and the metal gasket between the exhaust pipes of the supercharger should be replaced. It is not allowed to use mechanical methods to remove the scale on the rotor parts, but use gasoline or other cleaning solutions for cleaning aluminum parts.
  5. The lock nut of the turbocharger compressor cannot be disassembled, other wise the dynamic balance of the turbocharger rotor will be destroyed and the turbocharger will be damaged.
  6. Do not damage or deform the rotating parts of any removed turbocharger, otherwise it will affect the balance of the 2axle lowbed semi trailer. Likewise, any rubber seals must not be damaged.

After doing the above points, you can go on the road safely. Finally, I wish drivers and friends a safe journey!
