open utility trailers, also known as the construction machinery transport vehicles, mainly used for transporting some like excavators, loaders, harvesters like the non-removable objects.
The goods loaded in the 3 tons to 30 tons for construction machinery and some non-removable goods long-distance transport of its modified part of the use of plate thickness: 5mm pattern plate, ladder: 120mm sets of 100mm channel, beam: 100mm GB square steel, Ground height 850mm-900mm. Cargo length of 6 meters, 2.5 meters wide, is the transport of 8-12 tons of small excavators, bulldozers, harvesters the most ideal models. Cargo from the ground only 0.85 meters. Suitable for all kinds of traffic
In addition to the vehicle, there are semi-linked open utility trailers, also known as semi-hanging engineering machinery transport vehicles are usually concave beam (or well) frame, both front of the front of the car for the gooseneck (gooseneck traction pin And traction saddle on the tractor connected to the back of the gooseneck and semi-trailer frame connected), the middle for the goods (the lowest part of the frame), the rear wheel frame (including wheels). When loading mechanical equipment on a semi-trailer mechanical vehicle, it is usually loaded from the rear end of a semi-trailer, that is, by moving the mechanical equipment from the rear frame or removing the wheel, and then fixing the machine Semi-trailer.
open utility trailers transport care should pay attention to what:
1, open utility trailers turbocharger and the inlet and exhaust pipe connection must be tightly not leak, if the exhaust pipe and exhaust gas between the gas, the efficiency of the supercharger will be greatly reduced, the diesel engine exhaust temperature will rise sharply And damage the valve and supercharger.
2, the new machine before the start of the supercharger and supercharger oil filter must be filled with cleaning oil to ensure that the diesel engine to start, the supercharger bearing that can be lubricated. Car driving 8000 ~ 10000km, the need to replace the supercharger oil filter filter.
3, open utility trailers in the diesel engine before the shutdown, should be idle in the operating conditions for 3 ~ 5min, so that the supercharger speed down, the temperature decreases, and monitor the supercharger running sound. If abnormal, should be detected. Such as supercharger rotor rotation is not flexible stuck or wear sound, to be sent to repair the condition of the repair station.
4, open utility trailers, every 500h or 30000km, should check the supercharger rotor shaft clearance, and remove the compressor turbine shell and rotor blades on the dust and carbon. At this point the turbocharger should be removed from the diesel engine, replace the supercharger between the exhaust pipe metal gasket. It is not permissible to use a mechanical method to remove fouling from the rotor parts, but to use gasoline or other cleaning solutions for aluminum parts.
5, open utility trailers turbocharger lock nut can not be disassembled, otherwise it will destroy the turbocharger rotor dynamic balance, causing turbocharger damage.
6, do not make any removed turbocharger rotating parts damaged or stressed, otherwise it will affect the balance of the open utility trailers turbo. Also can not damage any rubber seal.
