Although solar photovoltaic modules have been rigorously tested in the production process, they are still inevitably damaged during transportation, installation and operation, such as cracked or damaged solar panels and the like. Failure to replace them in time will greatly reduce the system efficiency , And even cause system failure.
Current monitoring methods include thermal imaging and (field) excitation luminescence detection, but each has significant application constraints. Thermal imaging can only be used in daylight with an energy density of more than 700 W / m2 Conditions, and field-excited luminescence detection technology can only be used at night under low light conditions.
The Institute of Photovoltaics at the University of Stuttgart, Germany, has partnered with companies to develop a new monitoring technology called DaySy, a new technology that enables real-time monitoring of solar photovoltaic devices by measuring the field excitation luminescence and photoexcitation luminescence intensity of solar photovoltaic modules Of the state of the work in 30 seconds to obtain monitoring results to determine the solar PV modules are intact and can identify common types of failures, such as the fall of the wires between the solar panels, the plate surface cracks, the panel appears photoelectric conversion failure The site, etc., has a wide range of applications.
1. What is the a flatbed Semi Trailer?
Flatbed semi trailer is usually used to transport 20ft or 40ft containers, they are mainly used for container transportation supporting ships, ports, shipping lanes, highways, transit stations, bridges, tunnels, and multimodal transport.
Use platform trailers to transfer cargo at the shipper`s warehouse. Unloaded to the consignee`s warehouse, when changing trailer or boat on the way, there is no need to take the goods out of the box and change them.
The size of the container trailer loading area is determined according to the standard container size.A twist lock device for fixing the container is provided at positions corresponding to the four corners of the bottom of the container. Flatbed trailers are a special trailers for transporting containers.
2. What is the common types of container carrier trailers?
Common flat top semi trailer has four types according to the number of axles, which are the 2 axle 40 foot flatbed semi trailers, 3 axle 40ft flatbed trailers, 4 axles 40 foot flat platform truck trailer, and the single point suspension logistics trailer.
According to the different types of transport containers, there are 4 types, 20ft container carrier trailer, 40 foot shipping container trailer, 45ft commercial flat body trailer, and 20/40ft multi-purpose utility trailer.
we can also offer the 48ft, 53ft and other flatbed trailer sizes.
3. Shipping of container flatbed trailers and marine transportation
When transporting flatbed trailers, many customers use container transportation, which has low transportation costs and short transportation time. But the bad thing is that the rear of the platform semi trailer needs to be composed.
Some customers are bulk carriers or ro-ro ships. CHVM commercial flatbed trailers will spray wax and cover the tarpaulin when the cargo ship is bulking.
4. Flatbed semi trailer buying guide
Container flatbed semi trailers can be produced by all factories. When choosing a supplier, many customers do not understand the differences between container flatbed.
The easiest way is to look at the weight. The heavier the weight of flatbed trailers, the better the quality. The tri axle flatbed trailers purchased by African customers self weighs is 7.1 tons. If the weight is only 6.5 tons, the cost of this trailer can save more than 1,000 dollars.
Here are a few more important points:
1. Working platform of container flatbed semi-trailer
The work platfrom is the main load-bearing part, which is composed of the main beam, side beam, cross beam, bottom floor, suspension and so on. The main beam should pay attention to whether the thickness is an international standard. The international standard for the main beam of a container flat semi trailer is 14/8/16 mm. The steel plate in the middle of the beam is made of Q345B manganese steel, the thickness is 8mm. Many unreliable suppliers will use 6mm main beam to save costs. But the carrying capacity was reduced by 26%.
2. Bottom floor of flatbed container trailer
Bottom Floor, many logistics trailer also can transport bulk cargo and other items. The bottom plate of the Titan high bed trailer passes the international standard 3mm thick checkered plate. If it use 2mm thick pattern plate or a 2.5mm bottom plate. It will cost less $ 700. Tri axle equipment trailer weight limit is 60ton capacity.
3. Axle of flatbed truck trailer
The axles of semi trailers for sale have three types: 13-ton axles, 13-ton axles, and 16-ton brake system axles, 16-ton axles.
The axle of the CHVM container flatbed semi trailers is a 13-ton axle and 16-ton brake system axle, which has better braking performance and shortens the braking distance by more than 5 meters.
4. Tire of flat deck trailer
The 3 axle flatbed trailer uses a vacuum tire with better heat dissipation performance, the model is 12R22.5.
CHVM flatbed container uses custom made tires in a tire factory, wear-resistant tires. On Chinese highways, Titan tires can reach more than 300,000 kilometers.
5. Suspension of container flatbed trailers
CHVM flatbed trailers common mechanical suspension adopts special high strength steel. 6mm thickness. The center pin diameter is 70mm. Stronger than suspensions in many factories.
And we also have bogie suspension and airbag suspension for you to choose.
5. What is the manufacturing process of container flatbed semi-trailer?
1. Engineers provide drawings based on platform semi trailer data and customer requirements and then distributed the drawings to the workers in the production department.
2. According to the drawings of each part produced by the design department, use a CNC cutting machine to cut each part, such as the steel plate for the main beam and the reinforcing plate.
3. Welded container flatbed semi trailers work platform, welded side beams, main beams, welded kingpins, welded suspension, welded bottom floor.
4. Flatbed trailers derusting, frosting, spraying primer, spraying paint, wax spraying; installing axles; installing tires.
5. Print VIN code, waiting for packing.
6. How to load and securing a shipping container on a flatbed?
You can use container tipping tilt chassis trailer, it can load by self.
You can use container side loader trailer.
You can use container lift fork.
