Supro`s Quality Control System - Learn about how do we produce hydraulic modular trailer for you.

❐Why does Supro Trailer has so many loyal customer fans? So we have a high repeat order rate! In the following video, we will introduce how our company ensures quality control during the production process, and you will also learn how to distinguish good supplier from ordinary product suppliers.
❐The strength and quality of the frame are primarily determined by the welding process. Firstly, let me introduce our welding technology for you! Supro Trailer requires our production workers to strictly follow the welding technical requirements and never allow anyone to reduce the workflow to save their working hours! For example, when we use Q690 steel to produce Supro THP/SL, the workshop workers must preheat the steel before welding and make heat insolation of welding lines after welding. So it can guarantee the welded frame do not be cracked in future! However, this is still not good enough for our quality control system! Therefore, for some well-welded steel structures, Supro Trailer also uses some fixtures to fix the steel structure to prevent deformation due to welding. After we finished whole structure welding works, Supro Trailer continues to polish the surface welding lines to make the overall surface be smooth as a mirror and make the appearance of the hydraulic modular trailer as an industrial artwork! When we are welding different thicknesses of steel beams, for example, the main beam of the hydraulic modular trailer has different thickness of combination head. Our welding technology can make it looks like a casting structure! Even you can not distinguish it is welded or casting! This can maximize to guarantee the structural strength of hydraulic modular trailer and extend the service life of it!
❐As we all know that when we are going to combine a drop deck bed of hydraulic modular trailer or assemble a bridge structure transporter, the most important part is the various combination files which do not allow any dimension error! Or the combination bolt can not go though those files. Our company has a large grinding equipment to ensure the perfect combination between the bolt and files! This equipment is also used to ensure that the bolt holes surfaces at both ends of the hydraulic modular trailer are in the same longitudinal plane, so that the cross-section between the two units of hydraulic modular trailer is more evenly stressed.
❐Next, Let`s talk about how does Supro Trailer ensures that each hydraulic accessory which we are using is qualified! Firstly, we require our hydraulic cylinder suppliers have to make pressure charge testing on every hydraulic cylinder before delivery. So it can guarantee that we are using qualified cylinders on our hydraulic modular trailer! Even for some small hydraulic accessories which are numerous in quantity such as quick connector, hydraulic valves etc, our company also randomly take 30%-50% of them to make pressure charge testing at our workshops. Supro Trailer has professional machine to make the testing. As long as we found 1pcs of accessories is unqualified, we will make testing on each hydraulic accessory! So that it can guarantee stablity of our hydraulic modular trailer in future!
❐Supro Trailer requires that all hydraulic and electrical system layouts must be clean and tidy! It can make you free easy and help you save lots of time and energy on future maintanance and repair, ! Also we think it is a basic demand of a superior quality of hydraulic modular trailer!
❐Before laying out the hydraulic pipelines, we use automatic equipment to bend our hydraulic pipes, which increases the accuracy of the bend angle. If pipes are bent manually, they may break easily during future using. But our hydraulic pipelines never has this accident! After we cutting the hoses, we also use specialized equipment to wash them and remove impurities. This ensures that there are no impurities in the hydraulic system which could affect the stability of the hydraulic modular trailer in the future. Finally, when we make combination between hoses and quick connectors, we also use specialized equipment to do the job to ensure that the combination will never come off in the future.
❐Of course, we believe that a strict product quality control system should also be reflected in the appearance of the trailer. So the company would never allow their vehicles to have an unappealing appearance. Supro Trailer would make twice polishing works on the surface of the hydraulic modular trailer and make the last painting surface bright as a mirror! Therefore, we inspect the entire vehicle's exterior, including hydraulic suspension by our suppliers, to check for any production residue or marks. If it has, we will clean and repair them accordingly.
