As a responsibleCoupling manufacturer, For the simple packing pin that I sentCouplingThere are two reasons to consider whether to transit the transportation.One: Transit transport goods need to be moved backwards, porters rarely pack goods carelessly and throw them on the ground.Pin couplingThe pin is easy to break, and it is more likely to be like this in winter, and the low temperature will cause the pin itself to be rigid and easy to break.Second:Pin couplingThe axle hole must be vertical for loading. When the freight is placed upside down during the transit, when the truck is running at high speed, there will be a tangential force on the upside down pin. The pin will also be too strong when the truck is running at high speed. Will break, this little bit of common sense is also the company’s experience in many years of delivery. Like everyone tells you, it can help every manufacturer, orCouplingCustomers are the expectations of the company. Honesty is the development of the company, and it is the responsibility of the machinery factory to have a whole-hearted responsibility!
