Covid has repercussions everywhere. The delays for delivery of new trucks and trailers are very long these days. It can take from 8 to 12 months right now to take delivery of a new piece of equipment.
Since the beginning of the pandemic, the negative effects on the supply chain have been multiplying and now touch all aspects of vehicle production. Reduced labor , reduced supply capacities of base materials such as steel and aluminum, tires, mechanical parts and now semiconductors have really complicated production and can even result in the complete shutdown of production for certain types of vehicles.
Manufacturers have the production capabilities, which is not the problem. Even if they had to stop production for a certain time because of the pandemic and even though in certain situations they can even add second shifts to increase production capacity, they simply do not have the materials or components necessary to produce complete vehicles. For certain types of equipment, they produce nonetheless, park them outside and wait until the missing parts come in to finish assembly. It is a huge puzzle and a major problem this year.
