Last week I asked a manager from Heli head office the same question. He told me that Heli is the only Chinese forklift manufacturer that makes all their own components or imports top quality ones. They can therefore assure quality. All other Chinese companies buy nearly all their parts and assemble. They have less control over quality of materials. That is why they can have lower prices.
Take it or leave it.
I am a marketing consultant to three distributers, one of them a Heli dealer, and they say that they are more than satisfied with the quality of the Heli trucks.
