Interested in buying a used forklift? You'll need to take a number of factors into account when you're making that decision. It's just like buying a used car - you need to know both about the model that you're looking at and the specific stuff about the particular forklift you're considering buying - is it damaged, how much wear and tear has been put on it, etc. Because this is usually for industrial use, you'll have to think about some other stuff to make a cost-benefit analysis as well.
First, if you're buying a used forklift, you need to inspect it. If you're not an expert on forklifts (most people don't have specific knowledge about them in they way they would if they were buying a car), you should look into a couple of things. First, go to the manufacturer's web site. You can usually find some specific details there about all their models. You'll want to make sure that you know what it originally cost, and you should do some poking around to see if you can find recent used sales as well.
After that, you can actually find a lot of used forklifts online pretty easily. Just check out e-bay:
Second, test it out once you find one you want to buy. This is the most important part - you need to make sure that it can still lift the weight limits that you're going to be using it for. Drive it around yourself if you're certified and know what you're doing - they should have something around the yard that you can pick up with it, and if not, then bring something with you or ask to take it out to your site. It's a big purchasing decision, and you want to get it right.
Third, you should compare fuel efficiency on the older model with what newer ones are getting. This can be a big cost sink - you need to assume that you'll have to pay out a little more on repairs every year, and with older, used forklift models you'll probably have to buy more gas. That can add up to much higher expenses to operate it than with a new, more fuel efficient brand. So make sure that you're getting a good deal - if you're wasting tons of money to keep it maintained, then it might not be worth it to get a used one. On the other hand, if it's much cheaper than a new one, then just pay the fuel costs.
