Cherry picker forklift won't lift3/17/2024 Now you understand the basics of how a forklift works – just remember, it’s like a seesaw.īut there’s a bit more to the story that you should understand before we talk about calculating forklift capacities and so on.Īnd that means covering the “stability triangle.” What Is the Stability Triangle? The Stability Triangle: Everything You Need to Know If the counterweight is one end of the “seesaw,” then the load-bearing mechanism is the other end. If the counterweight is one seesaw rider, the carriage/forks are the other Technically, it’s called a “carriage,” which is the part connected to the mast and which the attachment – usually a pair of forks – hangs off of. The “load-bearing mechanism” of a forklift is simply the part that handles the load. This is where the load in the front of the truck and the counterweight in the rear strike a balance.Īnd when that balance is maintained, the forklift is stable and won’t tip. The front axle of a forklift is the pivot point or fulcrum So what is the fulcrum point on a forklift?Īnswer: It’s the front axle. If you remember back to science class, a fulcrum is simply the point on which a lever rests and pivots. It does so by providing more downward force than the load on the front of the truck.Īnd this prevents the truck from tipping forward when loaded. Its job is to provide a counterbalance to the load. The forklift counterweight acts as one “rider” on the seesaw CounterweightĪ forklift’s counterweight is a large metal weight located on the truck’s rear. Let’s discuss these components in more detail. To achieve this balancing act, a forklift consists of a: ![]() That is, the weight on one side of the seesaw must be balanced by the weight on the other side.Īnd if there’s too much weight on one side, the lift truck will tip. Understanding forklift capacities first requires understanding how a forklift works.

While you're there, pick up a pint or two of hydraulic jack oil. send an email to Harbor Freight via the website. they'll either have repair parts or tell you where to find them. If you have a Harbor Freight in your neighborhood, go ask the manager for a rebuild kit there's one in every box (which should be telling you something) but i've never used one. you do not want to risk your safety, your car, and your engine to a hydraulic device that can't reliably hold a load. most of us with lo-duty requirements buy cheap tools (like these, and some air tools, and almost anythng made of cast iron) with the understanding that they will be cheaper to replace than repair when the day comes. it'll probably have an O-ring on the head.īut - if yours is leaking at the seals - it may be time to let it go and replace it. To answer your question first - down near the pump area there will be a plug with a flat screwdriver head.
