![]() If your not sure about any of this hire a professional tech to troubleshoot it and repair it. Not to mention the forks will be comming down quickly too! By all means DO NOT loosen the pressure line while it is up in the air, that is very dangerous and will get you wet with oil in the process. Now when i say return line i DO NOT mean the line going from the control valve to the cylinder, i mean the big hose going from the control valve back to the tank. If you get more than a trickle then you may have a bad control valve or check valve issue. You may get a slight bit but it shouldnt be alot. There is one test you can do, when you have it raised up pull the return line off and see if there is any drainback. ![]() If when you raise it all the way up and leave it for a while see if it bleeds down then, when raising it up to the top it might be putting enough pressure on the cylinder to hold it there temporarily? or just applying enough pressure on the packing to expand it and then it holds. But if it is still falling down while you have that lever pulled it sounds like an internal cylinder issue. The thing about it slowing down when you pull the lift lever is only that it is applying pressure to the cylinder trying to raise it back up. My best guess is you have some packing issues in the cylinder allowing the rod packing to bypass. My guess is since it is what you say a "single cylinder" that it is a multistage telescopic cylinder? or is this just a simplex mast freelift (does not go up very high) Understanding these basics is a critical part of finding the perfect forklift.If its dropping 10ft in 10 seconds you have a serious issue Many forklifts without free lift are used for outside applications where clearance and racking are not a concern.Ī forklift’s mast is one of its most important parts. This often times creates clearance issues. To raise any load, the entire stage has to lift. ![]() Without free lift, a load is always at the bottom of the first stage. Free lift effectively adds a stage level of height to a forklift’s ability to lift and uses a hydraulic cylinder at the center of the mast. Without free lift, the entire stage has to move up together while the forks and load stay at the bottom of the first stage. Free Liftįree Lift is a forklift’s ability to raise a load to the top of the first stage. A 3 stage is the most common type of forklift we sell, which means the mast almost triples in height. Stages are rails that fit inside each other, so if 2 stages are extended, the mast nearly doubles in size. StagesĪ stage is a section of the forklift mast. They’re the least popular of the 4, but a perfect fit for some uses. They’re for applications that don’t require much height and aren’t limited by clearance. V Forklift Masts are 2 Stage Masts without Free Lift. I think if 5 Dans stood on each other’s shoulders, they might come close! ![]() ![]() They have 4 Stages with Free Lift.ĭan, our Vice President of Sales and Marketing was nice enough to model with one to better show it’s height. When you need to lift very high, you go with a QFV. They’re second most popular behind FSV for applications that don’t need quite as much height. 131.5” Maximum Fork Height is the most popular size.Īn FV Mast is 2 Stages with Free Lift. It’s the most popular type of mast we sell. Toyota FSV Masts are 3 Stage Masts with Free Lift. (Afterwards, we explain Stages and Free Lift.) FSV Forklift Mast – 3 Stage It’s also important that your forklift fits where it needs to and has proper clearance. Selecting the right forklift mast is important to raise materials to the ideal height. What are FSV forklift masts and FV forklift masts? We’ll Explain V and QFV Masts As Well ![]()
