![]() The LPG or gasoline engine has good emission performance.Fully electric control engine has large power and low energy consumption.Load sensing hydraulic system reduces energy consumption.The truck has fast lifting speed, good sloping ability and high efficiency.Small turning radius makes steering flexible and easy.Semi-suspension seat, small steering wheel, electro-hydraulic direction changing and automobile type double combined switch effectively improve the operation comfort.The operation space is enlarged by heightened overhead guard and using large arc shape of the overhead guard’s front leg.Fully enclosed dashboard and lowering damping device inside the lifting system reduces mast shock and vibration.Cushion connection and whole suspension cab can absorb the vibrations of truck effectively.(Those calculations, by the way, would end up on the data plate, which OSHA also requires be present and legible on all lift trucks, at all times).Technical features remarkably improved, superior quality These are the only entities that can perform the necessary calculations and certify the rated capacity of a forklift. Otherwise, the only way to know for sure how much your lift truck/clamp can lift is by contacting the manufacturer or a qualified third-party (such as a licensed engineering firm). This plate should list the attachment installed and take into account how much less the truck can lift because of it. This information can be found on the data plate, which is usually located on the cowl or near the seat. This brings up the final issue: how can you know how much your lift truck can safely lift? In fact, OSHA standard 1910.178(o)(4) states: “Trucks equipped with attachments shall be operated as partially loaded trucks when not handling a load.” In these cases, attachments can lower the rated capacity of a lift truck - sometimes significantly. So, all handling (to include, but not limited to, lifting, stacking, hauling, etc.) of loads over the rated capacity is prohibited.Ī second issue is what happens to lift truck capacities when an attachment (like a clamp) is installed. I think there are a couple of different issues in your question that we can try to tease out and answer…įirst, I detect some version of the question: Can I handle a load that weighs more than my lift truck is rated for, even if I’m not going to be lifting it?Īnd the answer is “no.” OSHA standard 1910.178(o)(2) states: “Only loads within the rated capacity of the truck shall be handled.” This standard doesn’t provide any exceptions. I know it’s more complex, but I belive the formula even in OSHA field calculation may only pertain to a fixed mast forklift, not a telscopic rough terrain forklift like we typically use in construction. ![]() So, for instance, your boomed out and up and the load chart says in that range your good for 6,000, you would reduce that by 3,700lbs, and only allow for a maximum lift weight of 2,300 lbs. When reading the load chart on a rough terrain forklift, you need to reduce what the chart is telling you it’s rated for by 3,637 pounds ( I typically just round it up to 3,700 lbs to make math easier… When you end up with a load with a center of gravity at 48″, you calculate the new ACTUAL OPERATING CAPACITY by using this equation: ![]() The equation is A (DISTANCE FROM CENTER OF FRONT AXLE ON A FIXED MAST FORKLIFT TO THE FACE OF THE FORKS – this number is NEVER changed)Īctual equation is: (A+B)XC= inch pound capacity forklift is rated forįor a 10,000 capacity forklift – (18+24)X10,000 = 420,000 inch pound capacity Has anybody ever used the inch pound equation to determine the forklift capacity with loads outside the rated center of gravity of 24″?
