Sideways stability - A truck's resistance to overturning cross. It's crucial to pay attention not only to the center of gravity of the load you are lifting but especially to the combined center of gravity: that of the lift truck and the load it is picking up. Fall. The heavier the load, the further forward the combined CoG will be, to the point where a load heavier than the trucks rating will move the combined CoG forward outside the triangle. How does a forklift maintain its center of gravity? The load is tilted too far back when raised. The sides of the triangle are formed by the center of each front wheel and the center of the rear wheel or at the center of the axle if there are two rear wheels. The stability triangle can be considered more as a pyramid, with the three points A, B and C from Fig 1 joined at the maximum lift height of the truck. the seated inspection, use the three-point technique to climb onto the Driving uphill across an inclined surface moves the combined CG toward the downhill side of the triangle. Since 1992, forklift manufacturers have been required to equip new forklifts with Electric-powered forklifts are most commonly used indoors in warehouses.
