Load Capacity
Lift and dump capacities of hydraulic hooklift hoists typically range from 8,000 to 68,000 lb (3,630 to 30,800 kg). Generally a hoist is capable of lifting (off the ground) and dumping (onto the ground) the same maximum capacity, although there can be exceptions where short wheel bases are involved.
The ratio of container length to chassis length is a factor in achieving rated load capacity. This ratio determines the load angle, and all hooklift hoist systems indicate a recommended range of body lengths, typically 3–5 ft (914–1,524 mm) difference in length between the container and the chassis. Container bodies shorter than the recommended length produce substantially steeper load angles, and consequently lower load rating, than those of the longest bodies intended for use with a particular hoist.
Chassis frame height is also important, as the lower the chassis frame height, the lower the potential load angle. A combination of low chassis with the longest recommended body lengths offers the best case.
Finally, hook height has an effect, as a taller hook height achieves a greater lift and dump capacity.

Famous quotes containing the words load and/or capacity:
“Tobacco and opium have broad backs, and will cheerfully carry the load of armies, if you choose to make them pay high for such joy as they give and such harm as they do.”
—Ralph Waldo Emerson (1803–1882)
“A creative writer must study carefully the works of his rivals, including the Almighty. He must possess the inborn capacity not only of recombining but of re-creating the given world. In order to do this adequately, avoiding duplication of labor, the artist should know the given world.”
—Vladimir Nabokov (1899–1977)
