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:
“Rich are the sea-gods:Mwho gives gifts but they?
They grope the sea for pearls, but more than pearls:
They pluck Force thence, and give it to the wise.
Every wave is wealth to Daedalus,
Wealth to the cunning artist who can work
This matchless strength. Where shall he find, O waves!
A load your Atlas shoulders cannot lift?”
—Ralph Waldo Emerson (1803–1882)
“There is only one honest impulse at the bottom of Puritanism, and that is the impulse to punish the man with a superior capacity for happiness—to bring him down to the miserable level of “good” men i.e., of stupid, cowardly and chronically unhappy men.”
—H.L. (Henry Lewis)
