A telescopic air jack quotes a capacity range rather than a single figure, and the two numbers are not alternatives. The higher figure applies on the first stage close to the ground and the lower figure applies once the jack has extended, so the number that matters is capacity at the height actually needed. Reading only the top figure is how a jack ends up rated well below the load at the height it is being used.
That is why a 15 to 30 tonne jack and a 20 to 60 tonne jack are not simply larger and smaller versions of each other. Each covers a band, and a load near the top of one jack's range at full extension may sit comfortably within another's.
Entry height and reach decide whether the jack fits under the vehicle at all. A low entry body slides beneath a loaded commercial chassis that a standard jack cannot get under, and a long reach body puts the ram further in from the edge, which matters where the lifting point is not near the sill. The two are combined on some bodies, which covers a chassis that is both low and awkward to reach under.
Jacking beams work across a pit or a lift rather than from the floor, taking the load on two points with arm extenders and flat roller supports at 2 tonne. Air hydraulic vehicle lifts at 1.5 tonne with foot pedal operation cover lighter work. Questions go over WhatsApp on 07754288583 with the vehicle and the lift height.
