How to compare Jack lifting range without mixing up the numbers

A procurement guide to minimum height, hydraulic travel, screw adjustment and final maximum height.

BUYER SUMMARY

Two Jacks can advertise the same capacity and still fit very different vehicles. Height architecture is often the deciding factor, especially for low-clearance passenger cars, SUVs and commercial vehicles.

01
DECISION POINT

Start with minimum height

Minimum height determines whether the saddle can reach the intended lifting point. Check the final production drawing and vehicle clearance rather than relying on a capacity label.

02
DECISION POINT

Separate travel from maximum height

Hydraulic lift or screw travel is not always the same as maximum height. Compare the complete height stack and note whether an extension screw or alternate saddle is included.

03
DECISION POINT

Confirm the real application

Vehicle class, lifting point, surface, stability and support procedure must be considered together. A Jack raises a load; approved support equipment remains necessary before work begins.

04
DECISION POINT

Freeze the ordered configuration

Put the agreed minimum height, travel, adjustment and maximum height into the quotation, sample record, label and manual so the commercial description remains consistent.

BUYER FAQ

Questions to resolve before approval.

Final suitability, commercial terms and document scope follow the exact model, target market and ordered configuration.

01

Is maximum height the same as hydraulic lift?

Not always. Maximum height may combine the starting height, hydraulic travel and a screw or saddle adjustment. Compare the complete height architecture.

02

Should capacity be selected before height?

Capacity and height must be reviewed together against the target vehicle, lifting point and operating procedure.
