jacks with lifting capacities from 20.3 tonnes (20 tons) to 203 tonnes (200 tons) have been introduced by Spencer Franklin.
They are between 280 mm (II in) and 300mm (11,8in) high, and the smallest in the range includes a screw extension which permits an additional 100mm (4in) adjustment to the total lifting height of 170mm (6.7 in). The 10I-tonne (100-ton) capacity jack incorporates a secondary low-pressure pump to give a rapid lift up to 15.2 tonnes (15 tons).
