Abstract
1329830 Offshore platforms with rack and pinion jacks ARMCO STEEL CORP 13 Nov 1970 [14 Nov 1969] 54138/70 Heading B8J Legs 2 of an offshore platform 1 each comprise three columns 5 interconnected by braces 6, 7 and are raised and lowered by rack and pinion jacks 20. Each column 5 has a dual rack 11 (i.e. a rack with two opposed sets of teeth 12, 13) and to avoid disengagement from the drive pinions 41 the latter are arranged in pairs as shown in Fig. 5. Each pinion 41 is driven by its own electric motor 47 via a speed reducing gear-box 47. The flat faces 14 of the racks 11 engage respective guides 62.
