As shown in Figs. 1, 4 a spherical recess 37 in each pad is engaged by a spherical segment 39 adjustably spaced from a bracket 27 by a wedge 45. Compression springs 29, 31 are mounted between the pads 25 and brackets 27 on the ram. The slideways 17 are supported on four corner columns 3, 5, (7, 9) Fig. 2 (not shown), additional slideways (19) being provided on the facing sides of adjacent columns. Means are provided (Fig. 3, not shown) for maintaining the ram level. Fig. 5 (not shown) shows an alternative pivotal mounting.
