The ground plate components are welded together. The plate (3) has a hole to accommodate a threaded spindle (6) through an hole in an upper support plate (5) and secured by a nut (14). The spindle is welded to the nut and upper support plate. The spindle is further secured through the top of the ground plate where it is secured by two nuts and washers (8, 9, 7a, 7b) with vertical adjustment.
