Abstract
A tower is hinged to a base, positioned at one side of a well, so the tower can be lowered to the ground in a direction away from the well. A lateral platform at the top of the tower extends over the well and the tower is rotatable, about a vertical axis, to swing the platform laterally and clear of the space over the well.
