This patent describes a method for selectively installing and removing a removable cruciform of a resiliently compressible type, in and from the interior of a generally cylindrical, elongated and vertically oriented ice containment structure, which interior is accessible from an open, upper and thereof. Each such removable cruciform comprises a central housing defining an axis of compression and expansion, means normally biasing the housing in the direction of expansion, legs extending from the housing in a generally radially oriented direction and means on the outer edges of the legs configured to engage a corresponding stiffenning ring rigidly secured on the interior of the cylindrical sidewall of the ice basket, comprising: providing a handling tool having an elongated frame defining an axis, guide means connected to the frame and comprising at least first and second guide fingers extending radially from the axis and angularly displaced thereabout and selectively moveable between retracted and extended positions, and clamping means mounted to the frame and extending axially outwardly therefrom, positioning the tool, with the clamping shoes in the disengaged positions, in axial alignment with and disposed radially outwardly about the central housing of a removable cruciform of the resiliently compressible type; selectively actuating the clamping means to the engaged positions of the clamping shoes for engaging and compressing the central housing of the cruciform and retracting the legs thereof; lowering the tool with the cruciform engaged thereby, axially downwardly through the ice basket to a desired elevation.
