Abstract
A utility line snow or ice removal device mounts to a support structure, such as a utility pole cross-arm. The device includes a moving support arranged to support a utility line, such that a combined weight of the utility line and any snow or ice on the utility line is borne by the moving support. A release arrangement is configured to maintain the moving support in a first position when the combined weight is below a release threshold. When the combined weight exceeds the release threshold, the release arrangement is arranged to release the moving support from the first position to allow the utility line to move under the combined weight from the supported position, creating a sudden movement of the utility line that shakes snow/ice build-up from the line. The device also includes a resetting arrangement configured to return the moving support to the first position when snow/ice has been removed.
