USGS Type A Crane Offset Adapter

Add to Wish List

Click the button below to add the USGS Type A Crane Offset Adapter to your wish list.

This adaptor is used on the Type A Crane with a three-wheel base. It is intended for use on bridges that have an offset (approximately 7 inches) at the bottom of the concrete guardrail. This effect causes the base to lean too far, which makes it unstable and dangerous to use. When installed on a Type-A Crane, this adapter realigns the crane parallel to the guardrail.  This adapter is constructed from aluminum angles, a support rod and attachment hardware (same as power drive mount). The unit easily attaches to the crane.
