BAIRSTOW LIFTING CHAIN CONTAINERS (BAGS) Bairstow Lifting Chain Containers (bags) are designed to assist with the containment of excess lifting chain resulting from loads being hoisted, thus preventing common hazards associated with loose chain. Our patent pending design is unique because it allows for the field installation of the bag with no special tools, on every type, brand, and style of hand operated and some electric chain hoists. We have designed our bags with the utmost attention to safety, convenience, and strength. Each bag carries a 500 lb. rating which is more than enough capacity to satisfy almost any lift chain requirement. Please see the visual installation guide and remember, always work safely.
