Abstract
A Multi-Armed Lifting Accessory is disclosed herein which is compact and transportable in various deployments. The Multi-Armed Lifting Accessory is advantageous and useful as it has hingedly connected loading and support arms attached to a main lifter body. The supporting arms are spring loaded allowing the Multi-Armed Lifting Accessory to stably engage with irregular shaped objects such as barge lid or a skid steer loader and allows for flexible engagement and balanced lifting operations.
