A safety tether is provided for securing a heavy work tool. The safety tether includes one or more springs that serve to carry some of the weight of the work tool. A safety chain is provided in parallel connection with the springs. The length of the chain is less than the extended length of a spring at its maximum rated load, thus precluding extension of the springs to that link, greatly reducing any likelihood that the springs will break. In the event of spring breakage, the chain serves as a safety chain, stopping the tool from falling. |
