The following document outlines the procedure for ensuring successful retention of the load in a NavHoist chain hook. In certain, rare instances when the load is removed from the chain, the unloaded hook may come to rest in an orientation that would allow the load carrying implement (shackle, sling, etc.) to release from the chain hook as load is reapplied.
Note that the procedure outlined below is temporary in nature and the hook may be replaced by a locking hook to permanently address the issue. Contact TAIT Support at email@example.com for more information on replacement hooks.
Please be aware that regardless of the fix used to secure the load in the hook, the operation of the hoist should not allow a chain to become slack. Ensure that all prerecorded and manually operated movement of the NavHoist keeps the chain properly loaded.
Immediately, and then every time a new load carrying implement is fixed to the chain hook.
- Visually inspect the hook for signs of damage.
- As outlined in the picture sequence below, use electrical tape to secure the shackle in the hook to prevent rollout.
