Key specifications

Choosing the right option

Do not treat it as an allowance above the rated capacity.

The stainless steel ID plates and rivets are avoiding dangerous sparking. This makes the blocks suited to underground mining.

The weight shown for the longer lift includes Beaver's extra weight per metre of extra lift.

Choose the rated capacity to suit the heaviest load, allowing for the weight of rigging such as slings and shackles, then the standard lift to suit the height you need. Check the headroom H against the space between your hook point and the load at its lowest, and the effort on the hand chain against the people available.
