    Using a 4x4 as a winch anchor for a lifting rig

    [smile] Perhaps this attachement will help? Only focussing on the horizontal pull, but may need to consider a 10degree gradient. Presumably load capacity is dependant on weight and ground friction but how to i calculate this, do I need to consider wheel base and load distribution on the...

    Using a 4x4 as a winch anchor for a lifting rig

    Hi, can anyone help with this query? Looking to use a 4x4 as an alternative to a ground anchor such as a platypus. The 4x4 will be the anchor point for the winch as part of a lifting rig. Assuming flat ground conditions how would I calculate the load capacity of the ground anchor (I.e the...
