Part Five

This feature is a continuation of Part One which explains the concepts for this discussion.



There are situations where a natural or vehicle based anchor points may not be practical or desirable. One practical alternative involves what's known as the 1-1-1 picket anchor system. This system utilizes 48-inch or 42-inch pickets that can be arranged to create a reliable anchor system in most soils. The pickets should be cold rolled steel so as not to deform when being driven into the ground.

We utilize 42-inch duplex pickets with webbing tiebacks so they won't shift or work loose under a load. The duplex heads will prevent the webbing from slipping and can the duplex heads can also be used to suspend pulleys, etc.

Tipping the picket heel to toe will produce a functional angle.

Drive 2/3rds of the pickets into the ground.
(We use green markers on ours.)
Spacing the pickets.

Utilize webbing to provide safer positioning of
pickets if wobbling when struck on difficult to drive ground.
Properly tensioned system with load applied to the base using webbing.

Attaching a pulley to the top of a picket for light load change of direction.

Attaching a pulley to the top of a picket to relieve friction on a rocky edge.

  Quick Summary

ALWAYS set up a 1-1-1 system in direct line with the load.

ALWAYS Tip pickets away from the load "heel to toe" and space one picket length apart.

ALWAYS drive pickets 2/3rds deep. If the pickets won't drive to proper depth, choose a different location.

ALWAYS safety check a 1-1-1 system for proper rigging before applying a load.

ALWAYS observe the pickets for movement or shifting when the load is applied or if the load changes significantly, such as getting hung up during the haul.

Whenever practical use a second anchor point with a progress capture device as a safety line when operating on steeper slopes.
