Good Rigging Control System (GRCS)


Greg Good's, Good Rigging Control System, or GRCS, gives you the mechanical advantage you need to safely raise and lower large tree branches.

The Good Rigging Control System (GRCS) was created by Greg Good of Wisconsin and is an essential tool for any arborist team that encounters large removals. When you combine its easy setup, lifting power, and tangle-free operation you truly get the ultimate system for lowering large limbs with the most control possible, especially when the site must be preserved from damage. Another great use of this tool is its side pulling power which comes in handy while working on those big storm damage jobs.

The mounting plate of the GRCS is mounted firmly to the trunk of the tree with a 20-foot cinch strap and is tightened with a 36-inch tensioning bar. The hinged side plates and 9 rubber pads allow for installation on a wide range of stem sizes while protecting the tree from damage. Once the bracket is installed the Harken 46 Arborist easily slides in and is held in place with a retaining pin. In 2012 the system was upgraded to this winch with taller drum than the previous and it allows ½ to ¾ inch lowering line to be wrapped a full five times. This winch has a dead-lift rating of 3,000 lbs. and has two settings that provide both a 44:1 and 22:1 mechanical advantage. When you add in the self-tailing feature of this winch It becomes a breeze for a single ground person to safely lift, lower and lock off loads without tying knots. The aluminum rope break dissipates friction heat and features a welded 4-inch diameter tube that is large enough for an ice pack to be placed inside during extreme lowering situations to prevent rope glazing. With this aluminum break the GRCS has a Working Load Limit (WLL) of 2,000 lbs.

The GRCS includes the mounting plate, strapping, tension bar, and winch. There are many accessories available for the GRCS that extend its application and ease of use. This system is an investment that will allow for more work opportunity and quickly pays for itself. It is a good tool for crews without the use of a crane or when a jobsite restricts the use of large equipment.
