The Good Rigging Control System created by Greg Good (GRCS for short) is an essential tool for any professional tree crew working with large timber. When using the winch, the GRCS helps with lifting downed limbs and trunk sections - especially helpful on storm cleanup jobs - thanks to the Harken winch adding serious lifting power to your crew. The GRCS is the ultimate lowering tool for bringing down heavy wood with control, and shines when working on a site which must be preserved from damage.
In 2012, the GRCS was updated with an improved winch, the Harken 46 Arborist. It has a taller drum, allowing for a full 5 wraps with a 3/4" lowering line. The self-tailer has been changed to accommodate the larger diameter ropes used in our industry. The new version was found to be just as tough and that it provides even more pulling power!
The GRCS is an equipment investment which quickly pays for itself, allowing a crew to tackle jobs they might otherwise need a crane for, thanks to its lifting power.

“This device is worth every single cent you spend on it. When you use it, you guarantee that nothing is gonna fall and damage anything underneath.”
The aluminum rope brake on the GRCS provides a large surface for taking wraps making this tool the ultimate in controlled lowering. The aluminum rope brake dissipates friction heat, and the heavy duty fairleads ensure proper line angles. Using the aluminum rope brake, the GRCS has a Working Load Limit (WLL) of 2,000 lb.
The Harken capstan winch on the GRCS has two settings providing a 44:1 and a 22:1 mechanical advantage, and a dead-lift rating of 3,000 lb. Multiple fair leads position the rope on the winch drum to keep operation tangle-free. The 2-speed self-tailing winch allows a single ground person to lift, lower, and lock off tremendous loads quickly, safely, and without tying knots.

The GRCS attaches firmly to the tree trunk with a 20' cinch strap tightened with the included 36" tensioning bar. Rubber pads on the mounting plate protect the tree from damage and ensure a good hold for the unit. If protecting the tree is not a concern, an additional visor mount is available which can be placed in a kerf cut into the tree to help keep the unit positioned correctly when rigging very heavy loads.
