Description
The Good Rigging Control System--or GRCS--is a complete lowering and lifting device. Developed by Greg Good, the system features a powerful Harken winch adding either a 44:1 or 22:1 mechanical advantage for serious lifting power. Replace the winch with the included bollard, and you are ready for serious negative rigging and lowering heavy loads with ease. With a dead lift rating of 3,000 lbs, the GRCS generates the lifting power and pulling power to handle tremendous loads quickly, and in a safe and controlled fashion. Gain a real mechanical advantage in your next equipment investment with the Good Rigging Control System: GRCS--the ultimate tool.
Details
GRCS – The Good Rigging Control System
The Good Rigging Control System (GRCS) is the industry’s leading lowering and lifting device designed specifically for professional arborists. Combining power, precision, and reliability, the GRCS allows a single operator to safely control and move heavy loads in complex rigging situations. Whether you’re lowering massive trunk sections or lifting limbs clear of obstacles, this system provides unmatched control and efficiency on every job.
Unmatched Lifting and Lowering Performance
Built around a robust Harken self-tailing winch mounted to a high-strength aluminum base, the GRCS converts manual effort into exceptional mechanical advantage. Its innovative design allows operators to lift or lower loads smoothly and safely—delivering up to 3,000 lb of lifting power and controlled lowering with minimal friction. The system’s winch drum ensures precise line handling and reliable grip on every pull.
Engineered for Arborist Applications
Developed by working arborists, the GRCS is purpose-built for tree removal, rigging, and controlled lowering. Unlike generic winching equipment, the GRCS mounts directly to the tree using an adjustable mounting plate and heavy-duty straps. This setup eliminates the need for bulky machinery, allowing climbers and ground crews to handle large pieces of wood safely and efficiently while maintaining total control from the ground.
Fast, Secure Mounting System
The GRCS features an adjustable mounting plate and ratcheting strap assembly that secures quickly to a wide range of tree diameters. The system can be installed and ready for use in minutes, saving valuable time on complex removals. Its durable construction resists impact, corrosion, and weathering—ensuring long service life even in harsh outdoor conditions.
