The GRCS Device is easily attached firmly to a tree trunk. The complete unit features a modified Harken 46 winch that separates from the mount for easy setup. The tree mount is hinged, offering flexibility when attaching to a variety of stem diameters.
The rubber feet on the tree mount help protect the cambium if the tree is not to be removed. The aluminium bollard is interchangeable with the winch head. All aluminium construction ensures optimal friction heat dissipation on the bollard.
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.
In 2012, the GRCS was updated with an improved winch, the Harken 46 Arborist. It has a taller drum, allowing for a full five wraps with a 19 mm lowering line. The self-tailer is modified to accommodate the larger diameter ropes used in our industry.
