The Altec Heartland product line consists of an Effer knuckle boom crane, a 360-degree continuous-rotation grapple saw (33-inch jaw opening, 14-inch cutting depth, 3,300-pound maximum lift capacity) and radio remote controls. These units were designed to allow operators to cut limbs and branches without ever having to leave the ground or touch a piece of the tree. The EC225-6S-FG model provides an additional seven feet of cutting height and has a rear-mounted configuration, allowing operators to set-up 10 to 12 feet closer to the tree.
