Abstract
An apparatus including a main housing including a generally horizontal platform, a boom extending from the platform, a bucket suspended from the boom, and a mast extending from the platform. The apparatus further includes a boom support strand extending between and attached to the mast and the boom, and a boom support strand oscillation dampening mechanism. The boom support strand oscillation dampening mechanism comprises a left brace and a right brace spaced apart from the left brace, and a polyester rope extending between each of the braces and the boom. Each of the ropes is attached to the boom. A device attaches the rope to the brace, and a boom support strand clamp mechanism is connected to the brace and includes a first clamp block, a second clamp block, and a flexible enclosure placed between the first clamp block and the second clamp block. The boom support strand is within the flexible enclosure, and the flexible enclosure has a length, as measured from its midsection to either end of the flexible enclosure, of more than 2 times longer than the inside diameter of the flexible enclosure. A mechanism holds the first clamp block to the second clamp block so that the flexible enclosure is clamped between the first clamp block and the second clamp block.
