Abstract
A mining sled with a movable bed. The movable bed nests within the sled and is slidable with respect to the sled. Stops are located on the sled to limit the distance the movable bed can travel with respect to the sled. The movable bed includes brackets at a first end for attachment to the pull-out rope of a pull-out winch. The second end of the movable bed includes a mount for attachment of a pulley. The pulley on the movable bed facilitates attachment to a pull-in rope that is connected to a pull-in winch for transporting the sled toward the continuous miner.
