  • Patent number: 7824144
    Abstract: A hoist with a cradle for coupling with a pressurized tank. A primary means of restraining the tank on the cradle is provided along with a backup means should the primary means fail for any reason. A linear actuator assembly raises the cradle up to 27 inches from the floor surface. An onboard battery with an integrated battery charger provides power to the linear actuator. A compact base with swivel casters allows a raised tank to be safely lifted and transported by a single operator. The compact size of the hoist allows it to operate in confined spaces.

  • Patent number: 7789611
    Abstract: A hoist with a cradle for coupling with a pressurized tank. A linear actuator assembly raises the cradle above the floor surface. A base with casters allows a raised tank to be safely lifted and transported by a single operator. The cradle can be rotated and locked in a vertical or horizontal position for cylinder insertion and removal in EMS vehicles with either a vertical or a horizontal stowage compartment. When handling a horizontal cylinder stowage situation, an embodiment of the cradle features a retractable foot to allow the cylinder to be slid from the cradle into the compartment bottom first. Another embodiment has a fixed foot and allows the cylinder to be slid from the cradle into the compartment top first. Safety interlocks are provided to prevent rotation of the cradle if the foot is in the wrong position with respect to the horizontal orientation of the cradle.
