PURPOSE: An escalator for a moving unit with a wheel and a dual lift wheel are provided to enable an existing moving unit to go up and down a slope without a separate power source since a lift wheel is installed on the existing moving unit. CONSTITUTION: An escalator for a moving unit with a wheel and a dual lift wheel are as follows. A caterpillar track and a power source are attached to the guide line of a main wheel on a slope to realize an elevator for the slope. The dual lift wheel forms an inner wheel of a concave H shape. The wheel of the moving unit makes contact with the concave surface of the inner wheel and receives the power of the lift wheel. The inner wheel transfers the power to the wheel of the moving unit and simultaneously rotates with it. The lift wheel has torque using the power of the elevator on the slope without a separate power source.
