Abstract
The invention discloses a mono beam overhead crane. The mono beam overhead crane comprises two end beam rails which are arranged in parallel in a spaced manner in the front-rear direction and a beam frame composed of end beams on the two sides and a main beam for connecting the end beams on the two sides. The beam frame is driven by a cart to move on the end beam rails in the front-rear direction. A main beam rail is arranged on the upper rim of the main beam in the length direction of the main beam. A trolley capable of moving on the main beam rail in the left-right direction is arranged on the main beam rail. An electric hoist used for craning heavy objects is arranged on the trolley. A power supply guide rail formed by splicing multiple sliding wire guide rails connected with a power source is arranged on the main beam rail in the length direction of the main beam rail. The trolley is provided with two current collectors which are capable of making contact with the sliding wire guide rails for taking electricity and are electrically connected with the electric hoist. The effect that the two current collectors cannot be located in a sliding wire guide rail spliced seam of the power supply guide rail at the same time is guaranteed due to the distance between the two current collectors. The mono beam overhead crane has the beneficial effects that the phenomena of blackout and phase loss of the current collectors can be prevented effectively, and use safety is high.
