Product improvements for bridge cranes

 Bridge crane is Hengjia in workshops, warehouses and empty field for material lifting material lifting equipment. It is located in the ends of the tall concrete pillars or metal bracket, shaped like a bridge, named  overhead gantry crane .  Overhead crane overhead bridge along the laying of tracks on both sides longitudinally running, you can take advantage of the space under the bridge lifting material from ground equipment obstacles. It is the most widely used, the largest number of a lifting machinery. Bridge crane bridge crane can be divided into ordinary, simple beam bridge crane bridge crane and metallurgical dedicated three.
Overhead  sino hoist  in use and easy off, sometimes in the transmission conduit sparks some serious blasting trolley line, causing the collector replaced too frequently, affecting production. Therefore, it is necessary to bridge crane were the following improvements:
1 increase in collector between two opposite brush spring strength, flexibility, ensuring spring return freely;
(2) increasing the collector brushes chamfered and polished smooth;
3 deepened. Reinforcement collector in a spring seat, the return spring to ensure the brush is not easy in the work string position;
4 two safety trolley line connections connecting block should be chamfered to ensure a smooth transition collector. Meanwhile,bridge gantry crane to ensure the safety of the normal use of the trolley line, driving workers standardize operations, maintenance workers of periodic maintenance, periodic inspection is also essential.
