Top Running Single Girder Bridge Crane

The crane can be equipped with a device such as a motor grab and an electromagnetic chuck to meet the needs of lifting various types of materials. The working level of the crane is A3~A7, and the common lifting weight is 3~250t. It is suitable for loading and unloading work at factories, warehouses and freight yards with an ambient temperature of -10C-40C and a relative humidity of not more than 85%. It is forbidden to work in a flammable, explosive and corrosive atmosphere.

Safety routine inspection, inspection items and points are as follows: 1, lifting height limiter, travel limit switch and interlocking mechanism performance is normal, safe and reliable, 2, all major components meet safety requirements: opening increase is smaller than the original 15% of the size, the torsional deformation is less than 10%, the plate hook bushing wear is less than 50% of the original size, the plate hook mandrel wear is less than 5%, no peeling, burr, welding repair. Hook hangers and pulleys have no obvious defects. The wire surface of the wire rope is worn and corroded by less than 40% of the wire diameter. The broken wire is less than 10% of the total number of wires in a lay length. No breakage, no obvious thinning, no core disengagement, dead angle twisting, and extrusion deformation. , annealing, burning phenomenon. The ends of the wire ropes are connected and the clamps, pressure plates and clamps are well connected, there is no looseness, the pressure plate is not less than 2, and the number of clamps is not less than 3. There is no crack in the reel, no looseness in connection and fixing, the wall wear is less than 20% of the original wall thickness, the safety roll is not less than 2 turns, and the diameter ratio of the reel and the wire rope meets the requirements. The balance wheel is fixed and the wire rope should meet the requirements. The brake has no crack, no looseness, no serious wear, and the brake gap is equally sized on both sides. It has sufficient braking force and the brake band wear is less than 50% of the original thickness.

Through the safety routine inspection of the double girder bridge crane, it has played a significant role in eliminating personal accidents, reducing equipment accidents, improving equipment operation rate, and reducing maintenance costs. Single beam crane, double beam crane maintenance, repair, transfer, transformation, annual inspection, acceptance and certification services. Maintenance of single and double beam cranes includes the installation of overload limiters, replacement of wheels, operation of sports cars, lifting limit repairs, maintenance of large car brakes, repair of spare parts of trolleys, lengthening and shortening of main beams. Maintenance of single and double beam cranes: Regular inspection of cranes, replacement of parts and maintenance is required. Track part: Whether the track accessories can be repaired, whether the connecting plate is firm, whether the track is vertical, and whether there is unevenness.
