AQ-LDY electric single girder crane confirms to JB/T 1306-2008 national standard of China. This overhead crane should match with YHII model electric hoist. AQ-LDY model crane belongs to metallurgy overhead crane, which is designed to lift molten metal in high temperature. Metallurgy single girder overhead crane is able to lift loads weighting 1 ton to 10 ton, and its working class can reach A6. Different from other types of overhead electric crane, AQ-LDY model crane has better heat resistance ability, it can work in factories temperature below 60℃. Besides, this type of crane has low noise, it controls noise under 85dB.

As the necessary crane equipment and lifting device to improve labor efficiency in modern industry, overhead metallurgy crane consists of three parts, crane span structure, metallurgy electric hoist and electrical system. Overhead crane span structure is made up of metal structure and running units. And metal structure includes main beam, end beam and main end beam. Running units consist of driven unit, transmission device, brake system and wheels. As the main running carrier for trolley, overhead singer girder crane is used to support the objects moving in longitudinally direction. Metallurgy electric hoist takes the responsibility of decreasing and raising loads. All overhead crane parts adopt high quality component or famous brands in the world, for example, the lifting motor of crane uses conical rotor motor to make sure a strong starting torque of overhead bridge crane. What’s more, crane cable, no matter for transporting power or lifting objects, adopts heat resistance material. For electrical equipment, like motor, they all adopt heat insulation protection measures.

AQ-HD model adopts advanced unique single crane design, it has small size, light self-weight and less wheel pressure. This model is the most advanced overhead crane in single girder crane. Compared to traditional cranes, this crane has the shortest critical distance from crane hook to wall surface. Besides, lowest head room makes a higher lifting height, which means a better use for factories space. For its low headroom, you can design your plant space smaller but have a more complete function. And what is more, when you choose this crane for its low head room, you can save a big money at the same time, it includes the early construction investment, long term heat supply, air condition and other maintenance cost. The top running overhead crane has perfect crane parts, for lifting motor, we use three in one ABM motor, which saves space and narrow limit size. Then, we use ABB or SEW type for running motor. You can choose the solution level for B, F or H level, and protection level for IP54, IP55 and IP65. If you want a higher protection level, you can choose your own customization as well.
