QD type 5-50/10 ton slow-speed hook bridge crane

qd type 550/10 ton hook bridge crane

The main lifting rated capacity of this crane is 5 to 50 tons, and the auxiliary lifting rated capacity is 10 tons. This parameter combination can meet the lifting requirements for various different weight goods, such as in the mechanical manufacturing workshop, it can lift different specifications of components.

The bridge structure of this crane is made of high-quality steel by welding, with high strength and rigidity. According to relevant standards, it can withstand the specified load without obvious deformation, ensuring safe operation. The lifting mechanism uses advanced planetary gear reducers, with high transmission efficiency and low noise. Compared with traditional reducers, it can reduce energy consumption by approximately 15% under the same working conditions. The electrical control system has complete protection functions, such as overload protection, short circuit protection, etc. When the lifting weight exceeds 110% of the rated value, the overload protection device will be triggered automatically, stopping the lifting action. The wheels of the running mechanism are manufactured by forging process, the tread hardness complies with relevant industry standards, and after special heat treatment, the wear resistance is significantly improved, and the service life is extended by about 20% compared to ordinary wheels.

The braking system of the crane uses electromagnetic brakes, with rapid and reliable braking, the braking response time is less than 0.2 seconds, and it can stop the crane operation in an emergency situation in time. The operation room design conforms to the principles of ergonomics, with an open view, equipped with comfortable seats and operation handles, the operating handle manipulation force complies with national standards, and it is not easy to get tired after long-term operation. The main girder of the crane is manufactured with an arching degree in accordance with the specified requirements, the arching value is 0.9/1000 to 1.4/1000 of the span, this design can effectively reduce the sagging deformation of the main girder when bearing. The hook is forged from high-quality alloy steel, after flaw detection, it is ensured to have no defects, the opening degree wear limit complies with relevant specifications, when it exceeds the specified value, it needs to be replaced in time, the lubrication system uses an automatic lubrication device, which can lubricate each key part at regular intervals and quantitatively, reducing component wear, for example, lubricating the bearing can reduce the working temperature of the bearing by about 10℃.
