Qingyuan County of the state Crane Co., Ltd. is a production and sales as one of the modern enterprise. My company has a number of excellent and experienced workers, factory since its inception, adhere to perfection for the purpose, with a full-time quality manager and advanced production and testing equipment, products from raw materials to every aspect of production are layers of strict checks. Libang company recently introduced a new multi-functional hoist, lifting weight up to 5 tons, lifting height up to 100 meters, this multi-functional hoist, an advantage set electric hoist and hoist in one of the lifting products, more suitable for small spaces lifting operations, this hoist with lifting speed, the machine voltage stability, lightweight body, multi-functional hoist models were 220V, 380V, from 7 liters per minute -14 meters, multi-functional hoist to buy the election VIKING manufactured, would like to know more features multi-functional hoist, you can contact the Company is the rise of China in recent years a number of new advantages industries that in the past period revealed comparative advantage index of less than 1, the last 3 years has been greater than one. Most likely to be the potential advantages of industrial concentration in global product space of the central region, from the type of industry, the same focus on machinery and equipment, chemicals. "CaiWeiCi said," Do not belittle that China's equipment manufacturing or mechanical industrial competitiveness is not worth mentioning, in fact, on a number of outfits and the host country has a strong competitive edge. "" Select computing hoists standard "Module establish a common motor hoist equipment, high-speed end coupling, reducer, low-end coupling, wire rope, bearings and high strength bolts of database and computational tasks selection In this module, enter the original design parameters, operating parameters can be done automatically by the computer from the database that match the selection criteria checking, and outputs the selection result, provide the raw data for the optimal design. "lifting machine spindle device structure determination "module, by the original input parameters, according to the relevant formula, to prevent interference geometry, automatic calculation of parts and assembly dimensions of the components of the spindle device. Parts to be simple structure, easy processing, easy to install." The first elevator shaft mounted discrete Optimization Design "module checking spindle drum strength and stiffness, optimizing the structure parameters of the spindle apparatus, including roll thickness, the thickness of the outrigger wheels, support wheel thickness, spindle diameter establishing geometric constraints, performance constraints, structural constraints and other constraints conditions, based on the weight of the lightest and the spindle apparatus stress difference is a minimum of two round multi-objective function, complete the optimization of the structural parameters of the spindle apparatus, the spindle structure parameters means more reasonable.
