Chain hoist with the use of metal structural deformation how to do?

Demand for electric chain hoist is a  Hoist equipment  is relatively large and specifications are also more general chain hoist with electric sports car to be run on the beam orbit using their knowledge about the device in front of quite a number of articles did introduce today to introduce you to use if the chain hoist with metal structure to deform, how to do?

Cause deformation of the metal structure hoist is mainly due to stiff problems, a common structural deformation of the case in the main beam and cantilever span appear under torsion, lateral bending, the main beam webs appear super wave transformation required by the main beam, end beam frame structure composed of diagonal tolerance deformation. Torsion deformation under the main beam of the  manual hoist  electric sports car track appears slope, slope climbing trolley increased resistance, which would produce a run slip show, even after stopping slippage.
Then appear above the metal structure deformation problems how to do? Solve hanging deflection under load, the main beam is designed to have a certain degree of pre-camber, the cantilever end is designed to bend a certain degree, so that the elastic deformation of the main beam curve in terms of load or full load are more gentle. But with the passage of time using the  rope hoist , the role of long-term load inevitably make camber and upturned decreased, then there under torsion deformation. Some causes deformation of the metal structure in the manufacturing process of the residual stress generated during installation defects overload during use, the impact of the working environment temperature, the normal long-term effects also cause deformation of the load, the non-normal factors accelerate the process of these variants.
