2015年10月8日 — Overhead crane camber restoration There are two ways to restore the deformed crane girder, the traditional Flame Correction Method and Prestress Correction Method. The principle of flame correction method is to heat the three sides of the girder and cool it down to reform the girder camber.
When selecting an electric overhead traveling crane, there are a number of Typical examples are cranes in repair shops, light Examples include hot metal carriers, twin hook hoists used to move hard to balance loads, 2) The girders shall be designed with positive pre-camber and the vertical deflection caused by the.
