hoist equipment mast distortion correction method can be eliminated

Electric forklift mast distortion correction method can be eliminated. When bending and twisting deformation is small, allowing the cold calibration correction method applied motorized chain hoist static load . When bending , distortion is too large, correction is difficult to use cold , heated correction should be heated to minimize the heating zone , the heating temperature is generally not more than 700 ℃, and slowly cooled so as to increase brittleness.three phase electric hoist mast crack repair : If the inspection found cracks should be repaired .repairs should be carried out before the forklift mast correction , maintaining the inherent straightness mast .grinding cracks to expose the metallic luster , and then carefully examined to determine the boundaries of the crack extends 10mm at the boundaries of the drill ¢ 5 - ¢ 8mm of limiting, holes.
