導軌采用(yong)熱(re)鍍鋅(xin)、硬軋鋼結構，S250GD + Z275-M-A-C 板(ban)冷成型，材料符合(he) DIN EN 10147（材料規(gui)范）和 DIN EN10143（尺寸公差 )，鍍鋅(xin)表(biao)面處理 (140g/ m2 , 9.8μm 厚度 ) 雙面應用(yong)，焊縫外熱(re)鍍鋅(xin)。 

注(zhu)意：禁止將安全鉗與(yu)配(pei)重側的導軌一起使用。 

Guide rails are cold formed from hot galvanized, hard-rolled constructional steel, S250GD+Z275-M-A-C plate. The material follows DIN EN 10147 (material specification) and DIN EN10143 (tolerances on dimension). Zinc coating surface treatment (140 g/m2 , 9.8μm thickness) is applied on both sides. Welding seam is externally hot galvanized. 

NOTE: It is forbidden to use the safety gears with these guide rails on counterweight side.
