導軌采(cai)用熱鍍鋅、硬軋鋼(gang)結構，S250GD + Z275-M-A-C 板冷成(cheng)型，材料符合(he) DIN EN 10147（材料規范）和 DIN EN10143（尺寸公差 )，鍍鋅表面(mian)處理 (140g/ m2 , 9.8μm 厚度 ) 雙面(mian)應用，焊縫(feng)外熱鍍鋅。 

注(zhu)意：禁止(zhi)將安全鉗與配(pei)重側的導軌(gui)一起(qi)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.
