吊车用钢轨一般说明

    下列A.S.C.E.钢轨及104~175磅吊车钢轨推荐用于吊车轨道。有关完整的详细资料以及未列出的钢轨的剖面和特性,请查阅生产厂的样本。

    吊车钢轨的拼接应使吊车轨道相对两边的接头彼此和与轴距错开。轨道接头不得位于吊车梁拼接处。40磅轻型钢轨的供货长度过30英尺。60磅钢轨的供货长度为30,33或39英尺,标准钢轨的供货长度为33或39英尺,吊车轨道供货长度最大到60英尺。关于其他长度钢轨的供应情况,请询问生产厂。为补足行程或为实现必要的交错而必须包括的特殊长度的钢轨,其长度不得小于10英尺。用于吊车轨时,40磅钢轨和吊车轨可按生产厂的技术条件和公差提供。60和85磅钢轨可按生产厂的技术条件和公差,或按ASTMAI提供。除非订单上另有规定,凡提供的标准长度钢轨和特殊长度钢轨均具有标准钻孔。有关受控冷却、热处理及轨端的加工,请参见生产厂的样本,吊车轨的订货单上应注明“用于吊车”。
