Reference 70™ 螺栓
REF 70™ 斗提机螺栓

REF 70™ 斗提机畚斗螺栓等级为 ISO 5.8 级,螺栓头一面呈现圆弧形曲面,另一面上带有 4 个对置的凸点,凸点的作用是拧紧螺栓时防止转动。REF 70™ 畚斗螺栓配合大椭圆垫使用时,最适合安装皮带轮直径大于 50 厘米的重工业钢制畚斗。因为这种螺栓有圆弧形的曲面,这种螺栓不适合安装后背平直的塑料畚斗,尤其不适用薄皮带。

产品细节

Is the installation of Ref70 bolts any different to other elevator bolts?

When using the large Reference 70™ (REF 70™) oval washer with the REF 70™ bolt, the washer should be placed with the widest part across the belt in order to minimize stress on the system as it passes around the curved pulley. 

Note:  the bolt head and oval washer are installed on the back of the belt.
