What are the installation steps of Wire Rope Electric Hoist?
 Track installation and Wire Rope Electric Hoist installation are included:
 1st, Track installation: 45 degrees joint are used, oil, rust must be cleaned in the groove firstly before welding. Leave the gap within 2mm and pull the wire to make sure two tracks of the docking line within 5mm and use spot welding to fix, firstly weld track for bottom then top, lastly waist, Check the straightness again after welding. Grinding is required to ensure running location of the Wire Rope Electric Hoist is smooth and even, the end face of the rail, straightness and distortion should be checked and qualified Before track installing, Actual track line center to horizontal position line installation deviation should be less than 3 mm. Rail connection uses welding which quality is in accordance with the relevant electric welding provisions that use welding rod. Top and side welding is needed to be polished and leveled, i-steel rail constant surface slope needed to be less than 1% of the track width.
 2nd, Wire Rope Electric Hoist Installation: adjust the washer and the gap between inner wheel rim of Wire Rope Electric Hoist and I-beam rail shall be 2-4mm. a rubber block is provided at both ends of the rail to ensure the hoist on both ends not derailed or touch bad body, power and control circuit of resistance should more than every v working voltage 1000 ohms.
