Many customers who purchase a regular electric hoist know that there is an instruction manual that follows the electric hoist to the customer, which contains the installation steps of the electric hoist. In fact, the installation of the electric hoist includes two steps: track installation and electric hoist installation.
Track installation: 45° joints are used at the track connection, and the groove is answered. Before welding, carefully clean the groove and nearby oil, rust and slag leftover from cutting. When aligning, leave a gap of 2mm and pull the wire to ensure the straightness of the two butted rails is within 5mm, and fix it by spot welding. When welding, first weld the bottom of the track, then the top of the track, and then weld the waist of the track. After the welding is completed, re-check the straightness, and polish after meeting the requirements to ensure the smooth walking position of the electric hoist trolley. Before the track is installed, the end face, straightness and twist of the rail should be checked and adjusted, and it can be installed only after it is qualified. The deviation of the actual centerline of the track from the horizontal position of the installation reference line shall not be greater than 3mm. When butt welding is used for rail joints, the welding rod should meet the requirements of the rail base material, the welding quality should meet the relevant regulations of electrofusion welding, and the top and side welds of the joint should be polished flat and smooth. The constant surface inclination of the I-beam track should not be greater than one hundredth of the track width. Installation of electric hoist: adjust with adjusting washers during installation to ensure that the gap between the inner side of the wheel flange of the electric hoist and the flange of the I-beam track should be 2-4mm. In order to ensure that the electric hoist does not derail or damage the body of the electric hoist to the ends, rubber block car stops are set at both ends of the track. The ground resistance of all power circuits and control circuits of electrical installations shall not be less than 1000 ohms per volt of working voltage.
