What safety matters should be paid attention to when installing the guide rail of elevator?
7588 - 4.2.1, each rail should have at least 2 guide brackets, and its spacing is not greater than 2.5m.7588 - 4.2.1 with the weld welding support should be continuous, and should be double welded.The 10060 - 4.2.7 car rail and the counterweight rail with the safety clamp shall be supported on the solid rail seat at the lower end of the road.The distance between the top of the car guide rail deviation is 0 ~ +2mm.The distance between the top of the heavy rail deviation is 0 ~ +3mm.10060 - 4.2.3 each rail working face (including side and top surface), the deviation of each datum line of the installation datum line shall be no more than the following value: the car rail and the counterweight rail with the safety tongs are 0.6mm, 5m.10060 - 4.2.3 without safety tongs, T type counterweight rail is 1.0mm.10060 - 4.2.3 piecewise continuous test on each 5m plumb line (at least 3 times), 2 times of the maximum relative deviation of measurement value should be less than the prescribed value.10060 - 4.2.3 piecewise continuous test on each 5m plumb line (at least 3 times), 2 times of the maximum relative deviation of measurement value should be less than the prescribed value.10060 - 4.2.4 car rails and counterweight rails face joint is provided with a safety gear should be continuous at the gap, and the local gap is less than 0.5mm, no safety gear of heavy rail joint gap should not be greater than 1mm.10060 - 4.2.4 rail joints, the steps should be no more than 0.05mm, without the security clamp on the heavy rail, the joint shall be no more than 0.15mm.10060 - 4.2.4 light length is more than 150mm.
