Elevator installation quality verification in FAQ 2.2 elevator starting and braking operation frequency does not meet the requirements specification by 120 times / h Elevator decoration, decoration day, less than 8h elevator, each starting and braking 1000 times, in such a starting and braking frequency, this test should normally be completed within 3 days. However, installation companies, we found that the self-test data, this test lasted four days, five days elevator decoration, or even longer, but did not increase the number of runs. This greatly reduces the severity test, but also reach the purpose of the assessment lift capability of continuous operation. 2.3 does not do continuous trouble-free operation. Elevator installation quality verification in FAQ elevator balance coefficient is related to the performance and operation of the elevator drive power output device size is an important parameter. After the elevator installation, due to material errors or the car may change the decor, the actual weight of the car will deviate from the design value. Therefore, before commissioning the elevator, the elevator balance coefficient must be determined decoration offer, to ensure compliance with the design requirements. When equilibrium coefficient test, load weights should be used when conditions do not have to replace with other heavy objects, should the weights were weighed, and the weight can not be estimated. Such as bags of cement to do load, just by the subject of the bags weight load, or to the people doing the load, * estimate a person's weight to calculate the load, such practices are not standardized. Usually determine the equilibrium factor drawing current - load curve, upward, downward running curve intersection to determine. GB 10060-93 Section 4.6.1 provides a balance factor should be 40% to 50%. To make the curve more accurately, it should be 40% and 50% of the rated load and take some around. According to GB / T 10059-1997 "elevator test" Article 5.1.1 "on the elevator balance coefficient Nanchong elevator decoration decorative fee _ _ Gordon Metal Products offered by Chongqing Gordon Metal Products Co., Chongqing Gordon Metal Products Ltd.
