Elevator installation quality verification of Frequently Asked Questions 1, the limit switch is installed to protect the position of the counterweight with the process and test elevator hoisting and Dun bottom is one of the elevator malfunction, though not common, but once occurred sightseeing elevator price for Make sure the motor to stop in time, GB7588-1995 "elevator manufacturing and installation of safety norms" provides elevator limit switch should be set. Because it does not expressly provide for the installation location, formed from different manufacturers have different design and installation requirements. GB 10060-93 acceptance of existing Article 4.6.5 Action test specified upper and lower limits: Set in the limit position protection switch upper and lower ends of the shaft, it should be touching the car or on the front bumper weight work, and is compressed in the buffer to maintain its status during operation. The emphasis here before touching elevator buffer function, its purpose is to require the front bumper is compressed cut off the electrical power supply, the brake is closed in order to ensure that the car stopper. Section 4.5.1 also provides: a car at both ends of the station leveling position, the car, hit the plate distance counterweight buffer between the top surface (here with S1, S2 shown), energy-consuming buffer should be 150 ~ 400mm elevator manufacturers, energy storage buffer should be 200 ~ 350mm. Such as the one on the test project, the site installation phase to meet the requirements should be easy. Elevator installation quality verification common question 2, the elevator test GB10060-93 4.6.7 stipulates that the elevator test, provides that: the car load, respectively, 50% of the rated load and rated load three conditions, and in electricity sustained rate of 40% cases, reach the entire travel range, at 120 times / h, not less than 8h per day, each starting and braking run 1000 times, the elevator should run smoothly, brake can be *, continuous trouble-free operation. But in the field of quality verification and verification of information often found the following problems. 2.1 test conditions do not meet the regulatory requirements for elevator test shall be under three working conditions separately. Where no-load and full-load operation test run test is the test specification under two kinds of important working conditions. For assessment focuses on the balance of the car and the elevator brake under these two kinds of working conditions is available * elevator leveling accuracy and other properties. Found at the scene often overlooked load and full load conditions demands, or 20%, 80% of the rated load replace, or does not consider the working conditions do not meet the requirements are.
