High rise elevator wire rope method?

A wire rope method
1) the main equipment of the elevator has been installed, the car chassis has been adjusted, the safety clamp has been clamp.
2) assembly and car weight frames at the top level (counterweight temporarily put), hand pulling hoist hook frame.
3) at the top floor of the hall, put up a temporary release rope rack, will be put on the shelf of each bale of wire rope, should be able to turn flexible, easy to put on the rope.
4) to make one end of the wire rope rope, in accordance with the requirements of the steel wire rope from put the rope frame, wooden, car top round, guide wheel, counterweight pulley, rope is fixed in the room rope head plate.
5) check the elevator shaft, the counterweight frame without hindrance decline. At the bottom of the hole, the position of the frame sliding down or the temporary support is provided to ensure the accuracy of the length of the wire rope.
6) weight frames fell to specified location, on the top floor with rope clip will every piece of wire rope and hand pulled hoist wire rope clamping, prevent the decline of framework. Then make the other end of the rope, hanging to the rope fixed on the first board, the end of the rope.
7) staffing: Room 2 for brake rope device; each bundle of steel wire rope the by a master to put the rope; in order to ensure put the rope speed, is composed of a command is responsible for the; well Daowai arrangement 1 patrol officers, the man ran along the bottom of the stairs, with the tightness of radio reporting framework decline the position and the rope.
Two safety measures
Weight frame when the wire rope traction machine brake device is inoperative. With the decline in the framework of the framework, such as the speed of the speed of the decline of the speed control measures will be more and more fast, may lead to accidents. Therefore, in the course of the rope to take a slow speed, brake rope measures, can slow down or stop at any time.
1) slow speed measures. In the car on the column of the temporary binding 2 root stout timbers, so that each piece of wire rope to s coiling the root timbers to car crown chakra and increase steel wire rope sliding friction, the frame slow slip.
2) brake rope measures. In the room of the traction wheel, left and right with a 50mm thick, and the traction wheel is equal to the width of the board, the end of the top on the frame of the traction frame, board 1 / 3 of the paste on the rope of the traction wheel. The rope to deceleration or braking, as long as at the other end of wood with a certain force, will be able to check all wire rope.
Comparison of three two methods of line release
1) is one of the conventional rope. If the elevator wire rope is around 2:1, respectively, each rope into the bottom, and then pull the hoist to the top. Not only time-consuming, Fei Gong, and easy to put the wire rope chaos, but also easy to hand with the scaffolding steel. The counterweight frame to put the rope, wire rope can be discharged, will not appear the situation.
2) the operation of the wire rope should be checked up and down by the operator in the well path. 20 floors above the elevator requires several people at the same time doing this work, both hard and waste of labor, and not safe. And now no matter how high the floor, as long as the 1 inspectors can be completed.
3) conventional release 20 1 floor elevator rope needs 1 days, and now even ready to work as long as the 2H, the rope speed increased 3 ~ 4 times. If the building of the higher floors, elevator units more, more is to save time.
Practice has proved that this method is applied to the installation of high-rise buildings with the advantages of time saving, labor saving and safety.
