After the trial hoisting is not abnormal, the hanging basket 2 is lifted to a second preset height, for example, 6 m; then the test is carried out by descending 5.7m (no load), and if no abnormity exists, the test is lifted to the installation height again.

The operation test of the hanging basket 2 specifically comprises the following steps: lifting the hanging basket 2 to a preset construction height through a chain block; connecting a lifting ring 12 on the hanging basket 2 with the steel cable pulley 8; checking and accepting the connection part of the lifting ring 12 and the steel cable pulley 8; connecting the chain block with the top of the hanging basket 2 or the steel cable pulley 8; the gondola 2 is pulled by the chain block to move back and forth along the runway 1 at least once.

Taking the empty loading of the basket 2 as an example, the specific operation test of the basket 2 comprises the following steps: lifting to the installation height in an idle load manner, adopting a steel wire rope, connecting the upper end of the steel wire rope pulley 8 with the steel wire rope pulley, connecting the lower end of the steel wire rope pulley with the hoisting ring 12, and firmly locking the two ends of the steel wire rope pulley by using 3+1 lock catches. And (3) checking and accepting the firmness of hanging points: the space and the fastening degree of the lock catch are mainly checked. The cableway is moved horizontally left and right (moved back and forth twice) on the cableway 1 of the hanging basket 2 in an idle state, whether the cableway 1, the pulley, the sling 6 and the operation platform are in good running state or not is observed. Specifically, referring to fig. 8, the traction rope 15 may be fixedly connected to the intersection of the upper chord 202 of the gondola 2 and the sling 6, the traction rope 15 is connected to the chain block, and the chain block pulls the traction rope 15 to drive the gondola 2 to move along the cableway 1. The pulling ropes 15 are symmetrically connected with both sides of the hanging basket 2.

When the hanging basket 2 is hoisted and tested in operation, the hoisting test and the operation test under the condition of no load of the hanging basket 2 can be firstly carried out; after the hanging basket 2 is installed and checked to be qualified, the no-load operation is normal.

Then, carrying out a rated load test, namely a static load test: the hanging basket 2 is lifted to a first preset height of 300mm from the ground, a rated load weight is stored in the platform, and the stress safety and stability of the bearing structure of the operation platform are observed. And (3) storing a rated load heavy object in the operation platform, lifting the heavy object in a stroke of not less than 6 meters, performing three tests, and recording test results into a running test record table of the hanging basket 2.

Then the rated load capacity is respectively positioned at the left and right eccentric load positions in the hanging basket 2, the lifting is carried out in the stroke of not less than 6 meters, the test is carried out for three times, and the test result is recorded in an operation test recording table of the hanging basket 2. Then 1.2 times of construction rated load test can be stored in the hanging basket 2 for three times.

When the platform (hanging basket 2) slides to the middle pulling junction of the uppermost ropeway 1 and then moves towards the middle, the original pulley is replaced by another two pulleys, and the two replaced pulleys do not need to be connected (namely 2 pulleys are independent) so as to be convenient for the rotation of the pulleys; the sling 6 and the pulley are replaced simultaneously, and the specification is consistent with that before replacement. The hanging baskets 2 can be respectively hung on the cableway 1 at the two sides of the drag hook 19, so that the hanging baskets 2 can conveniently move along the cableway 1 to construct each construction area of the cableway 1.

Furthermore, the operation platform is a temporary platform and needs to be dismantled after construction is finished. Since the operation platform is mainly supported and fixed by the structural beams 3 in the application environment. Therefore, after the application of the operating platform is finished, the method further comprises the following steps: and (5) carrying out rechecking and acceptance inspection on the structural beam 3 in the application environment. To ensure that the operation platform does not affect the structural beam 3 in the application environment.

Further, the method for dismantling the operating platform after the application is completed comprises the following steps: the installation process is reversed, and the installation is firstly followed by disassembly, and then the installation is followed by disassembly. And finally detaching the safety rope.
