Safety requirements for ropeway transport

Aerial ropeways are a special form of Wire Rope transport. It uses a wire rope erected in the air as a guide rail for trucks, while a truck uses a wire rope to haul cargo. According to the action mode of the traction wire rope, the aerial ropeway can be divided into a circulating aerial ropeway (the continuous action of the traction wire rope for the infinite traction) and the reciprocating aerial ropeway (the traction wire rope is used for the reciprocating action of the extreme traction). According to the number of wire ropes that make up the ropeway, it can be divided into multiple clues (composed of three or four wire ropes for passenger ropeways), double clues (with load cables and traction cables) and single clues (only one cable, it It is both a carrying cable and a traction cable). The aerial ropeway has the advantages of strong adaptability to natural terrain, low climate impact, simple loading and unloading facilities, low energy consumption and easy manufacture. Therefore, it plays a great role in the transportation of mines in China, especially in mountainous mines. There are security ropeway of the following requirements: (1) cableway line through the plant, residential areas, when railways and roads, should take security measures; (2) when the cableway wire and power and communication lines cross, should take safety measures (3) The line and sleeve of the load-bearing cable shall be inspected regularly after being put into transport; (4) The working brake and accident braking device must be set at the same time. If one of the faults occurs, the operation should be stopped; (5) The load-bearing cable is frequently checked. It is confirmed that within the length of 10 meters, the total number of external steel wire breaks is 35%, or it should be replaced when there is severe deformation; (6) When one of the following conditions occurs, the traction cable should be partially or completely replaced; If the number is more than 3, or the number of broken wires reaches 8 or more, the rope strands can be replaced. 2 When there are more than three strands in a section of steel rope that need to be replaced, the steel rope should be replaced completely; 3 When the diameter is reduced by 10% The entire wire rope should be replaced. (7) The length of the joint of the traction shall not be less than 1000 times its diameter, and the diameter increase shall not exceed 10%; (8) The center line of the line bracket shall be regularly corrected, and the line bracket is found to be severely corroded, cracked, loose, and skewed. Deformation and other conditions must be dealt with in a timely manner; (9) Rotary equipment in the station less than 2 meters above the ground, safety guards or safety fences should be installed, and station buildings above 0.6 meters should be installed. Or shoulder pads; (10) When there is a strong wind of 8 or more, stop running and take the lifting head back into the station.
