Technical Field
[0001] This utility model relates to the field of hoisting equipment, and in particular to a cable and wire rope shaft hoisting device. Background Technology
[0002] Cables and wire ropes are core basic materials widely used in industries such as industry, construction, transportation, mining, and marine engineering. Cables are usually made of multiple strands of metal wires or fiber materials twisted together, and have good flexibility and tensile strength. They are widely used in power transmission, communication lines, lifting equipment, and other fields. Wire ropes are made of multiple strands of steel wires twisted together, and have extremely high tensile strength and wear resistance. They are mainly used in hoisting, traction, lifting, mooring and other occasions that require bearing large loads.
[0003] However, existing methods for hoisting cables and wire rope spools mostly involve manually binding them with straps before lifting them with a crane or forklift. This method is cumbersome and has a high risk factor. If the straps break, it can easily injure the construction workers. Moreover, it is inconvenient to operate. Therefore, those skilled in the art have provided a cable and wire rope spool hoisting device to solve the problems mentioned in the background art. Utility Model Content
