AI Technical Summary
Tower crane wire ropes are prone to fatigue failure due to repeated bending and stretching during long-term high-intensity use, which can lead to sudden breakage.
A tower crane wire rope maintenance mechanism is adopted, which uses a low-pressure spray system driven by a micro water pump and a servo motor to lubricate, prevent rust, and clean the surface of the wire rope. Combined with auxiliary devices, it cleans the debris inside the water tank to prevent corrosion and jamming.
By uniformly spraying liquid through low-pressure spray nozzles, liquid waste and environmental pollution are reduced, the life of steel wire ropes is extended, breakage is prevented, and safety in use is improved.
