1. Materials and Structural Parameters
During long-term use, the cable reel of the loader is prone to faults due to frequent bending, mechanical wear, environmental corrosion, and other factors. The following is a complete guide to troubleshooting loader cable reel faults: Fault Types and Causes Mechanical Wear: Due to repeated bending, the outer sheath is prone to surface wear and scratches. The main causes include improper pulling during operation, non-standard installation, and collisions with sharp objects in the site environment.
Insulation aging: When exposed to high temperatures, ultraviolet rays, and chemical media for a long time, insulation materials gradually harden and crack, thereby reducing insulation performance. This is the result of both the material's own performance degradation and environmental factors.
Conductor breakage: Repeated bending may cause local fractures in the internal stranded copper cores due to fatigue, affecting the overall transmission performance of the cable. This is usually the result of long-term fatigue accumulation and local stress concentration.
Environmental corrosion: In acidic, alkaline, or oily environments, the cable's outer sheath and insulation layer may undergo chemical reactions, resulting in corrosion, discoloration, or even cracking. This not only reduces the cable's insulation performance but may also cause safety issues such as short circuits.
Inspection Methods Appearance Check: After each work cycle, a comprehensive inspection of the cable's appearance should be conducted, focusing on whether the outer sheath has scratches, cracks, peeling, or signs of aging, and checking for excessive wear or tearing, especially at vulnerable areas such as the reel entry and rail bends. At the same time, check whether the cable connections are secure and whether there are any signs of looseness or oxidation. Electrical Performance Testing: Use a multimeter to measure the conductor resistance and insulation resistance to ensure they are within the normal range, and perform a continuity test on the shield grounding. If the cable contains signal lines, test the signal integrity and noise interference levels to determine whether there are issues such as conductor breakage, short circuits, or poor insulation.
Operation Status Monitoring: Devices such as temperature sensors and stress sensors can be used to monitor the cable's operating status in real time. If abnormal temperatures or excessive bending are detected, on-site inspection should be carried out promptly to check for localized overheating, uneven stress, and other conditions.
Fault handling measures: Circuit break: After confirming that the wire is interrupted from start to end, if there is a local fracture, the insulation at the broken point can be removed, connected with crimp terminals, and the outer layer sealed with heat shrink tubing; If the fracture is severe, replace the conductor or the entire cable.
Short circuit fault: Confirm the location of the short circuit. If the damage is caused by insulation damage, repair the damaged insulation. If the damaged area is large or difficult to repair, relay the cable or replace the damaged section.
Poor contact fault: Clean the oil and oxide layer on the wire contact surface, apply waterproof conductive grease, and then re-tighten the wire connection points. If necessary, a metal waterproof junction box can be added.
Preventive maintenance measures: Standardized installation and operation: Ensure the cable is laid flat and winded evenly during installation to avoid mechanical damage caused by localized stress. Operators should handle the cable gently during use and avoid severe pulling and compression.
