Maintenance Precautions for Aerial Work Platform Truck(3)
Release time:
2026-02-11
Data source:
Maintenance precautions for aerial work platforms mainly include daily maintenance and monthly upkeep.
3. The main reasons for the breakage of the wire rope of the aerial work platform vehicle include the following aspects.
✅① Overload and Improper Use
Overload: The tension on the wire rope exceeds its rated load capacity, leading to breakage. This may be due to operators not following safe operating procedures, being unaware of the weight of the load being lifted, blindly lifting, or design or manufacturing defects in the equipment itself, such as the lifting limit position limiter not being installed or malfunctioning, causing the hook to continue rising until the lifting wire rope is pulled down.
✅② Improper Use
This includes frequent overloading, incorrect operating methods (exceeding the working limits), excessive usage frequency without proper maintenance and inspection, etc., all of which can lead to fatigue damage and eventual breakage of the wire rope.
✅③ Material and Manufacturing Defects
Material Issues: The wire rope core material is too soft or lacks quality assurance, resulting in insufficient tensile strength and a high risk of breakage.
Manufacturing Defects: Such as rust or damage to pulleys, or wear between the wire rope and pulleys, these can accelerate wire rope damage.
✅④ Environmental Factors
Harsh environments such as high temperature, humidity, dust, and corrosion can accelerate the aging and strength reduction of wire ropes, leading to breakage.
✅⑤ Insufficient Maintenance and Inspection
Improper maintenance, such as improper upkeep of electrical components, aging and disrepair, or malfunctioning or slow-moving height limiters, can cause overwinding and rope breakage. Insufficient inspection, such as failure to promptly detect and replace damaged parts (e.g., regular maintenance and replacement of pulleys) and failure to adjust wire rope tension, can all lead to wire rope breakage during use.
In summary, the causes of wire rope breakage in aerial work platforms are multifaceted, including improper operation (overloading, exceeding the working radius), material defects, environmental influences, and insufficient maintenance and inspection. To prevent wire rope breakage, it is necessary to address these aspects by strengthening operator training, improving material quality, improving the operating environment, and conducting regular maintenance and inspections.
