1. Power and Control System Failure
Indicator light off/no response: Check the power jack for poor contact and replace any blown fuses (e.g., 5A).
Abnormal control signal: Check for aging circuitry or sensor failure. Prefer IP68-rated waterproof sensors (which reduce the failure rate by 52%).
2. Hydraulic System Problem
Unable to lift:
Motor reverses: Swap the power phases (e.g., any two phases L1/L2/L3).
Hydraulic oil contamination: Filter or replace with N32 low-freezing hydraulic oil and thoroughly clean the oil circuit (including the check valve, cylinder, etc.).
Frozen oil circuit: In cold regions, preheat the engine and replace with antifreeze hydraulic oil.
Automatic lowering:
The hand pump unloading valve is not closed: Retighten the valve until it is sealed.
Support valve wear: Replace the valve body or clean any foreign matter inside the valve. 3. Mechanical Structure Jam
Lift Jam:
Lubricate bearings, hinges, and other moving parts (lithium-based grease is recommended).
Check the scissor lifts or roller grooves for foreign objects (such as gravel or metal shavings).
Tower Tilt: Calibrate the cable tension (using a tension gauge) and tighten the ground spikes or support legs.
4. Intelligent System Optimization
Use an intelligent pressure regulation system (improving lifting speed stability by 61%) or dynamic flow valve technology (optimizing the response speed standard deviation to ±0.4s).
Use the IoT to monitor parameters such as oil pressure and motor load to provide early warning of failures (such as the Zhuo Ao Shi Peng cloud management system).
Safety Operation Recommendations: Disconnect power during maintenance and avoid working with live power.
When working at height, wear a safety belt and use a fall arrest device.
Do not use during thunderstorms and ensure the lightning protection grounding resistance is ≤10 ohms.
