How to troubleshoot and perform routine inspections on the Foldable Shop Crane?

Foldable Shop Crane, as a foldable workshop lifting equipment, is widely used in various industrial production and maintenance occasions. To ensure its safe and efficient operation, troubleshooting and daily inspections are particularly important.

1. Daily inspection
Routine inspection is the basis for ensuring the normal operation of the Foldable Shop Crane. The following are the key points for daily inspection:
Appearance inspection: First, check the overall appearance of the crane, including whether the paint is peeling and rusted, whether the connections between components are loose, and whether there are cracks or deformations.
Electrical system inspection: Check whether the electrical circuits are intact, without damage or aging; whether the switches and buttons are flexible and reliable, and whether the indicator lights light up normally.
Hydraulic system inspection: For hydraulically driven cranes, check whether the oil level in the hydraulic tank is within the normal range, whether the hydraulic pipeline is leaking, and whether the hydraulic pump is running smoothly.
Safety device inspection: Check whether the overload limiter, height limiter, anti-decoupling device and other safety devices are intact and effective.
Inspection of pulleys and wire ropes: Check whether the pulleys rotate flexibly and have no jamming; whether the wire ropes are worn or broken, and whether they are firmly fixed.

2. Troubleshooting
When the Foldable Shop Crane fails, targeted troubleshooting should be carried out based on the failure symptoms. The following are some common faults and troubleshooting methods:
The crane cannot be raised or lowered: first check whether the power supply is normal and whether the electrical system is faulty; secondly, check whether the hydraulic pump and hydraulic motor are working normally and whether the hydraulic pipeline is blocked; finally, check whether the pulleys and wire ropes are blocked.
Abnormal crane lifting speed: This may be caused by a fault in the electrical system or hydraulic system. Check whether the speed regulating device in the electrical system is normal and whether the relief valve in the hydraulic system is improperly adjusted.
Unstable operation of the crane: It may be caused by unstable foundation, uneven track or insufficient tire pressure. The foundation and track conditions of the crane should be checked, and the tire pressure should be adjusted to the normal range.
Safety device failure: Failure of safety devices should be replaced or repaired in time. For example, overload limiter failure may be caused by sensor failure or circuit problems, which should be investigated and repaired one by one.

3. Precautions
When performing troubleshooting and daily inspections, you need to pay attention to the following points:
Safety first: During inspection and maintenance, be sure to ensure that the crane is in a safe condition to avoid accidents.
Follow the operating specifications: Strictly follow the operation manual and maintenance guide, and do not disassemble or replace parts at will.
Use professional tools: Use the appropriate tools and equipment to perform inspections and repairs to avoid damaging the crane or causing personal injury.
Record inspection and maintenance conditions: After each inspection and maintenance, the relevant conditions should be recorded in detail for future reference and analysis.
Through strict daily inspections and regular troubleshooting, the safe operation and extended service life of the Foldable Shop Crane can be effectively guaranteed. At the same time, it can also improve production efficiency, reduce maintenance costs, and create greater economic benefits for enterprises.
