Effective Electrical Equipment Maintenance Protocols for Optimal Crane Performance

In the realm of crane operations, the maintenance of electrical equipment stands as a pivotal task, ensuring not just the smooth functioning but also the safety of the entire system. Establishing a robust electrical maintenance system is paramount, with specific intervals structured around the crane's work duty and environmental conditions.

Daily Maintenance:

Every day, during shift handovers, crane drivers meticulously inspect and maintain the electrical components. This includes cleaning external surfaces, detecting heating issues in motor parts, inspecting bearings for oil leaks, and ensuring the tightness of wire joints. All observations of special conditions are diligently recorded.

Ten-Day (or Bi-Weekly) Maintenance:

Performed jointly by electricians and crane drivers, this maintenance involves cleaning internal components, observing wear in motor parts like brush carriers and slip rings, and checking for abnormal sounds during operations. Controllers and switch contacts are inspected and repaired as needed.

Annual Maintenance or Overhaul:

Conducted exclusively by experienced electricians, the annual maintenance or overhaul is a comprehensive process. It includes disassembling electrical equipment for thorough cleaning, examining support structures, cleaning motor rolling bearings, measuring gaps between stator and rotor, and replacing bearings if uneven wear is detected. Insulation resistance is measured, and necessary drying processes are carried out. All defects are rectified, and irreparable components are replaced, with the scope of this maintenance dictated by the actual wear and aging levels of the equipment.

Fire Safety Measures:

Crucial fire safety protocols are in place, including the use of dry fire extinguishers, primarily carbon tetrachloride extinguishers. In case of a fire outbreak, the immediate action involves cutting off the power supply. Emergency switches and knife switches on protecting panels are used for this purpose. Conductors catching fire require the knife switch on the feeding line to be cut off.

In the event of a crane catching fire, a meticulous cleaning, drying, and inspection process is mandatory for all electrical equipment and wiring. The crane can only be reinstated for operation after successful repairs and thorough quality checks.
