Key points for summer maintenance of KB Spider cranes: Long-lasting protection for high-temperature construction

High temperatures, heavy rain, and dust during the peak of summer can easily cause engine overheating, hydraulic oil deterioration, and electrical system dampness, leading to malfunctions. Proper seasonal maintenance of the KB spider crane can reduce downtime and extend the machine's lifespan. This involves standardized maintenance of four main components: power, hydraulics, travel, and electrical control.

The power system is paramount for summer maintenance. Regularly clean the air filter; replace it promptly if severely clogged. Check the coolant level and radiator fan to prevent overheating due to insufficient coolant. Clean dust from the motor surface to prevent dust accumulation from hindering heat dissipation and causing coil overheating. Regularly add lubricating grease to the emergency manual pump to prevent the grease from drying out and jamming at high temperatures, ensuring normal operation during power outages.

High-temperature maintenance of the hydraulic system is also crucial. High temperatures accelerate the aging and deterioration of hydraulic oil. Regularly check the oil color; change the oil immediately if it turns white or emulsifies. Inspect all hydraulic lines and oil seals; high temperatures can cause seals to age and leak oil. Replace any leaking seals immediately. Wipe and clean the piston rods of the outrigger hydraulic cylinders to prevent mud and sand from scratching the plating and causing oil leaks.

Pay special attention to dust and water protection for the tracks and walking system. In rainy and muddy summers, promptly clean mud and gravel from the gaps in the rubber tracks after operation to prevent hard objects from damaging the track surface; check the outrigger pins and wheel bearings, and replenish with high-temperature special grease to prevent dry friction wear of parts due to lack of lubrication. Wipe dry any water accumulated on the chassis after rain to prevent rust on metal parts.

Maintain moisture-proof and heat-resistant electrical control and safety components. Protect remote controls and the main control panel of the vehicle from sun and rain during outdoor operations. Wipe dry wiring connectors after rain to prevent short circuits. Pay special attention to verifying the tilt anti-rollover system and torque limiter; high temperatures can cause sensor values ​​to deviate, so calibrate parameters to ensure timely alarm and machine locking when tilt exceeds the limit.

Develop good daily usage habits: avoid prolonged continuous operation in the extreme midday heat, and stop intermittently to allow for cooling; when not in use for extended periods, store in a dry, well-ventilated warehouse and cover with rainproof and sunproof cloth. By implementing standardized summer maintenance, the KOBIT spider crane can reliably cope with high-temperature and rainy season construction, effectively reducing maintenance costs and ensuring efficient project progress.
