Summer Maintenance Tips for Spider Cranes

To ensure the optimal performance and longevity of pavoučí jeřáby during the hot and humid summer months, it’s crucial to implement a comprehensive maintenance strategy. The following guidelines are designed to help operators and maintenance teams keep spider cranes in top condition, minimizing downtime and maximizing efficiency.​

Summer Maintenance Tips for Spider Cranes

1.Cooling System Maintenance

-Regular Cleaning: Before the onset of summer, thoroughly clean the cooling system components, including radiators and fans, to remove dust and debris that can impede airflow.​

-Inspect and Tighten Connections: Check all hoses and clamps for signs of wear or looseness, ensuring there are no leaks or weak points in the system.​

2.Hydraulic System Care

-Filter Replacement: Replace hydraulic oil filters regularly. Specifically, change the return oil filter every 500 operating hours and the suction oil filter every 1,000 hours to maintain hydraulic fluid cleanliness.​

-Heat Exchanger Cleaning: Depending on usage frequency, clean the hydraulic system’s heat exchanger every six months to ensure efficient heat dissipation.​

3.Structural Integrity Checks

-Daily Inspections: Conduct daily checks of the crane’s structural components, including the boom and outriggers, for signs of cracks, corrosion, or other damage.​

-Rust Prevention: Promptly address any rust spots by cleaning and repainting affected areas to prevent further corrosion, especially during the rainy season.​

4.Lubrication Practices

-Seasonal Oil Changes: Switch to summer-grade engine oil and lubricants before the hot season begins to ensure optimal viscosity and protection under high temperatures.​

-Leak Detection: Perform monthly checks for oil leaks, paying close attention to fuel lines and hydraulic connections.​

5.Electrical System Maintenance

-Battery Care: Reduce charging currents during summer to prevent overheating. Ensure all electrical connections are secure and free from corrosion.​

-Wiring Inspection: Replace any aging or damaged wires and verify that all fuses meet the required safety standards.​

-Fire Safety: Equip the crane with a fire extinguisher as a precautionary measure.​

5.Hose and Radiator Checks

Hose Inspection: Before each use, examine radiator hoses for signs of wear, cracks, or leaks. Replace any compromised hoses immediately to prevent engine overheating.​

7.Monitoring Operating Temperatures

Temperature Gauge Monitoring: Keep an eye on the water temperature gauge during operations. If temperatures exceed 90℃, stop the pavoučí jeřáb in a shaded area and allow the engine to idle until it cools down to normal levels.​

8.Proper Storage

-Shaded Parking: Whenever possible, park the crane in shaded areas to protect it from direct sunlight, which can cause overheating and damage to components.​

-Use of Covers: If shaded parking isn’t available, use light-colored, waterproof covers to shield the crane from sun exposure.​

Supplying SS3.0 and SS5.0 Spider Cranes to a Brazilian Client

In January 2024, we initiated contact with a prominent Brazilian distributor specializing in lifting equipment. The client, previously an exclusive agent for Maeda spider cranes in Brazil, was exploring alternative suppliers to diversify their offerings.​

Client Requirements: SS3.0 and SS5.0 spider cranes.​

Customization:

-Power System: Equipped with both electric motors and Yanmar diesel engines to provide versatile power options.​

-Control System: Integrated with a cyber remote control system featuring proportional control valves for precise operation.​

-Safety Features: Included torque limiters and indicators, three-wrap winch alarms, hook overwind alarms, and outrigger sensors to enhance operational safety.​

-Boom Configuration: Two-section single extension booms for flexible lifting capabilities.​

-Voltage Specification: Configured for 220V, 60Hz, 3-phase power supply to match local standards.​

-Hydraulic Fly Jib: A hydraulic fly jib was added to the 5-ton spider crane to extend its reach and versatility.​

-Color Customization: Both cranes were painted in a custom green color matching the client’s previous order.​

Production and Delivery: The client emphasized the importance of completing production within 20 working days to allow for on-site testing.​

Zajištění kvality: Given the client’s background and potential for future orders, we ensured meticulous attention to detail in every aspect of the cranes’ manufacturing and assembly processes.
