This 320-ton crawler crane slewing ring adopts a mature optimized structural design, bringing outstanding performance advantages for heavy hoisting operations in complex working conditions.
Mature Three-Row Roller Structure with High Controllability: The simplified three-row cylindrical roller structure ensures excellent load-bearing performance, while greatly improving the controllability of product quality and performance during manufacturing and testing, guaranteeing consistent high performance for every delivered product.
Compact Dimensions with Ultra-High Load Capacity: The optimized structural design achieves a small overall footprint while retaining exceptional axial, radial, and overturning moment load capacity, perfectly adapting to the limited installation space of 320-ton crawler cranes without sacrificing load performance.
Extended Service Life for Long-Term Continuous Operation: High-strength bearing steel, precision heat treatment, and super-finished raceway surfaces effectively reduce contact stress and wear during operation, significantly extending the service life of the heavy lifting equipment slewing bearing and reducing equipment downtime and maintenance costs.
Wide Adaptability for Multi-Scene Applications: Beyond core crawler crane applications, the product’s universal structural design allows it to be adapted to a wide range of heavy rotational equipment, meeting the diverse needs of different industrial operation scenarios.
The 131.45.2500.10Z1 slewing bearing is originally designed for 320-ton heavy crawler cranes, with full compatibility for mainstream OEM 320-ton crawler crane models. Its excellent comprehensive performance also makes it widely applicable to other heavy lifting and rotational machinery, including truck cranes, port hoisting machinery, ship unloaders, stacker-reclaimers, and large-scale rotary platforms used in bridge construction, wind power installation, and petrochemical engineering projects.
To ensure stable operation and maximum service life of your crawler crane slewing ring, we have formulated standardized operation guidelines for industrial business clients:
Pre-installation: Verify the integrity of the slewing ring and accessories after delivery, check the flatness and rigidity of the mounting support, and remove all impurities and foreign matter from the mounting surface.
Installation: Use only specified high-strength bolts and matching washers, tighten bolts in a cross-symmetrical sequence with graded torque, and complete runout testing after installation to ensure rotational smoothness.
Operation: Strictly follow the equipment’s rated lifting capacity, avoid partial load and sudden start/stop operations during full rotation, and prohibit operation in extreme weather conditions beyond the design range.
Maintenance: Fill the raceway with specified lubricating grease before initial operation, perform regular lubrication according to the working frequency, conduct quarterly inspections of gear wear and bolt pre-tightening force, and complete a full disassembly inspection every 2 years for heavy-load continuous operation equipment.
We provide targeted customized solutions for industrial business clients, including lifting machinery manufacturers, national key project contractors, port operation groups, and professional equipment spare parts distributors. Our customization services cover gear profile modification, anti-corrosion and wear-resistant surface coating, material performance upgrading, and mounting structure adjustment to adapt to special working conditions such as marine, high-altitude, and low-temperature environments. For bulk procurement orders, we offer exclusive volume-based pricing, fixed production lead time commitments, full-process quality tracking, and one-stop technical support from design to after-sales, as well as flexible OEM production services to meet your brand and product matching needs.
Yes, in addition to 320-ton crawler cranes, this slewing ring is also compatible with truck cranes, port hoisting machinery, and other heavy rotational equipment, and we can provide targeted modifications to meet non-standard application needs.
Each slewing ring undergoes full dimensional inspection, raceway hardness testing, rotational resistance testing, and load simulation testing before delivery to ensure compliance with design and application requirements.
Yes, we provide remote installation guidance for all clients, and on-site technical support services can be arranged for bulk procurement and long-term cooperation clients according to actual needs.
