Product Description
Counter weight roller
Counter Weight Roller is a key load-bearing and guiding component for tower crane counterweight system. Mounted on the counterweight frame, it rolls along the jib’s rear track to enable smooth horizontal movement of the counterweight, balancing the crane’s load moment during
trolley traversing. Made of forged alloy steel with precision bearings and heavy-duty sealing, it ensures stable, low-friction travel under high loads in harsh construction conditions.
Key Features
High Load Capacity: Forged steel wheel with hardened tread (HRC 45–55), supports heavy counterweight loads with high radial & axial strength.
Smooth & Low-Noise Operation: Precision sealed bearings reduce friction; minimal vibration and noise during traversing.
Wear & Impact Resistant: Heat-treated surface, anti-crack design, withstands shock loads and long-term frequent use.
Excellent Sealing: Multi-lip labyrinth seals prevent dust, water and debris; extends bearing life, low maintenance.
Easy Installation: Standardized dimensions, bolt-on mounting, interchangeable for most crane models.
Applications
Hammerhead, Flat-Top, Luffing Jib Tower Cranes: Core part for moving counterweight to balance load moment.
All Capacity Ranges: Used on small to large cranes (QTZ40 to 7030, 7050 series).
Construction Sites: High-rise buildings, bridges, infrastructure, industrial plants.
Aftermarket & Maintenance: Replacement part for Zoomlion, Sany, Potain, Terex, XCMG and other brands.
Heavy-Duty Lifting: Ensures safe and stable operation under frequent trolley movement and dynamic loads.
