Concrete pump swing system spare parts include the hydraulic swing motor, reduction gearbox, slewing bearing, and integrated braking assembly. Hydraulic motor operating pressure typically ranges from 250 to 350 bar, with output torque between 8 and 65 kilonewton meters. The planetary gearbox provides reduction ratios from 1:25 to 1:120, and gear teeth are hardened to 58 to 62 HRC. The slewing bearing is manufactured with diameters from 600 to 2200 millimeters and axial clearance below 0.3 millimeters. The ring gear material is alloy steel with yield strength exceeding 700 megapascals. Sealing is achieved using oil seals resistant up to 90 degrees Celsius.

The swing assembly structure is designed based on contact stress and surface fatigue analysis to ensure service life beyond 10^6 cycles. Induction hardening of gear teeth is performed to a depth of 3 to 5 millimeters. Operating rotational speed is typically controlled between 0 and 2 revolutions per minute for precise boom positioning. Internal braking torque ranges from 3 to 12 kilonewton meters to stabilize the boom during توقف. Gear machining tolerances comply with ISO 8 accuracy class or better. Quality control includes torque testing, vibration analysis, and precise dimensional inspection of bearings and gearboxes.You can order and buy gear from Iran by contacting us through whatsaap and email.
