Zoomlion SJ53B01-01625 1139802242 Pneumatic Stay Assy – Genuine Hydro-pneumatic Suspension Component
Product Overview
The Zoomlion SJ53B01-01625 Pneumatic Stay Assy (Part No.: 1139802242) is a genuine OEM replacement component engineered for the hydro-pneumatic suspension system found on Zoomlion all-terrain and truck cranes. This pneumatic stay assembly serves as a critical element in the axle suspension and locking mechanism, ensuring stable chassis performance, effective shock absorption, and safe road driving characteristics for heavy-duty lifting equipment.
Technical Background
This pneumatic stay assembly is part of Zoomlion's advanced hydro-pneumatic suspension system, which has been widely adopted across the company's crane product lines. Zoomlion has secured multiple patents in this technology area, including recent innovations in hydro-pneumatic suspension hydraulic systems (Patent No. CN116039320B), featuring integrated main valves that reduce component count, save installation space, and simplify hydraulic circuits for easier manufacturing.
According to Zoomlion's official product documentation, models such as the ZAT1200V753Z all-terrain crane feature hydro-pneumatic suspension installed across all four axles, delivering superior shock absorption and allowing suspension lift or lowering for enhanced passing capability and driving comfort. The ZTC series truck cranes utilize this system specifically on Axles 1 and 2, with features including automatic level control and hydraulic locking functionality.
