Product Description

The Suspension Cylinder (Part No. 00767908401100003) is a genuine OEM spare part engineered by Zoomlion Heavy Industry for its leading mobile crane and all-terrain crane chassis. Designed as a critical component of the hydropneumatic suspension mechanism, this cylinder plays an essential role in supporting the vehicle frame, absorbing road shocks, and enabling active chassis leveling to ensure stability and safety during travel and lifting operations .

Key Features & Technical Functionality

1. Advanced Hydropneumatic Suspension Integration
This suspension cylinder operates as part of a sophisticated hydropneumatic system. It uses hydraulic oil and an accumulator (filled with an inert gas like nitrogen) as an elastic medium to absorb vertical axle loads and road impacts. This design converts kinetic energy into hydraulic pressure, providing superior damping, vibration absorption, and ride comfort, significantly improving the vehicle's smoothness on rough terrain .

2. Active Chassis Leveling Capability
A core function of this suspension cylinder is to support the crane's automatic frame leveling system . By extending or retracting based on signals from the vehicle body inclination angle sensor, the cylinder adjusts the chassis height to maintain a horizontal attitude. This capability is vital for preventing rollover accidents on transverse slopes or uneven ground, ensuring the crane body remains level for safe operation.

3. Rigid-Flexible State Switching
The suspension cylinder allows the operator to switch between a flexible (elastic) state for road travel to absorb shocks, and a rigid (locked) state for lifting or tire-supported auxiliary operations. Locking the cylinder increases structural rigidity and stability, ensuring safety during heavy lifting tasks .

4. Precise Control & Durability
Built to Zoomlion’s strict manufacturing standards, this cylinder features high-quality seals and robust materials to withstand extreme working pressures and harsh environmental conditions. It is designed for long service life and reliable performance, reducing maintenance downtime.
