Product Detail

Zoomlion 1139800850 Roof Window Pneumatic Spring RH Bracket – Genuine Crane Cab Hardware

The Zoomlion 1139800850 Roof Window Pneumatic Spring RH Bracket is a genuine OEM replacement mounting component designed for the cab roof window system on Zoomlion cranes. This right-hand (RH) bracket serves as the fixed anchor point for the pneumatic spring (gas strut) that supports and assists in opening the roof window, ensuring smooth, one-handed operation and safe retention of the window in the open position.

As a critical piece of cab hardware, this bracket securely mounts the pneumatic spring to the cab roof structure, enabling proper operation of the roof window system that provides operators with enhanced visibility and ventilation during crane operations.

FeatureBenefit
Genuine OEM QualityFactory-original Zoomlion part ensures perfect fit and reliable performance
Right-Hand (RH) PositioningPrecision-engineered for the right side of the roof window system
Secure MountingProvides stable attachment point for pneumatic spring (gas strut)
Durable ConstructionIndustrial-grade materials withstand harsh construction environments
Direct ReplacementNo modifications required; straightforward installation
Essential System ComponentCritical for proper roof window operation and operator safety


Function & Role in Roof Window System

The pneumatic spring mounting bracket serves several critical functions:

  1. Secure Anchor Point: Fastens the pneumatic spring to the cab roof structure, providing a fixed base for the gas spring assembly 
  2. Proper Alignment: Ensures the gas spring is correctly positioned to support the roof window throughout its full range of motion
  3. Smooth Operation: Enables controlled, one-handed opening of the roof window
  4. Safety Retention: Maintains the window securely in the open position when engaged
  5. System Integrity: Prevents premature wear on the gas spring and window hinge mechanisms

In a typical gas spring installation, the bracket is installed with a ball stud that connects to the gas spring's end fitting, allowing for the pivoting motion required during window operation . This design provides both support and flexibility, ensuring the roof window can be opened and closed smoothly.

Compatibility & Applications

This pneumatic spring bracket (1139800850) is designed for the right-hand (RH) side of roof window systems on Zoomlion crane models equipped with roof windows, including:

  • QAY Series All-Terrain Cranes – QAY220 (featuring roof window with wiper and washer) 
  • ZTC Series Truck Cranes – Models with cab roof windows
  • ZAT Series All-Terrain Cranes
  • QY Series Truck Cranes – QY25V531, QY16V, QY20V
