High Pressure Tower Crane Rotary Joint for Dust Removal

Description

Tower Crane Rotary Joint: Product Details

The Tower Crane Rotary Joint for Dust Removal is a high-performance rotary union designed specifically for construction environments where dust control and environmental protection are critical. Engineered for seamless rotation and reliable fluid transfer, this rotary joint allows high-pressure water or air to flow continuously between the stationary supply line and the rotating boom of a tower crane.

In modern construction projects, especially those involving concrete mixing, demolition, or material handling, effective dust suppression is essential. The crane rotary joint serves as the core connection between the dust removal spray system and the crane arm, ensuring uninterrupted operation and consistent spraying performance.

Key Features

High-Precision Sealing Technology

Equipped with advanced mechanical seals that prevent leakage even under high-pressure conditions, ensuring stable operation and long service life.

Durable Stainless Steel Construction

The main housing is made from corrosion-resistant stainless steel, providing excellent durability against water, abrasive dust, and harsh weather environments.

360° Continuous Rotation

The rotary union allows the crane’s spray arm to rotate freely, maintaining constant fluid transfer without twisting or tangling hoses.

Wide Compatibility

Available in multiple thread sizes and passage configurations to suit different tower crane models and custom dust removal systems.

Low Maintenance Design

Internal bearings are self-lubricating and sealed to protect against wear, minimizing downtime and extending service intervals.

How it Works

The Tower Crane Rotary Joint for Dust Removal connects the water supply line to the rotating crane boom. As the boom moves, the rotary joint maintains a sealed connection, allowing pressurized water or air to pass through continuously.
This flow powers the dust suppression nozzles, which evenly spray a fine mist over the construction area, trapping airborne particles and reducing pollution.

This continuous operation eliminates the need for manual hose adjustment, increases safety, and enhances working conditions on-site.

Advantages of Using a Rotary Joint in Dust Removal Systems

1. Consistent Spray Coverage – Maintains steady water flow during rotation.

2. Improved Worksite Visibility – Reduces suspended dust, ensuring better visibility for crane operators.

3. Long-Term Reliability – Sealed bearings and high-quality seals ensure years of trouble-free service.

4. Reduced Maintenance Costs – No need for frequent disassembly or lubrication.

5. Environmentally Friendly Operation – Lowers airborne particulate emissions, improving urban air quality.

Applications

The rotary joint can be integrated into various dust control systems across multiple industries:

• Construction Sites – For crane-mounted spray arms in high-rise building projects.

• Demolition Work – Reduces airborne dust generated by debris.

• Mining and Quarrying – Used to suppress dust around conveyors and crushers.

• Material Loading Yards – Maintains clear air during sand or cement handling.

• Environmental Protection Projects – Supports municipal dust suppression vehicles and crane-mounted sprayers.
