360 Degree Tower Crane Spray Universal Rotary Joint

Description

Product details

The 360 Degree Tower Crane Spray Universal Rotary Joint is an essential component in modern construction site dust suppression systems. Designed to rotate freely with high-pressure water flow, this multi-directional swivel joint enables consistent and even spraying coverage from the tip of the tower crane jib, ensuring maximum reach and flexibility. It is a precision-engineered rotary union designed specifically for tower crane spraying systems, offering full 360-degree rotation to enable continuous, uninterrupted fluid transfer. Crafted from high-quality materials such as brass or stainless steel, this rotary joint supports high-pressure water, hydraulic oil, air, and other media, ensuring reliable performance in harsh construction environments.

This joint plays a critical role in tower crane spray systems, where dust control, cooling, and environmental compliance are vital. Compatible with various pipe sizes and pressures, it connects the stationary pipework to rotating nozzles and spray heads, allowing full 360-degree rotation without leakage or flow interruption.

Key Features

Full-Coverage Spray Radius – Matches Tower Crane Rotation

Our rotary joint enables a 360-degree continuous spray coverage, fully synchronized with the rotational radius of the tower crane.
As the crane rotates during material lifting or movement, the water spray or mist follows the same arc, ensuring no blind spots.
This wide-area atomization capability makes it ideal for large-scale construction zones, high-rise projects, and foundation works.

Effective Dust Suppression & Pollution Control

Equipped with high-pressure nozzles and a leak-free swivel design, this joint forms a fine mist that effectively traps airborne dust particles.
It helps reduce dust concentration, construction haze, and airborne pollutants, significantly improving onsite air quality and visibility.
By keeping suspended particles down, it also minimizes respiratory hazards, controls PM2.5/PM10, and contributes to environmental regulation compliance.

Ground Cooling & Concrete Moisture Retention

In hot summer or dry climates, the rotary joint’s mist spray assists in cooling the work area and lowering surface temperatures.
It prevents overheating of materials and machinery and provides evaporative cooling to improve worker comfort and operational safety.
Additionally, it helps keep poured concrete moist, preventing premature surface cracking, improving curing quality, and extending the structure’s lifespan.

Constitute

1. System Composition

The high-altitude spray dust removal system consists of:
🔄 Special rotary universal joint (for tower cranes)
🔩 Support brackets
🚿 Water pipes & adjustable nozzles
🧵 Loose joints & tees
🧹 Water filters
This combination ensures precise spray direction, efficient dust suppression, and easy maintenance.

💧 2. Water Supply Options

Two flexible intake methods are available:
🌐 Municipal pipeline connection
Connect directly to the city water supply
♻️ Recycling system integration
Use recovered water with a pressurized pump to deliver to the tower crane’s spray system.

Piping setup

1. Sprinkler Layout Planning

Sprinkler heads are installed every 2–3 meters along the rotating arm.
Water pump, piping, and universal joint types are selected based on:
💧 Required water flow
⚙️ Pressure per sprinkler head
The layout must adapt to on-site conditions and application needs.

2. System Integration & Support Structure

The pipeline and spray universal joint are installed in line with the tower crane’s rotating wheel core.
Ensures the entire system is coaxial and concentric for reliable operation.
Welding is prohibited on standard tower crane parts.

3. Fixed Support Design

A special rotary universal joint uses two fixed supports.
Supports are secured via screw buckles, ensuring modularity and maintenance access.
The pipe support is also screw-connected directly to the crane for seamless integration.

Tower Crane Spray System – Important Precautions

🔍 1. Routine Inspection

Regularly check if the pipe support and universal joint bracket are:
🧰 Shifted or misaligned
🔩 Loose or unfastened
Ensure structural safety and system stability.

🚰 2. Long-Distance Pipe Layout

When the main spray pipe exceeds 200 meters,
It is recommended to:
🔄 Install booster pumps at regular intervals
✅ Maintain consistent water pressure and spray efficiency

❄️ 3. Winter Protection (Northern Regions)

To prevent pipe freezing:
🌡️ Bury main pipelines ≥ 1 meter deep
🧣 Apply thermal insulation or heating measures

📌 Best Practices

Perform seasonal maintenance checks.
Follow regional climate guidelines
Use quality fasteners and insulation materials
