Conductive Slip Ring: High Reliability & Long Lifespan for Stable Power & Signal in Heavy-Duty Grabs & Buckets

1.Introduction

For heavy-duty equipment like orange peel grabs, clamshell grabs, diaphragm wall grabs, and dragline buckets, one big challenge is keeping power and signals flowing non-stop when parts rotate. That’s where the JiuJiang In-giant DHK120-12-002 Conductive Slip Ring comes in—it’s built to solve this exact problem. This slip ring acts as a “bridge” between the rotating and fixed parts of your machinery, making sure power gets to motors and control signals stay steady. Unlike cheap, generic slip rings that break down easily under tough work conditions, the conductive Slip Ring is tough enough to handle dust, vibration, and temperature changes. For you, that means less time fixing equipment and more time getting work done—whether you’re moving bulk materials at a mine or building deep foundations for a skyscraper. It’s not just a part; it’s a way to keep your heavy machinery running smoothly.

2.Key Technical Details

You don’t need to be an engineer to understand why the our products works for your grabs and buckets—here’s what matters most, in simple terms:

(1) Channels & Power:

• 12 total channels, split into two groups
• 8 power channels: Each handles 10A (24VDC) – perfect for powering grab motors or dragline bucket lifts.
• 4 CANbus channels: Also 10A (24VDC) – ensures control signals (like “close the grab”) send clearly, so your equipment responds right when you need it.    

(2)Voltage Match: Works with 0~24VDC, which fits most construction and mining machinery—no extra adapters needed.

(3)Safety First:

• Insulation resistance of 250MΩ (250VDC): Prevents electrical leaks, keeping your team safe.
• Dielectric strength: Handles 250VAC (50Hz) for 60 seconds (less than 1mA leakage): Won’t fail from small voltage spikes.

(4)Smooth Performance: Dynamic resistance stays under 10mΩ—almost no power loss, so grabs move consistently all shift.

(5)Tough Against Conditions:

• Speed: 0~200rpm – matches how fast your equipment’s parts rotate.
• Temperature: -20°C to +80°C – works in cold winters or hot mining sites.
• Humidity: <70% – no rust or corrosion in damp areas.
• Dust Protection: IP51 rating – keeps mine dust out, extending life.

(6)Built to Last:

Body: Aluminium alloy (light but strong, handles vibration).

Contacts: Precious metals (don’t wear out fast, less maintenance).

 (7)Easy Installation: Rotor and stator leads are 5000mm long—fits most machinery layouts.

3.Where It Works Best

This slip ring is made for four key heavy-duty tools—here’s how it helps:

• • Orange Peel Grabs: These multi-jaw grabs need power for jaws and clear signals to grip materials (coal, iron ore). The 8 power/4 CANbus channels keep jaws in sync, and IP51 stops dust from jamming parts.
• • Clamshell Grabs: Used for wet materials (sand, gravel), they face moisture and shaking. The slip ring’s humidity resistance and strong body prevent rust, so it works in mud.
• • Diaphragm Wall Grabs: For deep foundations (bridges, skyscrapers), they operate underground. The wide temperature range handles underground heat/cold, and strong insulation avoids electrical risks.
• • Dragline Buckets: Large mining buckets need steady power to lift heavy loads. The 10A per channel delivers enough power, and precious metal contacts hold up to frequent rotation—no downtime mid-shift.

4. How to Choose

Picking the right slip ring is easy—follow these 3 steps to check if the DHK120-12-002 fits:

1.Power & Signals: Do you need 8 power channels (for motors) and 4 CANbus channels (for controls)? If your equipment uses 24VDC (most do), this works.

2.Work Environment: Is your site’s temperature between -20°C and +80°C? Is dust a problem (not heavy rain)? IP51 and humidity resistance will handle it. Need more protection                                        (e.g., rain), We can customize.

3.Installation: The 5000mm leads fit most machinery, but if you need shorter/longer wires, we can adjust.
