Wellhead Big Bend Product Specifications

I. Product Overview

II. Core Structure and Parameters

1. Overall Appearance

   
   

• Bottom Length (Trapezoid Base): 67 cm (accommodates long-distance cable turns).

  
  

• Height (Trapezoid Vertical Height): 50 cm (meets standard corner height requirements).

  
  

• Frame Width (Distance Between Trapezoid Sides): 22 cm (ensures stability and installation compatibility).

  
  

• Single Pulley Diameter: 2.5 cm (precisely fits most conventional cable diameters).

  
  

• Center-to-Center Spacing Between Pulleys: 34 cm (ensures smooth cable transition between pulleys).

  
  

• Bracket: Red metal trapezoidal frame (stamped from high-strength reinforced iron plate, providing robust support).

  
  

• Pulleys: Three yellow cylindrical nylon pulleys (uniform diameter, smooth surface to minimize cable friction).

  
  

• Design Form: Trapezoidal frame structure (resembling a ladder-like shape), with three pulleys vertically aligned in a straight line at the center of the frame, tailored for 90° or wide-angle ground cable turns.

2. Key Components

   
   

• Material: Reinforced iron plate with internal ribs (stamped and formed).

  
  

• Thickness: Measured at 5.0 mm (manufactured to a standard 5mm thick, ensuring high strength and safety).

  
  

• Material: Premium yellow nylon (engineering plastic, wear-resistant and anti-aging).

  
  

• Features: Smooth surface protects cable sheaths during rotation, significantly reducing friction damage risks; lightweight design minimizes load on the frame while offering excellent wear resistance and quiet operation.

  
  

• Nylon Pulleys:

  
  

• Iron Plate Bracket:

  
  

• Bearing Design: Each pulley incorporates an integrated dust-proof bearing (sealed structure to block dust/debris ingress), ensuring smooth rotation.

  
  

• Welding Process: All critical connection points of the bracket (e.g., trapezoidal frame joints, pulley shaft mounting points) utilize seamless welding technology, resulting in smooth, burr-free, and high-strength welds.

  
  

III. Four Core Advantages

1. Reinforced Thickness for Superior Load-Bearing

   
   

• Craftsmanship: The bracket is stamped from 5mm-thick reinforced iron plate with internal vertical/horizontal ribs, creating a one-piece structure with enhanced rigidity (not thin ordinary plates).

  
  

• Effect: Supports higher loads (suitable for simultaneous multi-cable turns), resists deformation over long-term use, and ensures safety and reliability for industrial heavy-duty applications.

  
  

2. Seamless Welding for Exceptional Durability

   
   

• Craftsmanship: All edges and critical joints of the trapezoidal frame (e.g., pulley shaft mounting brackets) are joined using seamless welding technology, producing uniform, flawless welds with superior bonding strength.

  
  

• Effect: Delivers outstanding structural integrity—resistant to cracking even under repeated use or external impacts (e.g., cable traction vibrations)—significantly extending the product’s lifespan and reducing maintenance needs.

  
  

3. Dust-Proof Bearings for Smooth, Effortless Operation

   
   

• Design: Each nylon pulley houses an integrated high-precision dust-proof bearing (sealed to prevent dust/debris entry).

  
  

• Effect: Minimizes rotational friction, reducing effort required for both manual and mechanical cable traction (saves energy). Also lowers heat generation and abnormal wear, ensuring smoother and more stable performance.

  
  

4. Premium Nylon Pulleys: Quiet, Durable, and Lightweight

   
   

• Wear Resistance: Moderate surface hardness prevents abrasion during prolonged cable contact, reducing replacement frequency and protecting cable integrity.

  
  

• Quiet Operation: Noise level below 40 dB during rotation (near ambient background sound), suitable for noise-sensitive indoor or laboratory environments.

  
  

• Lightweight: Significantly lighter than metal pulleys, reducing pressure on the bracket mounting points while maintaining sufficient strength to support cable weight.

  
  

• Material: The pulley wheels are made of high-quality yellow nylon (high-performance engineering plastic with excellent weather and fatigue resistance).

  
  

• Features:

  
  

IV. Applicable Scenarios

• Power Engineering: Guiding ground cables at turns to avoid sheath damage or stress concentration caused by sharp angles.

  
  

• Telecommunications Construction: Ensuring smooth transitions for fiber optic/communication cables at path bends, preserving signal transmission performance.

  
  

• Engineering Installation: Managing ground cable layouts for large equipment or pipelines, ensuring alignment with design specifications.

  
  

• Construction Sites: Temporary or permanent cable routing where precise corner angles are required.

  
  

V. Installation and Maintenance Tips

• Installation: Secure the bracket to flat ground, walls, or equipment supports using bolts/screws inserted through pre-drilled holes (verify actual hole locations on the product). Ensure the trapezoidal frame is tightly mounted to prevent loosening.

  
  

• Maintenance: Regularly inspect welding areas for rust or cracks (especially in humid environments, apply anti-rust treatment). Clean nylon pulley surfaces with a neutral detergent if contaminated with oil/dust (avoid strong acids/alkalis to prevent material degradation). Check bearing flexibility periodically; add a small amount of cable-specific lubricant if needed.
