Wellhead Big Bend Pulley + 3φ2.5cm Nylon Pulleys Seamless Welding + Dust-Proof Bearings Ground Cable Corner Guidance

I. Product Overview

-
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. -
Main Structure: -
Key Dimensions (based on measured markings in the image):
-
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.

-
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.
-
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.
-
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.
-
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:

-
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.

-
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.
