SHDNZ916 Helicopter Stringing Blocks are designed for overhead transmission line construction and helicopter-assisted conductor stringing. With a 916mm large diameter nylon sheave, 50kN rated load, and single sheave structure, this cable pulling block is suitable for ACSR700-800 conductors. The nylon sheave helps reduce conductor wear during pulling, while the large wheel diameter helps reduce bending stress for safer and smoother stringing work.
During helicopter stringing and overhead line installation, contractors often face:
These issues are mainly caused by:
The SHDNZ916 Helicopter Stringing Block solves these problems by:
| Parameter | Value | Engineering Meaning |
|---|---|---|
| Model | SHDNZ916 | Helicopter stringing block model |
| Sheave Diameter | 916 mm | Reduces conductor bending stress |
| Rated Load | 50 kN | Suitable for heavy-duty pulling work |
| Number of Sheaves | 1 Sheave | For single conductor stringing |
| Suitable Conductor | ACSR700-800 | Suitable for large overhead conductors |
| Sheave Material | Nylon | Reduces cable wear and friction |
| Weight | 51 kg | Strong structure for field use |
| Application | Transmission Line Installation | Used for overhead power line projects |
The stringing block guides the conductor through the rotating nylon sheave during pulling or helicopter-assisted stringing. The 916mm large diameter wheel reduces bending stress on the conductor. The nylon sheave reduces surface friction and helps protect the conductor from wear. The 50kN load capacity provides stable support for large ACSR conductor stringing.
SHDNZ916 Helicopter Stringing Blocks are widely used in:
Based on conductor size:
For ACSR700-800, SHDNZ916 with 916mm sheave is suitable.
Based on load requirement:
Choose 50kN rated load when the project involves large conductors and heavy-duty pulling.
Based on conductor protection:
Choose nylon sheave to reduce cable wear. Rubber-lined nylon sheave can be customized if higher conductor protection is required.
Based on construction method:
For helicopter stringing projects, select helicopter stringing blocks with suitable opening structure and conductor groove design.
