Single sheave stringing block
Single sheave stringing block SHD & SHDN series for LGJ overhead conductors. Available in hook style and clevis type, aluminum sheave and nylon sheave options. Rated load 5–20kN, multiple sizes, custom specifications supported. Factory direct supply for power transmission construction.
Product Description
Our single sheave stringing block is widely used for stringing LGJ steel-cored aluminum conductors on overhead transmission and distribution lines.
Two series available:
- SHD series — Aluminum sheave: high strength, wear-resistant, designed for heavy-duty pulling and long service life
- SHDN series — Nylon sheave: protects the conductor surface, low friction, no damage to the wire
Two mounting types: hook style and clevis type. Please specify the type clearly in writing when placing your order. Special sizes and specifications can be customized.
Model definition: sheave outer diameter × sheave width (mm). Example: SHD-120×30 means sheave OD 120 mm, width 30 mm.
Features:
- High-strength alloy steel frame, hot-dip galvanized anti-corrosion finish
- Smooth-running sheave, low pulling resistance
- Compact and lightweight, easy to carry on site
- Full size range matched to LGJ25–LGJ500 conductors
- OEM / ODM and customized specifications available
Applications: overhead transmission line stringing, distribution line construction, OPGW and optical cable pulling, conductor tensioning operations.

Frequently Asked Questions
Q1: What are the two mounting types of this single sheave stringing block?
A: Hook style and clevis type. Please specify the type in writing when placing your order.
Q2: What is the difference between SHD and SHDN series?
A: SHD uses an aluminum sheave with high wear resistance for heavy pulling work. SHDN uses a nylon sheave that protects the conductor surface and prevents wire damage.
Q3: What does the model code mean?
A: Model = sheave outer diameter × sheave width (mm). For example, SHD-120×30 means sheave OD 120 mm, width 30 mm.
Q4: Which conductors are these pulleys suitable for?
A: They are designed for LGJ steel-cored aluminum conductors, covering LGJ25 to LGJ500. Please refer to the specification table for the matching model.
Q5: Can you manufacture customized sizes?
A: Yes, special specifications and customized dimensions are acceptable.
Q6: What is the rated load based on?
A: The rated load in the table is the safe working load for overhead conductor stringing operations.
Q7: What certificates can you provide?
A: Factory test certificates and inspection documents can be provided as required.
Q8: What is your MOQ and lead time?
A: MOQ and delivery time depend on model and quantity. Please send your list for an exact quotation.
