Three-Wheel Grounding Pulley Block Φ60/75mm for Ø6–32mm ACSR Earthing Cable Hanging Stringing Blocks
Designed for earthing cable hanging, ACSR conductor guiding, transmission line maintenance and power line installation work.
Product Overview
The Three-Wheel Grounding Pulley Block is engineered for earthing cable hanging, ACSR conductor guiding, transmission line maintenance and power line installation work.
Two standard models are available: SHL75D with Φ75 mm aluminum sheave and SHG60D with Φ60 mm steel sheave. The pulley block is suitable for conductors from Ø6 mm to Ø32 mm, depending on the selected model.
Its compact three-wheel structure helps guide the grounding cable smoothly and keeps the cable stable during overhead line work.
Common Challenges
During transmission line grounding or cable hanging operations, contractors often face:
- Cable surface wear during pulling or hanging
- Unstable grounding cable positioning
- High friction when the cable moves over fixed supports
- Low efficiency during overhead line maintenance
- Difficulty guiding small-diameter ACSR or earthing cable safely
Root Causes
- Direct contact between cable and metal support points
- Improper pulley groove size
- Insufficient cable guiding structure
- Single-point support causing cable shaking
- High friction during repeated cable movement
Our Solution
The Three-Wheel Grounding Pulley Block solves these problems by:
- Three-wheel guiding design → improves cable stability
- Φ60/75 mm pulley diameter → supports smooth cable movement
- Aluminum or steel sheave options → suitable for different working conditions
- Compact structure → easy to carry and install on site
- Suitable for Ø6-32 mm conductor → covers common earthing cable and small ACSR applications

How It Works
The grounding cable or ACSR conductor is placed between the three pulleys. During operation, the cable moves along the rotating sheaves instead of rubbing directly against the metal structure.
The three-wheel design keeps the cable in position. The smooth pulley groove reduces cable wear. The aluminum model is lighter and easier to carry. The steel model offers stronger wear resistance for tougher site conditions.
This helps improve cable protection, installation efficiency and field operation stability.
Applications
This grounding pulley block is widely used in:
- Transmission line installation
- Overhead line grounding work
- Earthing cable hanging
- ACSR conductor guiding
- Power line maintenance
- Cable pulling and cable support work
- Utility construction and repair projects
Selection Guide
For larger applicable conductor range:
Choose SHL75D, Φ75 mm aluminum sheave, suitable for Ø6-32 mm conductor.
For stronger wear resistance:
Choose SHG60D, Φ60 mm steel sheave, suitable for Ø6-25 mm conductor.
For lightweight field operation:
Aluminum sheave model is easier to carry and install.
For tougher working conditions:
Steel sheave model is more durable and suitable for repeated use.
