35×7 Bull Wire Rope: In industries where lifting, hoisting, and load handling are routine, the choice of wire rope can directly impact safety, efficiency, and performance. Among the various types, rotation-resistant wire ropes are preferred for their ability to counteract torque and prevent load spin during lifting.
One standout performer in this category is the 35×7 Bull Wire Rope. Designed for high-precision lifting tasks, this rope offers several technical advantages over standard rotation-resistant ropes. In this detailed guide, we explore how 35×7 Bull Wire Rope compares, and why SSTC (Safe and Secure Trading Company) recommends it for industrial operations across Saudi Arabia.

What is 35×7 Bull Wire Rope?
The 35×7 Bull Wire Rope is a rotation-resistant wire rope made up of 35 strands, each containing 7 wires, wrapped around a Wire Strand Core (WSC). Its tightly wound multi-strand design creates a counterbalanced internal structure, minimizing the tendency of the rope to spin or rotate under load.
Key Features:
- Strand Count: 35 (7 wires per strand)
- Core Type: WSC (Wire Strand Core)
- Type: Rotation-Resistant
- Construction: (1-6) layered design for torque balance
- Common Sizes: 8mm to 32mm diameters
- Finish Options: Galvanized, ungalvanized, and plastic-coated

35×7 vs. Standard Rotation-Resistant Wire Ropes
Feature | 35×7 Bull Wire Rope | Standard Rotation-Resistant Ropes |
---|---|---|
Strand Construction | 35 strands of 7 wires each | Typically 18×7 or 19×7 constructions |
Rotation Resistance | Superior, ideal for single-line lifting | Moderate, may still allow some load spin |
Flexibility | High flexibility and drum compatibility | Moderate flexibility, more rigid under tension |
Fatigue Resistance | Excellent fatigue resistance under bending and reeving | Good, but depends on construction |
Hoisting Stability | Minimal torque transmission and high load stability | May require load guides to reduce spin |
Abrasion Resistance | Moderate (due to thinner wires) | Higher in some standard ropes with fewer thick wires |
Longevity Under Load | Long lifespan in precision applications | Shorter lifespan if misused in torque-sensitive tasks |
Price Point | Slightly higher due to complex design | Lower initial cost |
Why 35×7 is Ideal for Saudi Arabia’s Industrial Applications
With Saudi Arabia leading major infrastructure, oil & gas, and logistics projects, the demand for high-performance lifting gear is growing rapidly. From the Neom megaproject to mining and port operations, reliable lifting solutions are non-negotiable.
35×7 Bull Wire Rope excels in:
- Extreme heat and dusty desert environments
- Heavy lifting in construction and rigging
- Precise positioning in mechanical maintenance
- Offshore lifting and marine supply hoists
- Oil and gas sector for crane ropes and snatch blocks
Top Applications of 35×7 Bull Wire Rope
1. Tower and Mobile Cranes
35×7 wire ropes eliminate dangerous spin during lifting, ensuring safety on construction sites using tower or truck cranes.
2. Offshore Cranes & Marine Hoists
Its rotation resistance and flexible winding make it ideal for winches and cranes on ships, rigs, and offshore platforms.
3. Elevator Systems in High-Rise Buildings
Smooth winding and high strength make it a preferred rope for modern service elevators, especially in high-capacity lifts.
4. Material Handling in Ports & Logistics
Helps manage heavy cargo containers with precise control, reducing the chance of spinning or swinging.
5. Wind Turbine Maintenance
Used to lift components to tall heights without twisting the load—a must-have in renewable energy sectors.
6. Mining Operations
Supports skip hoisting, shaft lifting, and ore transport with resistance to shock loads and abrasion.
Engineering Comparison: Inside the Rope
Structure
- 35×7: More strands, smaller wires → High flexibility, low torque
- 18×7 or 19×7: Fewer strands, thicker wires → Stiffer, less flexibility
Load Behavior
- 35×7 maintains its shape and performance even during high-speed lifts or multi-layer spooling.
- Standard ropes may torque, causing twisting or damage over time.
Handling and Installation
- 35×7 ropes are easier to bend over sheaves and wrap around drums.
- Less likely to develop bird-caging or internal wire breaks.
Specification Snapshot
Diameter (mm) | Weight (kg/100m) | Min Breaking Load (kN) | Coating Option |
---|---|---|---|
10 | 45.5 | 85.0 | Galvanized/Ungalvanized |
16 | 110.0 | 215.0 | Plastic-coated available |
20 | 170.0 | 325.0 | Optional anti-corrosion oil |
Safe Handling Practices
Even the best ropes need proper care. To get the most from your 35×7 Bull Wire Rope:
- Inspect regularly for broken wires, kinks, and corrosion
- Lubricate to reduce friction and prevent rust
- Avoid overloading beyond rated capacity
- Reeving correctly across sheaves ensures longer rope life
- Replace if there’s excessive rotation or visible damage
