A failure of the wire rope can lead to catastrophic accidents—making it the most safety-sensitive component on the crane.
Q1: What is the function of steel wire rope on a tower crane?
1.Hoisting & Lowering
2.Support & Guidance: Travels over sheaves and drums, providing precise control of the load’s movement.
3.Force Transmission: Transfers power from the hoist motor to the load with high strength and flexibility.
Q2: Where is it used on a tower crane?
1.Main Hoist Rope: Connects the hoist drum to the hook block for primary lifting.
2.Trolley Rope (on luffing cranes): Controls the horizontal movement of the trolley along the jib.
3.Slew Ring Lubrication Rope (in some models): Used for automatic lubrication system routing.
4.Anchoring & Bracing Ropes: In some installations, used for temporary guying or securing.
Q3: Why is selecting the correct wire rope so important?
1.Safety: Prevents breakage under maximum load, including safety factor requirements.
2.Durability: Matches the crane's duty cycle.
3.Cost Efficiency: Reduces replacement frequency and downtime.
4.Compliance: Meets international standards.
Q4: What are common daily issues and how to address them?
Issue | Possible Cause | Prevention & Action |
Wire Breakage | Overload, fatigue, corrosion, or abrasion. | Regularly inspect; never exceed SWL; replace at first sign of damage. |
Kinking or Birdcaging | Improper installation or handling. | Train crews on correct unspooling and installation. |
Corrosion | Exposure to moisture, salt, chemicals. | Use galvanized rope; store covered; apply recommended lubricant. |
Uneven Wear | Misaligned sheaves, rope twist. | Check sheave alignment and groove condition monthly. |
Reduced Diameter | Core collapse or excessive stretch. | Measure diameter regularly; replace if beyond allowable tolerance. |
Q5: How can proper maintenance extend rope life?
1.Look for broken wires, corrosion, deformation, or damage at terminations.
2.Document rope diameter and wear patterns.
3.Apply wire rope lubricant periodically to reduce internal friction and prevent rust.
4.Sheave Inspection
5.Record Keeping
