The selection, usage, and maintenance of wire ropes

1.Choosing Wire Ropes:
a. For elevators or aviation, use specialized wire ropes made for those purposes.
b. Tower cranes with high lifting requirements should go for ropes tailored for them.
c. For cranes, pile drivers, drills, shovels, excavators, etc., pick ropes that are durable, fatigue-resistant, and can handle impacts well, like 629Fi or 635SW.
d. Opt for metal core wire ropes for equipment operating in high-temperature environments or those needing high breaking strength.
e. Shipments, maritime, fishing, or wood binding tasks demand corrosion-resistant and flexible ropes, so go for A-class galvanized ropes like 619, 624, 6*37, etc.
Also, choose the rope's tensile strength based on the load and required safety factor, instead of blindly pursuing high strength. Select the right strength level based on equipment characteristics and operational conditions to ensure safety, prolong lifespan, and improve economic efficiency.

2.Using Wire Ropes:
a. Unwinding: Use a dedicated stand or a rod inserted through the reel holes, then rotate the reel slowly to unwind.
b. Arrangement on the Drum: Ensure orderly winding on the drum according to the rope's twist direction to avoid tangling.
c. Cutting: Use cutting tools to shear the rope, leaving about 10-20mm of ends, then bind them with iron wires before cutting.

3.Maintenance and Inspection of Wire Ropes:
a. Operation: Ensure steady speed during operation, avoid overloading, and prevent impacts.
b. Maintenance: Although ropes come lubricated, they lose grease over time, attracting dust and debris leading to wear and rust. Regularly clean and lubricate them using appropriate tools and oils.
c. Inspection Records: Regularly inspect ropes for wear, breakage, corrosion, and check vulnerable parts like hooks and pulley grooves for damage. Address any issues promptly.
