Required
characteristics |
Tips to consider |
Typical
application |
| Flexibility |
Ropes with fiber core of the rope are more flexible
Ropes with fiber core of each strands are more flexible
Point contacting wire type rope is more flexible than plane contacting type rope.
The more the number of wires make the rope more flexible
|
SLING
LASHING |
|
Plane contacting wire type rope is more appropriate than point contacting wire type rope.
The more numbers of wires make the rope more flexible.
The more numbers of strands make the rope moreflexible except for multi-layers ropes.
When there are too many wires, a wire can be easily worn out
The more the number of strands, the more rotating characteristics, except for multi-layers ropes.
|
Crane |
| Breaking load |
Plane contacting wire type rope has better breaking load than point contacting wire type rope
The higher tensile strength of wires, the higher breaking strength
Independent wire rope core has better breaking load than fiber core
Plane contacting lay rope has better breaking load than point contacting rope
|
|
| Elongation |
The fewer the number of wires, the less elongation
Point contacting wire type rope maintains less elongation than plane contacting wire type rope
Fiber core shows more elongation, then IWRC and IWSC in order
|
Pendent
Bridge hanger
Cable Way & Elevator |
| Anti-abrasion |
The smaller number of wires, the better anti-abrasion
Flattened type, swaged, and parallel wires ropes with flat surface are better in terms of anti-abrasion
Parallel wires are better than non-parallel wires in terms of anti-abrasion
|
Cable Way & Logging
Roperail
Mining |
| Maintaining good form |
Parallel wires are better than non-parallel wires in terms of form
IWRC is better than fiber core in terms of form
The smaller number of wires and strands is better in terms of form
Parallel wires and flattened type of ropes are better in terms of form
|
|
| Rotation |
Non-rotating ropes to be required
The longer the rope rolled, the more rotation
Using Z twist rope together with S twist rope helps to prevent rotation
Plain lay has less rotation than Langs'lay
The smaller radius of sheave groove, the more rotation
The smaller number of strands, the less rotation except for plural layers rope
|
High lifting
crane
Messengers
span wires |
| Anti-corrosion |
Galvanized ropes are required in working environment where risk of corrosion exists
Ropes with smaller number of wires (thicker wires) are better in terms of corrosion
Rope grease has good aspect in terms of corrosion
Fiber core is better than wire core in terms of corrosion
Even though the working condition is agreeable, corrosion must be considered for a long time use
|
Fishing
Pendent
Hanger
Anchor |
| Temperature |
Wire core is required because fiber core is weak at high temperature
Black grease is required for environment of high temperature, and if necessary, special grease for high temperature must be used
Red grease is appropriate for environment of lower temperature
