This wire rope for truck cranes is manufactured by a JIS-certified manufacturer known for reliability, safety, and high quality.
The fundamental principle is to sell wire ropes configured as specified in the crane installation permit.
The wire rope of a mobile crane operates under harsh conditions. Even if the rope cross-section, type, rated load, configuration, rope pitch, and 1mm cross-section differ, winding 30 turns horizontally onto the drum creates a 30mm width difference. If this is wound in multiple layers, the wire cross-section will definitely affect the vertical axis as well.
For example, when winding 20mm undulations, issues like ‘step formation’ or ‘inability to properly set up’ arise. Based on over 50 years of experience and information, Aibig ships crane wire tailored to manufacturers nationwide.
Wire rope for rough terrain cranes
We can provide revised drawings for the strength calculation specifications.
Japan Quality Assurance Organization Certificate No. 138-83872 The I-Big Factory has received impartial accreditation for conducting 1000kN-class destructive testing.
We can issue and submit third-party certified strength certificates.
Please let us know at the time of ordering if necessary.
We also offer wire ropes for crawler cranes and all-terrain cranes.
Wire rope for foundations
‘Torqueless Rope’ dedicated to earth drills and full casing
This is the ultimate drilling-specific rope developed jointly with Toyo Techno.This rope features a 3-strand and 4-strand construction that simultaneously offers high non-rotation properties, strong breaking load, and soft three-dimensional flexibility.Non-rotating, high-strength, and flexible components are in demand beyond just the foundation, and are now widely used in high-load tower cranes, excavation-specific crawler cranes, and similar equipment.
The biggest advantage is the ‘single lock’, making it extremely useful for customers who want to wind it a little extra.Our locks feature the certified “SafeLock processing” by JYTEX, which is adopted by Nippon Sharyo.

All wire course terminals for earth drills are provided free of charge by our company.This eliminates the need to manually extract the gas-filled wire course at the site during wire replacement, preventing issues like swivel compatibility problems due to hole deformation and reducing the hassle of handing it over to contractors.
All-casing wire
This is also a wire rope, one of JYTEX’s strong areas.With foundation-specific machinery (BM/HLX series) now mainstream, the wire ropes they carry have also evolved beyond standard 3-strand and 4-strand ropes. Our foundation-dedicated ‘Torque-Free 3-Strand/4-Strand’ ropes deliver consistent quality and longevity, earning high praise from operators nationwide.

Wire for three-point pile driver
This is a crucial wire that passes through multiple layers of sheaves to match the height of the leader.With the increasing size of cranes, multi-layer winding (wire crossings) + high strength (all wire ropes for heavy machinery at Aibig are Type C) are becoming increasingly critical. To prevent secondary damage such as ‘indentations on sheaves’ caused by using improper wire ropes, using specialized pile-driving machine wire ropes that also possess viscosity simultaneously reduces machine maintenance costs and wire replacement frequency. This clearly demonstrates a significant advantage in total running costs.
