A multi-ring floating alloy skidder chain with 25mm tag chain construction that delivers adaptive traction and stress dispersion on rugged forest terrain — built for heavy skidders and high-tonnage logging machinery that need low-stress fatigue resistance and terrain-conforming performance, not just standard rigid skidder chain traction.
The RAFT Series multi-ring floating alloy skidder chain pairs a 25mm tag chain framework with floating alloy lug ring assemblies — including the main lug ring and side lug ring — giving the unit optimized load distribution, impact damping and superior terrain adaptability in addition to heavy-duty tensile strength on rugged forest terrain. Available in RAFT305-25, RAFT355-25 and RAFT7300-25 models, fitting tire sizes from 305×32 up to 7300×44×32 with per-pair weights ranging from 853 kg to 963 kg, it's built for heavy skidders and high-load logging equipment that need enhanced fatigue resistance and floating traction performance, not just standard rigid-structure forestry chains.
It shares its fully hardened all-link build with standard heavy skidder chains, but adds a multi-ring floating alloy design for reduced stress concentration and extended service life — see the specification table above to confirm which model fits your machinery.
Dual floating alloy main & side lug rings self-adjust to terrain undulations, disperse working stress, and improve impact damping and traction stability.
25mm Tag Chain serves as the load-bearing framework; all links are through-hardened for enhanced tensile strength, wear and fracture resistance under heavy skidding loads.
3 models available: RAFT305-25, RAFT355-25, RAFT7300-25. Fits tire sizes from 305×32 to 7300×44×32, weighing 853–963 kg per pair, compatible with various skidders and logging equipment.
Floating ring structure reduces stress concentration for extended fatigue life. Hardened construction delivers durable performance for high-load skidding on steep, rugged and muddy forest terrain.
Not every forestry operation requires the same traction and load resistance. Where a skidder works on steep, muddy or rugged woodland terrain — logging sites, slope harvesting zones, rough forest trails — ordinary tire chains tend to suffer breakage and insufficient grip. The RAFT Series is built for exactly that: dependable heavy-load traction with terrain adaptability.
Which RAFT model fits your job? If your skidder is fitted with 305×32 tires, RAFT305-25 is your match. For 355×32 tire size, choose RAFT355-25. If your tire specification is 7300×44×32, RAFT7300-25 will be the option. All models feature 25mm Tag Chain base plus multi-ring floating alloy rings, with all links perfectly hardened for enhanced durability.

| Stock# | Fitting Tire Size | Wt./pair(kg) | Remarks |
| RAFT305-25 | 305×32 | 853 | the main lug ring 38x280, the side lug ring 32x180 |
| RAFT355-25 | 355x32 | 963 | |
| RAFT7300-25 | 7300×44x32 | 952 |
If your equipment only operates on maintained forest roads with standard loads, a standard studded skidder chain is the simpler, more economical choice.
Choose from RAFT305-25, RAFT355-25 and RAFT7300-25 based on your exact tire dimensions, plus proper fitting tolerance.
Confirm the main lug ring (38×280) and side lug ring (32×180) dimensions, and per-pair weight (853–963 kg) match your axle load before ordering.
Select all-link perfectly hardened construction with 25mm tag chain base to match your terrain severity and heavy skidding operation intensity.
Multi-ring floating alloy structure for excellent terrain adaptability
Dual main & side lug ring configuration for superior traction & support
25mm tag chain base for robust structure & high load capacity
Fully hardened all-link construction for outstanding wear & fracture resistance
Three graduated models for wide equipment compatibility
Low-stress fatigue-resistant design for extreme heavy off-road conditions
From what working scenarios can the RAFT skidder chain work?
It delivers heavy-duty traction and driving stability for extreme forestry operations — steep-slope skidding, mountain timber harvesting, off-road log hauling, and operation on muddy, rutted and rugged forest terrain, when fitted to skidders, feller bunchers and heavy logging carriers.
What models and tire sizes does it come in?
The RAFT series includes three models: RAFT305-25, RAFT355-25 and RAFT7300-25, fitting tire sizes from 305×32 up to 7300×44×32, with per-pair weights ranging from 853 kg to 963 kg.
How does the multi-ring floating alloy structure deliver better performance?
The chain adopts a floating alloy ring design with main lug rings and side lug rings, which self-adjusts to terrain undulations, disperses working stress and cushions impact. The dual-ring combination maximizes ground bite and lateral stability on loose, steep and slippery surfaces.
What material treatment and chain specification does it feature?
It is built with a 25mm Tag Chain as the load-bearing base, and all chain links receive precision through-hardening treatment for enhanced hardness, tensile strength and abrasion resistance in harsh off-road conditions.
What type of forestry equipment is it designed for?
It features a multi-ring floating alloy construction purpose-built for extreme heavy off-road uses, compatible with heavy skidders, feller bunchers and high-tonnage logging machinery for continuous high-intensity forest harvesting operations.
