A double-ring skidder chain with 25mm tag chain base and dual main & side lug rings that delivers reinforced traction and balanced load distribution on rugged forest terrain — built for heavy skidders and high-tonnage logging machinery that need heavy-duty structural durability and dual-ring gripping performance, not just basic standard forestry chain traction.
The RAM series double-ring skidder chain pairs a 25mm tag chain framework with a dual-ring assembly of main lug rings and side lug rings, giving the unit reinforced traction, even load distribution and excellent structural stability on steep and rugged off-road terrain. Available in three models including RAM305-25, RAM355-25 and RAM7300-25, fitting tire sizes from 305×32 up to 7300×44×32 with per-pair weights of 850–970 kg, it's built for heavy skidders, feller bunchers and heavy logging machinery that need fully hardened wear resistance and dual-ring load-bearing capacity, not just basic standard forestry chain performance.
It adopts a double-ring design composed of main lug rings (38×280) and side lug rings (32×180). Main lug rings provide core biting traction, while side lug rings supplement lateral support and optimize load distribution, balancing strong traction and structural stability.
A 25mm Tag Chain serves as the overall load-bearing framework, sized to match the operating loads of heavy skidders. It delivers secure connections and high structural strength, withstanding continuous tensile and torsional forces under heavy-duty working conditions.
All chain links receive precision through-hardening treatment, comprehensively enhancing hardness, tensile strength and abrasion resistance. With excellent impact and fracture resistance, it adapts to harsh forest terrain such as rugged trails and steep slopes, effectively prolonging service life.
It covers three models: RAM305-25, RAM355-25 and RAM7300-25, fitting tire sizes of 305×32, 355×32 and 7300×44×32 respectively. With per-pair weights ranging from 850 kg to 970 kg, it is compatible with skidders and heavy logging equipment of different tonnages.
Not every forestry operation requires heavy-duty dual-ring traction and reinforced load bearing. Where vehicles travel on maintained forest roads with light to medium loads — standard logging trucks, light utility tractors — a basic mesh forestry chain does the job at lower cost and with lighter weight than a double-ring skidder chain. The RAM Series is built for exactly that: dependable heavy-load traction and structural durability for rugged off-road skidding operations.
Which RAM model fits your job? If your skidder runs on 305×32 tires, the RAM305-25 delivers reliable double-ring grip at 850 kg per pair for standard forestry tasks. If you operate equipment with 355×32 tires, the RAM355-25 offers higher load capacity at 970 kg per pair for heavier skidding work. For larger 7300×44×32 tire sizes, the RAM7300-25 at 930 kg per pair is the suitable choice. All models feature a 25mm tag chain base with main and side lug rings, with all links perfectly hardened for extended service life.

| Stock# | Fitting Tire Size | Wt./pair(kg) | Remarks |
| RAM305-25 | 305x32 | 850 | the main lug ring 38x280, the side lug ring 32x180 |
| RAM355-25 | 355×32 | 970 | |
| RAM7300-25 | 7300×44x32 | 930 |
If your equipment only operates on maintained forest roads with standard loads, a basic mesh forestry chain is the simpler, more economical choice.
Choose from RAM305-25, RAM355-25 and RAM7300-25 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 (850–970 kg) match your skidder's 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.

From what working scenarios can the RAM skidder chain work?
It delivers heavy-duty traction and structural stability for rugged forestry operations — steep-slope skidding, mountain timber harvesting, off-road log hauling, and operation on muddy, rutted and uneven forest terrain, when fitted to skidders and heavy logging machinery.
What models and tire sizes does it come in?
The RAM series includes three models: RAM305-25, RAM355-25 and RAM7300-25, fitting tire sizes from 305×32 up to 7300×44×32, with per-pair weights ranging from 850 kg to 970 kg.
How does the double-ring structure deliver better performance?
The chain adopts a double-ring design with main lug rings and side lug rings working in synergy. It enhances ground biting grip, optimizes load distribution paths, and greatly improves overall structural stability and heavy-load operating capacity.
What chain specification and hardening treatment 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 forest conditions.
What type of forestry equipment is it designed for?
It features a double-ring reinforced construction purpose-built for heavy-duty off-road uses, compatible with heavy skidders, feller bunchers and high-tonnage logging machinery for continuous high-intensity forest harvesting operations.
