A high-strength alloy steel triple diamond U-bar mesh feller chain that delivers superior ground bite and balanced load distribution across rugged off-road terrain — built for feller bunchers, skidders and heavy forestry & construction machinery that need heavy-duty traction and long-wear structural durability, not just basic smooth-ground anti-slip performance.
The triple diamond U-bar mesh feller chain pairs a robust alloy chain net body with a triple diamond mesh layout and U-stud & I-bar traction system, giving the unit enhanced ground biting traction and impact load resistance on rugged terrain in addition to reliable anti-skid performance. Available in three series — TDU-14, TDU-16 and TDU-18 — with tire sizes from 500/45-22.5 up to 73×44.00-32 and per-pair weights ranging from 186 kg to 895 kg, it's built for feller bunchers, heavy skidders and construction & forestry machinery that need heavy-duty traction and long-wear structural durability across harsh off-road environments, not just basic smooth-ground grip.
It shares its high-strength alloy steel construction with standard forestry skidder chains, but adds a triple diamond mesh pattern and U-bar traction design for superior grip and even load distribution — see the specification table below to confirm which model fits your equipment.
It features a triple diamond alloy chain net structure with U-stud and I-bar dual grip design, delivering superior ground bite and strong traction on complex terrain.
Made of high-strength alloy steel, it resists frequent friction from gravel, tree roots and soil, with excellent fracture resistance for long durability in harsh heavy-duty conditions.
Available in TDU-14, TDU-16 and TDU-18 series, covering tire sizes from 500/45-22.5 to 73×44.00-32, with 186–895 kg per-pair weight to fit various skidders, feller bunchers and work vehicles.
Engineered for mud, ice, gravel and steep mountain roads in forestry and construction. It has a robust impact-resistant structure and a dedicated locking device to prevent shifting on bumpy ground.
Not every forestry or construction job needs heavy-duty double-ring or floating-ring reinforced construction. Where a machine operates on standard forest roads with moderate loads — routine felling, light log hauling, general forest maintenance — a triple diamond mesh feller chain does the job at lower cost and with simpler fitting than a premium double-ring or floating-ring unit. The TDUX series is built for exactly that: dependable, cost-effective traction for everyday forestry and construction operations.
Which TDUX model fits your job? If you run smaller tires from 500/45-22.5 up to 700/55-34 with light to medium loads, the TDU-14 delivers solid triple diamond grip at 186–394 kg per pair for everyday felling and forestry work. If you need medium-heavy capacity for tires from 750/45-30.5 up to 780/55-28.5, the TDU-16 at 380–626 kg per pair offers balanced traction and durability for standard feller bunchers. If you have large heavy-duty tires like 710/45-26.5 up to 73×44.00-32 for high-tonnage skidding, the TDU-18 at 596–895 kg per pair provides robust build for the heaviest forestry workloads. All models feature triple diamond alloy chain net construction, U-stud & I-bar traction, high-strength alloy steel and a built-in locking device to resist loosening on bumpy terrain.
