The tube follows GUOYUE CD250 style.
Tube steel can be 45#, 42CrMo, or 27SiMn.
Hole is ground to H8 and feels smooth, Ra under 0.4 μm.
Head, base, ears, and piston are only 45# steel.
We do not use cast iron or cast steel. Slow-Down Parts
You can pick fixed bumpers or floating bumpers so the rod slows down safe at any speed or load. Welds
We hit every heavy-load weld with ultrasound.
This takes away most of the stress and makes the weld last longer. Seals
We only use top seals from NOK (Japan), Trelleborg (Sweden), Merkel and GP (Germany).
We do not use local seals. Checks
Each cylinder is tested to GB/T15622-2005 and our own Q/GAKY014-2023.
You get a test sheet and a pass paper. Promise
We give one year cover from ship date.
If it breaks because of how we made it, we fix or swap it for free.
This cylinder is strong. It uses thick steel and hard rod. It does not bend. The seal keeps oil in, no leak. It has many tubes that slide out one by one. It lifts high but stays short Advantages:
She’s the gentle giant with city-smarts and country muscle. A 200 mm bore and 125-210 mm telescopic heart give her the reach to kiss the riverbed and the grunt to hoist tons of silt. Hard-chrome skin laughs at salt, grit, and accidental knocks, while the built-in seal groove hugs every O-ring like a lifelong promise—no leaks, no tears. Custom ports let the hydraulic pump talk to her in perfect rhythm, so the dredge arm glides instead of jerks. OEM fit means she bolts straight on, no shims, no late-night cursing. Day after muddy day she whispers, “Push deeper, I’ll keep the flow smooth,” and the crew believes her. Application scenes :
Picture dawn on a cutter-suction dredger: muddy water swirls, and she stretches her chrome neck to guide the draghead down, sipping riverbed treasure without waking the herons. Or a barge unloading sand under city lights, telescoping higher with every scoop until trucks roll away full and quiet. From canal clean-ups to offshore mining, she’s the gentle giant turning cramped decks into wide-open possibility, keeping tomorrow’s waterways—and today’s dreams—running clear.
