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 quiet steel storyteller who pulls instead of pushes. A custom 160 mm heart and 90 mm rod give her the gentle strength to keep crane gates from sagging, while the 2 550 mm stroke reaches like a long sigh. Single-acting design means gravity helps her home—no extra hoses, no fuss. Built-in seal grooves hug O-rings like lifelong friends, keeping river mist and dust outside where they belong. OEM fit lets her bolt straight onto the boom, no shims, no late-night cursing. Day after quiet day she murmurs, “Hold tight, I’ll take the strain,” and the operator breathes easier.
Application scenes:Picture sunrise at a lock gate: she pulls the massive leaf open, letting barges glide through while coffee steam curls in the cold air. Or a flood barrier at dusk, lowering inch by inch so towns sleep dry. From port cranes lifting dock gates to hydropower stations cradling turbine guards, she’s the calm hand that keeps water and steel on speaking terms. Wherever gravity needs a polite but firm tug, she’s already there, turning tonnage into a gentle handshake.
