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

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 who steadies the crane’s dance. Custom-built to unfold the outriggers with a soft touch, her nested sleeves stretch like a morning yawn, giving the crane the wide stance it needs to stay steady. Chrome skin laughs at dirt and dust, while balanced oil paths keep every move smooth and quiet. Day after day she whispers, “I’ll keep you grounded,” and the crane stands tall without a wobble. Application scenes:
Picture a city street at dawn: the mobile crane unfolds its legs with a gentle hiss, thanks to her steady push. Or a construction site where she helps the crane spread its outriggers wide, lifting beams into place without a shudder. From urban high-rises to roadside repairs, she’s the quiet heartbeat that keeps the crane balanced and safe, turning tight spaces into wide-open possibilities.
