Hydraulic grab buckets (clamshell buckets) are available in hydraulic‑rotary and fixed types. Fixed types use the standard bucket circuit; rotary types require extra valves and lines.
Applications:
Excavation of foundation pits and loading of mud, sand, coal, gravel.
Single‑side excavation in trenches or confined spaces.
Loading/unloading on ships, trains, and trucks. Welding quality and hydraulic cylinders determine strength and service life.
