Грейферный ковш (clamshell bucket)

Clamshell bucket.
Weight 270 kg.
Volume 170 l.
Intended hydraulic pressure 180 bar.
Designed in consideration with good digging characteristics.
High clamping forces, compact design, relatively high weight.
High construction rigidity – intended good working life.
Designed as multi – purpose bucket with easily exchangeable hydraulic cylinders, and by so, providing high clamping speed in loose (low density) soil applications – and high clamping force in compact (higher density) applications.
Project unfinished due to lack of funds. It requires - bearings, greasing system, parallel action lever pins, bushings, cylinder fastening & sealing, wear resistant blades (initially intended hardox 500) and tooth.
