Application of OUCO Clamshell Grab Bucket
Clamshell grab buckets are widely used for grabbing bulk materials such as grain, fertilizer, and sand. However, they are not suitable for irregular materials such as scrap steel and stones. It is important to select the appropriate grab bucket for the specific material to be handled.
At OUCO, our products are classified into lightweight, normal, and heavy-duty clamshell grab buckets, depending on the weight of the material to be grabbed. Our clamshell grab buckets are made to be fully closed, half-closed, or enclosed, depending on the specific gravity of the material, to prevent exceeding the safe working load of the grab.

The clamshell grab is one of the most common load handling devices in lifting machinery.
Structurally, it consists of two symmetric buckets (or “shells”) connected by a central hinge.
It gets its name because it opens and closes just like a giant seashell to trap loose material inside.
The Clamshell is the workhorse of bulk handling.
Best For — Loose materials like sand, coal, grain, and gravel.
Not For — Delicate items or precision placement (it’s a scooper, not a finger).
It is highly versatile and works as an attachment for almost any equipment, including Marine Cranes, Gantry Cranes, Mobile Truck Cranes, and Excavators.
We classify them by how they are powered:
1. Mechanical Clamshell: The “classic” type. It has no motor and relies entirely on the crane’s steel ropes and pulley system to open and close.
2.Hydraulic Clamshell: Powered by hydraulic cylinders built into the grab. It connects to an excavator or a hydraulic pump station for strong closing force.
3.Remote Control (Battery) Clamshell: The modern solution. It uses an onboard rechargeable lithium battery and is operated wirelessly via a remote control unit.
