Excavator hydraulic clamshell grab

Excavator hydraulic clamshell grabis mainly composed of a lifting device, a bolster, an oil cylinder, a sub-fluid and a bucket body. The bucket body and the bolster are connected by a pin; the piston end of the oil cylinder is fixed above the bolster, and the piston rod is fixed on the upper part of the bucket body. As the cylinder piston rod is retracted and extended, the bucket body rotates with the pin of the bearing pin as a hinge point, completing the opening and closing of the grab bucket. The connecting plate effectively adjusts the open and closed positions of the two buckets to ensure that the left and right buckets rotate synchronously.The hydraulic double-claw bucket is used with an excavator and is not powered by itself, relying on the high-pressure hydraulic oil provided by the excavator as a power source. The excavator leads all the way high-pressure hydraulic oil into the grab opening and closing system, controlling the opening and closing of the grab by controlling the extension and retraction of the hydraulic cylinder; drawing another high-pressure hydraulic oil into the grab rotating system, and controlling the grab by controlling the rotation of the hydraulic motor. Bucket rotation.
