Overview
Crane with a grab bucket is a type of crane equipped with a grabbing mechanism, usually in the form of a bucket, that is used to lift and transport loose materials such as sand, gravel, or debris. The grab bucket is attached to the cranes lifting mechanism, allowing it to open and close to grab and release materials as needed.
Crane wheel and wheel shaft through the high frequency quenching and tempering treatment, it eliminates the internal stress and ensures the machining accuracy.
Sinokocranes pioneers the use of welding robot, the main girder inseam weld by advanced MAG welding. The main girder welding adopts radiographic testing and ultrasonic testing to ensure the welding quality.

You can choose from a range of grab bucket volumes—typically from 0.5 m³ up to 3 m³, each powered by a high‑performance electric motor; common configurations include 1 m³, 2 m³, and beyond, to suit handling requirements from 2.5 t to 10 t crane SWL (Safe Working Load).
The grab frame is fabricated from Q345 steel, while the grab peels are also Q345 with edges made of high wear‑resistant steel, ensuring long‑lasting performance in harsh scrap environments.
It features a built‑in hydraulic system driven by an electric motor; the crane supplies power and control signals via cable, operating hydraulic cylinders that open and close the grab.
The grab mechanism achieves up to IP65 protection rating, offers a coating thickness of up to 180 µm, and includes safety features such as limit switches, overload protection, emergency stop systems, and weatherproof covers for outdoor components.
Ideal for handling steel scrap, irregular blocks, bulk materials in steel mills, scrapyards, foundries, and charging furnaces. Variants also serve garbage incineration, wharfs, and stone or waste yards.
Key factors include:
Daily handling capacity and maximum material load per grab
Operational schedule—continuous 24‑hour vs. intermittent use
Required span, maximum lift height, and travel distances
Preferred control method (e.g., pendant control, wireless remote, cabin)
Optionally, whether a hybrid grab + magnet configuration is needed for versatile material handling.
