Crane Grab Buckets

Crane grabs are specialized tools that attach to cranes, enabling efficient and secure lifting and transportation of bulk materials. They come in various configurations to suit different applications, with two of the most common types being the clamshell grab and the orange-peel grab.Based on the above two forms of crane grabs, we will choose different drive forms for you according to your specific use scenario, including two-rope, four-rope, hydraulic, as well as electric winch closure mechanisms.

The orange-peel grab consists of multiple jaws or tines that resemble the segments of an orange peel. It is designed to handle irregularly shaped and bulky materials with ease.

The clamshell grab features two equally-sized buckets or shells that open and close like a clamshell. It is typically made from high-strength steel to withstand rigorous use in demanding environments.

Product Description

The crane grab is an essential attachment designed for various lifting and handling operations. Its robust construction and versatile functionality make it indispensable in industries such as construction, mining, shipping, and waste management. The crane grab is engineered to enhance productivity, ensure safety, and streamline operations, making it a valuable addition to any material handling equipment inventory.
