In the key link of the steel circular economy - scrap steel grabbing and processing, Enjue hydraulic orange peel grab has achieved a technological leap from "zero leakage" to "zero loss" by virtue of the dual innovation of self-developed closed-loop hydraulic channel technology and high-wear-resistant alloy materials, providing core equipment support for steel companies to reduce costs, increase efficiency, and meet environmental protection standards.
Traditional hydraulic orange peel grabs rely on exposed return lines, which are prone to hydraulic oil leakage and line damage due to impact from scrap materials, resulting in downtime and environmental pollution. Enjue's unique closed-loop hydraulic channel technology completely seals the hydraulic oil circulation within the grab cylinder body. A built-in check valve and piston structure ensure unidirectional flow of hydraulic oil, eliminating the risk of exposed lines. Field tests have shown that this technology reduces hydraulic oil leakage by 90%, improves the protection level by 300%, reduces equipment failure rate by 65%, and reduces hydraulic oil leakage by over 5 tons annually. Enjue has received EU Ecodesign certification and China Environmental Protection Product certification.

Material Innovation: Highly Wear-Resistant Alloy Extends Service Life
The grab jaws are constructed from a composite material of high-manganese steel ZGMn13 and tungsten carbide alloy. Through quenching and surface coating, they achieve a hardness of HRC58-62 and a 200% increase in wear resistance. In use by companies like Baowu Group, this material enables the grab to maintain high grip strength even in high-temperature, dusty environments, increasing single-pass handling capacity by 40% and extending its service life to 2.5 times that of conventional products, reducing equipment replacement frequency and resource waste.
Circular Economy Support: Full Lifecycle Carbon Management
Enjue hydraulic orange peel grab technology is deeply integrated into the steel circular economy:
Efficient Scrap Recovery: Precision gripping reduces material spillage to below 0.5%, increasing the annual scrap recovery rate by 5%, equivalent to reducing iron ore mining by 100,000 tons per year.
Energy Cascade Utilization: Combined with the hydraulic servo system, it reduces energy consumption by 30%, resulting in an annual carbon reduction equivalent to planting 20,000 trees.
Full Lifecycle Carbon Management: A supporting digital twin system monitors energy consumption and emissions in real time, generates carbon footprint reports, and optimizes operational strategies, achieving a 20% reduction in carbon emissions over the entire lifecycle.
The Enjue hydraulic orange peel grab, centered on "zero-loss" technology, utilizes closed-loop hydraulic channels and innovative, highly wear-resistant alloy materials to achieve efficient, low-consumption, and environmentally friendly scrap steel handling. It not only brings direct economic benefits to companies but also plays a key role in the steel industry's circular economy, promoting efficient resource utilization and achieving carbon emission reduction goals, setting a benchmark for the green manufacturing era.
