ENJUE multi-flap grab is a highly efficient loading and unloading device developed for handling steel scrap, bulk materials, and complex waste. It utilizes a modular design concept and a dynamic claw adjustment system to precisely grasp various material forms. It has been successfully deployed in ports, metallurgical plants, and mines in over 30 countries worldwide, demonstrating exceptional operational stability under extreme working conditions.
Core Advantages of the multi-flap grab
Intelligent Shape Adaptation System
The unique bionic claw structure automatically detects material contours with an error of ≤2mm. The claw closing angle is infinitely adjustable from 0° to 180°, accommodating a full range of gripping sizes – from thin plates to bulky objects. The patented anti-slip tooth design increases gripping force by 40% while significantly reducing material dropout.
Innovative Powertrain of Multi-Flap Grabs
The electric version is equipped with a permanent magnet synchronous motor, achieving an energy efficiency of 92%. The hydraulic system utilizes load-sensing technology, reducing no-load energy consumption by 65%. The four-rope structure enables high-speed lifting and lowering of 0.5 m/s, increasing operating efficiency by three times.
