Designed with a six-petal linkage and four-rope drive, the FPG series is ideal for handling low-density, irregular bulk materials with densities ranging from 0.6 to 2.5 t/m³. It excels in complex applications such as port cleanup, waste processing, and scrap metal recycling, offering precise grabbing, efficient bottom clearing, and minimal residue.
The FPG four-rope orange peel grab is ideal for handling irregular materials in harsh environments such as scrap steel, municipal waste, hazardous industrial waste, and ores.
It is designed for use with overhead or gantry cranes, and requires two sets of drum winches. Each set connects two wire ropes: one set for lifting and lowering, connected to the grab's balance frame; and the other set for opening and closing, connected to the grab's pulley block.
Core Technical Advantages
Six-Petal Linkage Grabbing
- Petal-type closing structure increases the grabbing area by 40%, adapting to irregular materials (such as scrap iron and stones).
- Three-mode design (full closing/half opening/full opening) ensures a material residue rate of <3%, especially suitable for cleaning the bottom of cargo holds and silos.
Four-Cable Coordinated Drive
- 5× closing cable system improves opening/closing speed by 20%, with a response time of <1 second.
- Pulley diameter of 280-900mm, compatible with 5t gantry cranes to 50t ship unloaders, supporting high-frequency operations.
High-Strength Lightweight Design
- Made of Q345B low-alloy high-strength steel, with a self-weight 15% lighter than similar products and energy consumption reduced by 12%.
- Joint bearing rotation points + maintenance-free design extend service life to over 10 years.
Global Working Condition Adaptation
- Supports 380V/440V voltage and 50Hz/60Hz frequency, complying with EU CE and US OSHA safety standards.
- Customizable anti-corrosion coatings (such as epoxy resin) adapt to high-salt fog, acidic and alkaline environments.
