SHINING's WRB5289 is a heavy-duty incline conveyor chain engineered exclusively for the Palm Oil industry. Designed as a direct, high-performance replacement for the original Ewart standard, it reliably transports Fresh Fruit Bunches (FFB) on steep slopes under severe abrasive conditions. Featuring superior tensile strength, an anti-derailment screw pin lock, and enhanced wear resistance, it ensures maximum uptime and a proven service life of 12+ months in demanding palm oil mills.
Overview
SHINING's WRB5289 is the industry-standard, heavy-duty incline conveyor chain engineered exclusively for the Palm Oil industry. Designed as a direct, high-performance replacement for the original Ewart WRB5289, this chain is the critical component for the efficient and reliable slope conveyance of Fresh Fruit Bunches (FFB) in palm oil mills. It is built to withstand the severe, abrasive conditions of palm oil processing—including constant exposure to mud, high humidity, and organic acids—ensuring uninterrupted operation on inclines typically between 15° to 30°.
WRB5289 Palm Oil Chain Key Features & Benefits
Palm Oil Industry Optimized: Specifically engineered for the unique challenges of FFB transportation. The chain's design, material, and heat treatment are all selected to combat the extreme wear from fruit bunches, spines, and the corrosive mill environment.
Superior Strength for Heavy Loads: Manufactured from premium alloy steel and subjected to precise heat treatment, the chain delivers a minimum ultimate tensile strength of 311.4 kN, reliably handling the intense, continuous loads of 18-20 hour daily operation in milling plants.
Anti-Derailment & Secure Connection: The extended screw pin with a locking nut is a critical safety feature that prevents pin back-out and chain separation on steep, vibrating incline conveyors, maximizing operational safety and preventing costly downtime.
Enhanced Abrasion & Impact Resistance: Key wear parts like pins are surface hardened, while rollers and sidebars are through-hardened. This provides exceptional resistance to the abrasive action of FFB and mud, significantly extending service life compared to standard chains.
Guaranteed Compatibility & Longevity: Precision-machined to the exact 6-inch pitch and dimensional specifications of the Ewart WRB5289, it ensures a perfect fit with existing conveyor systems and sprockets. Proven to deliver a service life of 12 months or more in demanding Southeast Asian mill conditions.
WRB5289 Palm Oil Chain Typical Applications
Primary Application: Incline/ramp conveyor systems for transporting Fresh Fruit Bunches (FFB) in Palm Oil Mills.
Specific Use Case: The main chain for slope conveyors that lift FFB from receiving hoppers to sterilizer stations or between processing stages.
Industry: Exclusively serves the Palm Oil Milling and Plantation sector.
