Engineered to prevent slip-back and optimize material flow at steep gradients under extreme humidity.
As the world’s largest exporter of thermal coal and a global powerhouse in nickel, copper, and bauxite extraction, Indonesia presents some of the most challenging material handling environments globally. The open-pit mines of East Kalimantan and South Sumatra, coupled with processing refineries across Sulawesi, require massive volumes of bulk materials to be moved rapidly, often across steep gradients and restricted spaces.
Standard smooth flat conveyor belts typically lose operational efficiency at incline angles exceeding 15 to 18 degrees, leading to dangerous material rollback, loss of capacity, and accelerated surface cover wear. Hebei Boao Rubber Technology's premium "Jinao" Brand Chevron Conveyor Belts are specifically optimized for these exact conditions, offering stable steep-angle transport up to 40 degrees, ensuring continuous throughput even in heavy monsoonal rainfall conditions that are common across the Indonesian archipelago.
Designed to optimize conveying capacity and resist profile abrasion in extreme environments.
Our chevron profiles are hot-vulcanized integrally with the cover rubber, not cold-bonded. This ensures a monolithic structure that completely eliminates profile delamination under extreme high-torque loading.
Offered in Open V, Closed V, Herringbone, and Multi-V patterns with heights ranging from 15mm up to 32mm. Custom engineered to support materials ranging from wet sand and clay to coarse minerals and coal lumps.
Formulated with specific antioxidants and anti-ozonants to resist the degrading effects of humid, tropical maritime air, preventing premature micro-cracking in the cover rubber.
Our engineering team can calculate the exact profile configuration and carcass strength (EP/NN/Steel Cord) needed for your specific angle of inclination and material density.

Nickel laterite ore is notoriously sticky and highly abrasive. Under heavy rainfall, it becomes a slurry-like substance. Our closed-chevron profiles trap materials, preventing runoff, while the high-abrasion cover compound minimizes surface loss from sharp ore particles.
Indonesian cement facilities require high-angle transport for clinker, limestone, and additives. Combining heat resistance with chevron profiles allows for high-inclination transport of semi-hot materials without compromising the structural integrity of the carcass.
Fast-loading ports in Samarinda, Banjarmasin, and Bunati rely on steep conveyor systems to feed bulk carriers. Using premium flame-retardant (FR) chevron belts prevents hazardous fire spread while maintaining maximum conveyor volume throughput.
Indonesia's massive palm oil sector requires oil-resistant, FDA-compliant conveyor options. Our specialized oil-resistant (OR) compound stops cover swelling and delamination when transporting oily palm kernels or byproducts at high gradients.
Established in 2004 in Boye County Rubber Industrial Park, Baoding, Hebei, China, Hebei Boao Rubber Technology Co., Ltd. covers an area of over 30 acres. Over the past 22 years, our "Jinao" brand has become synonymous with engineering rigor and premium raw material integration.
We feature an completely independent chemical analysis room and physics laboratory. This guarantees that raw materials, from natural rubber polymers to synthetic reinforcing agents and steel cables, undergo rigorous evaluation before compounding. Our quality inspectors enforce a zero-tolerance policy: no unqualified raw materials enter our mixers, and no non-conforming belt leaves our vulcanizing lines.
