Technical Features of Broken Belt Catcher
Full-Section Synchronous Locking
Breaking through the limitation of traditional single-side capture, it adopts a symmetrical wedge-shaped brake block structure. At the moment of belt breakage, the brake blocks on both sides synchronously tighten towards the center of the belt, locking both the carrying section and the return section simultaneously to achieve 100% full-section coverage. This completely eliminates secondary risks such as belt slipping, stacking and material falling. The frame is made of Q355B high-strength section steel and alloy steel composite, inspected by ultrasonic flaw detection, and can withstand instantaneous impact of 1.5 times the design load. Combined with buffer braking technology, it precisely controls deceleration to avoid equipment damage.
Full-Scenario Modular Adaptation
Adopting modular precise parameter configuration, it fully covers from light load to heavy load and from small belt width to large belt width. There is no need to distinguish the conveying direction, and it is universally applicable for upward, downward and horizontal conveying. It features standardized interface design with ZOOMRY's own host equipment such as belt conveyors, bucket wheel stacker-reclaimers and Mobile Ship Loaders, enabling quick matching without additional modification. For conveying equipment of other brands, customized adaptation services can be provided by adjusting frame size and installation interfaces to achieve seamless cross-brand and cross-equipment compatibility.
Full-Standard Compliance Guarantee
Following the design principle of "global standard integration", it fully complies with core standards such as China's NB/T 11464-2023, EU EN 12895, North American ASTM D3794 and international ISO 5048. It has obtained CE Certification, ATEX Explosion-Proof Certification, MA Coal Mine Safety Mark Certification and REACH Compliance Certification. Whether for the domestic market or overseas markets such as Europe, North America and Southeast Asia, it can directly meet access requirements without additional adaptation and modification.
Core Advantages of Broken Belt Catcher
Full Protection Coverage
The full-section synchronous locking design achieves 100% protection coverage, far exceeding traditional single-side capture equipment. The rated braking force reserves sufficient safety redundancy, enabling stable capture even under extreme loads. The braking deceleration is precisely controllable, balancing protection effect and equipment protection, and fundamentally eliminating various safety accidents caused by belt breakage.
Wide Adaptation Range
The Broken Belt Catcher covers 50-1500kN braking force, 650-2200mm belt width, 800-4000N/mm belt strength, and adapts to full inclination angles of -25~+32°, meeting the needs of different scenarios such as light-load small conveyor lines and heavy-load large belt conveyors. It reduces the complexity of customer selection and the cost of spare parts storage, and one product family can cover full-scenario protection needs.
Stable Operation in Extreme Environments
The operating temperature ranges from -40~+60℃, adapting to complex environments such as extreme cold in frigid zones, high temperature in tropical zones, salt spray in coastal areas, and high dust in mines. With a protection level of IP65-IP67 and corrosion resistance level complying with C4-C5-M standard, key components undergo special anti-corrosion treatment, capable of resisting erosion from humidity, dust and corrosive gases, and the failure rate is much lower than the industry average.
Convenient Operation and Maintenance
Core components adopt a modular design. Wear parts are common with ZOOMRY's existing components such as idlers and cleaning scrapers, facilitating procurement and replacement. The design life is no less than 10 years. Daily maintenance only requires regular visual inspection and brake block wear detection, no complex professional tools are needed, and the long-term operating cost is significantly lower than that of similar imported products.
