Technical Core of Belt Arrestor
Dual-Mode Intelligent Trigger Mechanism
It flexibly adapts to two trigger modes according to different load scenarios to ensure accurate and efficient response. Light-load belt arrestors (rated braking force 50-200kN) adopt pure mechanical + gravity drive, requiring no external power supply, hydraulic station or other auxiliary equipment. Triggered by changes in belt tension and gravity sensing, they can work reliably in extreme environments such as no electricity, humid salt spray and -40℃ low temperature, avoiding failure caused by electromagnetic interference or power interruption. General-purpose belt arrestors (300-600kN) and heavy-load models (800-1500kN) incorporate hydraulic auxiliary triggering, compressing the response time to 0.2-0.3 seconds, far exceeding the industry average. The hydraulic system adopts an explosion-proof design, and together with tension monitoring sensors, it captures fault signals in real time to realize a fully automated "monitoring-judgment-trigger" process, adapting to high-throughput and high-belt-speed heavy-load scenarios.
Full Belt Surface Bidirectional Locking Structure
The equipment adopts a symmetrical wedge-shaped brake block structure to achieve 100% full belt surface bidirectional capture. After triggering, the brake blocks on both sides synchronously tighten towards the center of the belt, not only locking the carrying section of the belt to prevent material rollover and falling, but also fixing the return section of the belt to avoid stacking and winding around the drum, completely eliminating the loophole of "one-sided slip". The brake blocks are made of REACH-compliant polyurethane and rubber composite materials, subjected to special wear-resistant treatment, with a slip resistance coefficient of no less than 0.8, balancing braking friction and belt protection to avoid secondary damage. The braking deceleration is strictly controlled at 0.2-0.5m/s², and the inertial impact force is absorbed through the buffer structure to prevent equipment resonance or structural deformation.
Convenient Installation and Strong Environmental Adaptability
The product frame is made of Q235B/Q355B high-strength section steel and alloy steel, inspected by ultrasonic flaw detection, with defects meeting JB/T4730.3 Level I standard, capable of withstanding instantaneous impact force. Two frame types are available: fixed and suspended. Light-load and general-purpose models support quick-installation fixture mounting, requiring no welding or drilling, and a single set can be deployed within 2 hours, which can be easily adapted to existing belt conveyors; heavy-load models adopt bolt fixing + foundation reinforcement design to ensure installation stability in high-inclination and high-throughput scenarios. The product has a protection level of IP65-IP67 and a corrosion resistance level in line with ISO 12944-6 C4-C5-M standard. Key components undergo double treatment of galvanizing + spray coating, capable of resisting erosion from harsh environments such as dust, salt spray and corrosive gases, with an operating temperature range of -40~+60℃, adapting to different climate regions around the world.

Applicable Scenarios
Mining Industry
Mining conveyor lines are mostly high-inclination and high-throughput working conditions, with large material impact, fast belt wear and prominent belt breakage risks. Relying on dual-trigger technology, ZOOMRY's heavy-load belt arrestor can quickly lock the belt at the moment of breakage, avoiding a large amount of material falling to damage equipment or cause collapse risks. Meeting the explosion-proof requirements of underground coal mines, the product has passed ATEX and MA certifications, with a protection level of IP67, adapting to high-dust and humid environments, and working in collaboration with self-owned conveying equipment to ensure production continuity.
Port Industry
Belt conveyors supporting ship loaders and stackers at port bulk terminals are characterized by large belt width, high belt speed and complex operating environment. Belt breakage accidents may cause materials to fall into the ocean or yards, resulting in environmental pollution and operation interruption. ZOOMRY's general-purpose and heavy-load belt arrestors adopt anti-corrosion coating and high-protection design to resist salt spray erosion. The full belt surface bidirectional capture avoids belt winding around the drum, and links with the automatic control system to realize fault alarm and emergency shutdown, ensuring safe and efficient terminal operations.
Power Industry
Coal conveying systems in thermal power plants and nuclear power plants need to operate continuously for 24 hours, and belt breakage accidents will directly lead to power generation interruption. ZOOMRY's general-purpose belt arrestor is suitable for medium and low inclination angle working conditions in power plants. The pure mechanical + gravity drive mode does not rely on external power supply, avoiding protection failure during power outages. The product links with the PLC control system, and synchronously cuts off the power supply and sends remote alarms when triggered, facilitating operation and maintenance personnel to quickly handle and reduce downtime.
Building Materials Industry
Aggregate and clinker conveyor lines in cement plants and mixing stations mostly handle corrosive or highly abrasive materials. ZOOMRY's light-load and general-purpose belt arrestors can be flexibly adapted according to material characteristics, with core components made of anti-corrosion or high-wear-resistant materials to extend service life. Used in conjunction with self-owned feeders and unloaders, they are compatible with belt conveyors of different widths, avoiding production line shutdown caused by belt breakage accidents.
Belt Arrestor Selection Guide
- Confirm the core parameters of the conveyor and materials. Clarify the belt width, inclination angle, belt speed and belt strength of the belt conveyor, as well as the material type and weight per unit length. Determine the minimum braking force through mechanical calculation to ensure the selected model matches the requirements, avoiding waste or insufficient protection.
- Adapt to working conditions, environment and compliance requirements. For explosion-proof scenarios, select models with ATEX or MA certification; for coastal, port and other scenarios, prioritize products with high corrosion resistance level; for exported products, confirm the corresponding certification and standard requirements of the target market.
- Consider host matching and maintenance needs. For ZOOMRY's own hosts, directly select the corresponding adapted model; for adapting to other brand hosts, provide parameters such as frame size and installation space. For remote unattended scenarios, models with intelligent diagnosis function can be selected; for mobile belt conveyors, lightweight and quick-installation frames are preferred.
