What is the maximum load capacity of this hydraulic safety brake?

Depending on the model, the rated braking force of the SH series brakes ranges from 1,650 Newtons (5SH model) to 230,000 Newtons (ST25SH-C model). For example, the rated braking force of the ST40SH model is up to 288,000 Newtons, while the ST3SE model can reach 147,000 Newtons in safety braking and 105,000 Newtons in rated braking. These parameters ensure that the product can meet the various needs of light-load to heavy-load industrial equipment.

What is the response speed and reaction time of the brake?

Although the specific response time depends on the system pressure and oil circuit configuration, our brakes use an efficient hydraulic control system to ensure that the braking reaction time is controlled within seconds under normal working pressure (such as the ST3SE model's safety brake pressure of 35,000 Newtons), ensuring a quick response at critical moments.

Is the performance stable when used in extreme environments (high temperature, dust, humidity)?

These brakes are made of high-quality steel and seals, and are designed to meet the standards of harsh industrial environments. For example, the ST25SH-C model has a safe braking capacity of 230,000 Newtons, which is particularly suitable for industrial scenarios with high temperatures or high dust. We can also provide special sealing and protection designs to ensure that the equipment can still operate stably in harsh environments.

Is the installation and maintenance complicated?

The product design takes into account rapid on-site installation and is equipped with detailed installation and commissioning guides. In terms of maintenance, it is recommended to check the cleanliness and pressure status of the hydraulic oil every six months to ensure that the oil circuit is unobstructed. Our technical support team can provide remote guidance or on-site assistance to help you shorten the maintenance cycle and extend the service life of the brake.

Is customization supported?

Yes, in addition to standard models, we can also customize different braking forces or special structures according to your specific equipment parameters and working conditions. For example, the ST3SH model provides a safe braking force of 147,000 Newtons and a rated braking force of 105,000 Newtons, and the parameters can be adjusted according to actual needs.

What are the prices and delivery cycles?

Prices range from $1,650to approximately $230,000, depending on the model and customization requirements. Standard models generally have a delivery time of 4-6 weeks, and complex customizations may require additional time.

What support does the manufacturer provide in the event of a failure or performance degradation?

We provide comprehensive after-sales protection, including technical consultation, fault diagnosis, parts replacement and system upgrades. For large customers, we also provide regular inspections and preventive maintenance programs to ensure that the equipment continues to operate efficiently and safely.

In the industrial sector, safety and reliability are critical to maintaining operational efficiency and personnel protection. The SH series hydraulic fail-safe disc brakes deliver precise performance backed by detailed technical specifications, making them essential for high-demand applications.

These brakes feature a compact design with rotor diameters ranging from 190mm in models like the 5SH to 600mm in larger variants such as the ST40SH. Corresponding torque capacities vary from 165 Nm to 2880 Nm. For example, the ST25SH-C model can generate a maximum braking force of 180,000N (180kN). The braking torque is calculated based on the formula:

N.m = (Braking Force (N) / 1000) × (Φ_B/2 - 60 or 75)

where ΦB is the brake disc diameter. This precise calculation ensures the brake’s torque output aligns with specific equipment requirements.

Response time for all models is zero seconds, which ensures immediate activation during emergency stop scenarios. For instance, the 904SH model has an instantaneous response with a fully released displacement volume of 33cm³ and a cylinder capacity of 98cm³, allowing rapid fluid pressure transmission and minimizing brake delay—crucial for safety in cranes, mining machinery, and port handling equipment.

Maximum braking forces differ across models: the ST16SH offers up to 150kN, while the ST10SH provides around 81kN, enabling tailored solutions for various load demands. Cylinder volumes range from 275ml (ST10SH) to 810ml (ST40SH), ensuring consistent pressure application and brake stability.

Installation accuracy is maintained with a maximum disc face runout of ±0.2mm and a perpendicularity deviation of no more than ±4‰. High-strength fasteners, such as M36 bolts graded 12.9 with tightening torque up to 4,280 Nm, guarantee secure mounting under heavy loads.

Environmental resistance is also a key feature. For outdoor or corrosive environments, certain models are available with corrosion-resistant coatings, suitable for use in harsh conditions like high humidity, salt spray, or exposure to aggressive gases. For example, the ST25SH-A model withstands release pressures up to 190 bar, with a fully released displacement volume of 95ml, ensuring consistent performance even under extreme weather.

Automatic wear compensation mechanisms, such as wear line detection on friction pads, maintain stable braking torque over the component’s lifespan, reducing maintenance frequency. The 450SH model’s wear indicator enables real-time monitoring to prevent brake failure due to excessive pad wear.

In summary, the SH series hydraulic fail-safe disc brakes combine precise torque control, rapid response, durable construction, and environmental resilience. These features address core customer needs for safety, reliability, and ease of maintenance in demanding industrial applications, providing a dependable braking solution for critical machinery across a range of high-risk sectors.
