В вашей спецификации указано 400 КН "зажимного усилия". Как это переводится в фактическую горизонтальную тормозную силу, которая остановит мой кран? Каков коэффициент трения ваших стальных фрикционных блоков о стандартный стальной рельс?

That is an excellent and crucial question. You are correct that the effective horizontal braking force is what ultimately secures your equipment. The 400KN is the rated vertical force our YDGZ-40 clamp applies to the rail head. Our high-wear-resistant steel friction blocks are designed to achieve a stable and conservative friction coefficient (μ) of 0.25 under typical dry rail conditions. Therefore, the nominal horizontal braking force per clamp can be calculated as: Braking Force = Clamping Force × μ = 400 KN × 0.25 = 100 KN This 100 KN value is the figure you should use in your wind load and safety calculations. We recommend using this conservative value for maximum safety. For applications involving oily or wet rails, or for a more detailed analysis, our engineering team is ready to assist you in calculating the precise number of clamps required for your specific operational environment.

Как определить правильное количество рельсовых зажимов для нашего козлового крана? Можете ли вы помочь нам с расчетом?

Absolutely. Determining the correct quantity is critical, and we can certainly guide you. The primary calculation involves ensuring the total braking force from all clamps exceeds the maximum potential wind force on the crane. The basic formula is: Number of Clamps = (Total Wind Force × Safety Factor) / Braking Force per Clamp Calculate Total Wind Force (Fw): This depends on your crane's total surface area exposed to the wind, its shape, and the maximum design wind speed at your location according to local standards (e.g., EN 13001, ASCE 7). Select a Safety Factor (SF): We typically recommend a safety factor of at least 1.2 to 1.5, depending on the criticality and local regulations. Use Braking Force per Clamp: As established, this is 100 KN for the YDGZ-40. Example: If your crane has a calculated max wind force of 750 KN and you use a safety factor of 1.2, you would need: (750 KN × 1.2) / 100 KN = 9 clamps. In this case, you would likely install 10 clamps for symmetry and redundancy. We strongly encourage you to provide us with your crane's specifications and local wind speed requirements. Our technical team can perform a detailed calculation for you to ensure a fully compliant and safe configuration.

Изделие весит более тонны. Каковы особые требования к монтажу и допуски? Какую конструктивную подготовку необходимо провести на концевых тележках крана?

This is a vital point for ensuring a safe and lasting installation. Due to the significant weight (1110 kg) and the powerful forces involved, the mounting structure is critical. Mounting Surface: The clamp must be mounted on a solid, flat, and machined steel surface on the crane's end carriage or bogie. We provide a detailed mounting footprint drawing with all required bolt hole dimensions and locations. Structural Integrity: The crane structure at the mounting point must be sufficiently reinforced to handle both the static weight of the clamp and, more importantly, the dynamic reaction forces during braking. The structure must be able to withstand the full 400KN clamping force without deflection. Alignment: The clamp must be installed perfectly perpendicular to the rail to ensure the friction blocks make full contact. We provide clear alignment procedures in our installation manual. Before you purchase, we can provide you with the complete installation drawings. We recommend having your structural engineer review these drawings to verify the compatibility with your crane's design and plan for any necessary reinforcement plates or brackets. Proper preparation ensures a smooth installation and the full performance of the brake.

Каков ожидаемый срок службы стальных фрикционных колодок, подверженных высокому износу, и насколько сложно их заменить? Легко ли приобрести запасные части?

We designed the YDGZ-40 for maximum durability and minimum downtime. Service Life: The high-wear steel friction blocks have a significantly longer lifespan than traditional composite materials. In a typical parking brake application with a limited number of cycles, their mechanical life can extend for many years. The primary factor for replacement is wear. Each block has a clear wear indicator, and replacement is only needed when the thickness reaches the minimum specified limit. Ease of Replacement: The friction blocks are designed as modular components. Replacement is a straightforward process that can be performed in-situ without removing the entire clamp from the crane. It involves releasing the brake (manually or hydraulically), unbolting the worn block carrier, and installing the new one. The entire process for one clamp can typically be completed within a couple of hours by a qualified technician. Spare Parts: Yes, we maintain a full inventory of all critical spare parts, including friction block assemblies, seal kits, and limit switches. We guarantee their availability to ensure you can keep your equipment running with minimal delay.

Inherently Fail-Safe Design: Spring Applied, Hydraulic Release

At the core of the YDGZ-40’s superior safety profile is its fail-safe, normally closed design.

Braking Force: Applied by a powerful set of pre-loaded, heavy-duty disc springs.
Release Mechanism: Activated by a standard industrial hydraulic system (8 MPa).

This means the brake is always in the “on” position by default. In the event of a power failure or loss of hydraulic pressure, the springs automatically and instantly apply the full braking force. This spring applied, hydraulic release brake mechanism provides peace of mind, knowing your assets are secure even during a complete power outage.

Unmatched Holding Power: 400 KN of Clamping Force

The YDGZ-40 delivers a formidable 400 KN (approximately 40.8 metric tons) of vertical clamping force directly onto the rail. This immense power, generated through an efficient lever mechanism, creates a powerful friction lock that is essential for:

Preventing movement of large structures in high-wind conditions.
Securely parking heavy gantry cranes and ship-to-shore (STS) cranes.
Providing reliable emergency braking when integrated into the crane’s control system.

Часто задаваемые вопросы

Наиболее часто задаваемые вопросы покупателями, которые приобрели YDGZ-40 Сверхпрочный гидравлический рельсовый зажим.

В вашей спецификации указано 400 КН "зажимного усилия". Как это переводится в фактическую горизонтальную тормозную силу, которая остановит мой кран? Каков коэффициент трения ваших стальных фрикционных блоков о стандартный стальной рельс?
Это отличный и важный вопрос. Вы правы в том, что эффективная горизонтальная тормозная сила - это то, что в конечном итоге обеспечивает безопасность вашего оборудования.

400KN - это номинальное вертикальное усилие, которое наш зажим YDGZ-40 прикладывает к головке рельса. Наши фрикционные блоки из износостойкой стали разработаны для достижения стабильного и консервативного коэффициента трения (μ) 0,25 в типичных условиях сухого рельса.

Therefore, the nominal horizontal braking force per clamp can be calculated as:
Braking Force = Clamping Force × μ = 400 KN × 0.25 = 100 KN

Это значение 100 KN - цифра, которую вы должны использовать в расчетах ветровой нагрузки и безопасности. Мы рекомендуем использовать это консервативное значение для обеспечения максимальной безопасности. Если речь идет о замасленных или влажных рельсах или о более детальном анализе, наша команда инженеров готова помочь вам рассчитать точное количество зажимов, необходимых для ваших конкретных условий эксплуатации.
Как определить правильное количество рельсовых зажимов для нашего козлового крана? Можете ли вы помочь нам с расчетом?
Безусловно. Определение правильного количества очень важно, и мы, конечно, можем вам помочь. Основной расчет заключается в том, чтобы общая сила торможения от всех зажимов превышала максимальную потенциальную силу ветра на кране.

The basic formula is:
Number of Clamps = (Total Wind Force × Safety Factor) / Braking Force per Clamp

Calculate Total Wind Force (Fw): This depends on your crane’s total surface area exposed to the wind, its shape, and the maximum design wind speed at your location according to local standards (e.g., EN 13001, ASCE 7).
Select a Safety Factor (SF): We typically recommend a safety factor of at least 1.2 to 1.5, depending on the criticality and local regulations.
Use Braking Force per Clamp: As established, this is 100 KN for the YDGZ-40.
Example: If your crane has a calculated max wind force of 750 KN and you use a safety factor of 1.2, you would need: (750 KN × 1.2) / 100 KN = 9 clamps. In this case, you would likely install 10 clamps for symmetry and redundancy.
