Lembar spesifikasi Anda menyebutkan 'gaya penjepit' sebesar 400KN. Bagaimana hal ini diterjemahkan ke dalam gaya pengereman horizontal yang sebenarnya yang menghentikan derek saya? Berapa koefisien gesekan blok gesekan baja Anda terhadap rel baja standar?

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.

Bagaimana cara menentukan jumlah klem rel yang tepat untuk derek gantry kami? Dapatkah Anda memandu kami dalam menghitungnya?

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.

Produk ini memiliki berat lebih dari satu ton. Apa saja persyaratan dan toleransi pemasangan yang spesifik? Persiapan struktural seperti apa yang perlu kami lakukan pada gerbong ujung derek kami?

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.

Berapa masa pakai yang diharapkan dari blok gesekan baja dengan keausan tinggi, dan seberapa sulitkah untuk menggantinya? Apakah suku cadang sudah tersedia?

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.

Pertanyaan yang Sering Diajukan

Pertanyaan yang paling sering diajukan oleh pelanggan yang membeli YDGZ-40 Penjepit Rel Hidraulik Tugas Berat.

Lembar spesifikasi Anda menyebutkan 'gaya penjepit' sebesar 400KN. Bagaimana hal ini diterjemahkan ke dalam gaya pengereman horizontal yang sebenarnya yang menghentikan derek saya? Berapa koefisien gesekan blok gesekan baja Anda terhadap rel baja standar?
Itu adalah pertanyaan yang sangat bagus dan krusial. Anda benar bahwa gaya pengereman horizontal yang efektif adalah yang pada akhirnya mengamankan peralatan Anda.

400KN adalah gaya vertikal terukur yang diterapkan penjepit YDGZ-40 kami ke kepala rel. Blok gesekan baja tahan aus kami yang tahan aus dirancang untuk mencapai koefisien gesekan (μ) yang stabil dan konservatif sebesar 0,25 dalam kondisi rel kering yang khas.

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

Nilai 100 KN ini adalah angka yang harus Anda gunakan dalam perhitungan beban angin dan keamanan. Kami merekomendasikan penggunaan nilai konservatif ini untuk keamanan maksimum. Untuk aplikasi yang melibatkan rel berminyak atau basah, atau untuk analisis yang lebih rinci, tim teknisi kami siap membantu Anda dalam menghitung jumlah klem yang tepat yang diperlukan untuk lingkungan operasional Anda yang spesifik.
Bagaimana cara menentukan jumlah klem rel yang tepat untuk derek gantry kami? Dapatkah Anda memandu kami dalam menghitungnya?
Tentu saja. Menentukan jumlah yang tepat sangatlah penting, dan kami pasti dapat memandu Anda. Perhitungan utama melibatkan memastikan gaya pengereman total dari semua klem melebihi potensi gaya angin maksimum pada derek.

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.
