Overview
The DZ Series Band Brake is specifically engineered for marine cranes, providing reliable braking for slewing, hoisting, and luffing mechanisms. Designed for demanding offshore environments, this brake series ensures operational safety and consistent performance, making it an ideal solution for maritime lifting equipment.
Key Advantages
Safe and Stable Operation Spring-applied and hydraulically released, the DZ Series delivers smooth and reliable braking even under high-frequency operation. Perfect for applications requiring frequent start-stop cycles.
Compact and Lightweight Design
With a simple yet robust structure, the brake is lightweight and easy to install. Key pivot points feature self-lubricating bearings, eliminating the need for regular greasing and minimizing maintenance efforts.
Environmentally Friendly Materials
Asbestos-free brake linings are used to ensure compliance with environmental and health safety standards. A green, responsible choice for modern industrial applications.
High Efficiency and Long Service Life
Designed for high transmission efficiency and durability, the DZ Series maintains strong performance even under harsh working conditions. High-wear components are built to last, reducing downtime and replacement costs.
Corrosion-Resistant for Marine Environments
Anti-corrosion models are available for use in environments exposed to rain, snow, salt spray, or corrosive gases. Operates reliably across a wide temperature range from -20°C to 40°C.
Key Advantages
- High Torque Capacity: Rated torque up to 46,300 Nm suitable for heavy-duty marine crane applications.
- Marine-Grade Durability: Corrosion-resistant construction designed for offshore and maritime environments.
- Hydraulic Release: Spring-applied, hydraulically released design ensures fail-safe operation.
- Low Maintenance: Self-lubricating bearings and asbestos-free linings reduce maintenance requirements.
