Introduction

Introduction to Crane Coupling

The Crane Coupling is a key connecting component in crane drive systems, linking devices such as motors, reducers, and drums to transmit torque and align shafts. Made of high-strength alloy with precision processing, it features impact resistance, wear resistance, and axial deviation compensation, ensuring smooth crane operation as a core 传动 (drive) component for overhead cranes, gantry cranes, and more.

Key Advantages:

· Reliable Torque Transmission: High-precision alignment design with a torque range of 50-5000N·m, minimizing power loss for high-speed, heavy-duty applications.

· Vibration & Shock Absorption: Elastic elements (e.g., jaw pads, diaphragms) absorb operational vibrations and shocks, reducing noise and extending drive system life by over 20%.

· Durable & Weather-Resistant: Quenched and galvanized surfaces adapt to dusty, wet, and wide-temperature (-40℃~+80℃) industrial environments.

· Easy Installation: Modular structure enables quick disassembly/assembly, compatible with different shaft diameters (φ30-φ300mm) and connection types (flange, gear, universal).

Application Scenarios:

· Overhead/Gantry Cranes: Power transmission for trolley, bridge, and hoisting mechanisms.

· Jib Cranes/Electric Hoists: Shaft alignment compensation between motors and reducers for precise operation.

· Port Machinery: High-load transmission in quay cranes and portal cranes.

· Heavy Manufacturing: Heavy-duty couplings for large equipment assembly lines.

Prohibited Environments:

· Prohibited from operating beyond the rated torque (exceeding 10%+) or under frequent start-stop overload.

· Prohibited from forced installation when shaft deviation exceeds limits (radial >0.5mm, angular >1.5°) to avoid abnormal wear.

· Prohibited from long-term use without lubrication (lubrication cycle >6 months) or in corrosive media (acids, alkalis, salt spray).

Customization Services:

· Basic Parameters: Torque range, shaft diameter, connection type (rigid/elastic), and protection grade.

· Material Upgrades: Stainless steel (corrosion resistance), high-strength nylon (lightweight), low-temperature alloy (-40℃ below).

· Functional Extensions: Torque monitoring sensors, explosion-proof coatings, or custom flange hole spacing for special equipment layouts.
