30 Tons Overhead Crane Core Features

30 टन ओवरहेड क्रेन

The 30 tons overhead crane integrates advanced engineering, safety design, and user-friendly functionality, with the following key advantages:

1. मजबूत संरचनात्मक डिजाइन: The main beam and end beams are fabricated from high-strength Q345B steel, undergoing strict welding and heat treatment processes. This ensures excellent load-bearing capacity, resistance to deformation, and long-term durability even under frequent heavy-load operations.
2. Comprehensive Safety Protection: Equipped with multiple safety devices to eliminate operational risks:
- Overload protection device: Automatically cuts off power when the load exceeds 110% of the rated capacity, preventing structural damage.
- Upper/lower limit switches for hoisting: Stops the hook from overtraveling, avoiding collisions with the crane frame or ground.
- Emergency stop button: Enables immediate shutdown of all mechanisms in case of emergencies.
- Anti-sway system: Reduces load swing during movement, improving positioning accuracy and preventing load damage.
3. High Operational Efficiency:
- The hoisting mechanism adopts a high-torque variable-frequency motor, supporting stepless speed regulation (0.8-8 m/min for hoisting, adjustable based on load weight).
- The crane (अनुदैर्ध्य यात्रा) and trolley (transverse travel) mechanisms use precision gearboxes and rail clamps, ensuring smooth movement and positioning accuracy within ±5mm.
4. बुद्धिमान नियंत्रण प्रणाली: Adopts PLC (क्रमादेश योग्य तर्क नियंत्रक) with a touchscreen HMI (मानव मशीन इंटरफेस). Operators can monitor real-time data (load weight, travel speed, working hours) and adjust parameters easily. Remote control is optional for scenarios requiring long-distance operation.
5. Easy Maintenance & Low Downtime: ज़रूरी भाग (मोटर्स, कम करने वाली, बीयरिंग) use internationally renowned brands (उदा।, सीमेंस, एबीबी) for reliable performance. The crane is designed with accessible maintenance hatches and lubrication points, simplifying routine inspections and reducing maintenance time.

Double girder overhead crane

While both models handle 30 टन, their structural designs and application scenarios differ significantly. The following table compares key aspects:

तुलना आयाम	Single-Girder 30 टन ओवरहेड क्रेन	Double-Girder 30 टन ओवरहेड क्रेन
संरचनात्मक डिज़ाइन	Single main beam (I-beam or box beam) supported by end beams.	Two parallel main beams (box beams) connected by crossbeams.
