نظرة عامة على المنتج

ال 50 tons double girder overhead crane adopts a double main girder structure, which is scientifically designed to distribute the load evenly, ensuring excellent bearing capacity and structural stability even under long-term full-load operation. مع قدرة رفع مقدرة 50 طن, it can be flexibly configured with different spans (ranging from 10m to 35m) and lifting heights (من 6 م إلى 30 م) according to the actual needs of the workplace, adapting to various large-scale factory buildings and operation spaces. The whole crane is composed of main girder, end girder, عربة, آلية الرفع, آلية السفر, electrical control system and safety protection device, each part is strictly tested and manufactured to meet international industry standards, ensuring long-term reliable operation.

50 Tons Double Girder Overhead Crane Technical Specifications

50 Tons Double Girder Overhead Crane Core Structural Advantages

• 1. Double Girder Structure: Compared with single girder cranes, the double girder design has larger load-bearing capacity and better stability. The main girder is made of high-quality Q355B steel plate, which is formed by professional welding and heat treatment, effectively eliminating welding stress, improving structural strength and durability, and avoiding deformation under heavy load. The optimized cross-section design of the main girder also reduces the self-weight of the crane while ensuring bearing capacity, saving energy consumption during operation.
• 2. High-Performance Hoisting Mechanism: The hoisting mechanism adopts a high-power variable-frequency motor and a hard-tooth surface reducer, which has the advantages of smooth lifting, ضوضاء منخفضة, high transmission efficiency and strong overload capacity. The wire rope is made of high-strength galvanized steel wire, which is wear-resistant, corrosion-resistant and has a long service life, ensuring safe and stable lifting of 50-ton heavy objects. The hoisting speed can be steplessly adjusted, realizing precise positioning of heavy objects, which is suitable for occasions requiring high-precision handling.
• 3. Stable Traveling Mechanism: Both the crane traveling (longitudinal travel) and the trolley traveling (transverse travel) adopt frequency conversion speed regulation, which ensures smooth start and stop, no impact, and effectively protects the crane structure and the lifted objects. The traveling wheel is made of wear-resistant cast steel, which is matched with a high-precision bearing, reducing friction resistance and improving traveling stability and accuracy. The traveling mechanism is also equipped with a buffer device and a limit switch to prevent collision and ensure safe operation.

Intelligent Control & Safety Protection

ال 50 tons double girder overhead crane is equipped with an advanced electrical control system, which adopts PLC control and touch screen operation, with simple operation, clear display and strong operability. The control system has multiple protection functions such as overload protection, overvoltage protection, undervoltage protection, phase failure protection and emergency stop, which can timely cut off the power supply when an abnormality occurs, avoiding safety accidents.

فضلاً عن ذلك, the crane is also equipped with a variety of safety devices: the lifting height limit switch prevents the hook from overtraveling; the trolley and crane travel limit switches prevent collision with the end of the track; the overload limiter can accurately detect the lifting load, and issue an alarm and cut off the hoisting power supply when overloaded; the anti-sway device reduces the sway of heavy objects during lifting and traveling, improving operation safety. All safety devices meet the requirements of international safety standards, providing all-round protection for operators and equipment.

50 Tons Double Girder Overhead Crane Application Scenarios

With its strong load-bearing capacity and stable performance, ال 50 tons double girder overhead crane is widely used in various heavy-duty industries:
