雙樑橋式起重機

雙樑橋式起重機是一種高效率的起重機。, heavy-duty material handling equipment designed for indoor and semi-outdoor industrial applications. It integrates a stable double-girder structure with a reliable hoist system, enabling precise lifting, 降低, and horizontal transportation of heavy loads. Widely used in factories, 倉庫, 研討會, 端口, and metallurgical plants, this crane is recognized for its strong load-bearing capacity, 使用壽命長, and excellent operational stability, making it an indispensable core equipment for modern industrial production lines.

產品概述

Our double girder overhead crane with hoist is engineered to meet the diverse needs of heavy-load handling, with a load capacity ranging from 5 噸至 500 tons and a span of 10 米到 35 儀表 (customizable according to customer requirements). The crane consists of two parallel main girders, 末端卡車, a traveling mechanism, a hoist system, and an electrical control system. The double-girder design distributes the load evenly, reducing stress concentration and ensuring higher stability compared to single-girder overhead cranes, especially when handling ultra-heavy or bulky loads. The matched hoist (electric wire rope hoist or electric chain hoist) is selected for its high lifting efficiency, low noise, and strong durability, realizing seamless coordination with the crane’s traveling movement.

Double Girder Overhead Crane with Hoist Technical Parameters

Core Structural Advantages

250 Tons Double Girder Overhead Crane With Hoist

• 1. Sturdy Double-Girder Structure: Adopting high-quality Q235B or Q355B steel plates, the main girders are welded by submerged arc welding technology, which ensures high structural strength, good rigidity, and resistance to deformation. After strict flaw detection and heat treatment, the girders can withstand long-term heavy-load operation without damage.
• 2. 行走機構穩定: The end trucks are equipped with high-precision gears and bearings, combined with frequency conversion speed regulation technology, enabling smooth starting, stopping, and traveling. The crane travels along the track laid on the factory roof, with low friction and low energy consumption, ensuring accurate positioning of loads.
• 3. Integrated Hoist System: The hoist is perfectly integrated with the crane’s trolley, which can move horizontally along the main girders. The hoist’s lifting mechanism is equipped with a safety brake and overload protection device, preventing accidents caused by overloading or sudden power failure. The lifting speed is adjustable, adapting to both fast material transportation and precise positioning.
• 4. Compact Design: The crane’s overall structure is compact, occupying small vertical space, which helps save factory height and expand usable space. The detachable design facilitates transportation, 安裝, 和維護, reducing the difficulty and cost of on-site construction.

Key Components Introduction

1. 提升系統

提升系統

The hoist is the core lifting component of the 雙樑橋式起重機, available in two types: electric wire rope hoist and electric chain hoist. The electric wire rope hoist is suitable for heavy-load lifting (above 10 噸), with a steel wire rope made of high-strength carbon steel, featuring wear resistance, 耐腐蝕性, and high breaking strength. The electric chain hoist is suitable for medium and light loads (below 10 噸), with a lightweight design and flexible operation. Both types are equipped with a variable-frequency motor, which realizes stepless speed regulation, reducing impact on loads and the crane structure during lifting and lowering.

2. 主梁 & 末端卡車

末端卡車

The main girders are the main load-bearing parts, adopting a box-type structure or I-beam structure, which effectively improves the structural rigidity and load-bearing capacity. The end trucks are connected to the two ends of the main girders, providing support and driving force for the crane’s traveling. The wheels of the end trucks are made of forged steel, with high wear resistance and long service life, and are equipped with anti-derailment devices to ensure safe traveling.

3. 電氣控制系統

電氣控制系統

The electrical control system adopts PLC control technology, which is stable, 可靠的, and easy to operate. It is equipped with a remote control (wireless or wired) and an on-site control panel, enabling operators to control the crane from multiple positions. The system has multiple protection functions, 包括過載保護, overcurrent protection, voltage protection, and emergency stop function, ensuring the safety of operators and equipment.
