Product Description

European Model Double Girder Overhead Bridge Crane 25ton 30ton Double Lifting Speed EOT Crane

Overhead Crane, commonly known as a "bridge crane," is a lifting device that operates on overhead rails. Its primary feature is the combination of longitudinal movement along the bridge girder and transverse movement of the hoist trolley, creating a rectangular working area. This design allows for efficient material handling beneath the bridge girder without obstruction from ground-level equipment. This type of crane typically consists of a bridge metal structure, hoisting mechanism, trolley travel mechanism, crane travel mechanism, and electrical control system.

Specification

Technological Evolution and Drive Control

Modern overhead cranes, particularly our standard designs, extensively incorporate modular construction and variable frequency drive (VFD) technology. VFD delivers numerous benefits through precise motor speed regulation:

Smooth Start/Stop: Effectively minimizes load sway and vibration, enabling pinpoint positioning.

Energy Efficiency: Reduces current surges during startup and lowers energy consumption.

Equipment Protection: Reduces impact on mechanical transmission components, extending service life.

Additionally, the widespread adoption of wireless remote control technology significantly enhances operational flexibility and safety. Operators can work at optimal viewing angles away from the load point, minimizing safety hazards.

Core Components and Technical Parameters

Core Components:

Girder: Manufactured from Q235B or Q345B/E steel in a box-type structure, featuring automated welding and non-destructive testing to ensure robust durability.

Hoist: Typically equipped with European standard wire rope electric hoists or chain electric hoists, serving as the core component for lifting heavy loads.

Travel Mechanism: Includes main crane travel (bridge movement) and trolley travel (trolley movement). Utilizes either integrated drive units (combining motor, brake, and reducer) or separate drives. Wheels may employ high-quality materials like 42CrMo to ensure wear resistance.

Electrical System: Incorporates variable frequency drives, PLC controllers, and safety protection devices (e.g., limit switches, overload limiters, anti-collision systems). Protection rating typically meets IP54 or IP55 standards, suitable for industrial environments with dust and humidity.

Safety Components: Include brakes, reducers, and safety limit devices.

Primary Applications

Overhead cranes find extensive use across virtually all industrial settings requiring vertical and horizontal handling of heavy materials.

1. Manufacturing and Assembly Workshops

In automotive and machinery manufacturing, they transport large components, mold assemblies, and transfer work-in-progress between production line stations. High-precision positioning is critical for precision assembly.

2. Metal Processing and Metallurgy

This represents the quintessential application for double-girder overhead cranes. Specific uses include:

Raw Material Handling: Unloading steel coils, plates, and profiles, then transporting them to storage or processing areas.

Feeding and Cutting: Precisely positioning large metal plates onto laser cutters, plasma cutting tables, or shearing machines.

Inter-process Transfer: Moving semi-finished components between workstations such as bending, welding, and machining.

Specialized Metallurgical Cranes: Examples include foundry cranes (handling ladles), tong cranes (gripping ingots), and de-molding cranes-all engineered for extreme operating conditions.

3. Warehouses and Logistics Centers

Used for rapid loading/unloading, stacking, and material retrieval within warehouses. Maximizes vertical space utilization to enhance warehouse capacity and turnover efficiency.

4. Power Plants and New Energy

In hydroelectric, thermal, nuclear power plants, and wind/solar equipment manufacturing facilities, used for hoisting large critical equipment like generator rotors, turbines, and transformers.

5. Ports and Terminals (Gantry Cranes)

While technically classified separately, gantry cranes can be viewed as a variant of overhead cranes. Their bridge structure is supported by legs and travels along ground-level rails. They are widely used outdoors for container handling in ports and section assembly in shipyards.

6. Other Industrial Sectors

In industries such as papermaking, building materials, petrochemicals, and aerospace, overhead cranes are indispensable wherever heavy, bulky materials require movement.

Technical Specifications

(Custom configurations available upon request.)

Characteristics	Single Girder	Double Girder	Suspension
Structural Features	Single main girder with a relatively simple structure, featuring a crane trolley that travels beneath the girder.	Two main girders provide a robust structure, with the hoist trolley running between them for excellent stability.	The main beam is suspended beneath the building's roof structure and moves along the suspension track, saving floor space.
Lifting capacity	Suitable for lighter lifting tasks, typically ranging from 1 to 20 tons.	Suitable for heavy-duty lifting tasks, with lifting capacities typically exceeding 20 tons and reaching up to 500 tons or more.	Suitable for medium to light lifting tasks, typically ranging from 1 to 10 tons.
Job Level	A3-A5 (Medium-Light Load)	A5-A8 (Heavy-duty, intensive use)	A3-A4 (Light Duty)
Control Method	Ground control (handle operation), wireless remote control	Ground control, cab control, wireless remote control, variable frequency drive (VFD)	Ground exercises, wireless remote control
Advantages	Simple structure, low cost, easy installation and maintenance, with minimal height requirements for factory buildings.
