Product DescriptionNew 1 Ton Single Girder Overhead Crane 20m Lifting Height Construction Manufacturing Plants Featuring Motor Engine 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.SpecificationTechnological Evolution and Drive ControlModern 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 ParametersCore 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.right elevationleft elevationfront elevationPrimary ApplicationsOverhead cranes find extensive use across virtually all industrial settings requiring vertical and horizontal handling of heavy materials.1. Manufacturing and Assembly WorkshopsIn 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 MetallurgyThis 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 CentersUsed 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 EnergyIn 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 SectorsIn 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.)CharacteristicsSingle GirderDouble GirderSuspensionStructural FeaturesSingle 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 capacitySuitable 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 LevelA3-A5 (Medium-Light Load)A5-A8 (Heavy-duty, intensive use)A3-A4 (Light Duty)Control MethodGround control (handle operation), wireless remote controlGround control, cab control, wireless remote control, variable frequency drive (VFD)Ground exercises, wireless remote controlAdvantagesSimple structure, low cost, easy installation and maintenance, with minimal height requirements for factory buildings.Exceptional stability, high lifting height, strong load capacity, smooth operation, suitable for heavy-duty tasks.No ground tracks required, saving space and offering flexible installation to accommodate low-ceilinged factories.Typical ApplicationsMaterial loading, unloading, and handling for small and medium-sized factories and warehouses.Heavy material handling for large factories, steel and metallurgical plants, power stations, ports, and terminalsLight-duty workshops, warehouses, and locations with specific floor space requirements.Drawings & DimensionsDetailed CAD drawings and dimensional diagrams are available for download here or upon inquiry. Our engineering team can provide tailored designs to meet specific project requirements.After Sales ServiceStandard Warranty: 12 months or 2,000 operating hours (whichever comes first).Extended Warranty: Optional coverage up to 36 months.Global Support: 24/7 technical assistance and spare parts supply.Training: On-site or remote operation/maintenance training.Company ProfileTai'an Chuangdong New Material Technology Co., Ltd.
