General purpose overhead crane
Weiyuan 20 Ton Double Girder Overhead Crane with Grab Bucket
Product Overview
The Weiyuan 20 Ton Double Girder Overhead Crane with Grab Bucket is engineered for bulk material handling and heavy-duty lifting. Equipped with an electric trolley-hoist and an optional 4-rope or hydraulic grab, it delivers precise, efficient loading/unloading of scrap, ore, clinker, biomass, and aggregates. The double-girder box structure ensures high rigidity and low deflection, while flexible controls (pendant, remote, cabin) adapt to diverse bays and safety needs.1
Product Advantages
- Bulk Handling Efficiency Purpose-built for grabs; stable lifting and smooth trolley/bridge travel improve cycle times and throughput.1
- Heavy-Duty Double-Girder Structure Rigid box-beam reduces sway and improves positioning with long-span coverage.1
- Configurable Grab Systems Supports 4-rope mechanical or hydraulic grabs sized to material density and bucket volume.1
- Reliable Power and Control 3-phase AC 380V/50Hz standard; pendant, wireless remote, or operator cabin control available.1
- Maintainability & Safety Modular assemblies, bolted interfaces, integrated overload and limit protections, and supplier test reports.1
Application Scenarios
- Scrap yards and steel mills: scrap handling and charge preparation
- Ports and terminals: bulk cargo loading/unloading
- Cement and aggregates: clinker, limestone, sand handling
- Biomass and energy: chips, pellets, feedstock transfer
- Waste and recycling plants: refuse-derived fuel and bulk sorting1
