The LDZ series electric single girder grab overhead crane is engineered for efficient material handling in industrial settings. It integrates a specialized grab spreader system—compatible with various attachments such as grabs, electronic suction cups, and lifting chains—to handle diverse materials with precision.
Constructed with a robust U-shaped steel plate design, the main girder is welded into a rigid box structure for enhanced durability. Paired with box-type end beams, the crane offers reliable longitudinal movement along elevated runway rails, allowing unobstructed lifting operations above ground-level obstacles. This structural configuration ensures high load-bearing capacity and consistent performance.
Key operational features include flexible control options: ground-based pendant control or cabin operation (available in open or enclosed models), with cabin placement adaptable to left or right sides based on facility layout. The crane’s entryway can also be customized to suit specific access requirements.
Core Components & Mechanism:
Structural Framework:
Comprising a welded box-section main girder and end beams, the crane structure is bolted for stability. Runway rails can be installed via welding, bolt fixing, or hook bolt methods to match site specifications.Travel System:
Equipped with independent trolley and crane travel mechanisms, both utilize soft-start squirrel cage motors with integrated disc brakes. Standard travel speeds range between 20-30 m/min for smooth and precise positioning.Hoisting Unit:
Features a conical rotor motor with high starting torque and a disc brake system, designed for repeated grab-based lifting cycles. The grab operates under light-duty cycling conditions, ensuring energy efficiency and operational reliability.Electrical System:
Powered by internationally recognized electrical components, the crane employs a multi-stage seamless conductor bar system for uninterrupted power transmission and minimal maintenance.
Ideal for applications requiring frequent grab-based transfers, the LDZ crane combines structural strength, adaptable control, and modular configuration to meet varied industrial demands.
The Single Girder Grab Overhead Crane delivers specialized material handling solutions across multiple sectors where efficient bulk material transfer is critical. Engineered for demanding industrial environments, this crane system excels in applications requiring frequent loading, unloading, and repositioning of loose or fragmented materials.
Bulk Material Management in Heavy Industries
From mining operations to cement production, this crane efficiently handles abrasive and heavy materials including coal, metallic ores, sand, and cement clinker. Its grab mechanism enables secure lifting and controlled placement of bulk commodities, streamlining processes from raw material intake to finished product dispatch in mineral processing and construction material facilities.
Recycling and Waste Management Operations
Scrap yards and recycling centers utilize the crane's versatile grabbing capability to sort, stack, and transport ferrous and non-ferrous scrap, demolished vehicle fragments, and industrial waste. The system significantly enhances operational safety by minimizing direct human contact with sharp or heavy recyclables while improving material throughput in recycling logistics.
Energy and Utility Sector Applications
Power generation plants deploying solid fuels—such as coal-fired stations and biomass energy facilities—rely on these cranes for continuous fuel handling. The grab attachment efficiently manages stockpile organization, boiler feeding operations, and ash removal, ensuring uninterrupted power generation while reducing manual handling in demanding thermal production environments.
Industrial Manufacturing and Production Support
Manufacturing plants with bulk material requirements—including foundries, metal fabrication shops, and compound processing units—integrate these cranes into their production workflows. The system seamlessly transfers raw materials between storage and processing areas, supporting just-in-time material supply to production lines and minimizing operational bottlenecks.
Port and Logistics Material Transfer
Inland ports, freight terminals, and bulk storage depots employ single girder grab cranes for rapid loading/unloading of commodities like grain, fertilizers, and aggregate materials from transport vehicles. The crane's longitudinal travel and precise grab control enable efficient material distribution across large storage areas, optimizing space utilization in logistics hubs.
Infrastructure and Construction Material Handling
Major construction projects and precast concrete factories utilize these cranes for aggregate handling, concrete component positioning, and site material organization. The equipment's ability to operate unimpeded above ground-level obstacles makes it ideal for managing construction materials in congested project sites while maintaining safety and workflow continuity.
By automating the handling of diverse bulk materials—from sand and coal to industrial by-products—the Single Girder Grab Overhead Crane delivers operational reliability, reduces labor costs, and enhances safety standards across these key sectors. Its adaptable design supports both stationary and mobile material management requirements in modern industrial operations.
