Single Girder EOT Crane: Types, Specifications, Prices & Manufacturer Guide
Introduction
Single girder Electric Overhead Traveling (EOT) cranes are essential for material handling in industries like manufacturing, warehouses, and construction. Dongqi Crane, a leading single girder EOT crane manufacturer, offers a range of models from 1 ton to 20 tons, catering to diverse lifting needs.
This guide compares single girder vs. double girder EOT cranes, analyzes LD-type and LDP-type designs, lists specifications and prices, and explains key parts and suppliers for informed purchasing decisions.
1. Types of Single Girder EOT Cranes
Single girder EOT cranes are categorized based on design standards, structural configurations, and application requirements. Below is a detailed comparison of the most common types available from Dongqi Crane, along with their key features and industrial applications.
Comparison Table of Single Girder EOT Crane Types
| Type | Capacity Range | Span Range (m) | Lifting Speed (m/min) | Key Features | Best Applications |
|---|---|---|---|---|---|
| LD-Type | 1–20 tons | 5–22.5 | 8/20 (Hoist/Trolley) | - Standard I-beam construction - Hook or grab bucket compatible - Cost-effective for medium-duty use | - Manufacturing workshops - Warehouses - Assembly lines |
| LDP-Type | 1–10 tons | 5–16 | 8/20 (Hoist/Trolley) | - Low headroom design - Lightweight structure - Reduced wheel load | - Small factories with height restrictions - Production lines with limited space |
| European Standard | 1–16 tons | 5–25 | 3.8–20 (VFD adjustable) | - Compact and energy-efficient - Smooth operation with VFD control - High precision positioning | - Automotive industry - Food processing plants - High-precision manufacturing |
Detailed Analysis of Each Type
LD-Type Single Girder EOT Crane
Structure: Uses a single I-beam or box girder for the main bridge, supported by end carriages with forged steel wheels.
Hoist System: Typically equipped with CD/MD-type electric wire rope hoists for vertical lifting.
Advantages:
Lower initial cost compared to double girder cranes.
Simple maintenance due to fewer moving parts.
Suitable for general material handling in workshops and storage facilities.
Limitations:
Not ideal for very heavy loads (>20 tons) or long spans (>22.5m).
LDP-Type Single Girder EOT Crane
Structure: Features a lightweight girder with optimized headroom, making it ideal for facilities with low ceilings.
Hoist System: Uses a low-profile hoist to maximize lifting height in constrained spaces.
Advantages:
Space-saving design (ideal for facilities with height restrictions).
Lower wheel load reduces runway beam requirements.
Limitations:
Lower capacity (max 10 tons) compared to LD-type.
European Standard Single Girder EOT Crane
Structure: Built with welded box girders for higher rigidity and precision.
Hoist System: Integrated with variable frequency drives (VFD) for smooth acceleration/deceleration.
Advantages:
Energy-saving operation (up to 30% less power consumption).
Anti-sway control for precise load positioning.
Limitations:
Higher cost due to advanced features.
Which Type Should You Choose?
For general industrial use (1–20 tons): LD-Type (most cost-effective).
For low headroom facilities (1–10 tons): LDP-Type (space-optimized).
For high-precision, frequent operations (1–16 tons): European Standard (premium performance).

2. Single Girder vs. Double Girder EOT Crane
| Feature | Single Girder | Double Girder |
|---|---|---|
| Cost | Lower (¥15,000–¥150,000) | Higher (¥50,000–¥300,000) |
| Lifting Capacity | Up to 20 tons | Up to 500+ tons |
| Span Range | 5–22.5m | 10–35m+ |
| Headroom | Compact | Requires more space |
| Maintenance | Easier | More complex |
| Best For | Small workshops, light loads | Heavy industries, steel plants |
✔ Choose Single Girder If:
Budget is limited.
Lifting needs are ≤20 tons.
Facility has low ceiling height.
✔ Choose Double Girder If:
Handling >20 tons.
Long-span requirements (>22.5m).
High-duty cycle (e.g., steel mills).

| Model | Capacity | Span (m) | Lifting Height (m) | Motor Power (kW) | Price (RMB) |
|---|---|---|---|---|---|
| DQ-LD-1T | 1 ton | 5-10 | 6-18 | 2.2 | ¥15,000–¥25,000 |
| DQ-LD-2T | 2 tons | 5-12 | 6-18 | 3.0 | ¥18,000–¥30,000 |
| DQ-LD-3T | 3 tons | 5-15 | 6-18 | 4.5 | ¥22,000–¥35,000 |
| DQ-LD-5T | 5 tons | 5-18 | 6-18 | 7.5 | ¥35,000–¥55,000 |
| DQ-LD-10T | 10 tons | 10-22.5 | 6-24 | 13.0 | ¥65,000–¥100,000 |
| DQ-LD-20T | 20 tons | 12-22.5 | 6-24 | 22.0 | ¥120,000–¥150,000 |
Notes:
Prices vary based on span, lifting height, and optional features (VFD, remote control).
LDP models cost 10-15% less due to simplified structure.
