Single Girder EOT Crane: The Short Answer
A single girder EOT (Electric Overhead Travelling) crane has one bridge girder that runs on rails along your shop walls, with a hoist that travels along the girder. It lifts, carries and places loads anywhere over the floor while keeping the floor free for work. For most workshops, warehouses and maintenance bays, it is the most economical overhead crane for light to medium duty.
WSP Cranes & Services builds single girder EOT cranes at our Pune works and supplies them across India for manufacturing plants, engineering workshops, fabrication units, warehouses and other industrial sites. Every crane is sized for your building, load, span, lifting height and working hours.
What Is a Single Girder EOT Crane and How Does It Work?
The bridge is one main girder supported by two end carriages that travel on runway rails. The hoist and trolley move along the girder. Three movements work together to place a load exactly where you need it:
- Hoisting: raises and lowers the load.
- Cross Travel (CT): moves the hoist along the girder.
- Long Travel (LT): moves the whole crane along the runway.
Because the bridge is lighter than a double girder crane, it puts less load on your building columns and runway. That often makes it easier and cheaper to install, provided the load, span and duty suit a single girder design.
Single Girder EOT Crane Technical Specifications
| Parameter | Technical Specification |
|---|---|
| Capacity | 250 kg – 20 Ton |
| Span | Up to 50 m |
| Height of Lift (HOL) | Up to 30 m |
| Design Standards | IS 3177 / IS 807 |
| Crane Type | Single Girder EOT |
| Operation | Pendant / Radio Remote / Combined Mode |
| Drive Control | VFD-controlled Hoist / CT / LT |
| Power Feeding | Shrouded DSL / Festoon System |
The final configuration depends on your load, duty, building, runway and site conditions.
Which Capacity Do You Need? 1, 2, 5, 10 or 20 Ton
Most buyers start with tonnage, so here is a practical guide. These are typical uses, not fixed rules. Span and duty also matter.
| Capacity | Typically Used For |
|---|---|
| Up to 3 Ton | Assembly lines, tool rooms, maintenance bays, light machining, packing and dispatch |
| 5 Ton | Machine shops, fabrication units, motor and pump handling, general warehouses |
| 10 Ton | Heavier fabrication, die and mould handling, workshops moving large assemblies |
| 15 – 20 Ton | Heavy components. Check span and duty carefully, as a double girder EOT crane may suit better |
Always size the crane for the heaviest load plus the lifting beam or attachment, not the material weight alone.
Single Girder EOT Crane Price: What Decides the Cost
Buyers often ask for a price per ton, but two 5 ton cranes can cost very differently. The price mainly depends on:
- Capacity and span: a longer span needs a stronger, heavier girder.
- Height of lift: more lift means more wire rope and a larger drum.
- Duty class: a crane used all day needs a heavier-duty hoist, motors and brakes than one used a few times a day.
- Hoist type: standard or premium branded wire rope hoist.
- Drives and controls: VFD and radio remote add cost but improve control and safety.
- Power feeding and site conditions: DSL or festoon, indoor or outdoor use, and whether runway beams already exist.

Key Features of WSP Single Girder EOT Cranes
1. Optimized Girder Design
The girder is designed for the required strength with controlled deflection, using rolled or fabricated sections depending on your span and load. A well-designed girder keeps the trolley moving smoothly and gives the crane a long working life.
2. High-Duty Hoisting System
The hoist is selected for your lifting capacity, lifting height and duty cycle. WSP uses Carl Stahl Craftsman wire rope hoists in high-duty configurations aligned with applicable FEM/ISO classifications. See our electric wire rope hoists and trolleys and crabs.
3. VFD-Controlled Drive System
Variable Frequency Drives control hoisting, cross travel and long travel. This gives gentle starts and stops, less load swing and more precise positioning, and it reduces mechanical shock on the crane.
4. Precision-Machined End Carriages
Machined end carriages and hardened travel wheels support smooth long-travel movement and reduce wear on wheels and rails.
5. Helical/Hardened Gearbox
Helical or hardened gearboxes deliver reliable torque for starting and moving the crane while keeping operating noise low.
6. Fail-Safe Braking System
Fail-safe electromagnetic or electro-hydraulic brakes stop each movement when needed. Brakes are selected for the mechanism, load, speed and duty.
7. Flexible Control Options
You can operate the crane with:
- Pendant control
- Radio remote control
- Combined pendant and radio remote operation
Radio remote keeps the operator at a safe distance with a clear view of the load. A pendant is simple and economical for smaller bays.
8. Reliable Power Feeding
Power reaches the moving crane through a shrouded DSL system or a festoon system, chosen to suit your runway and site.
Major Components of a Single Girder EOT Crane
- Main Girder
- The main bridge structure. It carries the hoist trolley and passes the load to the end carriages.
- End Carriages
- Fitted at both ends of the girder. They hold the travel wheels and long-travel drive.
- Hoist and Trolley
- The hoist lifts and lowers. The trolley carries it along the girder.
- Wire Rope and Hook Assembly
- Connects the hoist to the load through the hook block.
- Long-Travel and Cross-Travel Mechanisms
- Motors, gearboxes and wheels that move the whole crane along the runway (LT) and the hoist along the girder (CT).
- Brakes
- Control and stop each crane movement.
- Control Panel and Power Feeding
- The panel holds the control and protection gear. Shrouded DSL or festoon supplies power to the moving crane.
- Operator Controls
- Pendant station, radio remote, or a combined system.

- VFD drives give gentle acceleration and deceleration for safer load positioning.
- Easy Maintenance
- Accessible components make routine inspection and servicing simpler.
Single Girder vs Double Girder EOT Crane
Choose by capacity, span, lifting height, duty, headroom and site conditions. Not by capacity alone.
| Factor | Single Girder EOT Crane | Double Girder EOT Crane |
|---|---|---|
| Main Bridge | One main girder | Two main girders |
| Best For | Light to medium duty | Heavy loads and continuous duty |
| Weight on Building | Generally lower | Generally higher |
| Hook Height | Good with a low-headroom hoist | Higher, as the hook lifts between the girders |
| Extras (Cabin, Walkway, Second Hoist) | Limited | Easy to add |
| Cost | Lower upfront | Higher |
