EOT Crane Buying Guide: Single Girder vs Double Girder and How to Choose

One wrong choice between a single girder and a double girder crane can cost you headroom, budget and years of smooth operation. Getting this decision right matters more than any other point on the specification sheet.

What Is an EOT Crane?

EOT stands for Electric Overhead Travelling crane. It runs on rails fixed high along the sides of a workshop and lifts loads with an electric hoist. The crane moves in three directions: long travel (along the shed), cross travel (across the bridge) and hoisting (up and down). It is the backbone of material handling in steel plants, fabrication shops, warehouses, power plants and machine shops.

Main Parts of an EOT Crane

• Bridge girder(s) that span the shed width
• End carriages with wheels that run on the rails
• Hoist and trolley for lifting and cross travel
• Wire rope, hook and limit switches
• Control system (pendant, remote or cabin)

Single Girder vs Double Girder

A single girder crane has one bridge beam with the hoist hanging below it. It is lighter, costs less and suits light to medium loads. A double girder crane has two beams with the trolley running on top. It handles heavier loads, gives higher hook lift and suits long spans and heavy-duty work.

Choose single girder for general workshops and moderate loads. Choose double girder for heavy capacity, tall lifts or non-stop production.

What to Decide Before You Order

1. Capacity: the heaviest load you will lift, with some margin for the future.
2. Span: the distance between the two runway rails.
3. Height of lift: how high the hook must travel.
4. Duty class: how many hours and cycles per day the crane will work.
5. Controls: pendant, wireless remote or cabin operation.
6. Shed conditions: available headroom, runway length, power supply and any heat or dust.

Safety and Maintenance

Cranes must be built to relevant Indian standards, such as IS 3177 for EOT cranes, and checked by a competent person before use. Inspect wire ropes, hooks, brakes and limit switches regularly, and never lift beyond the rated load. Regular servicing prevents breakdowns and protects your people.
