This document discusses different types of overhead cranes called EOT cranes. It describes single girder EOT cranes that can lift up to 20 tons and have a span of up to 40 meters, and double girder EOT cranes that can lift up to 200 tons and have a span of up to 65 meters. The main difference between single and double girder cranes is the hook height, which is typically 18-36 inches higher for double girder cranes. Some common causes of crane failure are also listed, including electrocution, crushing during assembly/disassembly, failure of the boom or cable, crane tip over, and falls.

1. Eot Cranes Types And Their Usages

2. INTRODUCTION
A Crane is a type of machine, generally equipped with a hoist, wire ropes
or chains, and sheaves, that can be used both to lift and lower materials
and to move them horizontally. It uses one or more simple to create
mechanical advantage and thus move loads beyond the normal
capability of a human.
An overhead crane, commonly called a bridge crane, is a type of crane
found in industrial environments. An overhead crane consists of parallel
runways with a traveling bridge spanning the gap.

3. Types of Eot Cranes

4. SINGLE GIRDER EOT CRANES
Capacity: Up to 20 Ton
Span: Up to 40 m
Speeds:
Hoisting : Up to 10m/min
Cross Travel :Up to 35m/min
Long Travel :Up to 65m/min
Micro Speed :10% of all motions
Custom Speeds are also avilable for all motions.

5. DOUBLE GIRDER EOT CRANES
Capacity: Up to 200 Ton
Span: Up to 65 m
Speeds:
Hoisting : Up to 15m/min
Cross Travel :Up to 35m/min
Long Travel :Up to 65m/min
Micro Speed :10% of all motions
Custom Speeds are also avilable for all motions.

6. Diffrence Between Single and Double Girder Cranes
The real difference between single and double girder cranes is
hook height (how far above the floor your hoist will lift). Double
girder cranes provide better hook height, typically 18-36 inches
better.
Double girder cranes can provider more lift, because on double
girder cranes the hoist is placed between the cross girders, not
under the cross girder. You gain the depth of the cross girder.

7. CAUSES OF CRANE FAILURE
The Main Cause of crane failure are listed as:
Electrocution
Crushed During Assembly / Disassembly
Failure of Boom / Cable
Crane Tip Over
Struck By Cab / Counterweight
Falls
