Double Girder EOT Crane

General Description of Double Girder EOT Crane

◆ Finding suitability in industry sectors like Pipe mills, Heavy engineering industries, Steel Furnace, Paper-Mills and others

◆ Provides for higher hook lift as hook can be pulled up between two main girders

◆ Used for lifting as well as meeting transporting needs of materials of any capacity/span

◆ Travel on parallel girder on fix column requiring heavy capacity and wide spans

◆ Can be offered in different ton capacities with desired span

◆ Can be made available in different lifting capacities

Product Item

◆ Structure: Main beam, End carriage, Hoist trolley, Complete electrical system and control system

◆ Quality Standard: ISO 9001:2000 ISO 14001:2004 and OHSAS 18001
◆ Motor: Slipring motors, dust proof construction foot
◆ Brakes: Independent Hydraulic Brake
◆ Gear Box: All gears & pinions running on antifriction type ball / roller bearings in totally enclosed oil bath giving constant splash lubrication
◆ Limit Switch: Safety limit switches for stoppers will be provided to prevent over traveling in all motions.

According to the difference of the lifting mechanism, we devide double girder EOT crane into two categorites:

1. Double girder EOT crane with electric hoist (traditional style and european style for choice)

It is composed by the main girder, end carriages, electric hoist with trolley, and electric control system. It is widely used in plants, warehouses or materials such as coil handling, container lift, railway workshop, paper mill and so on.


Traditional style		European style

2. Double girder EOT crane with open winch hoist (traditional style and european style for choice)

It is composed by the main girder, end carriages, open winch hoist with trolley, and electric control system.


Traditional style		European style

3. Double girder EOT crane lifting mechanism

Double girder EOT crane is a heavy lift equipment for general industry application. These type is more durable and reliable than single girder overhead crane. Duty class of double girder EOT crane with electric hoist is A3~A4 while this type can fit the low headroom very well. Double girder EOT crane with open winch hoist available more heavy loading capacity than double girder EOT crane with electric hoist.

4. European style double girder EOT crane have much advantages as below:

Compact Gear Motor

* Smooth traveling and lifting work,
* Low Dead Weight
* Low Noise
* German Quality, Safety and Durable

Limit Switch

* Safe Limit Switch for Lifting and Traveling
* Incase of load crash the top of lift mechanism
* Incase of trolley or Crane crash to the end of track.

Small and high strength Wheel

* Small euro-type wheel help lowen the whole dead weight of the overhead crane
* Advanced Wheel shape design lower the noise and make the traveling more smoothly

Aviation Revos

* With this Aviational Revos, the Electrical box has a higher protect class, Safety and Reliable

Hook

* DIN standard hook with block
* High strength and with cover, Beautiful and pratical

>> Advantages

◆ High long and cross-travel speeds thanks to high-performance overhead crane double girder design

◆ Low deadweight reduces investment layout

◆ Crane girders can be adapted to building structure requirements

◆ Minimum approach dimensions thanks to compact travelling hoist design

◆ Crane control to meet application requirements: via radio control, control pendant or cab control (optional)

◆ Maintenance platform and accessible crab facilitate maintenance of building interior fittings (optional)

◆ Improved load handling thanks to increased lifting and cross-travel speeds

◆ Low-sway load motions thanks to infinitely variable cross-travel speeds*

◆ Limit Switchs for Lift and CT equiped for safe lifting or traveling, avoid the Collision

◆ Overload Protection Device increase the security performance

◆ Remote Control* makes the Operation easier and more Convenient

◆ Double speed for all machnism* provide a good choice for precise work

◆ Voltage lower protection function Phase sequence protection function

◆ Emergency stop function

◆ Rain cover for outside hoist, driving units, electrical cubicle.

◆ Warning indicator: flashing lights and warning sound.
