Single Girder EOT Crane

Our single girder EOT cranes offer the following benefits:

• Minimum load on building structure and crane runway
• Maximum hook approach
• Great mobility and transportation capabilities to promise safe handling
• Cost-efficient operations owing to optimal space utilization
• High stability even for low dead weights
• Strength to handle loads 1 Ton to 20 Tons
• Maximum reach owing to a span of 5-25 meters

Special Features of modular cranes :

• Light Weight and compact construction minimizing building loads and space saving
• Suitable for Light and Medium duty workshop applications
• All motors are TEFC with class F insulation
• Heavy duty cast steel rope guide
• Upper and Lower hook travel limit switch
• Additional Counter weight operated over hoist limit switch as option
• VVVF drives are available as an option
• Compact and lightweight festoon cable system
• Pendent and Radio remote control operation

Ranges from 1 to 20 Tons, in either Box / Beam profiles, fitted with hand operated trolleys or electric trolley to suit specific customer requirements. A choice of VFD contractor control is offered as optional variants. Control is generally through Pendant & REMOTE CONTROL through Radio Remote can be offered.

Single Girder Cranes up to 25 meters span can be manufactured. Hoists can be either Wire rope hoists or Electric Chain hoists depending on specific application & safe working loads. Long travel mechanisms are equipped with Helical Geared Motor & VFD as standard features.

The EOT Crane moves over the rails placed on the top of crane runway or Gantry Girders. The crane mainly comprise of bridge girder made from rolled sections such as I beams / U beams or fabricated box section. The bridge girder is supported on two end carriages, each housing a pair of wheels. The wheels are driven by motor gearbox units. A wire rope hoist is suspended below the bridge girder. The crane can be operated through pendent station hanging from wire rope hoist or through radio remote control. The pendent station can be made to move independent of hoist movement as per customer's choice.

The wire rope hoist comprise of rope drum made from seamless tube. Grooves are machined on rope drum for proper support to the wire rope. Cast Iron rope band and guide prevents wire rope jumping from grooves. The hoisting drive arrangement comprises of motor coupled to an oil lubricated, spur / helical gearbox that in turn provides the motion to the rope drum. An electromagnetic fail safe brake prevents accidental lowering of load in the event of power failure. Limit switch is provided to prevent over hoisting of hook block. Additional limit switch can also be provided to prevent over lowering of hook block.

The cross movement of hoist is achieved through the movement of wheels supported on the beam / box flange. The drive to the wheels is provided through an electric motor-gearbox unit. Fail safe brake and limit switch are provided as additional features is so desired by customer.

Power supply to the wire rope hoist is through festoon cable system. The flexible cables are supported by cable hanger or cable trolleys that move on either taught wire or enclosed C track depending on customer choice.

The single girder cranes find their application mainly for capacities up to 20 MT and Span up to 25 Meters. These are commonly used for light and medium workshop duty applications. However, in rare cases the single girder cranes are also used for hot metal ladle handling as well as with grab bucket.
