Double Girder EOT Cranes

Unique Features

  • Structure - 100% Radiography of all butt welding joints of bridge and carriage to ensure defect-free welding and strong and rigid structure. the material of construction conforms top IS:226 or IS:2062,and the bridge is designed

  •  

  • Wheel Assemblies - Trolley and crane wheels are straight treaded double flanged forged steel wheels. heat treated to achieve a depth of 15-20 mm from the surface and gradually diminishing towards the center retainingthe core properties. these wheels are supported on antifriction ball/roller bearings.

  •  

  • Gearing-The gear reducers are constructed either in double, triple and quadruple reduction using regged wide faced helical and spur gears that are precision cut from special alloy steel forgings and to supported between two antifriction ball/roller bearings. All gear uniot are totally enclosed with oil bath splash lubrication.

  •  

  • Crane Micro Drives- The spacial micro drive provides fine inches movements of hoest, trolley or crane at the rate of 5% to 20% of the rate of the main speed. The micro drive achieved by a separate gear box with unique sun and plant system gearing system fitted on the input side of main gear unit it is a positive drive and avoid the use of clutches etc. (Optional)

  •  

     
  • VVVF Drives- Variable frequency controlled electronic ac drives are available for infinite variable control of speed it saves power consumed by cranes and improve load maneuvering.(optional)

  •  
     

     


     

  • Crane Drives-We offer a wide selection of A.C. control packages to meet your electrical requirement. we select only the best standard crane and hoist duty motors and all electrical components and accessories from the nation’s leading manufacturers to ensure dependable driving power.
