Design Parts of the Double Girder EOT Cranes and their applications:

  • Design: The design of these cranes comes with compact dimensions and a low weight. They are easy to use, maintain and handle. The design is of the modular type which can be easily installed between components.
  • Motors: These cranes are equipped with cylindrical rotor motors and are made with aluminium sections. They have built-in safety brakes of class F insulation and IP54 protection.
  • Gearboxes: The gearbox is of the flat helical type. They are made with light alloys and case-hardened gears. They also have quality surface treatment and are equipped with permanent lubrication.
  • Brakes: The brakes have a dual-disc electromagnetic design. They come with the feature of automatic operation in the case of power failure. These breaks are staunch and can withstand up to 1 million braking operations.
  • Electrical Panel: The electric panels have a modular design and encompass and a wide operation range. They are easy to install and require minimal maintenance and are thus reliable. They also provide fuse-less circuitry. An overload protection device with a motor is used to secure each drive group from severe overloading.
  • Painting: All the parts are painted with two layers of primer before the process of assembling. They are finished off with two layers of enamel after the testing process is done.
  • Limit Switches: The cranes have staunch limit switches which prevent the situations of over hoisting and also ensure that over lowering of hooks also doesn’t take place.
  • Push Button Stations: They are made using quality aluminium. They come with easy operation methodology and are very light in weight.
  • Soft Starts: They are electrically linked with the long travel drives. They ensure that the cranes have a seamless jerk-free start.
  • Maintenance Platform with Hand Railing: They ensure quick and convenient maintenance of the crane and are spread along the length of the girder.
  • Buffers: The buffers are fabricated using rubber (natural, Nitrile, Neoprene, etc. based on client requirements) and come in a lot of different shapes and sizes. They are helpful for vibration controls and also for damping.
  • Camber: The neutralise the extra heavy weight of the loads and protect the crane from damage.
  • Crane Cabin Operated: Operators in cabs are used to control cranes and are connected to bridges and trolleys.
  • Bumper (Buffer): They helps nullify the harmful impacts on the crane after it crosses its permitted travel limit. Buffers dissipate energy while bumpers absorb energy for doing the same They are usually attached to trolleys and bridges.
  • Bridge: Bridges are in the shape of vertical plates and are installed between girders. They support the structure and help the coordination of the wheels on the rail.
  • Diaphragm: The diaphragm also works like a bridge and makes the crane structure sturdier by supporting it.
  • Deflection (Live Load): It is the shift caused in the bridge girder position in the vertical plane. It is caused by the trolley weight.
  • Dead Load: It is the weight of the steel crane which move along the crane runway girder.
  • Longitudinal Travel Motion: It is the cumulative motion of the crane on its tracks.
  • Span: It is measured by the centre-to-centre distance between two runway rails.
  • Wheelbase: It is measured as the centre-to-centre distance of the last wheels of a trolley when parallel to the axis of the rail.
