EOT Cranes, Single Girder

Cranoist Material Handling Equipments designs and manufactures single girder Electric Overhead Travelling (EOT) Cranes. These conform to IS 807, IS 3177 codes of practice for design, manufacturing, erection, testing of structural parts; and to IS 3177 code of practice for design of overhead travelling cranes. In the design of components adequate factors of safety as per relevant code is allowed. Impact, fatigue, wear and stress concentration factors are taken care of whenever applicable. All drives are designed to give sound and efficient performance. Steel construction: structural steels are used in the manufacturing of cranes, conforming to IS 2062 or equivalent. The bridge girder is fabricated from RSJ/box type construction. The maximum deflection of the bridge girder is limited to span/1000 of the live loads. Bridge girder is designed to sustain stresses created due to vertical and lateral forces with impact. End carriages are fabricated from rolled steel sections/plates with adequate diaphragms and stiffeners to give a rigid construction. The girders with gusset plates are set on the end carriages joined with bolts in rimmed holes. Rubber buffers are provided on both sides of end carriages for absorbing the jerks. Twin drive arrangements will be provided for LT motion, central drive arrangement also available on request. The motors used are special crane duty type, suitable for frequent starting, reversing and braking in accordance with IS 225. All trolley and drive motors have suitable AC/DC/ brakes as standard equipment with smooth running properties. Optional features include: micro speed arrangement through frequency inverters/variable frequency drives; cable festooned system or shrouded bus bar system; warning horn; bridge lights; and cabin operated through master controller.
