Gantry Type Multiple Girder Electric Overhead Travelling Crane

Gantry Type Multiple Girder Electric Overhead Travelling Crane

Gantry Type Multiple Girder Electric Overhead Travelling Crane design,production and inspection carry out the last issued relevant national standard, equivalently adopts some foreign criteria including FEM, DIN and IEC. Compared with the general QD type bridge crane, its weight is reduced by about 15~30%, the maximum wheel pressure is reduced by about 10~35%, which can the requirements of crane for factory building structure and reduce production cost. As the core component of driving mechanism, reducer gear pair with hard tooth surface and high precision gear set, forged wheel and variable-frequency speed regulating system, which makes this type of crane become renewal product of traditional general bridge crane and applied in industry of machinery production, assembling, petrochemicals, warehouse logistics, electric power construction, papermaking and railways.
