Electric hoist can not overcome the weight stayed defects

  Speaking of hoist operation, mainly refers to the movement up and down, under normal circumstances is not stayed heavy, but the rail car hoist operations can overcome the defects can not be stayed heavy, following your brief:
Which mainly by  Hoist and trolley ,  lift hoist   etc., the main features are: electric hoist and trolley body length direction perpendicular to the direction of walking, lifting hoist and trolley to rotate back and forth between, can not overcome the general electric hoist heavy stayed defects.
        This section electric hoist can well meet the operational needs of the rail car operation to complete before the first cable-stayed rail or heavy lifting loading the working process, the electric rope hoist  easy to damage. So as to achieve the efficient and safe destination, but more importantly is to expand the field of application of electric Wire rope hoist  and scope.
