Several crane introduce rehabilitation programs

General  overhead gantry crane  for its large carrying capacity, good stability and a series of advantages are widely used in various types of workshops, factories and warehouses. However, the lack of impact of headspace height of overhead cranes, double girder bridge crane particularly important reason to use one. The workshop or factory roof reconstruction is very difficult work; re-build the crane bearing rail beam is put too much, so by the traditional general-purpose  overhead bridge crane  structural transformation, reduce machine height, is the most viable solution to this problem methods.

Crane design principles explicitly mentioned in the three basic conditions:

Cranes and mechanical parts metal structure should have sufficient strength, stiffness and resistance to buckling;

Machine must have the necessary stability against overturning;

Prime mover has to meet the requirements of the job performance power brakes provide the necessary braking torque.hoist gantry crane During crane structural transformation, they must meet three basic conditions. Traditional designs were analyzed and found the car above the rail height is the height of the main factors affecting the whole world.

Through its orbit for small frame transformation can reduce machine height. Small frame metal structure change this transformation program will be the biggest feature is the horizontal support surface placed in the car, under the car axle instead of the traditional design will be placed on the supporting surface on top of the car axle. Rack mounted in the car lifting mechanism and other components "hidden" in between the two main beams and shelves trolley car parts below the highest point of the axle.


General overhead crane technology is mature, highlight the advantages. But according to the traditional design of a large crane machine height, in some special occasions can not install and use. Through the transformation of the trolley bridge crane structure can reduce the overall height of the overhead crane applications enhance the breadth. Above describes several rehabilitation programs, and in the actual production in the applications.
