Three Major Differences Between Overhead Cranes And Gantry Cranes
Three Major Differences Between Overhead Cranes And Gantry Cranes
Rated lifting capacity greater than or equal to 0.5t lifts, rated lifting capacity greater than or equal to 3t, and lifting height greater than or equal to 2m cranes belong to special equipment. No direct relationship with the lifting machine weight.
According to the AQSIQ on the revision of the "special equipment catalogue" announcement (No. 114 of 2014) attached to the special equipment catalogue.
Special equipment described in the lifting equipment (machinery): refers to the vertical lift or vertical lift and horizontal movement of heavy mechanical and electrical equipment.
The scope of the provisions of the rated lifting capacity greater than or equal to 0.5t lifts; rated lifting capacity greater than or equal to 3t (or rated lifting moment greater than or equal to 40t - m tower cranes, or productivity greater than or equal to 300t / h of the loading and unloading bridges), and lifting height of greater than or equal to 2m of the crane; number of floors is greater than or equal to the 2-storey mechanical parking equipment.
Bridge crane and gantry crane similarities and differences in addition to the appearance of the different roles. Their similarities and differences are as follows:
Difference one:
Bridge cranes are lifting equipment for lifting materials across workshops, warehouses and yards.
2. Gantry crane is a deformation of the bridge crane, also known as gantry crane. Mainly used for outdoor loading and unloading operations in the yard, yard goods, bulk cargo.
Difference two:
The bridge crane is shaped like a bridge because its ends are located on tall concrete columns or metal supports.
Gantry crane metal structure like a door-shaped frame, bearing the main beam under the installation of two feet, you can walk directly on the ground on the track, the main beam at both ends can have an outreach cantilever beam.
Difference three:
The bridge crane's bridge runs longitudinally along the track laid on both sides of the overhead, which can make full use of the space under the bridge to lift materials without being hindered by the ground equipment. It is the most widely used and most numerous type of lifting machinery.
Gantry cranes have the characteristics of high site utilisation, large operating range, wide adaptability and strong versatility, and are widely used in port cargo yards.
