These devices are often large in size and heavy in weight, requiring high safety, efficiency and professionalism during handling. Before handling, the first task is to conduct a comprehensive assessment of the large equipment to be handled, including detailed recording of information such as device size, weight, material, structural characteristics and vulnerable parts.

[0003] It should be noted that during handling, two traction transfer trolleys and two follow-up transfer trolleys form a traction base, and two L-shaped frames on the two traction transfer trolleys and two follow-up transfer trolleys are combined and adjusted according to the size of the large equipment.
