Description

Technical Field

[0001] This application relates to the field of rail vehicle technology, specifically to a lifting fixture for a brake caliper. Background Technology

[0002] Currently, in the field of rail vehicle technology, especially during the assembly of brake calipers for the 380D EMU, the brake calipers are transported using slings. First, the brake caliper is hoisted onto the assembly trolley platform. The overhead crane hook is then released from the sling. Next, the sling is passed through the center hole of the brake caliper mounting bracket on the frame. The overhead crane hook is then reattached to the sling, lifting the brake caliper onto the mounting surface. Bolts are inserted to secure the brake caliper. After confirming proper installation, the overhead crane hook is released, and the sling is removed. At present, the current hoisting tools and the entire operation process are cumbersome and time-consuming.
