DEVICE FOR JOINING CRANE-RUNWAY STRUCTURE WITH COLUMN Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: device relates to metal crane-runway structure with heavy-duty operation. Device has crane-runway girders 3 which carry three-head rail 1, brake girders 12 with horizontal plate, supports of crane-runway girder which are horizontally connected by studs 11 with column. Horizontal plate converts at right into channel bar 13 which is located between upper girth of crane-runway girder and longitudinal rib 5 created by bending of web of crane-runway girder. Located at left is channel bar which is attached to column by hinge 15 symmetrically to channel 13. Clearance between lower girth of girder and plate of column step is equal to 2-3 thicknesses of lower girth of crane-runway girder. Symmetrical shock absorbers 9 are used as supports of crane-runway girder. Application of aforesaid embodiment of device allows for reducing metal-input together with prolonging service life. EFFECT: higher efficiency. 2 dwg
