Abstract
An overload brake and method for trolley suspended on a flange of a load traveling apparatus girder prevents the displacement movement of a suspended load along a girder by clamping a brake between two symmetrical flange tabs of the girder. The girder is elastically deformed by the load which is applied to the girder by the contact between a surface of the girder and translation wheels that move the load along the girder. Upon sufficient elastic deformation, portions of the girder contact a brake to prevent movement of the load along the girder.
Claims10
An overload brake for trolley, characterized by using local α angular elastic deformation of the girder loaded flange to block the trolley displacement movement along the girder by compressing a brake between two symmetrical tabs of the girder loaded flange.
An overload brake for a trolley, comprising:
- at least one wheel adapted to ride on a support member;
- and
- a brake member, wherein an overload condition is transmitted to the support member by the at least one wheel, causing angular deformation of the support member to press a portion of the support member into the brake member, thereby braking against translation movement along the support member.
A method for providing an overload brake for a trolley, comprising:
- providing at least one wheel adapted to ride on a support member;
- and
- providing a brake member, wherein an overload condition is transmitted to the support member by the at least one wheel, causing angular deformation of the support member to press a portion of the support member into the brake member, thereby braking against translation movement along the support member.
