Abstract

An I-beam clamp comprises a body having a seat and defining a medial plane extending through and perpendicular to the seat and a normal plane aligned with the seat; a pair of pads mounted to the body for movement between respective closed positions beyond the seat, on opposite sides of and in spaced relation to the medial plane and in spaced relation to the normal plane, and open positions, whereat each pad is disposed, relative to its closed position, in a direction away from both the normal plane and the medial plane; and an actuator for effecting movement of the pads between their closed positions and their open positions. Clamp pairs can be secured to a disabled trailer undercarriage and a brace can be disposed between each pair. A saddle can be secured to each pair to urge the brace towards the undercarriage and support same for towing.

Dependent claims

In a disabled box trailer of the type having an exposed undercarriage comprising

a plurality of laterally-extending I beam cross-members spaced-apart from one another in substantially side-by-side parallel relation, each cross-member having
a first flange, a second flange spaced beneath and parallel to the first flange and
a central web extending between and connecting the first flange and the second flange, said plurality of I-beam cross-members comprising a first grouping of I-beam cross-members collectively defining a first plane and a second grouping of I-beam cross-members collectively defining a second plane disposed in angular relation to the first plane, a bracing system comprising;
a brace member disposed beneath and spanning between at least two of the cross-members of the first grouping and at least one of the cross-members of the second grouping and arranged substantially transversely to these cross-members;
a clamping assembly for each of said at least two cross-members of the first grouping and associated therewith and for-each of said at least one cross-member of the second grouping and associated therewith, each clamping assembly being selectively, releasably connected to its respective cross-member;
and
connection means selectively, releasably connecting the brace member to each clamping assembly to support said undercarriage as against sagging, for subsequent towing.
