摘要

The ends of two rails (1a,1b) are butted together (S). The upper (2) and lower (4) flanges have U-section grooves accommodating top clamping members (7-9) and lower clamping members (28,29). Wheels for a trolley run on the upper surfaces (3) of the lower flange. The clamping members pivot on a pin (16) in an eye (10) suspended from a pin (19) in a bore (18) in a double beam (11) with support pins (12) at its ends.
