ABSTRACT OF THE DISCLOSURE An improved self-locking scaffold bracket employ- ing a load activated lock in combination with a foot operated hoisting device which may be hoisted without lost motion relative to the support. The scaffold bracket utilizes a rigid frame directly supported upon a lock which clamps to an upright post. The scaffold can be raised by a hoisting device of the block and tackle type or by a foot operated hoisting mechanism of the type which "walks" up the post. The hoisting device engages the lock in a manner causing the lifting force to be exerted at a trunnion axis of the lock which is so situated that it eliminates lost motion and tilting during the hoisting operation.
