Abstract: A system for providing reinforcement to structures comprises a prefabricated rebar assembly, a first end plate and a second end plate. The prefabricated rebar assembly comprises multiple rods connected to each other. The prefabricated rebar assembly is held between the first end plate and the second end plate to form a block of rebar assembly.

Abstract: A lifting device detachably interconnecting a lifting machine to a lug is disclosed, comprising a body having a longitudinal axis and a throughpassage having an axis transverse thereto, which throughpassage extends between first and second lateral sides of the body; a shackle connecting the body to the lifting machine; a lift pin having a head, a shaft extending therefrom along a major axis to an end, a bore extending through the shaft adjacent the end, substantially normal to the major axis, the shaft being insertable into the throughpassage to a fully inserted position, whereat a terminal section of the shaft containing the end and the bore projects from the first lateral side with the bore substantially vertical, the head projects from the second lateral side, and an intermediate section of the shaft between the terminal section and the head is positioned to provide lifting engagement of the lug; a stop pin having a head and a shaft extending from the head which is, when the lift pin is fully inserted, ins
