The Joe Wagner Group is a family-founded civil construction and plant hire company. Headquartered in Toowoomba, Queensland, with an additional office in Brisbane, the business has been operating since 1985. It partners with public and private sector clients—including all levels of government, commercial entities, and the energy and rail industries—to deliver major infrastructure projects across Queensland and Northern New South Wales.

The PRM Engineering Services Sentinel SIL-Rated Height and Slew Limiter is an advanced safety technology designed to prevent heavy machinery—such as excavators, loaders, skid steers, and backhoes—from striking overhead hazards or rotating into unsafe zones. Developed and manufactured in Australia, the Sentinel Safety system can be configured for height-only, slew-only, or combined height and slew operations. By controlling the hydraulic movement of the machine, it prevents operators from accidentally hitting overhead powerlines, bridges, and tunnels, or swinging the machine’s boom into live rail corridors, road traffic, or adjacent structures.
