Mabey Heavy Prop
The Mabey Heavy Prop is a modular, high-load structural shoring system capable of supporting up to 490 kips on a single prop. The flexibility of the Mabey Heavy Prop system is provided by adjustable head and base units, which can be hydraulically preloaded using standard jack units. The system can be used for vertical, horizontal, bridge jacking or raking. The prop is based on four standard panel bridge chords secured into a square configuration via the prop chord connector. These prop bodies form the basis of a flexible, modular high load propping system.
The key to the system’s adaptability lies in the adjustable base and head units. These units allow up to 15.7″ adjustment in prop height. Jack seatings are provided within the head and base units to enable the preloading, jacking or releasing of props using standard hydraulic jacks. The basic props are complemented by a range of accessories including access bridges, raking shore adapters and header beams. Header beams are supplied in standard length.
The high load capacity, flexibility and speed of erection offered by the Mabey Heavy Prop system, together with its hydraulic preload and jacking facility, offers the ideal “off the shelf” solution to heavy shoring requirements.
Preloading is accomplished through the insertion of two or four hydraulic jacks at the head of each prop and the application of pressure until the desired preload is obtained. The adjustable screw is is tightened against the structure and the collar is locked into place. Jacks and their associated equipment may then be removed from the site altogether.
Offering a unique combination of strength, versatility and ease of erection, Mabey’s Universal® system represents one of the most adaptable solutions in our inventory.
