The Mabey Heavy Prop is a modular high load propping system capable of carrying up to 490 kips on a single prop. The flexibility of the Mabey Heavy Prop system is created by adjustable had and base units which can be hydraulically preloaded using standard jack units. It can be used for vertical, horizontal or raking applications.

The prop is based on four standard panel bridge chords connected into a square configuration using the prop chord connector. These prop bodies form the basis of a flexible, modular high load propping system.

The key to the system's flexibility 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.
