The safe load for an offered prop differs accordance with the range in between its ends and the eccentricity of the load relative to the longitudinal axis of the prop.

The safe load for a BS requirement prop is an optimum of 35 kilonewtons (7,900 lbf) at a length of 2 metres (without utilizing any accessory and when not supported by horizontal lacing). Safe load is lowered when props are additional extended, or by up to half when the load is not concentrical.

Acrow props are mainly utilized for shoring: short-term assistances throughout structure repair work or modification work, rather than scaffolding: gain access to platforms for employees. A set of Acrow props are then utilized, one under each end.

The safe load for a BS requirement prop is an optimum of 35 kilonewtons (7,900 lbf) at a length of 2 metres (without utilizing any accessory and when not supported by horizontal lacing). Safe load is minimized when props are more extended, or by up to half when the load is not concentrical. A current enhancement to Acrow props was to form this baseplate with notches, enabling pallet loads of horizontal props to be stacked nicely, rather than arbitrarily stacked.

The initial Acrow prop was just planned for vertical assistance, the variety has actually because been extended. Shoring ‘push and pull’ props with rotating footplates are offered and are utilized to support concrete formwork.

The base and leading plate of Acrow props are rather little, so they appropriate for supporting a vertical load however are at threat of falling if there is any sideways force. In such cases, props must be strutted or ‘laced’ with scaffolding poles. A current enhancement to Acrow props was to form this baseplate with notches, permitting pallet loads of horizontal props to be stacked nicely, instead of arbitrarily stacked.
