During that time, panels and loads have grown as Architects and Builders continued to push the frontiers in Tilt Slab construction.

Along the way, we've continued with further innovation.

You'll find we've improved the design, expanded the range, and adapted our approach to meet every challenge faced.

Reassuringly, many things have stayed the same, simply because they were right in the first place, and they're still right today.

Things like our trademark reinforced 16mm steel foot are often copied, but never bettered.

And we're still square instead of round, because kilo for kilo, square's still safer than round.

How do we know?

Shisham has the only purpose built prop testing rig capable of testing units up to 16 metres in length unto destruction.

For maximum quality control and efficiency, every Shisham prop is made in Australia, on-site at Shisham, by Shisham Staff.

All Shisham's components are continuously batch tested under a quality control program, and as an additional check, component testing is run by accredited NATA laboratories.

The end result?

With Shisham. you've got a prop proven nationally and continuously for over 20 years. A prop with every conceivable accessory.

An original you can count on.

Field Proven for over 20 years.

Why Square? To carry the same load, a square-shaped prop can be much smaller, lighter, and easier to use than a round-shaped one. They're also more stable and stackable.

Note WorkCoverAlert* concerning round shaped props: "Caution should be exercised when using tube type props on their own without transverse bracing due to their inherent lack of stability and relatively low capacity." *WorkCover Alert 5/98 Rev 1- September. Why a Steel Foot Instead Of Cast Iron? "Steel will have a higher ductility than that of cast iron, consequently the steel foot assembly will resist cracking to a greater degree than the cast iron." John Dryden, Technical Services Metallurgist, BHP.

Safe Working Load Recommendations
Two props/braces minimum per panel for stability and load transfer.

Both sections of props are permanently tagged with model and working load.
(WorkCover Alert 5/98).

Whenever possible the props/braces should be fixed to the panel before lifting.

Light Weight Fixed Panel Props

These Props are manufactured with a fixed length body which has a 200mm long Acme thread for adjustment to level panels in to position.

They are available in 2 models

1. Lightweight Fixed Prop which can be used for either composite panel walls or selected lightweight panels using some of the exotic concrete mixes that are available today.

2. Lightweight Plaster Prop: This unit has been designed to assist with the erection of plaster walls which require propping until the attachments or alignment has been finalised.

The Hercules™ props fixing procedures

We suggest that all units be fixed to J Bolts which have been integrated into the mesh prior to concrete being poured. After the prop has been removed, the excess is to be cut level to the floor.

Where the floor sections are using the pre-stressed cabling, the bolts are to be attached to plates and the plates cast in position for the attachment of the props.

In positions where the floor is already cast, then the procedure will require that the floor be drilled through and the bolt have a plate attached on the bottom side that will provide equal loading across the concrete area to which the prop will be attached.

All bolts shall be of K4140 grade and 8.8 strength. All steel plates shall be of a stucual grade of 350 steel. All washers shall be of structual material. Structual grade nuts should be used.
