Not all Acrow props are created equal. They come in a variety of lengths and even diameters. The maximum weight they can bear is around thirty-five kN, but this limit reduces when the props are fully extended. If the load is not precisely vertical on the prop, the load capacity will be compromised.
Some Acrow props have been designed for vertical shoring, including trenchwork. These are also known as ‘trench struts.’
If you need good quality shore props that are cost effective, the first step is to do your research. While ordering online can save you time, (and money), you should check the location of the company you intend to buy from. Shipping charges from overseas can substantially increase your total charges. As a rule, start local and widen your search based on the quanity you intent to buy. (1-5 City, 5-10 State, 10+ National). The increase in the cost of freight is then offset by the decrease in price from competion.
For example, if you are located in Australia, you should be looking online for Australia-based companies. One key is to check where sources and warehouses are based, because you might discover that a company officially located in New Zealand has a supplier from Australia. In this type of situation, you can go straight to the supplier yourself, especially if it is closer to home.
As with any purchase, you want to make sure you are getting real value for your money. Finding reviews of the company and its products from past customers is a good way to get a feel for what to expect. However, these should always be taken with a grain of salt, since the internet’s anonymity makes some people feel like they can say whatever they want.
