Acrow Props - Choosing The proper Prop For the Project

Posted November 04th, 2011 at 01:45pm

What on earth is An Acrow Prop?

Acrow props is visible on many construction sites and are generally helpful to support a structure or transfer lots. Construction props are usually familiar with support concrete form work whilst the concrete is curing in order to support a roof or overhead structure while removing, replacing or repairing a wall and other supporting structure. They can be an easy task to position and so are fully adjustable with in the height choice of the prop.

Acrow props

Acrow props involve two circular steel tubes, an inner tube with a top plate that slides top to bottom freely inside an outer tube that's attached to the base plate. The inner tube has holes down its length to enable you to quickly extend the inner tube just to below the required height and insert a steel pin to secure that length. To increase the prop on the correct height the top outer tube is threaded and a collar, and that is akin to a nut on a bolt, answers and supports the steel pin. So by rotating the collar and moving it it extends the inner prop. This lets you have the exact height required.

In regards to using Acrow Props on your project you do have a a few different choices to choose from. Acrow Props also come in 5 various sizes from the No.0 with a No.4, how do we pick the right prop for ones project?

Get started with Your Propping Height

Well the 1st step should be to go through the height or distance that you will be trying to prop. Do not use props which might be way too short by causing within the gap with timber or some other packer try to use the correct length prop for the task. Similarly, in case your propping distance is to the limit on the fully collapsed prop it may be ideal to select your next size into be certain that there is enough adjustment from the prop if there's a little variation on-site.

This table will be used being a general guide only as specifications can vary with various suppliers. Booking along with your supplier because of their specific specification.

No.0 -- 1050 - 1830 mm ( or 3.44 - 6.00 feet)
No.1 -- 1600 - 2800 mm ( or 5.25 - 9.18 feet)
No.2 -- 1900 - 3400 mm ( or 6.23 - 11.15 feet)
No.3 -- 2170 - 3975 mm ( or 7.12 - 13.04 feet)
No.4 -- 3100 - 4900 mm ( or 10.17 - 16.07 feet)

Estimate The Load That you should Support.

Your second step is usually to evaluate what load the prop has to support. You need to speak with your Engineer or any other responsible persons about the weight from the overhead structure to enable them to evaluate which loads need to be supported. In which the load is greater than the capability of merely one prop you need to use multiple props to increase the supported load in the given area.

This table will be used as being a general guide only as specifications will change with different suppliers. Booking with your supplier for their specific specification.

No.0 -- 22 - 42 KN -- 2243 - 4282 kg ( or 4945 - 9442 lbs)
No.1 -- 12 - 34 KN -- 1223 - 3467 kg ( or 2697 - 7643 lbs)
No.2 -- 11 - 39 KN -- 1121 - 3976 kg ( or 2472 - 8767 lbs)
No.3 --- 7 - 35 KN --- 713 - 3569 kg ( or 1573 - 7868 lbs)
No.4 --- 7 - 20 KN --- 713 - 2039 kg ( or 1573 - 4496 lbs)

Be certain that wherever you use a construction prop which the structure at their base plus the head with the prop are solid and sufficiently strong to compliment the wanted load. If there is any doubt the idea would have been a great idea to spread the impact in the prop using a spreader beam or plate.
