Acrow Prop

A range of adjustable “telescopic props” are designed for multiple uses in the construction industry, including:

Falsework support: formwork for reinforced concrete slabs and framework beams.
Raking shores: to brace formwork for columns, walls, and stairs.
Temporary support: for repair work, canopies, lintels, and the like.

Acrow Prop System Details

The Acrow Prop system consists of four major components designed to be joined or bolted to suit the application:

A range of six Telescopic Props
U-Head
Prop Pivot End Adapter
Raking Shore Foot Bracket

Acrow Prop Specifications

Acrow Prop offer a range of props capable for supporting formwork ranging from 720mm to 4900mm high. Manufactured form high tensile steel, the prop consists of four parts:

The outer tube with welded base-plate
The inner tube with welded top-plate
The nut and handle
The chain less prop pin

The prop outer tube is 60.3 OD tube x 3.6mm thick with a 300mm rolled thread and slot. Within the specified range, each prop can be finely adjusted thanks to the rolling thread and slot. The rolled thread retains the wall thickness of the tube, thus maintaining maximum strength. A reduction couplers enables a standard scaffold tube to be connected to the ACROW PROP outer tube for bracing purposes. The prop inner tube is 48.3 OD x 3.6mm thick for props No. 00 to No. 03 and 3.9mm thick for prop No. 4. The prop inner tube has a series of Ø17.5 holes spaced at 152.5mm increments, which provide the major adjustment for the prop height. Inner tube diameter enables standard scaffold tubes and couplers to be used for bracing purposes.

Prop Nut

A handle-equipped Grade 480, Ø61mm ACME threaded nut made of zinc-plated cast steel. The primary purpose of the prop nut is to engage the outer and inner tubes and finalize the prop height adjustment. The prop nut ACME thread has several benefits, such as faster clamping, fewer threads per axial distance, stronger and longer-lasting resistance to thread wear and stripping, and higher thread shear capacity

Prop Pin

High tensile pin with solid steel loop. A main feature in the chainless Acrow Prop, structurally engaging both the outer and inner props tubes. The Prop Pin eliminates the need for any tangled or lost chains and reduces loss of pins on the construction site.

Prop pin

It is important correctly positioning the pin and its loop. The loop should be facing upward where the blow on end of loop will push the loop against prop outer and not dislodge the pin. Incorrectly placing the pin, its loop is facing downward, when the loop is struck by a blow on its end it would result in load being transmitted to end of pin causing it to push out of the prop.

U-Head Detachable Spigot

To support the joist or bearing, the detachable U-Head Spigot is intended to be placed into the Acrow Prop Inner Tube Top-Plate.

U-Heads don’t only support the horizontal bearer, but also ensure the bearers are centrally located to reduce any eccentricity present. The U-Head can be rotated to centre the bearer or the packer can be used for the same purpose.
